springboot整合mysql存储过程

以下是在Spring Boot中整合MySQL存储过程的步骤：

1.在pom.xml文件中添加MySQL驱动程序的依赖项：

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>

2.在application.properties文件中配置MySQL数据库连接信息：

spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

3.创建一个存储过程：

DELIMITER $$
CREATE PROCEDURE `get_user`(IN id INT, OUT name VARCHAR(20))
BEGIN
    SELECT user_name INTO name FROM user WHERE user_id = id;
END$$
DELIMITER ;

4.创建一个DAO类来调用存储过程：

@Repository
public class UserDao {
    @Autowired
    private JdbcTemplate jdbcTemplate;

    public String getUser(int id) {
        SimpleJdbcCall jdbcCall = new SimpleJdbcCall(jdbcTemplate)
                .withProcedureName("get_user");
        SqlParameterSource in = new MapSqlParameterSource().addValue("id", id);
        Map<String, Object> out = jdbcCall.execute(in);
        return (String) out.get("name");
    }
}

5.在控制器中使用DAO类来调用存储过程：

@RestController
public class UserController {
    @Autowired
    private UserDao userDao;

    @GetMapping("/user/{id}")
    public String getUser(@PathVariable int id) {
        return userDao.getUser(id);
    }
}
