注意：以下客戶端調用代碼中獲取服務端ws實例，都是通過CXF 入門: 遠程接口調用方式實現
?
直入正題！
以下是服務端配置
========================================================
一，web.xml配置,具體不在詳述
<?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(必須）是cxf配置文件, wssec.xml可選，作用可以打印出加密信息類容 -->
<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具體代碼
簡單的接口
?
import javax.jws.WebService;
@WebService()
public interface WebServiceSample {
String say(String name);
}
?
?
接口具體實現類
?
public class WebServiceSampleImpl implements WebServiceSample {
public String say(String name) {
return "你好," + name;
}
}
?
?
?
三,ws回調函數,必須實現javax.security.auth.callback.CallbackHandler
從cxf2.4.x后校驗又cxf內部實現校驗，所以不必自己校驗password是否相同，但客戶端必須設置，詳情請參考：http://cxf.apache.org/docs/24-migration-guide.html的Runtime ?Changes片段
?
回調函數WsAuthHandler代碼，校驗客戶端請求是否合法 ，合法就放行，否則拒絕執行任何操作
?
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) {// 密鑰方式USERNAME_TOKEN
// username token pwd...
// ▲這里的值必須和客戶端設的值相同,從cxf2.4.x后校驗方式改為cxf內部實現校驗，不必自己比較password是否相同
// 請參考：http://cxf.apache.org/docs/24-migration-guide.html的Runtime
// Changes片段
pc.setPassword("testPassword");// ▲【這里非常重要】▲
// ▲PS 如果和客戶端不同將拋出org.apache.ws.security.WSSecurityException:
// The
// security token could not be authenticated or
// authorized異常，服務端會認為客戶端為非法調用
} else if (usage == WSPasswordCallback.SIGNATURE) {// 密鑰方式SIGNATURE
// set the password for client's keystore.keyPassword
// ▲這里的值必須和客戶端設的值相同,從cxf2.4.x后校驗方式改為cxf內部實現校驗，不必自己比較password是否相同;
// 請參考：http://cxf.apache.org/docs/24-migration-guide.html的Runtime
// Changes片段
pc.setPassword("testPassword");// //▲【這里非常重要】▲
// ▲PS:如果和客戶端不同將拋出org.apache.ws.security.WSSecurityException:The
// security token could not be authenticated or
// authorized異常，服務端會認為客戶端為非法調用
}
//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，必須，位置在cxf jar中 -->
<jaxws:endpoint id="webServiceSample" address="/WebServiceSample"
implementor="com.service.impl.WebServiceSampleImpl">
<!--inInterceptors表示被外部調用時，調用此攔截器 -->
<jaxws:inInterceptors>
<bean class="org.apache.cxf.binding.soap.saaj.SAAJInInterceptor" />
<bean class="org.apache.cxf.ws.security.wss4j.WSS4JInInterceptor">
<constructor-arg>
<map>
<!-- 設置加密類型 -->
<entry key="action" value="UsernameToken" />
<!-- 設置密碼類型為明文 -->
<entry key="passwordType" value="PasswordText" />
<!--<entry key="action" value="UsernameToken Timestamp" /> 設置密碼類型為加密<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(可選)，用于配置輸出校驗的具體信息
?
<?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="

<cxf:bus>
<cxf:features>

</cxf:features>
</cxf:bus>
</beans>
?
服務端代碼及配置到此結束！！！
?
=========================================================
=========================================================
以下是客戶端配置，主要是回調函數，在客戶端調用服務端前被調用，負責安全信息的設置
----------------------------------------------------------------------------------------
?
?
一，先實現回調函數WsClinetAuthHandler，同樣必須實現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());
// 這里必須設置密碼，否則會拋出：java.lang.IllegalArgumentException: pwd == null
// but a password is needed
pc.setPassword("testPassword");// ▲【這里必須設置密碼】▲
}
}
}
?
二，客戶端調用代碼：
?
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) {
// 以下和服務端配置類似，不對，應該說服務端和這里的安全驗證配置一致
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);
// 指定在調用遠程ws之前觸發的回調函數WsClinetAuthHandler，其實類似于一個攔截器
outProps.put(WSHandlerConstants.PW_CALLBACK_CLASS,
WsClinetAuthHandler.class.getName());
ArrayList list = new ArrayList();
// 添加cxf安全驗證攔截器，必須
list.add(new SAAJOutInterceptor());
list.add(new WSS4JOutInterceptor(outProps));
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
// WebServiceSample服務端接口實現類，這里并不是直接把服務端的類copy過來，具體請參考http://learning.iteye.com/blog/1333223
factory.setServiceClass(WebServiceSample.class);
// 設置ws訪問地址
factory.setAddress("http://localhost:8080/cxf-wssec/services/WebServiceSample");
//注入攔截器，用于加密安全驗證信息
factory.getOutInterceptors().addAll(list);
WebServiceSample service = (WebServiceSample) factory.create();
String response = service.say("2012");
System.out.println(response);
}
}
?客戶端到此結束！！！！
========================================================================
#######################################################################
?
PS:客戶端的另一種調用方式，主要通過配置文件,不過需要spring bean的配置文件（第一種就不用牽扯到spring的配置，比較通用吧！）
?
一，回調函數WsClinetAuthHandler不變，和上面一樣
二，client-beans.xml安全驗證配置文件，具體信息看注釋，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">
<!--這里無非是通過配置來替代JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean()創建代理并實例化一個ws-->
<bean id="client" class="test.saa.client.WebServiceSample"
factory-bean="clientFactory" factory-method="create" />
<!-- 通過代理創建ws實例 -->
<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表示調用外部指定ws時，調用此攔截器 -->
<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>
<!-- 設置加密類型 ,服務端需要和這里的設置保持一致-->
<entry key="action" value="UsernameToken" />
<entry key="user" value="admin" />
<!-- 設置密碼為明文 ,服務端需要和這里的設置保持一致-->
<entry key="passwordType" value="PasswordText" />
<!-- <entry key="action" value="UsernameToken Timestamp" /> <entry key="user"
value="adminTest" /> 設置密碼類型為加密方式,服務端需要和這里的設置保持一致<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，具體調用服務端代碼：
?
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 {
//加載配置
ApplicationContext context = new ClassPathXmlApplicationContext(
new String[] { "test/saa/client-beans.xml" });
//獲取ws實例
WebServiceSample client = (WebServiceSample) context.getBean("client");
String response = client.say("2012");
System.out.println("Response: " + response);
}
}
?
到此客戶端第二種實現方式結束
GOOD LUCKY!!!
如有不明，請指教！！！
