java - 如何将设置 Spring Boot 的主要方法移动到基础包中而不破坏它

Question

我正在查看 Spring Boot，给我留下了深刻的印象。发展非常快。我有一个应用程序，但是，所有示例都有 Controller 包中的 main 方法。 [例如。 com.demo] 我想将 Controller 移动到它自己的包中。 [例如。 com.demo.controller]。然后将main方法留在基础包[com.demo]中。当我这样做的时候，世界就被打破了。似乎某些注释可能需要分离出来，或者便捷方法可能需要分解。我已将我的 Application.java 移至基础包中，正如我在上面所述，并移动了我认为正确的注释，但似乎我遗漏了一些东西。这是我的代码。

package com.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import com.demo.controllers.StudentController;

@SpringBootApplication
@EnableAutoConfiguration
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(StudentController.class, args);
    }
}

我的 Controller 如下

package com.demo.controllers;

import java.util.ArrayList;
import java.util.List;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import com.demo.models.Student;

@Controller
@RequestMapping("/student")
public class StudentController {

    @RequestMapping(method = RequestMethod.GET)
    public List<Student> getAll() {
        return new ArrayList<Student>();
    }

    @RequestMapping(method = RequestMethod.POST)
    public Student create(@RequestBody Student Student) {
        return null;
    }

    @RequestMapping(method = RequestMethod.DELETE, value = "{id}")
    public void delete(@PathVariable String id) {

    }

    @RequestMapping(method = RequestMethod.PUT, value = "{id}")
    public Student update(@PathVariable String id, @RequestBody Student Student) {
        return null;
    }
}

我得到的堆栈跟踪是这样的。

不确定我是否缺少注释或需要拆分一些方便注释。

Answer 1

它不是 SpringApplication.run(StudentController.class, args); 而是 SpringApplication.run(Application.class, args);。

仔细遵循指南。
