Spring REST端点：404请求的资源不可用错误

Question

我使用 Rest 应用程序创建了 Spring Boot 入门项目。当尝试运行应用程序时 在服务器上运行，它将使用 URL 重定向到 Web 浏览器，直到上下文路径，但在添加端点和 执行它会抛出资源不可用错误。我尝试了很多但没有任何帮助。请帮我解决这个问题。

控制器类：

package in.ineuron.controller;

import java.time.LocalDateTime;

import org.springframework.http.HttpStatus;    
import org.springframework.http.HttpStatusCode;    
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import in.ineuron.response.CurrencyResponse;

@RestController
@RequestMapping("/api/currency")
public class CurrencyController {

@GetMapping("/getCurrencyValue/from/{from}/to/{to}")
public ResponseEntity<CurrencyResponse> getCurrencyValue(@PathVariable String from,
        @PathVariable String to){
    CurrencyResponse response=new CurrencyResponse();
    response.setCurrencyId(1);
    response.setCurrencyFrom(from);
    response.setCurrencyTo(to);
    response.setCurrencyValue(82);
    return new ResponseEntity<CurrencyResponse>(response, HttpStatus.OK);   
}

@GetMapping("/wish")
public ResponseEntity<String> wishMessage(){
    LocalDateTime ldt=LocalDateTime.now();
    int hour=ldt.getHour();
    String body=null;
    if(hour<12)
        body="Good Morning";
    else if(hour<16)
        body="Good Noon";
    else if(hour<20)
        body="Good evening";
    else
        body="Good Night";
    return new ResponseEntity<String>(body, HttpStatus.OK);
    
}

}

URL 端点：

1. http://localhost:8081/1.SpringRest-WebclientProducerApp/api/currency/getCurrencyValue/from/USD/to/INR

2. http://localhost:8081/1.SpringRest-WebclientProducerApp/api/currency/wish

面临 HTTP 状态 404 – 未找到错误。请求的资源[/1.SpringRest-WebclientProducerApp/api/currency/wish]不可用

请采取必要措施来解决此案。

Answer 1

您认为为什么 URL 必须包含这一部分？

1.SpringRest-WebclientProducerApp

试试这个

http://localhost:8081/api/currency/wish
