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. 编写测试类

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;

/**

• @author liwen406
• @Title: HelloControler
• @Description:

• @date 2018/12/21 / 22:27br/>*/
  @Controller
  public class HelloControler {

  @Autowired
  JdbcTemplate jdbcTemplate;

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

}
