?論壇上看了不少Spring Security的相關文章。這些文章基本上都還是基于Acegi-1.X的配置方式，而主要的配置示例也來自于SpringSide的貢獻。 搭建基礎環境 http://www.javaeye.com/wiki/struts2/1321-struts2-development-environment-to-build 參考文檔 http://www.family168.com/tutorial/springsecurity/html/springsecurity.html Spring Security基本配置 最小化配置 1. 在web.xml文件中加入Filter聲明
Xml代碼
?? < filter > ????< filter-name > </ filter-name > ????< filter-class > </ filter-class > </ filter > < filter-mapping > ????< filter-name > </ filter-name > ????< url-pattern > </ url-pattern > </ filter-mapping >
<!-- Spring security Filter -->
<filter><filter-name>springSecurityFilterChain</filter-name><filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping><filter-name>springSecurityFilterChain</filter-name><url-pattern>/*</url-pattern>
</filter-mapping>
2. 使用最小的<http>配置
Xml代碼
< http auto-config 'true' > ????< intercept-url pattern "/**" access "ROLE_USER" /> </ http >
<http auto-config='true'><intercept-url pattern="/**" access="ROLE_USER" />
</http>
3. 配置UserDetailsService來指定用戶和權限
Xml代碼
< authentication-provider > ????< user-service > ??????< user name "downpour" password "downpour" authorities "ROLE_USER,?ROLE_ADMIN" /> ??????< user name "robbin" password "robbin" authorities "ROLE_USER" /> ??????< user name "QuakeWang" password "QuakeWang" authorities "ROLE_ADMIN" /> ????</ user-service > ??</ authentication-provider >
<authentication-provider><user-service><user name="downpour" password="downpour" authorities="ROLE_USER, ROLE_ADMIN" /><user name="robbin" password="robbin" authorities="ROLE_USER" /><user name="QuakeWang" password="QuakeWang" authorities="ROLE_ADMIN" /></user-service></authentication-provider>
4. 小結 剖析基本配置元素 1. 有關auto-config屬性
Xml代碼
< http > ????< intercept-url pattern "/**" access "ROLE_USER" /> ????< form-login /> ????< anonymous /> ????< http-basic /> ????< logout /> ????< remember-me /> </ http >
<http><intercept-url pattern="/**" access="ROLE_USER" /><form-login /><anonymous /><http-basic /><logout /><remember-me />
</http>
2. 與Acegi的比較
Xml代碼
< form-login login-page "/login.jsp" authentication-failure-url "/login.jsp?error=true" default-target-url "/work" />
<form-login login-page="/login.jsp" authentication-failure-url="/login.jsp?error=true" default-target-url="/work" />
Xml代碼
< bean id "authenticationProcessingFilter" ??????????class "org.acegisecurity.ui.webapp.AuthenticationProcessingFilter" > ????< property name "authenticationManager" ??????????????????ref "authenticationManager" /> ????< property name "authenticationFailureUrl" ??????????????????value "/login.jsp?error=1" /> ????< property name "defaultTargetUrl" value "/work" /> ????< property name "filterProcessesUrl" ??????????????????value "/j_acegi_security_check" /> ????< property name "rememberMeServices" ref "rememberMeServices" /> </ bean >
<bean id="authenticationProcessingFilter"class="org.acegisecurity.ui.webapp.AuthenticationProcessingFilter"><property name="authenticationManager"ref="authenticationManager"/><property name="authenticationFailureUrl"value="/login.jsp?error=1"/><property name="defaultTargetUrl" value="/work"/><property name="filterProcessesUrl"value="/j_acegi_security_check"/><property name="rememberMeServices" ref="rememberMeServices"/>
