Question

它是一个简单的代码，但是我缺少一些我没有得到的东西，该应用程序正在运行，但API无法正常工作。在运行代码时，它不会记录公开的api详细信息。在调试时使用RequestMappingHandlerMapping不能调试映射的api。你能帮我吗

Controller.java：

package com.mindtree.controllers;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class Controller {

@RequestMapping("/find")
    @ResponseBody
    public ResponseEntity<String> findEmployee(){
        String emp;
        emp="id is: ";
        return new ResponseEntity<String>(emp,HttpStatus.OK);
    }
}

Answer 1

它是由组件扫描的基本程序包引起的。 should refer best practice of spring boot package layout 它说，

我们通常建议您将主应用程序类放在其他类之上的根包中。 @SpringBootApplication批注通常放在您的主类上，它隐式定义某些项目的基本“搜索包”。

这意味着如果要将com.mindtree.mydemo1.controllers定义为基本软件包，应将控制器软件包移至com.mindtree.mydemo1

springboot api不起作用。
