Java 如何解决web服务引发的异常？

我在从一个简单的Java客户端调用web服务时遇到了一个问题；我想要你所有的答案

以下是客户端抛出的异常：

Exception in thread "main" java.io.IOException: Server returned HTTP response code: 500 for URL: http://localhost:1010/helloworld
    at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source)
    at org.warnier.zhang.demo.Tests.main(Tests.java:40)

以下是服务器抛出的异常：

Web服务关闭了连接。检查该Web服务的日志，看看发生了什么。一些上下文/代码可能会有用。你只是想访问它，还是在向它发出POST/GET请求等？这里解释Http响应代码500。其原因通常在您的Web服务器日志中
