Spring Boot整合使用JdbcTemplate

创建一个Maven工程。

pom文件引入

    dependencies>

注意: spring-boot-starter-parent要在1.5以上

application.properties新增配置

spring.datasource.url=jdbc:mysql://localhost:3306/springboot
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

UserService类

package com.cc.springboot.service;

public interface UserService {

    public void createJdbcUser();

}

package com.cc.springboot.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Service;

import com.cc.springboot.service.UserService;


@Service
public class UserServiceImpl implements UserService {
    @Autowired
    private JdbcTemplate jdbcTemplate;

    public void createJdbcUser() {
        jdbcTemplate.update("insert into users values(?,?);",1,"kevin cai");
    }

}

Controller类

package com.cc.springboot.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.cc.springboot.service.UserService;


@RestController
public class IndexController {

    @Autowired
    private UserService userService;

    @RequestMapping("/index")
    public String index(){
        userService.createJdbcUser();
        return "add success";
    }

}

app类

package com.cc.springboot.app;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;

@ComponentScan(basePackages = { "com.cc.springboot.controller", "com.cc.springboot.service" })
@EnableAutoConfiguration
public class App {

    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }

}
