1、添加依赖新建项目后，在pom.xml中新增以下依赖<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId></dependency><dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId></dependency>
3、创建实体类定义实体类UserInfo，使用@Entity标识，并声明@Id属性。@Entitypublic class UserInfo implements Serializable{ @Id private Long id; private String userName; private String passWord; /**省略get set 方法*/}
5、创建Service类定义新增，查询数据方法@Servicepublic class UserService { @Autowired private UserDao userDao; public List<User> getUser(String userName) { return userDao.getUserByName(userName); } public int addUserInfo(UserInfo user) { return userDao.addUserInfo(user); }}
7、测试结果执行该测试方法，输出结果为：add user count=1user.id=10000,user.name=user,user.password=pwd
