注意:以下客户端调用代码中获取服务端ws实例,都是通过CXF 入门: 远程接口调用方式实现
直入正题!
以下是服务端配置
========================================================
一,web.xml配置,具体不在详述
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app> <context-param> <param-name>contextConfigLocation</param-name> <!--ws-context.xml(必须)是cxf配置文件, wssec.xml可选,作用可以打印出加密信息类容 --> <param-value>WEB-INF/ws-context.xml,WEB-INF/wssec.xml</param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <servlet> <servlet-name>CXFServlet</servlet-name> <display-name>CXF Servlet</display-name> <servlet-class> org.apache.cxf.transport.servlet.CXFServlet </servlet-class> <load-on-startup>0</load-on-startup> </servlet> <servlet-mapping> <servlet-name>CXFServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping> </web-app>
二,ws具体代码
简单的接口
import javax.jws.WebService; @WebService() public interface WebServiceSample { String say(String name); }
接口具体实现类
public class WebServiceSampleImpl implements WebServiceSample { public String say(String name) { return "你好," + name; } }
三,ws回调函数,必须实现javax.security.auth.callback.CallbackHandler
从cxf2.4.x后校验又cxf内部实现校验,所以不必自己校验password是否相同,但客户端必须设置,详情请参考:http://cxf.apache.org/docs/24-migration-guide.html的Runtime Changes片段
回调函数WsAuthHandler代码,校验客户端请求是否合法 ,合法就放行,否则拒绝执行任何操作
import java.io.IOException; import javax.security.auth.callback.Callback; import javax.security.auth.callback.CallbackHandler; import javax.security.auth.callback.UnsupportedCallbackException; import org.apache.cxf.interceptor.Fault; import org.apache.ws.security.WSPasswordCallback; import org.apache.xmlbeans.impl.soap.SOAPException; public class WsAuthHandler implements CallbackHandler { public void handle(Callback[] callbacks) throws IOException, UnsupportedCallbackException { for (int i = 0; i < callbacks.length; i++) { WSPasswordCallback pc = (WSPasswordCallback) callbacks[i]; String identifier = pc.getIdentifier(); int usage = pc.getUsage(); if (usage == WSPasswordCallback.USERNAME_TOKEN) {// 密钥方式USERNAME_TOKEN // username token pwd... // ▲这里的值必须和客户端设的值相同,从cxf2.4.x后校验方式改为cxf内部实现校验,不必自己比较password是否相同 // 请参考:http://cxf.apache.org/docs/24-migration-guide.html的Runtime // Changes片段 pc.setPassword("testPassword");// ▲【这里非常重要】▲ // ▲PS 如果和客户端不同将抛出org.apache.ws.security.WSSecurityException: // The // security token could not be authenticated or // authorized异常,服务端会认为客户端为非法调用 } else if (usage == WSPasswordCallback.SIGNATURE) {// 密钥方式SIGNATURE // set the password for client's keystore.keyPassword // ▲这里的值必须和客户端设的值相同,从cxf2.4.x后校验方式改为cxf内部实现校验,不必自己比较password是否相同; // 请参考:http://cxf.apache.org/docs/24-migration-guide.html的Runtime // Changes片段 pc.setPassword("testPassword");// //▲【这里非常重要】▲ // ▲PS:如果和客户端不同将抛出org.apache.ws.security.WSSecurityException:The // security token could not be authenticated or // authorized异常,服务端会认为客户端为非法调用 } //不用做其他操作 } } }
四,CXF配置ws-context.xml:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd"> <import resource="classpath:META-INF/cxf/cxf.xml" /> <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <!-- 以上未基本配置,必须,位置在cxf jar中 --> <jaxws:endpoint id="webServiceSample" address="/WebServiceSample" implementor="com.service.impl.WebServiceSampleImpl"> <!--inInterceptors表示被外部调用时,调用此拦截器 --> <jaxws:inInterceptors> <bean class="org.apache.cxf.binding.soap.saaj.SAAJInInterceptor" /> <bean class="org.apache.cxf.ws.security.wss4j.WSS4JInInterceptor"> <constructor-arg> <map> <!-- 设置加密类型 --> <entry key="action" value="UsernameToken" /> <!-- 设置密码类型为明文 --> <entry key="passwordType" value="PasswordText" /> <!--<entry key="action" value="UsernameToken Timestamp" /> 设置密码类型为加密<entry key="passwordType" value="PasswordDigest" /> --> <entry key="passwordCallbackClass" value="com.service.handler.WsAuthHandler" /> </map> </constructor-arg> </bean> </jaxws:inInterceptors> </jaxws:endpoint> </beans>
CXF配置wssec.xml(可选),用于配置输出校验的具体信息
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cxf="http://cxf.apache.org/core" xmlns:wsa="http://cxf.apache.org/ws/addressing" xmlns:http="http://cxf.apache.org/transports/http/configuration" xmlns:wsrm-policy="http://schemas.xmlsoap.org/ws/2005/02/rm/policy" xmlns:wsrm-mgr="http://cxf.apache.org/ws/rm/manager" xsi:schemaLocation=" http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd http://cxf.apache.org/transports/http/configuration http://cxf.apache.org/schemas/configuration/http-conf.xsd http://schemas.xmlsoap.org/ws/2005/02/rm/policy http://schemas.xmlsoap.org/ws/2005/02/rm/wsrm-policy.xsd http://cxf.apache.org/ws/rm/manager http://cxf.apache.org/schemas/configuration/wsrm-manager.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <cxf:bus> <cxf:features> <cxf:logging /> <wsa:addressing /> </cxf:features> </cxf:bus> </beans>
服务端代码及配置到此结束!!!
