Java Https Soap Server(Tomcat-Axis2)

Posted on by — No Comments ↓

1、%Tomcat%/server/server.xml
找到下面一段：

<!--
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
               maxThreads="150" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLS" />
-->

替换为：

<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" SSLEnabled="true"  
	    maxThreads="150" scheme="https"  secure="true"
	    clientAuth="false" sslProtocol="TLS"
	    disableUploadTimeout="true" enableLookups="false"
	    keystoreFile="D:/JavaContainer/apache-tomcat-6.0.35-x86/myKeyStore.jks"
	    keystorePass="sslTestPwd"
/>

这样，就可以用https://127.0.0.1:8443访问Tomcat了。

2、在需要使用https项目的axis2.xml文件中，增加下面内容

        <!--修改-->
	<transportReceiver name="http"
		class="org.apache.axis2.transport.http.AxisServletListener">
		<parameter name="port">8080</parameter>
	</transportReceiver>
        <!--新增-->
	<transportReceiver name="https"
		class="org.apache.axis2.transport.http.AxisServletListener">
		<parameter name="port">8443</parameter>
	</transportReceiver>

这样，该WebService就可以使用https进行访问了：）

1、SoapClient

package com.neohope;

	{
		//HelloHttp("http://localhost:80/Hello.asmx");
		HelloHttps("https://localhost:443/Hello.asmx","myTrustStore.jks","sslTestPwd");
	}
}

3、SoapClientWithTrustManagerTest
