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);
- }
- }
到此客户端第二种实现方式结束
GOOD LUCKY!!!
如有不明,请指教!!!

客户端调用,这行代码是必须的吗,有什么作用吗?
outProps.put(WSHandlerConstants.USER, "admin");
outProps.put(WSHandlerConstants.USER, "admin");
5 楼 xiangximingong 2013-09-18 引用
我想问下,就是客户端传入错误的密码,也会抛一个异常,但这个异常我不知道在哪捕获,也不知道怎么通知客户端密码错误!能否指教下……
4 楼 zhenglongfei 2013-07-25 引用
想不通,为什么要在服务端要在set一下呢??

我想问下,为什么在服务端的回调函数里面当还要setPassword呢?我很郁闷的是,我在客户端明明已经设定了密码,可是服务端却拿不到,而且如果有服务端不设定密码就抛异常,我想问下到底是怎么样校验的呢?
我也是遇到这个问题。。
在服务端setPassword,那密码校验还有什么意义
1,为什么不设置密码会抛异常:
--既然要把服务加密,就要设置密码,要不然怎么加密,怎么知道哪些客户端是有权限访问的,就像买了一把锁,连自己(服务端)都不知道钥匙是怎么,那别人(客户端)怎么开这把锁
2,服务端设置密码是为了给自己上一把锁,如果要访问它必须有开这把锁的钥匙,即密码,有钥匙还要保证这个钥匙可以开这把锁,即客户端拿的密码是否和服务端锁的密码一致
