WebService开发笔记 1中我们创建了一个WebService简单实例,下面我们通过一个简单的用户口令验证机制来加强一下WebService的安全性:

1.修改WebService 服务端 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.服务端添加passwordCallbackClass回调类,该类进行用户口令验证:
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.客户端修改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.客户端添加passwordCallback类,通过该类设置访问口令
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单元测试程序:
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);
}
}
