出现此问题主要原因是因为在请求过程中证书的问题；有些客户端并未安装服务器要求的证书，所以会产生此问题，以下是部分报错代码：
javax.net.ssl.SSLPeerUnverifiedException: peer not authenticatedat com.sun.net.ssl.internal.ssl.SSLSessionImpl.getPeerCertificates(Unknown Source)at org.apache.http.conn.ssl.AbstractVerifier.verify(AbstractVerifier.java:128)at org.apache.http.conn.ssl.SSLSocketFactory.connectSocket(SSLSocketFactory.java:397)at org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:148)at org.apache.http.impl.conn.AbstractPoolEntry.open(AbstractPoolEntry.java:149)at org.apache.http.impl.conn.AbstractPooledConnAdapter.open(AbstractPooledConnAdapter.java:121)at org.apache.http.impl.client.DefaultRequestDirector.tryConnect(DefaultRequestDirector.java:573)at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:425)at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:820)at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:754)at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:732)at com.otitan.tgs.util.WebServiceUtil.get(WebServiceUtil.java:129)at com.otitan.tgs.api.impl.TrainQueryAPIImpl.test(TrainQueryAPIImpl.java:100)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)at java.lang.reflect.Method.invoke(Unknown Source)at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44)at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15)at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41)at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20)at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:76)at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50)at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193)at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52)at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191)at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42)at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184)at org.junit.runners.ParentRunner.run(ParentRunner.java:236)at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:49)at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38)at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467)at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683)at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390)at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)
解决办法就是：
