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 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 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 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 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

    
         select * from demo;
    
    
        select*from demo where  name=#{name}
    

8.index.html

    
    


登录成功

9.login.html

    
    


 

     


         

             
姓名：
             

         

         

             

         
     
 

10.success.html

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
