maven 包的导入
軟件152 李升星
一、maven 包的導入
清單如下：
<!-- Inherit defaults from Spring Boot -->
? <parent>
? <groupId>org.springframework.boot</groupId>
? <artifactId>spring-boot-starter-parent</artifactId>
? <version>1.3.1.BUILD-SNAPSHOT</version>
? </parent>
<!-- Add typical dependencies for a web application -->
??? <dependencies>
???? <dependency>
???? <groupId>org.springframework.boot</groupId>
???? <artifactId>spring-boot-starter-web</artifactId>
??????? </dependency>
??????? <!-- spring data jpa -->
?????? ?<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<!-- mysql driver -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
??????? <!-- 其他依賴 -->
??????? <dependency>
<groupId>javax.persistence</groupId>
<artifactId>persistence-api</artifactId>
<version>1.0.2</version>
</dependency>
??? </dependencies>
??? <!-- Package as an executable jar -->
??? <build>
???? <plugins>
???? <plugin>
?? ?????????????<groupId>org.springframework.boot</groupId>
??????????????? <artifactId>spring-boot-maven-plugin</artifactId>
??????????? </plugin>
??????????? <!-- 編譯器版本指定 -->
??????????? <plugin>?
??????? <groupId>org.apache.maven.plugins</groupId>?
???? ???<artifactId>maven-compiler-plugin</artifactId>?
??????? <configuration>?
????????? <source>1.7</source>?
????????? <target>1.7</target>?
??????? </configuration>?
????? </plugin>?
??????? </plugins>
??? </build>
??? <!-- Add Spring repositories -->
??? <pluginRepositories>
??????? <pluginRepository>
??????????? <id>spring-snapshots</id>
??????????? <url>http://repo.spring.io/snapshot</url>
??????? </pluginRepository>
??????? <pluginRepository>
??????????? <id>spring-milestones</id>
??????????? <url>http://repo.spring.io/milestone</url>
??????? </pluginRepository>
??? </pluginRepositories>
??? <repositories>
??????? <repository>
??????????? <id>spring-snapshots</id>
??????????? <url>http://repo.spring.io/snapshot</url>
??????????? <snapshots><enabled>true</enabled></snapshots>
??????? </repository>
??????? <repository>
??????????? <id>spring-milestones</id>
??????????? <url>http://repo.spring.io/milestone</url>
??????? </repository>
??? </repositories>
以上為整個spring boot 構建簡單web項目所需要的maven配置文件。
二、創建實體類
package com.whucker.platform.domain;
@Entity //實體
@Table(name="t_user") //指定表名
public class User {
??? @Id //定義主鍵id
??? @GeneratedValue(strategy=GenerationType.AUTO) //自增
??? private Long id;
??? private String name;
??? private int age;
??? private int gender;
??? //...此處省略get/set
}
Repository代碼(此處使用的是spring data jpa，由于該文章主要講解spring boot，所有不在此對jpa做解釋)
package com.whucker.platform.repository;
public interface UserRepository extends CrudRepository<User, Long>{
}
接口定義
package com.whucker.platform.service;
public interface IUserService {
??? //添加
??? void save(User user);
??? //刪除
??? void delete(Long id);
??? //修改
??? void update(User user);
??? //查詢單個對象
??? User findOne(Long id);
??? //查詢所有
??? List<User> findAll();
}
接口實現
package com.whucker.platform.service.impl;
@Service(value="userService")
@Transactional
public class UserServiceImpl implements IUserService{
??? @Autowired
??? private UserRepository userRepository;
??? @Override
??? public void save(User user) {
??????? this.userRepository.save(user);
??? }
}
?
控制層
package com.whucker.platform.controler;
@RestController
public class IndexManageAction {
??? @RequestMapping(value="/")
??? public String index(){
??????? return "歡迎訪問首頁!";
??? }
}
三、Application類
ackage com.whucker.platform;
@SpringBootApplication
public class Application {
??? public static void main(String[] args) {
??????? SpringApplication.run(Application.class);
}
配置文件
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/spring-boot-db
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