=========================================================
=========================================================
以下是客户端配置,主要是回调函数,在客户端调用服务端前被调用,负责安全信息的设置
----------------------------------------------------------------------------------------
一,先实现回调函数WsClinetAuthHandler,同样必须实现javax.security.auth.callback.CallbackHandler
import java.io.IOException; import javax.security.auth.callback.Callback; import javax.security.auth.callback.CallbackHandler; import javax.security.auth.callback.UnsupportedCallbackException; import org.apache.ws.security.WSPasswordCallback; public class WsClinetAuthHandler implements CallbackHandler { public void handle(Callback[] callbacks) throws IOException, UnsupportedCallbackException { for (int i = 0; i < callbacks.length; i++) { WSPasswordCallback pc = (WSPasswordCallback) callbacks[i]; System.out.println("identifier: " + pc.getIdentifier()); // 这里必须设置密码,否则会抛出:java.lang.IllegalArgumentException: pwd == null // but a password is needed pc.setPassword("testPassword");// ▲【这里必须设置密码】▲ } } }
二,客户端调用代码:
import java.util.ArrayList; import java.util.HashMap; import java.util.Map; import org.apache.cxf.binding.soap.saaj.SAAJOutInterceptor; import org.apache.cxf.jaxws.JaxWsProxyFactoryBean; import org.apache.cxf.ws.security.wss4j.WSS4JOutInterceptor; import org.apache.ws.security.WSConstants; import org.apache.ws.security.handler.WSHandlerConstants; import test.saa.client.WebServiceSample; import test.saa.handler.WsClinetAuthHandler; public class TestClient { public static void main(String[] args) { // 以下和服务端配置类似,不对,应该说服务端和这里的安全验证配置一致 Map<String, Object> outProps = new HashMap<String, Object>(); outProps.put(WSHandlerConstants.ACTION, WSHandlerConstants.USERNAME_TOKEN); outProps.put(WSHandlerConstants.USER, "admin"); outProps.put(WSHandlerConstants.PASSWORD_TYPE, WSConstants.PW_TEXT); // 指定在调用远程ws之前触发的回调函数WsClinetAuthHandler,其实类似于一个拦截器 outProps.put(WSHandlerConstants.PW_CALLBACK_CLASS, WsClinetAuthHandler.class.getName()); ArrayList list = new ArrayList(); // 添加cxf安全验证拦截器,必须 list.add(new SAAJOutInterceptor()); list.add(new WSS4JOutInterceptor(outProps)); JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean(); // WebServiceSample服务端接口实现类,这里并不是直接把服务端的类copy过来,具体请参考http://learning.iteye.com/blog/1333223 factory.setServiceClass(WebServiceSample.class); // 设置ws访问地址 factory.setAddress("http://localhost:8080/cxf-wssec/services/WebServiceSample"); //注入拦截器,用于加密安全验证信息 factory.getOutInterceptors().addAll(list); WebServiceSample service = (WebServiceSample) factory.create(); String response = service.say("2012"); System.out.println(response); } }
客户端到此结束!!!!
========================================================================

PS:客户端的另一种调用方式,主要通过配置文件,不过需要spring bean的配置文件(第一种就不用牵扯到spring的配置,比较通用吧!)
一,回调函数WsClinetAuthHandler不变,和上面一样
二,client-beans.xml安全验证配置文件,具体信息看注释,如下:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schema/jaxws.xsd"> <!--这里无非是通过配置来替代JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean()创建代理并实例化一个ws--> <bean id="client" class="test.saa.client.WebServiceSample" factory-bean="clientFactory" factory-method="create" /> <!-- 通过代理创建ws实例 --> <bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean"> <property name="serviceClass" value="test.saa.client.WebServiceSample" /> <!-- ws地址,也可以是完整的wsdl地址 --> <property name="address" value="http://localhost:8080/cxf-wssec/services/WebServiceSample" /> <!--outInterceptors表示调用外部指定ws时,调用此拦截器 --> <property name="outInterceptors"> <list> <bean class="org.apache.cxf.binding.soap.saaj.SAAJOutInterceptor" /> <ref bean="wss4jOutConfiguration" /> </list> </property> </bean> <bean id="wss4jOutConfiguration" class="org.apache.cxf.ws.security.wss4j.WSS4JOutInterceptor"> <property name="properties"> <map> <!-- 设置加密类型 ,服务端需要和这里的设置保持一致--> <entry key="action" value="UsernameToken" /> <entry key="user" value="admin" /> <!-- 设置密码为明文 ,服务端需要和这里的设置保持一致--> <entry key="passwordType" value="PasswordText" /> <!-- <entry key="action" value="UsernameToken Timestamp" /> <entry key="user" value="adminTest" /> 设置密码类型为加密方式,服务端需要和这里的设置保持一致<entry key="passwordType" value="PasswordDigest" /> --> <entry key="passwordCallbackRef"> <ref bean="passwordCallback" /> </entry> </map> </property> </bean> <bean id="passwordCallback" class="test.saa.handler.WsClinetAuthHandler" /> </beans>
三,具体调用服务端代码:
import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import test.saa.client.WebServiceSample; public final class Client { public static void main(String args[]) throws Exception { //加载配置 ApplicationContext context = new ClassPathXmlApplicationContext( new String[] { "test/saa/client-beans.xml" }); //获取ws实例 WebServiceSample client = (WebServiceSample) context.getBean("client"); String response = client.say("2012"); System.out.println("Response: " + response); } }
