java - springboot api 不工作。

Question

这是一个简单的代码，但我缺少一些我没有得到的东西，应用程序正在运行，但 API 无法工作。运行代码时，它不会记录公开的 api 详细信息。调试时使用 RequestMappingHandlerMapping 不会调试映射的 api。你能帮我解决这个问题

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

是组件扫描基础包造成的。 should refer best practice of spring boot package layout它说，

We generally recommend that you locate your main application class in a root package above other classes. The @SpringBootApplication annotation is often placed on your main class, and it implicitly defines a base “search package” for certain items.

这意味着如果您想将 com.mindtree.mydemo1 定义为基础包，您应该将 Controller 包移至 com.mindtree.mydemo1.controllers