</bean>
3. 過濾器鏈在哪里
Xml代碼
< bean id "filterChainProxy" ??????????class "org.acegisecurity.util.FilterChainProxy" > ????< property name "filterInvocationDefinitionSource" > ????????< value > ????????????????CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISON ?? ????????????????PATTERN_TYPE_APACHE_ANT????????????????? ?? ????????????????/common/**=#NONE#? ?? ????????????????/css/**=#NONE#? ?? ????????????????/images/**=#NONE# ?? ????????????????/js/**=#NONE#? ?? ????????????????/login.jsp ????????????????/**=httpSessionContextIntegrationFilter,logoutFilter,authenticationProcessingFilter,securityContextHolderAwareRequestFilter,exceptionTranslationFilter,filterSecurityInterceptor ?? ????????</ value > ????</ property > </ bean >
<bean id="filterChainProxy"class="org.acegisecurity.util.FilterChainProxy"><property name="filterInvocationDefinitionSource"><value>CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISONPATTERN_TYPE_APACHE_ANT /common/**=#NONE# /css/**=#NONE# /images/**=#NONE#/js/**=#NONE# /login.jsp=#NONE#/**=httpSessionContextIntegrationFilter,logoutFilter,authenticationProcessingFilter,securityContextHolderAwareRequestFilter,exceptionTranslationFilter,filterSecurityInterceptor</value></property>
</bean>
你不能替換那些<http>元素自己使用而創建出的過濾器，比如HttpSessionContextIntegrationFilter, ExceptionTranslationFilter 或 FilterSecurityInterceptor
Xml代碼
< beans:bean id "myFilter" class "com.mycompany.MySpecialAuthenticationFilter" > ????< custom-filter position "AUTHENTICATION_PROCESSING_FILTER" /> </ beans:bean >
<beans:bean id="myFilter" class="com.mycompany.MySpecialAuthenticationFilter"><custom-filter position="AUTHENTICATION_PROCESSING_FILTER"/>
</beans:bean>
對于在http/intercept-url中沒有進行定義的URL，將會默認使用系統內置的過濾器鏈進行權限認證。 所以，你并不需要在http/intercept-url中額外定義一個類似/**的匹配規則。 使用數據庫對用戶和權限進行管理 用戶和權限的關系設計
Java代碼
CREATE?TABLE?users?( ?? ??username?VARCHAR(50 ??password?VARCHAR(50 ??enabled?BIT?NOT?NULL ?? ); ?? ?? CREATE?TABLE?authorities?( ?? ??username?VARCHAR(50 ??authority?VARCHAR(50 );??
CREATE TABLE users (username VARCHAR(50) NOT NULL PRIMARY KEY,password VARCHAR(50) NOT NULL,enabled BIT NOT NULL
);CREATE TABLE authorities (username VARCHAR(50) NOT NULL,authority VARCHAR(50) NOT NULL
);
Java代碼
CREATE?TABLE?`user`?( ?? ??`id`?int 11 ??`name`?varchar(255 default ??`password`?varchar(255 default ??`disabled`?int 1 ??PRIMARY?KEY??(`id`) ?? )?ENGINE=InnoDB?DEFAULT?CHARSET=utf8; ?? ?? CREATE?TABLE?`role`?( ?? ??`id`?int 11 ??`name`?varchar(255 default ??PRIMARY?KEY??(`id`) ?? )?ENGINE=InnoDB?DEFAULT?CHARSET=utf8; ?? ?? CREATE?TABLE?`user_role`?( ?? ??`user_id`?int 11 ??`role_id`?int 11 ??PRIMARY?KEY??(`user_id`,`role_id`), ?? ??UNIQUE?KEY?`role_id`?(`role_id`), ?? ??KEY?`FK143BF46AF6AD4381`?(`user_id`), ?? ??KEY?`FK143BF46A51827FA1`?(`role_id`), ?? ??CONSTRAINT?`FK143BF46A51827FA1`?FOREIGN?KEY?(`role_id`)?REFERENCES?`role`?(`id`), ?? ??CONSTRAINT?`FK143BF46AF6AD4381`?FOREIGN?KEY?(`user_id`)?REFERENCES?`user`?(`id`) ?? )?ENGINE=InnoDB?DEFAULT?CHARSET=utf8;??
