springboot+springmvc+mybatis+idea整合
用springboot+springmvc+mybatis+idea整合
首先我的教程非常详细安照流出配置即可本教程适合idea的maven 环境完全搭好的环境
第一步创建一个maven工程
新的改变
1.不用勾选Create from archetype
2.点击new
3.编写项目名
4.点击new
5.点击Finish
6.项目目录
2. **全新的配置设计
**1.新建文件夹
2.建好所有文件夹和文件
pom.xml配置

所有文件配置
1.DmoController类
package cn.tx.controller;
import cn.tx.domain.Demo;
import cn.tx.service.DemoService;
import cn.tx.service.DemoServiceM;
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.RestController;
import java.util.List;
@Controller
@RequestMapping("/demo")
public class DmoController {
@Autowired
private DemoServiceM demoService;
@RequestMapping("/findAll")
public List<Demo> findAll(){
return demoService.findAll();
}
@RequestMapping("/login")
public String login(){
return "/login";
}
@RequestMapping("/logins")
public String logins(String name){
System.out.println(name+"------------------------------------");
Demo demo=demoService.findAllLogin(name);
if(demo !=null){
return "/index";
}else{
return "/login";
}
}
}
2.DemoMapper类
package cn.tx.dao;
import cn.tx.domain.Demo;
import org.apache.ibatis.annotations.Mapper;
import java.util.List;
@Mapper//可以扫描mapper
public interface DemoMapper {
public List<Demo> findAll();
public Demo findAllLogin(String name);
}
3.Demo实体类
package cn.tx.domain;
public class Demo {
private int id;
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
}
4.DemoService类
package cn.tx.service;
import cn.tx.domain.Demo;
import java.util.List;
public interface DemoService {
public List<Demo> findAll();
public Demo findAllLogin(String name);
}
5.DemoServiceM类
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import javax.annotation.Resource;
import java.util.List;
@Service
@Transactional//事物的注解
public class DemoServiceM implements DemoService {
@Resource
private DemoMapper demoMapper;
@Override
public List<Demo> findAll() {
return demoMapper.findAll();
}
@Override
public Demo findAllLogin(String name) {
return demoMapper.findAllLogin(name);
}
6.DemoApplication类
package cn.tx;
import cn.tx.domain.Demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class DemoApplication {
public static void main(String[] arg){
SpringApplication.run(DemoApplication.class,arg);
}
}
7.UserMapper.xmlSQL配置

11.application.yml核心配置一般springboot自动帮你配置了但是数据库无法配置springboot共有3种配置文件类型可配置
核心的配置yml只是其中一种而已但是yml可读性强
spring:
datasource:
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:3306/stum
username: root
passwrod:
mybatis:
mapper-locations: classpath:mappers/*.xml
type-aliases-package: cn.tx.domain
server:
port: 8888
需要注意的事情
1.http://localhost:8888/demo/login我的访问路径供参考
2.jdk最后1.7以上idea的11也可以反正我这没问题
