使用JdbcTemplate操作数据库中的数据

Posted 2023-02-20 @carefree

package com.example.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

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

@RestController
public class JdbcController 

    @Autowired          //自动配置，因此可以直接通过@Autowired注入进来
    private JdbcTemplate jdbcTemplate;

    @GetMapping("/users/queryAll")
    public List<Map<String,Object>> queryAll()
        List<Map<String,Object>> list = jdbcTemplate.queryForList("select * from tb_user");
        return list;
    
    
    @GetMapping("/users/insert")
    public Object insert(String name,String password)
        jdbcTemplate.execute("insert into tb_user(`name`,`password`) value (\\""+name+"\\",\\""+password+"\\")");
        return true;
