我是 Java 新手，第一次使用 Eclipse 和 IntelliJ。 我正在尝试从 Spring Boot 应用程序对 https://catfact.ninja/fact 进行 REST 调用。当我从 IntelliJ 运行它时它可以工作，但相同的代码在从 Eclipse 运行时抛出异常。我想我在 Eclipse 中遗漏了一些设置，但找不到什么。任何帮助将不胜感激！
无法找到到请求目标的有效认证路径] 具有根本原因
我厌倦了不同的端点 http://jsonplaceholder.typicode.com/todos 并且它有效。
我的代码：
配置
package com.random.restClientTest.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;
@Configuration
public class AppConfig {
@Bean
public RestTemplate restTemplate() {
return new RestTemplate();
}
}
控制器
package com.random.restClientTest.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.random.restClientTest.service.ServiceLayer;
@RestController
@RequestMapping("/")
public class HomeController {
private final ServiceLayer serviceLayer;
@Autowired
public HomeController(ServiceLayer serviceLayer) {
this.serviceLayer = serviceLayer;
}
@GetMapping("/typicode")
public String getData() {
return serviceLayer.consumeAPI();
}
}
服务
package com.random.restClientTest.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.web.client.RestTemplate;
@Service
public class ServiceLayer {
private final RestTemplate restTemplate;
@Autowired
public ServiceLayer(RestTemplate restTemplate) {
this.restTemplate = restTemplate;
}
public String consumeAPI() {
return restTemplate.getForObject("https://catfact.ninja/fact", String.class);
//return restTemplate.getForObject("http://jsonplaceholder.typicode.com/todos", String.class);
}
}
错误
