出現意外錯誤（類型=不允許的方法，狀態=405）。 spring 引導不支持請求方法“GET”

Question

我正在嘗試使用 Spring 引導、reactjs 和 Z38C3787939C7B28B8FCE7DCE7D7D7D7D1D07A33Z 和 Spring 創建刪除 function。 第一步，我只是通過直接輸入 URL 來確認是否激活了刪除操作。 但是即使我直接輸入 URL 也不起作用。 我知道 GET 不受支持，但我不知道應該修復哪個。 如果你知道，請告訴我。

動作控制器.java

package com.example.demo.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.example.demo.repository.CheckListRepository;
import com.example.demo.service.CheckListService;

@CrossOrigin
@RequestMapping("action/")
@RestController
public class ActionController {

    @Autowired
    CheckListRepository clr;

    @Autowired
    CheckListService cls;

    @DeleteMapping(path = "{deleteId}")
    public void deleteAction(@PathVariable Integer deleteId) {

        clr.deletebyListNo(deleteId);

    }

}

PS：這是關於內容的 axios 代碼。 Controller

package com.example.demo.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.example.demo.entity.CheckList;
import com.example.demo.entity.CheckListForm;
import com.example.demo.repository.CheckListRepository;
import com.example.demo.service.CheckListService;

@CrossOrigin
@RestController
@RequestMapping("api/")
public class CheckListController {

    @Autowired
    private CheckListRepository checkListRepository;

    @Autowired
    private CheckListService cls;

    @GetMapping("list")
    public List<CheckListForm> getList() {

        List<CheckList> checkList = this.checkListRepository.findAll();

        List<CheckListForm> checkListForm = cls.entityToForm(checkList);

        return checkListForm;

    }

}

CheckList.js

import axios from 'axios'

const CHECKLIST_REST_API_URL = 'http://localhost:8080/api/list';

class CheckListService {

    getList() {
        return axios.get(CHECKLIST_REST_API_URL);
    }
}


export default new CheckListService();

Answer 1

我可以通過以下方式確認控件中的刪除操作方法已激活。 我改變了代碼

package com.example.demo.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.example.demo.repository.CheckListRepository;
import com.example.demo.service.CheckListService;

@CrossOrigin
@RequestMapping("action/")
@RestController
public class ActionController {

    @Autowired
    CheckListRepository clr;

    @Autowired
    CheckListService cls;

    @DeleteMapping(path = "{deleteId}")
    public void deleteAction(@PathVariable Integer deleteId) {

        clr.deletebyListNo(deleteId);

    }

}

至

package com.example.demo.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.example.demo.repository.CheckListRepository;
import com.example.demo.service.CheckListService;

@CrossOrigin
@RequestMapping("action/")
@RestController
public class ActionController {

    @Autowired
    CheckListRepository clr;

    @Autowired
    CheckListService cls;

    @RequestMapping(path = "{deleteId}")
    public void deleteAction(@PathVariable Integer deleteId) {

        clr.deletebyListNo(deleteId);

    }

}
