    1. 配置

    spring:
    datasource:
    username: root
    password: 123123
    url: jdbc:mysql://47.114.216.342:3306/zlgc?useUnicode=true&characterEncoding=UTF-8&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC&useSSL=false
    type: com.alibaba.druid.pool.DruidDataSource

    schema:

    • classpath:department.sql
    
    1. 編寫測試類
    

    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.autoconfigure.data.redis.RedisProperties;
    import org.springframework.jdbc.core.JdbcTemplate;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.PutMapping;

    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;

    import java.util.List;
    import java.util.Map;

    /**

      @Controller
      br/>*/
      @Controller

      @Autowired
      JdbcTemplate jdbcTemplate;

      @ResponseBody@RequestMapping("/quary")
      br/>@RequestMapping("/quary")
      List<Map<String,Object>> list = jdbcTemplate.queryForList("select * from user; ");
      return list.get(0);
      }

    }

    
    結果:
