Knife4j快速整合Springboot

案例背景

Swagger2不好用,使用knife4j,网上的案例又太老旧了,又要引入这个又要配置那个,

最后直接扒取官网,

出现了如下案例代码

import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

@RequestMapping("用户管理API")
@RestController
public class UserController {

    @Autowired
    private RestTemplate restTemplate;

    @ApiOperation("普通body请求")
    @PostMapping("/add")
    public String add() {

        ResponseEntity<String> forEntity = restTemplate.getForEntity("https://www.baidu.com/", String.class);
        return "new User()";
    }
}
