本文介绍了一个基于HTTPS访问WebService的实际案例，包括配置SSL、创建WebService接口及其实现、配置XML文件等步骤，最后通过Java客户端实现了对WebService的成功调用。

部署运行你感兴趣的模型镜像

因为要做个Https访问WebService的功能，所以做例子，对于技术本来就不怎么样的我，这个痛苦啊，幸好，最后还是出来了。。

上步骤：

1. 新建Web工程，Maven依赖如下，因为有别的例子，所以对这个来说可能多了，不一一弄了，直接上全版

  </dependencies>

2. 生成密钥文件

由于SSL需要密钥文件，所以要先生成一个.keystore文件。

生成方法：（1）在cmd中输入命令：

keytool -genkey -alias tomcat-server -keyalg RSA -keypass changeit -storepass 
changeit -validity 3600

（2）按照提示一次输入相应的内容，最后一步输入“y”即可。

（3）在运行命令的目录下就生成了.keystore文件。密码为：changeit。修改文件名，例如，hello.keystore，否则程序不识别。

将hello.keystore文件拷贝到刚刚建好的Web工程根目录下。

3.Tomcat添加SSL支持

\apache-tomcat-7.0.40\conf\server.xml中，默认8443的Port被注释掉，这里需要放开，并添加keystore文件属性，添加后如下

<Connector SSLEnabled="true" clientAuth="false" keystoreFile="F:\WorkSpace\cxf-web\hello.keystore" 
keystorePass="changeit" maxThreads="150" port="8443" protocol="HTTP/1.1" 
scheme="https" secure="true" sslProtocol="TLS"/>

添加后启动Tomcat，访问https://localhost:8443/，出现“

此网站的安全证书有问题。”

就表示已经接近配置成功，大胆的点击

继续浏览此网站(不推荐)。

后出现Tomcat页面，证明配置成功！~

4. 在Web工程中新建接口Hello

package com.uuzz.sporttery;

import java.util.List;

import javax.jws.WebParam;
import javax.jws.WebService;

@WebService
public interface Hello {

    String SayHi(@WebParam(name = "text") String text);

    String SayHiToUser(User user);

    String[] SayHiToUserList(List<User> userList);

}

5. 添加接口实现

package com.uuzz.sporttery;

import java.util.LinkedHashMap;
import java.util.List;
import java.util.Map;

import javax.jws.WebService;

@WebService(endpointInterface = "com.uuzz.sporttery.Hello", serviceName = "Hello")
public class HelloImpl implements Hello {

    Map<Integer, User> users = new LinkedHashMap<Integer, User>();

    public String SayHi(String text) {
	return "Hello " + text;
    }

    public String SayHiToUser(User user) {
	users.put(users.size() + 1, user);
	return "Hello " + user.getUserName();
    }

    public String[] SayHiToUserList(List<User> userList) {
	String[] result = new String[userList.size()];
	int i = 0;
	for (User u : userList) {
	    result[i] = "Hello " + u.getUserName();
	    i++;
	}
	return result;
    }

}

6. 配置XML文件，加载服务，在/WEB-INF下新建sun-jaxws.xml

<?xml version="1.0" encoding="UTF-8"?>  
<endpoints xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime"  
    version="2.0">  
    <endpoint name="HelloImplWS" implementation="com.uuzz.sporttery.HelloImpl"  
        url-pattern="/helloImpl" />  
</endpoints>

并在web.xml中添加以下代码

<login-config>  
        <auth-method>CLIENT-CERT</auth-method>  
        <realm-name>Client Cert Users-only Area</realm-name>  
    </login-config>  
    <security-constraint>  
            
        <web-resource-collection >  
            <web-resource-name >SSL</web-resource-name>  
            <url-pattern>/*</url-pattern>  
        </web-resource-collection>  
        <user-data-constraint>  
            <transport-guarantee>CONFIDENTIAL</transport-guarantee>  
        </user-data-constraint>  
	</security-constraint>  
	
	<listener>    
        <listener-class>    
            com.sun.xml.ws.transport.http.servlet.WSServletContextListener    
        </listener-class>    
    </listener>    
    <servlet>    
        <servlet-name>helloImpl</servlet-name>    
        <servlet-class>    
            com.sun.xml.ws.transport.http.servlet.WSServlet    
        </servlet-class>    
    </servlet>    
    <servlet-mapping>    
        <servlet-name>helloImpl</servlet-name>    
        <url-pattern>/helloImpl</url-pattern>    
	</servlet-mapping>

7. WebService部分实现完成，使用Maven打包后，将WebService.war包放入Tomcat的webapps后，启动Tomcat，访问https://localhost:8443/WebService/helloImpl?wsdl，出现WSDL，表示WebService的服务正式发布成功啦！

8. 然后就只剩调用了，新建Java工程，先上Maven依赖

<dependencies>
		<dependency>
			<groupId>org.apache.axis2</groupId>
			<artifactId>axis2-kernel</artifactId>
			<version>1.6.2</version>
		</dependency>

		<dependency>
			<groupId>org.apache.axis2</groupId>
			<artifactId>axis2-adb</artifactId>

		</dependency>

		<dependency>

			<artifactId>cxf</artifactId>
			<version>2.7.5</version>
			<type>pom</type>
		</dependency>
		<dependency>
			<groupId>ws-commons</groupId>
			<artifactId>axiom-api</artifactId>
			<version>1.1.1</version>
		</dependency>
		<dependency>
			<groupId>commons-logging</groupId>
			<artifactId>commons-logging</artifactId>
			<version>1.1.3</version>
		</dependency>
		<dependency>

			<version>1.6.2</version>
		</dependency>
		<dependency>

			<artifactId>axis2-java2wsdl</artifactId>
			<version>1.6.2</version>
		</dependency>
		<dependency>
			<groupId>ant</groupId>
			<artifactId>ant-apache-log4j</artifactId>
			<version>1.6.5</version>
		</dependency>
	</dependencies>

然后就是调用类啦，使用Service类调用，新建Class类，具体如下

package com.uuzz.sporttery.client;

import java.rmi.RemoteException;

import javax.xml.namespace.QName;
import javax.xml.rpc.ParameterMode;
import javax.xml.rpc.ServiceException;
import javax.xml.rpc.encoding.XMLType;

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

public class HelloClientHttps {

    public static void main(String[] args) throws ServiceException,
	    RemoteException {

	System.setProperty("javax.net.ssl.keyStore",
		"F:\\WorkSpace\\cxf-web\\hello.keystore");

	System.setProperty("javax.net.ssl.keyStorePassword", "changeit");

	System.setProperty("javax.net.ssl.trustStore",
		"F:\\WorkSpace\\cxf-web\\hello.keystore");

	System.setProperty("javax.net.ssl.trustStorePassword", "changeit");

	Service _service = new Service();

	Call _call = (Call) _service.createCall();

	_call.setTimeout(1000);

	_call.setTargetEndpointAddress("https://localhost:8443/WebService/helloImpl");

	QName opAddEntry = new QName("http://sporttery.uuzz.com/", "SayHi");
	_call.setOperationName(opAddEntry);

	_call.addParameter("text", XMLType.XSD_STRING, ParameterMode.IN);

	_call.setReturnType(XMLType.XSD_STRING);

	Object result = _call.invoke(new String[] { "My Friend" });
	System.out.println(result);
    }

}

9. 然后直接run就可以啦，执行结果：Hello My Friend
