springboot+mybatsi-plus+lombok+swagger-bootstra整合

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>>

版本要求：jdk1.8以上

框架版本介绍：springboot 2.x

mybatis-plus 3.x

Maven 3.x以上

辅助工具介绍：lombok 简化代码

Swagger-bootstrap-ui 生成接口文档

Yml文件

注意：1、springboot1.x与2.x版本改动较大，具体请阅看官方文档。

官方地址：https://spring.io/projects/spring-boot/

2、mybatis-plus 3.x与2.x 版本改动较大，具体请查阅官方文档。

官网地址：https://mp.baomidou.com/

解释说明：

springboot优点在于简化配置，全家桶自动集成优秀框架，基于注解开发。

综上所有优点，我们选择了lombok,与mybatis-plus ，还有swagger-ui。这三个都是基于注解使用。我认为选择其他的感觉优点鸡肋。

目录结构：

app启动类内容：

import org.mybatis.spring.annotation.MapperScan;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;



@SpringBootApplication

@MapperScan("com.siyuan.user.mapper")

public class App {

public static void main(String[] args) {

SpringApplication.run(App.class, args);

}

}

loginController控制层类容：


import java.util.List;



import javax.annotation.Resource;



import org.springframework.web.bind.annotation.GetMapping;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

}

@GetMapping("/demo01")

@ApiOperation(value = "demo测试2", tags = {"返回用户信息"}, notes = "务必提交json格式")

public String demo01(){

List<User> list = userMapper.selectList(null);

return list.toString();

}

@GetMapping("/demo02")

@ApiOperation(value = "demo测试3", tags = {"返回用户信息"}, notes = "务必提交json格式")

public String demo02(){

int list = userMapper.findOne();

return list+"";

}

}

mapper dao层接口内容：

public interface UserMapper extends BaseMapper<User> {

public int findOne();

}

xml内容：

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

<mapper namespace="com.siyuan.user.mapper.UserMapper">

<select id="findOne" resultType="int">

select 1 from dual

</select>

</mapper>

model层内容：

import com.baomidou.mybatisplus.annotation.TableField;

import com.baomidou.mybatisplus.annotation.TableName;



import lombok.Data;



@Data

@TableName("表明")

public class User {

@TableField("字段名称")

private String name;

}

swagger-ui内容：


import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;

import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

//添加ResourceHandler

@Override

public void addResourceHandlers(ResourceHandlerRegistry registry) {

registry.addResourceHandler("/**").addResourceLocations("classpath:/static/");

registry.addResourceHandler("swagger-ui.html")

.addResourceLocations("classpath:/META-INF/resources/");
