在WebService開發(fā)筆記 1中我們創(chuàng)建了一個WebService簡單實例,下面我們通過一個簡單的用戶口令驗證機制來加強一下WebService的安全性:
1.修改WebService 服務(wù)端 spring 配置文件 ws-context.xml
<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://cxf.apache.org/jaxws
http://cxf.apache.org/schemas/jaxws.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd" default-autowire="byName" default-lazy-init="true"> <jaxws:endpoint id="webServiceSample" address="/WebServiceSample" implementor="cn.org.coral.biz.examples.webservice.WebServiceSampleImpl"> <jaxws:inInterceptors> <bean class="org.apache.cxf.binding.soap.saaj.SAAJInInterceptor" /> <bean class="org.apache.cxf.ws.security.wss4j.WSS4JInInterceptor"> <constructor-arg> <map> <entry key="action" value="UsernameToken" /> <entry key="passwordType" value="PasswordText" /> <entry key="passwordCallbackClass" value="cn.org.coral.biz.examples.webservice.handler.WsAuthHandler" /> </map> </constructor-arg> </bean> </jaxws:inInterceptors> </jaxws:endpoint> </beans>
2.服務(wù)端添加passwordCallbackClass回調(diào)類,該類進行用戶口令驗證:
package cn.org.coral.biz.examples.webservice.handler; 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 WsAuthHandler implements CallbackHandler{ public void handle(Callback[] callbacks) throws IOException, UnsupportedCallbackException { WSPasswordCallback pc = (WSPasswordCallback) callbacks[0]; if (pc.getIdentifer().equals("ws-client")){ if (!pc.getPassword().equals("admin")) { throw new SecurityException("wrong password"); } }else{ throw new SecurityException("wrong username"); } } }
3.客戶端修改spring 配置文件 wsclient-context.xml 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://cxf.apache.org/jaxws
http://cxf.apache.org/schemas/jaxws.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd" default-autowire="byName" default-lazy-init="true"> <!-- ws clinet --> <bean id="webServiceSampleClient" class="cn.org.coral.biz.examples.webservice.WebServiceSample" factory-bean="webServiceSampleClientFactory" factory-method="create" /> <bean id="webServiceSampleClientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean"> <property name="serviceClass" value="cn.org.coral.biz.examples.webservice.WebServiceSample" /> <property name="address" value="http://88.148.29.54:8080/aio/services/WebServiceSample" /> <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> <entry key="action" value="UsernameToken" /> <entry key="user" value="ws-client" /> <entry key="passwordType" value="PasswordText" /> <entry> <key> <value>passwordCallbackRef</value> </key> <ref bean="passwordCallback" /> </entry> </map> </property> </bean> <bean id="passwordCallback" class="cn.org.coral.biz.examples.webservice.handler.WsClinetAuthHandler"> </bean> </beans>
4.客戶端添加passwordCallback類,通過該類設(shè)置訪問口令
package cn.org.coral.biz.examples.webservice.handler; 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[0]; int usage = pc.getUsage(); System.out.println("identifier: " + pc.getIdentifer()); System.out.println("usage: " + pc.getUsage()); if (usage == WSPasswordCallback.USERNAME_TOKEN) { // username token pwd... pc.setPassword("admin"); } else if (usage == WSPasswordCallback.SIGNATURE) { // set the password for client's keystore.keyPassword pc.setPassword("keyPassword"); } } } }
5.junit單元測試程序:
package cn.org.coral.biz.examples.webservice; import org.springframework.test.AbstractDependencyInjectionSpringContextTests; import org.springframework.util.Assert; public class TestWebService extends AbstractDependencyInjectionSpringContextTests { WebServiceSample webServiceSampleClient; @Override protected String[] getConfigLocations() { setAutowireMode(AUTOWIRE_BY_NAME); return new String[] { "classpath:/cn/org/coral/biz/examples/webservice/wsclient-context.xml" }; } /** * @param webServiceSampleClient the webServiceSampleClient to set */ public void setWebServiceSampleClient(WebServiceSample webServiceSampleClient) { this.webServiceSampleClient = webServiceSampleClient; } public void testSay(){ String result = webServiceSampleClient.say(" world"); Assert.hasText(result); } }
