【问题描述】：
我正在尝试运行一个 Spring Boot 项目。当我选择 1.5.2 版时，requestMapping url 不起作用。它总是给我404错误。
如果缺少任何标签或版本中的任何设置更改，有人可以确认我。或任何其他我错过的东西。

控制器：
package com.prizy.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
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 org.springframework.web.bind.annotation.RestController;
import com.prizy.model.Product;
import com.prizy.service.ProductService;
@RestController
public class ProductController {
@Autowired
private ProductService productService;
@RequestMapping("/products")
public List<Product> getAllProducts() {
return productService.getAllProducts();
}
@RequestMapping("/hi")
public String getString() {
return "Hi";
}
@RequestMapping("/products/{productId}")
public Product getProduct(@PathVariable int productId){
return productService.getTopic(productId);
}
@RequestMapping(method=RequestMethod.POST, value="/products")
public void addProduct(@RequestBody Product product) {
productService.addProduct(product);
}
@RequestMapping(method=RequestMethod.PUT, value="/products/{productId}")
public void updateProduct(@RequestBody Product product, @PathVariable int productId) {
productService.updateProduct(product,productId);
}
@RequestMapping(method=RequestMethod.DELETE, value="/products/{productId}")
public void deleteProduct(@PathVariable int productId) {
productService.deleteProduct(productId);
}
}
主类是
package com.prizy;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@EnableAutoConfiguration
@SpringBootApplication
public class ProductApiApplication {
public static void main(String[] args) {
SpringApplication.run(ProductApiApplication.class, args);
}
}
注意：问题已更新，包含更多信息。
【问题讨论】：
-
您要访问的网址是什么？
-
package com.prizy.controller: 你的主班在哪里？ -
你能把你的主类和包名一起发布吗？
-
这个类的其他方法有用吗？不应该使用
get...方法名称吗？您是否尝试过更改方法的名称或将/hi定位到另一个方法？
