1. 添加依赖

             
                 
      
       io.springfox
                  
      
       springfox-swagger2
                  
      
       2.2.2
              
             
                 
      
       io.springfox
                  
      
       springfox-swagger-ui
                  
      
       2.2.2
              
     

2. 启动swagger ui注解

@SpringBootApplication@EnableSwagger2public class Main {    public static void main(String[] args) throws Exception {        SpringApplication.run(Main.class, args);    }}

3.添加 controller注解

@RestController@RequestMapping("/user")@Api("swagger ui 注释 api 级别")public class HelloWorldController {    @ApiOperation("swagger ui 注释 方法级别")    @RequestMapping(value="/hello",method=RequestMethod.GET)    public  String hello() {        String data = "Never trouble untill trouble troubles you. Some one told me some years ago.";        return data;    }}

4. swagger ui 链接： localhost:8080//swagger-ui.html （默认）
