7、SpringBoot 整合JDBC使用

1、添加所需要的依赖包

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jdbc</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

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

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

 

2、配置SringBoot配置文件application.yml

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://8.129.215.115:3306/mybatis_plus?useUnicode=true&characterEncoding=utf-8&useSSL=false
    username: root
    password: 123456

3、编写Controller测试Jdbc

@RestController
public class JdbcController {
    @Autowired
    JdbcTemplate jdbcTemplate;

    @GetMapping(value = "/query")
    public List<Map<String,Object>> list (){
        String sql = "select *from book";
        List<Map<String, Object>> maps = jdbcTemplate.queryForList(sql);
        return maps;
    }
}