CREATE TABLE `user` (`id` int(11) NOT NULL auto_increment,`name` varchar(255) default NULL,`password` varchar(255) default NULL,`disabled` int(1) NOT NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;CREATE TABLE `role` (`id` int(11) NOT NULL auto_increment,`name` varchar(255) default NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;CREATE TABLE `user_role` (`user_id` int(11) NOT NULL,`role_id` int(11) NOT NULL,PRIMARY KEY (`user_id`,`role_id`),UNIQUE KEY `role_id` (`role_id`),KEY `FK143BF46AF6AD4381` (`user_id`),KEY `FK143BF46A51827FA1` (`role_id`),CONSTRAINT `FK143BF46A51827FA1` FOREIGN KEY (`role_id`) REFERENCES `role` (`id`),CONSTRAINT `FK143BF46AF6AD4381` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
通過配置SQL來模擬用戶和權限
Xml代碼
< authentication-provider > ????< jdbc-user-service data-source-ref "dataSource" ????users-by-username-query "SELECT?U.username,?U.password,?U.accountEnabled?AS?'enabled'?FROM?User?U?where?U.username=?" ????authorities-by-username-query "SELECT?U.username,?R.name?as?'authority'?FROM?User?U?JOIN?Authority?A?ON?u.id?=?A.userId?JOIN?Role?R?ON?R.id?=?A.roleId?WHERE?U.username=?" /> </ authentication-provider >
<authentication-provider><jdbc-user-service data-source-ref="dataSource"users-by-username-query="SELECT U.username, U.password, U.accountEnabled AS 'enabled' FROM User U where U.username=?"authorities-by-username-query="SELECT U.username, R.name as 'authority' FROM User U JOIN Authority A ON u.id = A.userId JOIN Role R ON R.id = A.roleId WHERE U.username=?"/>
</authentication-provider>
通過擴展Spring Security的默認實現來進行用戶和權限的管理
Java代碼
public interface extends ???? ?? ????GrantedAuthority[]?getAuthorities(); ?? ?? ????String?getPassword(); ?? ?? ????String?getUsername(); ?? ?? ????boolean ?? ????boolean ?? ????boolean ?? ????boolean }??
public interface UserDetails extends Serializable {GrantedAuthority[] getAuthorities();String getPassword();String getUsername();boolean isAccountNonExpired();boolean isAccountNonLocked();boolean isCredentialsNonExpired();boolean isEnabled();
}
?
Java代碼
public interface ????UserDetails?loadUserByUsername(String?username) ?? ????????throws }??
public interface UserDetailsService {UserDetails loadUserByUsername(String username)throws UsernameNotFoundException, DataAccessException;
}
1. 定義User類和Role類，使他們之間形成多對多的關系
Java代碼
@Entity @Proxy false @Cache public class ???? ?? ????private static final long ?? ????@Id ????@GeneratedValue ????private ???? ?? ????private ???? ?? ????private ???? ?? ????private boolean ???? ?? ????@ManyToMany class ????@JoinTable "user_role" @JoinColumn "user_id" @JoinColumn "role_id" ????@Cache ????private ?? ?????????? }??
@Entity
@Proxy(lazy = false)
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class User {private static final long serialVersionUID = 8026813053768023527L;@Id@GeneratedValueprivate Integer id;private String name;private String password;private boolean disabled;@ManyToMany(targetEntity = Role.class, fetch = FetchType.EAGER)@JoinTable(name = "user_role", joinColumns = @JoinColumn(name = "user_id"), inverseJoinColumns = @JoinColumn(name = "role_id"))@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)private Set<Role> roles;// setters and getters
}
?
Java代碼
@Entity @Cache public class ???? ?? ????@Id ????@GeneratedValue ????private ???? ?? ????private ???????? ?? ?????????? }??
@Entity
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class Role {@Id@GeneratedValueprivate Integer id;private String name;// setters and getters
}
2. 使User類實現UserDetails接口
Java代碼
@Entity @Proxy false @Cache public class implements ???? ?? ????private static final long ?? ????@Id ????@GeneratedValue ????private ???? ?? ????private ???? ?? ????private ???? ?? ????private boolean ???? ?? ????@ManyToMany class ????@JoinTable "user_role" @JoinColumn "user_id" @JoinColumn "role_id" ????@Cache ????private ???? ?? ????? ? ?? ????public ???????? ?? ????} ?? ?? ????? ? ?? ????public ????????List<GrantedAuthority>?grantedAuthorities?=?new ????????for ????????????grantedAuthorities.add(new ????????} ?? ????????return new ????} ?? ?? ????? ? ?? ????public ????????return ????} ?? ?? ????? ? ?? ????public ????????return ????} ?? ?? ????? ? ?? ????public boolean ????????return true ????} ?? ?? ????? ? ?? ????public boolean ????????return true ????} ?? ?? ????? ? ?? ????public boolean ????????return true ????} ?? ?? ????? ? ?? ????public boolean ????????return this ????} ?? ?????? ?? ???????? }??
