java.lang.VerifyError：尝试运行JDK提供的HttpServer时操作数堆栈上的错误类型

Question

我试图通过模拟HttpServer来进行一些单元测试。 当我运行此代码时，它给了我错误： -

@RunWith(PowerMockRunner.class)
@PowerMockIgnore({"javax.net.ssl.*", "javax.management.*"})

public class POSTServerTest {
private String endPoint = "http://localhost:30310/api/endpoint/";
private String connectionTimeOut = "3000";
private String readTimeOut = "3000";

private HttpServer server;

@Captor
ArgumentCaptor<Logger> loggerArgumentCaptor;

@Captor
ArgumentCaptor<String> stringArgumentCaptor;

@Before
public void setUp() throws IOException {
    MockitoAnnotations.initMocks(this);
    server = HttpServer.create(new InetSocketAddress(8080), 0);
    server.start();

}

@Test
public void testReadTimeOutException() throws Exception {
    setConnectionTimeOut("3000");
    setReadTimeOut("1");
    //some code here 
}
}

我得到这个错误： -

我正在尝试用maven构建它，这里是它使用的java版本的maven输出： -

任何人都可以帮助我运行这个HttpServer示例代码吗？ 任何帮助你真的很感激。 :)

Answer 1

@PowerMockIgnore({"sun.net.*", "com.sun.*"})
public class POSTServerTest {...

问题出在PowerMock上。 添加要忽略的其他类将通过阻止这些类的字节代码验证来实现。

Answer 2

@PowerMockIgnore（“sun.net.httpserver。 ”，“com.sun.net.httpserver ”）公共类POSTServerTest {...
