（文章所使用框架Spring+SpringMVC+Mybatis，為項目結構圖參照文章末尾）

1、創建maven工程，在pom.xml文件中導入需要的jar包依賴：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

2、整合SpringMVC：

（1）在web.xml文件中配置前端控制器：

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"id="serviceMarket" version="2.5"><display-name>ssm-test</display-name><welcome-file-list><welcome-file>index.html</welcome-file><welcome-file>index.htm</welcome-file><welcome-file>index.jsp</welcome-file><welcome-file>default.html</welcome-file><welcome-file>default.htm</welcome-file><welcome-file>default.jsp</welcome-file></welcome-file-list><!-- 加載spring相關配置文件 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring/applicationContext*.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener> <!-- 解決post亂碼 --><filter><filter-name>CharacterEncodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param></filter><filter-mapping><filter-name>CharacterEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- springmvc的前端控制器 --><servlet><servlet-name>ssm-test</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- 加載springmvc的配置文件(處理器映射器、處理器適配器等等) --><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring/springmvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>ssm-test</servlet-name><url-pattern>/</url-pattern></servlet-mapping></web-app>

（2）編寫springmvc.xml文件：

在文件中配置與springmvc框架相關的配置，比如：springmvc.xml約束、處理器映射器、處理器適配器、視圖解析器、Handler等配置。

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"><!-- 使用注解驅動：自動配置處理器映射器與處理器適配器 --><mvc:annotation-driven /><!-- 注解方式：配置Handler，自動掃描該包，使SpringMVC認為包下用了@controller注解的類是控制器 --><!-- 批量加載：組件掃描方式： --><context:component-scan base-package="com.zwp.controller" /><!-- 視圖解析器：解析jsp頁面，默認使用jstl標簽，classpath下得有jstl的包 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><!-- 配置前后綴 --><property name="prefix" value="/WEB-INF/jsp/"></property><property name="suffix" value=".jsp"></property></bean><!-- 靜態資源處理，不攔截靜態資源，如css、js、imgs --><mvc:resources location="/static/css/" mapping="/static/css/**"/><mvc:resources location="/static/js/" mapping="/static/js/**"/><mvc:resources location="/static/img/" mapping="/static/img/**"/><!-- 文件上傳相關配置 --><bean id="multipartResolver"class="org.springframework.web.multipart.commons.CommonsMultipartResolver"><property name="defaultEncoding" value="UTF-8"></property><property name="maxUploadSize" value="10240000"></property></bean> </beans>

（3）編寫Handler：

//User類的Handler //需要在類上面加@Controller注解，這樣才能被自動掃描到 @Controller @RequestMapping("/user") public class UserController {private static Logger log=LoggerFactory.getLogger(UserController.class);@RequestMapping(value="/login",method=RequestMethod.GET) public String login(HttpServletRequest request,Model model){ String username = request.getParameter("username"); String password = request.getParameter("password");System.out.println("username:"+username+";password:"+password);User user=null;if (username.equals("zwp") && password.equals("123456")) {user = new User(); user.setAge(11);user.setId(1);user.setPassword("123456");user.setUsername("zwp");log.debug(user.toString());}model.addAttribute("user", user); return "index"; } } //User實體類 public class User {private Integer id;private String username;private String password;private Integer age;public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}@Overridepublic String toString() {return "User [id=" + id + ", username=" + username + ", password=" + password + ", age=" + age + "]";} }

（4）配置日志文件：

在項目根目錄下面創建log4j.properties日志文件，下面是日志文件的基本配置，可以滿足大多數項目的需求。

log4j.rootLogger=INFO,Console,File #定義日志輸出目的地為控制臺 log4j.appender.Console=org.apache.log4j.ConsoleAppender log4j.appender.Console.Target=System.out #可以靈活地指定日志輸出格式，下面一行是指定具體的格式 log4j.appender.Console.layout = org.apache.log4j.PatternLayout log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n #文件大小到達指定尺寸的時候產生一個新的文件 log4j.appender.File = org.apache.log4j.RollingFileAppender #指定輸出目錄 log4j.appender.File.File = logs/ssm.log #定義文件最大大小 log4j.appender.File.MaxFileSize = 10MB # 輸出所以日志，如果換成DEBUG表示輸出DEBUG以上級別日志 log4j.appender.File.Threshold = ALL log4j.appender.File.layout = org.apache.log4j.PatternLayout log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

（5）啟動項目，進行測試：

訪問地址：http://localhost:8080/ssm/user/login?username=zwp&password=123456，如果出現下面頁面則代表映射成功。

?