@Entity
@Proxy(lazy = false)
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class User implements UserDetails {private static final long serialVersionUID = 8026813053768023527L;@Id@GeneratedValueprivate Integer id;private String name;private String password;private boolean disabled;@ManyToMany(targetEntity = Role.class, fetch = FetchType.EAGER)@JoinTable(name = "user_role", joinColumns = @JoinColumn(name = "user_id"), inverseJoinColumns = @JoinColumn(name = "role_id"))@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)private Set<Role> roles;/*** The default constructor*/public User() {}/* (non-Javadoc)* @see org.springframework.security.userdetails.UserDetails#getAuthorities()*/public GrantedAuthority[] getAuthorities() {List<GrantedAuthority> grantedAuthorities = new ArrayList<GrantedAuthority>(roles.size());for(Role role : roles) {grantedAuthorities.add(new GrantedAuthorityImpl(role.getName()));}return grantedAuthorities.toArray(new GrantedAuthority[roles.size()]);}/* (non-Javadoc)* @see org.springframework.security.userdetails.UserDetails#getPassword()*/public String getPassword() {return password;}/* (non-Javadoc)* @see org.springframework.security.userdetails.UserDetails#getUsername()*/public String getUsername() {return name;}/* (non-Javadoc)* @see org.springframework.security.userdetails.UserDetails#isAccountNonExpired()*/public boolean isAccountNonExpired() {return true;}/* (non-Javadoc)* @see org.springframework.security.userdetails.UserDetails#isAccountNonLocked()*/public boolean isAccountNonLocked() {return true;}/* (non-Javadoc)* @see org.springframework.security.userdetails.UserDetails#isCredentialsNonExpired()*/public boolean isCredentialsNonExpired() {return true;}/* (non-Javadoc)* @see org.springframework.security.userdetails.UserDetails#isEnabled()*/public boolean isEnabled() {return !this.disabled;}// setters and getters
}
Java代碼
? ? ?? public ????List<GrantedAuthority>?grantedAuthorities?=?new ????for ????????grantedAuthorities.add(new ????????} ?? ????????return new }??
/* (non-Javadoc)* @see org.springframework.security.userdetails.UserDetails#getAuthorities()*/
public GrantedAuthority[] getAuthorities() {List<GrantedAuthority> grantedAuthorities = new ArrayList<GrantedAuthority>(roles.size());for(Role role : roles) {grantedAuthorities.add(new GrantedAuthorityImpl(role.getName()));}return grantedAuthorities.toArray(new GrantedAuthority[roles.size()]);
}
Xml代碼
< user name "downpour" password "downpour" authorities "ROLE_USER,?ROLE_ADMIN" />
<user name="downpour" password="downpour" authorities="ROLE_USER, ROLE_ADMIN" />
3. 實現UserDetailsService接口
Java代碼
@Repository "securityManager" public class extends implements ?? ????? ? ? ? ?? ????@Autowired ????public void ????????super ????} ?? ?? ????public throws ????????List<User>?users?=?getHibernateTemplate().find("FROM?User?user?WHERE?user.name?=???AND?user.disabled?=?false" ????????if ????????????throw new "User?" "?has?no?GrantedAuthority" ????????} ?? ????????return 0 ????} ?? }??
@Repository("securityManager")
public class SecurityManagerSupport extends HibernateDaoSupport implements UserDetailsService {/*** Init sessionFactory here because the annotation of Spring 2.5 can not support override inject* * @param sessionFactory*/@Autowiredpublic void init(SessionFactory sessionFactory) {super.setSessionFactory(sessionFactory);}public UserDetails loadUserByUsername(String userName) throws UsernameNotFoundException, DataAccessException {List<User> users = getHibernateTemplate().find("FROM User user WHERE user.name = ? AND user.disabled = false", userName);if(users.isEmpty()) {throw new UsernameNotFoundException("User " + userName + " has no GrantedAuthority");}return users.get(0);}
}
4. 配置文件
Xml代碼
< authentication-provider user-service-ref "securityManager" > ????< password-encoder hash "md5" /> </ authentication-provider >
<authentication-provider user-service-ref="securityManager"><password-encoder hash="md5"/>
</authentication-provider>
使用數據庫對資源進行管理 權限和資源的設計
Java代碼
CREATE?TABLE?`role`?( ?? ??`id`?int 11 ??`name`?varchar(255 default ??`description`?varchar(255 default ??PRIMARY?KEY??(`id`) ?? )?ENGINE=InnoDB?DEFAULT?CHARSET=utf8; ?? ?? CREATE?TABLE?`resource`?( ?? ??`id`?int 11 ??`type`?varchar(255 default ??`value`?varchar(255 default ??PRIMARY?KEY??(`id`) ?? )?ENGINE=InnoDB?DEFAULT?CHARSET=utf8; ?? ?? CREATE?TABLE?`role_resource`?( ?? ??`role_id`?int 11 ??`resource_id`?int 11 ??PRIMARY?KEY??(`role_id`,`resource_id`), ?? ??KEY?`FKAEE599B751827FA1`?(`role_id`), ?? ??KEY?`FKAEE599B7EFD18D21`?(`resource_id`), ?? ??CONSTRAINT?`FKAEE599B751827FA1`?FOREIGN?KEY?(`role_id`)?REFERENCES?`role`?(`id`), ?? ??CONSTRAINT?`FKAEE599B7EFD18D21`?FOREIGN?KEY?(`resource_id`)?REFERENCES?`resource`?(`id`) ?? )?ENGINE=InnoDB?DEFAULT?CHARSET=utf8;??
