整合过程介绍（开发工具：IntelliJ IDEA ）
项目结构如下：
1、新建springboot maven项目，pom.xml配置如下：
4.0.0 com.xieke.test springbootmybatisdemo 0.0.1-SNAPSHOT jar springbootmybatisdemo Demo project for Spring Boot Mybatis org.springframework.boot spring-boot-starter-parent 2.0.2.RELEASE UTF-8 UTF-8 1.8 org.springframework.boot spring-boot-starter-web org.mybatis.spring.boot mybatis-spring-boot-starter 1.3.2 mysql mysql-connector-java runtime org.springframework.boot spring-boot-starter-test test org.springframework.boot spring-boot-maven-plugin
2、添加application.properties文件到 resources下，配置如下：
server:
port: 1314
#配置数据源
spring:
datasource:
url: jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf8
username: root
password: 999999
driver-class-name: com.mysql.jdbc.Driver
#指定mybatis映射文件的地址
mybatis:
mapper-locations: classpath:mapper/*.xml
# 打印sql
logging:
level:
com.xieke.test.dao : debug
3、SQL初始化文件table.sql，内容如下：
use test;
drop table `user`;
create table `user` (
`id` int(10) NOT NULL AUTO_INCREMENT,
`name` varchar(25) NOT NULL,
`password` varchar(25) NOT NULL,
PRIMARY KEY (`id`)
);
insert into `user` (`id`, `name`, `password`) values('1','xieke','999999');
insert into `user` (`id`, `name`, `password`) values('2','43434','324233');
insert into `user` (`id`, `name`, `password`) values('3','34344','343434');
4、控制层、业务层、持久层、实体类代码如下：
package com.xieke.test.controller;
import com.xieke.test.entity.User;
import com.xieke.test.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
@RequestMapping(value = "/user")
public class UserController {
@Autowired
private UserService userService;
@RequestMapping(value = "/show")
@ResponseBody
public String show(@RequestParam(value = "name")String name){
User user = userService.findUserByName(name);
if(null != user)
return user.getId()+"/"+user.getName()+"/"+user.getPassword();
else
return "null";
}
@RequestMapping(value = "/show2")
@ResponseBody
public String show2(@RequestParam(value = "name")String name, @RequestParam(value = "password")String password){
User user = userService.findUserByNameAndPassword(name, password);
if(null != user)
return user.getId()+"/"+user.getName()+"/"+user.getPassword();
else
return "null";
}
@RequestMapping(value = "/add")
@ResponseBody
public String add(){
userService.saveUser();
User user = userService.findUserByName("a123456789");
if(null != user)
return user.getId()+"/"+user.getName()+"/"+user.getPassword();
else
return "null";
}
}
package com.xieke.test.service;
import com.xieke.test.dao.UserDao;
import com.xieke.test.entity.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
@Service
public class UserService {
@Autowired
private UserDao userDao;
public User findUserByName(String name){
User user = null;
try{
user = userDao.findUserByName(name);
} catch (Exception e){
}
return user;
}
public User findUserByNameAndPassword(String name, String password){
User user = null;
try{
User u = new User();
u.setName(name);
u.setPassword(password);
user = userDao.findUserByNameAndPassword(u);
} catch (Exception e){
}
return user;
}
@Transactional
public void saveUser ( ){
userDao.insertUser("a123456789", "123456789");
// int n = 1/0;
// userDao.insertUser("b123456789", "123456789");
}
}
package com.xieke.test.dao;
import com.xieke.test.entity.User;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
@Mapper
public interface UserDao {
@Select("SELECT * FROM user WHERE name = #{name}")
User findUserByName(@Param("name") String name);
@Insert("INSERT INTO user(name, password) VALUES(#{name}, #{password})")
int insertUser(@Param("name") String name, @Param("password") String password);
User findUserByNameAndPassword (User user);
}
package com.xieke.test.entity;
public class User {
private long id;
private String name;
private String password;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
5、启动类代码如下，启动后访问localhost:1314/user/show?name=xieke测试，详细代码请参考码云。
package com.xieke.test;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.transaction.annotation.EnableTransactionManagement;
@SpringBootApplication
@EnableTransactionManagement
public class SpringbootmybatisdemoApplication {
public static void main(String[] args) {
SpringApplication.run(SpringbootmybatisdemoApplication.class, args);
}
}