至此，SpringMVC的配置就已經成功。

3、Spring和Mybatis框架的整合：

整合思路：由Spring通過單例方式管理SqlSessionFactory；spring和mybatis整合生成代理對象，使用SqlSessionFactory創建SqlSession，持久層的mapper都需要有spring進行管理。

（1）配置dao層，即配置sqlSessionFactory：（我的配置在applicationContext-dao.xml文件中）

<beans xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsdhttp://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"><!-- 1.加載配置文件 --><!-- 第一種加載多個.properties文件的方法 --><context:property-placeholder location="classpath:resource/*.properties"/><!-- 2.配置數據庫連接池 --><bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"destroy-method="close"><property name="url" value="${jdbc.url}" /><property name="username" value="${jdbc.username}" /><property name="password" value="${jdbc.password}" /><property name="driverClassName" value="${jdbc.driver}" /><property name="maxActive" value="10" /><property name="minIdle" value="5" /></bean><!-- 3.讓spring創建并管理sqlsessionfactory，使用mybatis和spring整合包中的 --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><!-- 配置數據源，數據庫連接池 --><property name="dataSource" ref="dataSource" /><!-- 加載mybatis的全局配置文件 --><property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" /></bean><!-- 4.mapper批量掃描：從mapper包中掃描出mapper,自動創建代理對象并且在spring容器中注冊需要遵循規范：mapper接口類名和mapper.xml映射文件名稱一致，且在同一目錄下，自動掃描出來的mapper的bean的id為類名(首字母小寫)--><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="com.zwp.mapper" /></bean> </beans>

創建并編寫SqlMapConfig.xml文件：

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration><plugins><!-- com.github.pagehelper為PageHelper類所在包名 --><plugin interceptor="com.github.pagehelper.PageHelper"><!-- 設置數據庫類型 Oracle,Mysql,MariaDB,SQLite,Hsqldb,PostgreSQL六種數據庫 --><property name="dialect" value="mysql" /></plugin></plugins> </configuration>

（2）配置service層：（我的配置在applicationContext-service.xml文件中）

<beans xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsdhttp://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"><!-- 自動掃描service層的接口與實現類 --><context:component-scan base-package="com.zwp.service" /> </beans>

（3）配置事務：（我的配置在applicationContext-trans.xml文件中）

<beans xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsdhttp://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"><!-- 事務管理器 --><bean id="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><!-- 數據源 --><property name="dataSource" ref="dataSource" /></bean><!-- 通知 --><tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><!-- 傳播行為 --><tx:method name="add*" propagation="REQUIRED" /><tx:method name="create*" propagation="REQUIRED" /><tx:method name="insert*" propagation="REQUIRED" /><tx:method name="save*" propagation="REQUIRED" /><tx:method name="update*" propagation="REQUIRED" /><tx:method name="delete*" propagation="REQUIRED" /><tx:method name="find*" propagation="SUPPORTS" read-only="true" /><tx:method name="select*" propagation="SUPPORTS" read-only="true" /><tx:method name="get*" propagation="SUPPORTS" read-only="true" /></tx:attributes></tx:advice><!-- 切面 --><aop:config><aop:advisor advice-ref="txAdvice"pointcut="execution(* com.zwp.service.*.*(..))" /></aop:config> </beans>

至此，Spring和Mybatis框架的整合就完成了。

?

4、測試：

（1）創建測試用表：

（2）利用MyBatis-Generator自動創建實體類、Mybatis映射文件以及Dao接口。

（3）建立Service和實現類：

//UserService接口類： @Service public interface UserService {public User getUserById(int userId);} //UserService的實現類 @Service public class UserServiceImpl implements UserService {//注入UserMapper接口@Autowiredprivate UserMapper userMapper;@Overridepublic User getUserById(int userId) {User user = userMapper.selectByPrimaryKey(userId);return user;} }

（3）建立UserController類：

//User類的Handler //需要在類上面加@Controller注解，這樣才能被自動掃描到 @Controller @RequestMapping("/user") public class UserController {@Autowiredprivate UserService userService;private static Logger log=LoggerFactory.getLogger(UserController.class);@RequestMapping(value="/getUserById/{userId}",method=RequestMethod.GET)public @ResponseBody User getUserById(@PathVariable Integer userId){return userService.getUserById(userId);}@RequestMapping(value="/login",method=RequestMethod.GET) public String login(HttpServletRequest request,Model model){ String username = request.getParameter("username"); String password = request.getParameter("password");System.out.println("username:"+username+";password:"+password);User user=null;if (username.equals("zwp") && password.equals("123456")) {user = new User(); user.setAge(11);user.setId(1);user.setPassword("123456");user.setUsername("zwp");log.debug(user.toString());}model.addAttribute("user", user); return "index"; } }

（4）部署項目，輸入地址：http://localhost:8080/ssm/user/getUserById/2，出現下面響應結果，則表示整合成功了。

?

至此，Maven+Spring+SpringMVC+Mybatis的整合就完成了。
