Я полностью новичок в Spring (вы можете видеть это в моем коде:)). Я просто хотел протестировать класс RestTemplate, но я получил ClassNotFoundException
.
Таким образом, код:
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.web.client.RestTemplate;
public class RestClient {
private RestTemplate restTemplate;
public String getJiraIssueAsJson(){
Object o = restTemplate.getForObject(..., Object.class);
System.out.println("..."+o.getClass());
return null;
}
public void setRestTemplate(RestTemplate restTemplate) {
this.restTemplate = restTemplate;
}
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("rest-client-context.xml");
RestClient restClient = context.getBean("restClient", RestClient.class);
restClient.getJiraIssueAsJson();
}
}
context.xml

У меня есть это исключение, когда я пытаюсь запустить основной метод из eclipse.
Я могу думать о чем-то вроде Spring банки не видно, но я не знаю, почему...
Можете ли вы мне помочь?
