我正在开发一个包含用户、产品、插件(浇头)等的全栈应用程序。
然而，当我尝试运行localhost:8080/Admin/users/Sean(示例)时，它应该提升用户。然而，它只是给了我上面的错误。"得不到支持"。尽管我使用的是putmapping，而不是getmapping，但还是发生了这种情况。下面是提供的代码:
AdminController.java
package com.example.pizza_order_service.controllers;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.example.pizza_order_service.model.Addon;
import com.example.pizza_order_service.model.Product;
import com.example.pizza_order_service.model.User;
import com.example.pizza_order_service.service.AddonService;
import com.example.pizza_order_service.service.ProductService;
import com.example.pizza_order_service.service.UserService;
@Controller
@RequestMapping("/Admin")
public class AdminController {
@Autowired
private ProductService prodService;
@Autowired
private UserService userService;
@Autowired
private AddonService addonService;
@GetMapping("")
public ModelAndView listProducts() {
List<Product> products = prodService.findAll();
return new ModelAndView("product","Product", products);
}
@GetMapping("/")
public ModelAndView listAddons() {
List<Addon> addons = addonService.findAll();
return new ModelAndView("product","Addon", addons);
}
@GetMapping("/Product")
public String displayProducts(ModelMap model) {
Iterable<Product> results = prodService.findAll();
model.addAttribute("product", results);
return "product";
}
@GetMapping("/Toppings")
public String displayToppings(ModelMap model) {
Iterable<Addon> results = addonService.findAll();
model.addAttribute("toppings", results);
return "Addon";
}
// - Promote Users
@PutMapping("/users/{id}")
public String promoteUser(User newUser){
User user = userService.findUserByUserName(newUser.getName());
user.setRole(newUser.getRole());
return "Promotion confirmed";
}
//- Delete Product
@DeleteMapping(value="/deleteProd/{id}")
public ModelAndView deleteAProduct(@PathVariable("id") long id) {
prodService.deleteProduct(id);
return listProducts();
}
//- Delete Toppings
@DeleteMapping(value="/deleteAddon/{id}")
public ModelAndView deleteAnAddon(@PathVariable("id") long id) {
addonService.deleteAddon(id);
return listAddons();
}
}
users.html
<!-- HTML -->
<html id="content">
<head>
<div th:replace="fragment.html :: header"></div>
<!-- CSS -->
<style>
td {
padding: 10px;
}
</style>
<!-- End CSS -->
</head>
<body class="background" style="overflow: hidden;">
<!-- Navbar -->
<div th:replace="fragment.html :: navbar"></div>
<!-- Menu -->
<br><br><br><br><br><br><br>
<table class="xy-center" style="position: fixed; background-color: var(--tertiary); color: var(--primary); font-size: 3.5vh; border-radius: 15px; padding: 5px;">
<b th:utext="${user}"></b>
</table>
<!-- End Menu -->
<p>
<br>
<br>
<br><br><br><br><br><br>
Hello World!</p>
</body>
<!-- JS -->
<script>
// To open the navbar buttons
$(document).ready(function() {
$('.first-button').on('click', function () {
$('.animated-icon1').toggleClass('open');
});
});
</script>
<!-- End JS -->
</html>
如果需要更多的代码请让我知道，这是一个相当大的应用程序。谢谢你。
编辑:顺便说一下，当我试图调用deletemapping时，我也会得到同样的错误。
如果你只输入地址作为url，浏览器不会运行PUT命令。您需要使用HTTP客户端，如cURL或Postman
我认为你应该在你的路径意义前尝试/api/v1/localhost:8080/Admin/users/Sean变成localhost:8080/api/v1/Admin/users/Sean。你能试试吗?
您的请求将无法得到响应
@PutMapping("/users/{id}")
，因为它只接受put。
您需要另一个端点来返回html页面(通过浏览器GET请求)，如
@GetMapping("/users/{id}")
public ModelAndView showUserPage(User user){
return new ModelAndView("users","User", user);
}