CREATE TABLE `role` (`id` int(11) NOT NULL auto_increment,`name` varchar(255) default NULL,`description` varchar(255) default NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;CREATE TABLE `resource` (`id` int(11) NOT NULL auto_increment,`type` varchar(255) default NULL,`value` varchar(255) default NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;CREATE TABLE `role_resource` (`role_id` int(11) NOT NULL,`resource_id` int(11) NOT NULL,PRIMARY KEY (`role_id`,`resource_id`),KEY `FKAEE599B751827FA1` (`role_id`),KEY `FKAEE599B7EFD18D21` (`resource_id`),CONSTRAINT `FKAEE599B751827FA1` FOREIGN KEY (`role_id`) REFERENCES `role` (`id`),CONSTRAINT `FKAEE599B7EFD18D21` FOREIGN KEY (`resource_id`) REFERENCES `resource` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
針對資源的認證 我們可以再實現一個類似的過濾器，并將我們自己的過濾器作為一個customer-filter，加到默認的過濾器鏈的最后，從而完成整個過濾檢查。

Spring Security對象的訪問 1. 訪問當前登錄用戶
Java代碼
public class ?? ????? ? ? ? ?? ????public static ????????return ????} ?? ?? }??
public class SecurityUserHolder {/*** Returns the current user* * @return*/public static User getCurrentUser() {return (User) SecurityContextHolder.getContext().getAuthentication().getPrincipal();}}
2. 訪問當前登錄用戶所擁有的權限
Java代碼
? ? ?? public ????List<GrantedAuthority>?grantedAuthorities?=?new ????for ????????grantedAuthorities.add(new ????} ?? ???????return new } ?? ?? ? ? ? ? ? ? ? ? ?? public ????List<String>?authorities?=?new ????for this ????????authorities.add(authority.getAuthority()); ?? ????} ?? ????return "," }??
/* (non-Javadoc)* @see org.springframework.security.userdetails.UserDetails#getAuthorities()*/public GrantedAuthority[] getAuthorities() {List<GrantedAuthority> grantedAuthorities = new ArrayList<GrantedAuthority>(roles.size());for(Role role : roles) {grantedAuthorities.add(new GrantedAuthorityImpl(role.getName()));}return grantedAuthorities.toArray(new GrantedAuthority[roles.size()]);}/*** Returns the authorites string* * eg. * downpour --- ROLE_ADMIN,ROLE_USER* robbin --- ROLE_ADMIN* * @return*/public String getAuthoritiesString() {List<String> authorities = new ArrayList<String>();for(GrantedAuthority authority : this.getAuthorities()) {authorities.add(authority.getAuthority());}return StringUtils.join(authorities, ",");}
3. 訪問當前登錄用戶能夠訪問的資源
/*** @return the roleResources*/
public Map<String, List<Resource>> getRoleResources() {// init roleResources for the first timeif(this.roleResources == null) { this.roleResources = new HashMap<String, List<Resource>>();for(Role role : this.roles) {String roleName = role.getName();Set<Resource> resources = role.getResources();for(Resource resource : resources) {String key = roleName + "_" + resource.getType();if(!this.roleResources.containsKey(key)) {this.roleResources.put(key, new ArrayList<Resource>());}this.roleResources.get(key).add(resource); }}}return this.roleResources;
}
