SpringBoot整合jdbcTemplate特详细教程
这里主要就是写一下自己是如何使用springboot来做的JdbcTemplate的整合操作的
先说一下自己的环境吧:系统是win10的,jdk1.8(64位),mysql 是Ver 14.14 Distrib 5.5.27, for Win32 (x86)
第一步先创建一个springboot的项目
先来看一下最终的目录结构吧
pom文件

下面是启动类HousesApplication.java
package com.baidu.demo000;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@MapperScan("com.baidu.demo000.mapper")
public class HousesApplication {
public static void main(String[] args) {
SpringApplication.run(HousesApplication.class, args);
}
}然后开始编写配置文件application.yml
server:
port: 9010
spring:
datasource:
url: jdbc:mysql://localhost:3306/db_user
username: root
password: 123456
driver-class-name: com.mysql.jdbc.Driver
type: com.alibaba.druid.pool.DruidDataSource
这里开始在数据库中造数据,数据库的结构如图
造数据
DROP TABLE IF EXISTS `tb_user`;
CREATE TABLE `tb_user` (
`id` int(11) NOT NULL AUTO_INCREMENT COMMENT 'ID',
`username` varchar(50) NOT NULL COMMENT '用户名',
`age` int(11) NOT NULL COMMENT '年龄',
`ctm` datetime NOT NULL COMMENT '创建时间',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=8 DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of tb_user
-- ----------------------------
INSERT INTO `tb_user` VALUES ('1', '张三', '18', '2019-01-24 09:07:41');
INSERT INTO `tb_user` VALUES ('2', '李四', '20', '2019-01-24 09:07:41');
INSERT INTO `tb_user` VALUES ('3', '王五', '19', '2019-01-24 09:07:41');
下面开始创建实体类User.java
package com.baidu.demo000.model;
import java.util.Date;
public class User {
private int id;
private String username;
private int age;
private Date ctm;
public User() {
}
public User(String username, int age) {
this.username = username;
this.age = age;
this.ctm = new Date();
}
// Getter、Setter
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public Date getCtm() {
return ctm;
}
public void setCtm(Date ctm) {
this.ctm = ctm;
}
@Override
public String toString() {
return "User{" +
"id=" + id +
", username='" + username + '\'' +
", age=" + age +
", ctm=" + ctm +
'}';
}
}首先编写的是dao层的代码UserDao.java
package com.baidu.demo000.dao;
import com.baidu.demo000.model.User;
import java.util.List;
public interface UserDao {
User getUserById(Integer id);
public List getUserList();
public int add(User user);
public int update(Integer id, User user);
public int delete(Integer id);
} 然后编写他的实现类UserDaoImpl.java
package com.baidu.demo000.dao.impl;
import com.baidu.demo000.dao.UserDao;
import com.baidu.demo000.model.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.BeanPropertyRowMapper;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Repository;
import java.util.Date;
import java.util.List;
@Repository
public class UserDaoImpl implements UserDao {
@Autowired
private JdbcTemplate jdbcTemplate;
@Override
public User getUserById(Integer id) {
List list = jdbcTemplate.query("select * from tb_user where id = ?", new Object[]{id}, new BeanPropertyRowMapper(User.class));
if(list!=null && list.size()>0){
return list.get(0);
}else{
return null;
}
}
@Override
public List getUserList() {
List list = jdbcTemplate.query("select * from tb_user", new Object[]{}, new BeanPropertyRowMapper(User.class));
if(list!=null && list.size()>0){
return list;
}else{
return null;
}
}
@Override
public int add(User user) {
return jdbcTemplate.update("insert into tb_user(username, age, ctm) values(?, ?, ?)",
user.getUsername(),user.getAge(), new Date());
}
@Override
public int update(Integer id, User user) {
return jdbcTemplate.update("UPDATE tb_user SET username = ? , age = ? WHERE id=?",
user.getUsername(),user.getAge(), id);
}
@Override
public int delete(Integer id) {
return jdbcTemplate.update("DELETE from tb_user where id = ? ",id);
}
} service层的编写 UserService.java
package com.baidu.demo000.service;
import com.baidu.demo000.model.User;
import java.util.List;
public interface UserService {
User getUserById(Integer id);
public List getUserList();
public int add(User user);
public int update(Integer id, User user);
public int delete(Integer id);
} 实现类的编写 UserServiceImpl.java
package com.baidu.demo000.service.impl;
import com.baidu.demo000.dao.UserDao;
import com.baidu.demo000.model.User;
import com.baidu.demo000.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserDao userDao;
@Override
public User getUserById(Integer id) {
return userDao.getUserById(id);
}
@Override
public List getUserList() {
return userDao.getUserList();
}
@Override
public int add(User user) {
return userDao.add(user);
}
@Override
public int update(Integer id, User user) {
return userDao.update(id, user);
}
@Override
public int delete(Integer id) {
return userDao.delete(id);
}
} 最后是表现层
UserController.javapackage com.baidu.demo000.controller;
import com.baidu.demo000.model.User;
import com.baidu.demo000.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import java.util.ArrayList;
import java.util.List;
@RestController
public class UserController {
@Autowired
private UserService userService;
/**
* 根据ID查询用户
* @param id
* @return
*/
@RequestMapping(value = "user/{id}", method = RequestMethod.GET)
public User getUserById (@PathVariable(value = "id") Integer id){
User user = new User();
try {
user = userService.getUserById(id);
} catch (Exception e) {
e.printStackTrace();
}
return user;
}
/**
* 查询用户列表
* @return
*/
@RequestMapping(value = "users", method = RequestMethod.GET)
public List getUserList (){
List users = new ArrayList<>();
try {
users = userService.getUserList();
} catch (Exception e) {
e.printStackTrace();
}
return users;
}
/**
* 添加用户
* @param user
* @return
*/
@RequestMapping(value = "user", method = RequestMethod.POST)
public String add (@RequestBody User user){
int orderId = 0;
try {
//添加操作返回的是受影响的行数
orderId = userService.add(user);
if(orderId==0){
//添加失败
return "添加失败";
}else{
return "添加成功";
}
} catch (Exception e) {
e.printStackTrace();
return "添加失败";
}
}
/**
* 根据id删除用户
* @param id
* @return
*/
@RequestMapping(value = "user/{id}", method = RequestMethod.DELETE)
public String delete (@PathVariable(value = "id") Integer id){
try {
int ret =0;
ret = userService.delete(id);
if (ret <= 0) {
return "删除失败";
} else {
return "删除成功";
}
} catch (Exception e) {
e.printStackTrace();
return "删除失败";
}
}
/**
* 根据id修改用户信息
* @param user
* @return
*/
@RequestMapping(value = "user/{id}", method = RequestMethod.PUT)
public String update (@PathVariable("id") Integer id, @RequestBody User user){
try {
int ret = 0;
ret = userService.update(id, user);
if (ret <= 0) {
return "修改失败";
} else {
return "修改成功";
}
} catch (Exception e) {
e.printStackTrace();
return "修改失败";
}
}
} 下面开始测试,首先开启启动类

控制台正常开启
下面通过Postman来做测试
第一步查询全部的操作,请求方式选择get请求,因为controller.java中对应的方法上做了请求方式的限定,下面每一个方法的请求方式都是不一样的请注意!!!!!!!
第二步添加操作,选择post的请求方式,因为在congtroller中的添加方法上做了请求方式的限定!!!
返回的结果是
重新查询全部
接着是修改操作(先看自己数据库中有哪些数据)
