SpringBoot整合ssm框架使用

SpringBoot环境搭建

见之前博客内容：SpringBoot环境搭建

SpringBoot整合MyBatis

工程结构目录图

pom文件中导入相关依赖

配置application.yml

spring:
  datasource:
     url: jdbc:mysql://127.0.0.1:3306/testdemo?useUnicode=true&characterEncoding=utf8
     username: root
     password: root
     driver-class-name: com.mysql.jdbc.Driver

创建相应数据库以及数据库表

创建pojo实体对象，使用lombok插件生成getset方法

package com.ljctest.pojo;

import lombok.Getter;
import lombok.Setter;

@Getter
@Setter
public class User {

    private Integer id;
    private String username;
    private String password;
}

编写dao接口

package com.ljctest.dao;

import com.ljctest.pojo.User;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;

import java.util.List;
@Mapper
public interface HelloDao {

    @Select("select * from user")
    ListfindAll();
}

编写controller、service

package com.ljctest.service;

import com.ljctest.dao.HelloDao;
import com.ljctest.pojo.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class HelloService {

    @Autowired
    HelloDao dao;


    public List findAll(){
        return  dao.findAll();
    }



}

package com.ljctest.controller;

import com.ljctest.pojo.User;
import com.ljctest.service.HelloService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController
@RequestMapping("hello")
public class HelloController {

    @Autowired
    HelloService service;

    @RequestMapping("testOne")
    public String testOne(){

        return "success";
    }

    @RequestMapping("findAll")
    public ListfindAll(){
        return service.findAll();
    }


}

使用了阿里的json解析相关依赖。

编写引导类，启动测试。

package com.ljctest;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * 引导类
 */
@SpringBootApplication
public class ApplicationTest {

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

 

测试成功！
