java.security.cert.CertificateException: No name matching IP found SpringMVC

java.security.cert.CertificateException: No name matching localhost found 解释；安全证书异常，IP地址找不到
解决方案如下：程序加入static里面的代码块就OK了
代码的意思就是程序默认这个IP地址是安全可访问的
Problem Configured Tomcat to support SSL and deployed this simple hello world web service. And use following client connect to the deployed web service over SSL connection :

package com.mkyong.client; import java.net.URL; import javax.xml.namespace.QName; import javax.xml.ws.Service; import com.mkyong.ws.HelloWorld; public class HelloWorldClient{ public static void main(String[] args) throws Exception { URL url = new URL("https://localhost:8443/HelloWorld/hello?wsdl"); QName qname = new QName("http://ws.mkyong.com/", "HelloWorldImplService"); Service service = Service.create(url, qname); HelloWorld hello = service.getPort(HelloWorld.class); System.out.println(hello.getHelloWorldAsString()); } }

Copy
It hits “No name matching localhost found” exception :

Caused by: javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No name matching localhost found at com.sun.net.ssl.internal.ssl.Alerts.getSSLException(Alerts.java:174) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.fatal(SSLSocketImpl.java:1611) at com.sun.net.ssl.internal.ssl.Handshaker.fatalSE(Handshaker.java:187) at com.sun.net.ssl.internal.ssl.Handshaker.fatalSE(Handshaker.java:181) ......

Solution This problem and solution is well explained in this article, you can use a Transport Security (SSL) Workaround for your “localhost” development environment.
To fix it, add a javax.net.ssl.HostnameVerifier() method to override the existing hostname verifier like this :

package com.mkyong.client; import java.net.URL; import javax.xml.namespace.QName; import javax.xml.ws.Service; import com.mkyong.ws.HelloWorld; public class HelloWorldClient{ static { //for localhost testing only javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier( new javax.net.ssl.HostnameVerifier(){public boolean verify(String hostname, javax.net.ssl.SSLSession sslSession) { if (hostname.equals("localhost")) { return true; } return false; } }); } public static void main(String[] args) throws Exception { URL url = new URL("https://localhost:8443/HelloWorld/hello?wsdl"); QName qname = new QName("http://ws.mkyong.com/", "HelloWorldImplService"); Service service = Service.create(url, qname); HelloWorld hello = service.getPort(HelloWorld.class); System.out.println(hello.getHelloWorldAsString()); } }
