XML_RPC用户验证实例(高级)

Server端：
创建一个web工程，工程名XML_RPC，导入除client以外的4个jar包

业务逻辑类：

package demo.xmlrpc.action;

public class Calculator {
    public int add(int i1, int i2) {
            return i1 + i2;
    }
    public int subtract(int i1, int i2) {
            return i1 - i2;
    }
}

用户验证逻辑类：

package demo.xmlrpc.authentication;

import org.apache.xmlrpc.XmlRpcException;
import org.apache.xmlrpc.XmlRpcRequest;
import org.apache.xmlrpc.common.XmlRpcHttpRequestConfig;
import org.apache.xmlrpc.server.AbstractReflectiveHandlerMapping;
import org.apache.xmlrpc.server.PropertyHandlerMapping;
import org.apache.xmlrpc.server.XmlRpcHandlerMapping;
import org.apache.xmlrpc.webserver.XmlRpcServlet;

public class MyServlet extends XmlRpcServlet {
	private static final long serialVersionUID = 1L;

	private boolean isAuthenticated(String pUserName, String pPassword) {
		return "foo".equals(pUserName) && "bar".equals(pPassword);
	}

	protected XmlRpcHandlerMapping newXmlRpcHandlerMapping() throws XmlRpcException {
		PropertyHandlerMapping mapping = (PropertyHandlerMapping) super
				.newXmlRpcHandlerMapping();
		
		AbstractReflectiveHandlerMapping.AuthenticationHandler handler = new AbstractReflectiveHandlerMapping.AuthenticationHandler() {
			public boolean isAuthorized(XmlRpcRequest pRequest) {
				XmlRpcHttpRequestConfig config = (XmlRpcHttpRequestConfig) pRequest
						.getConfig();
				return isAuthenticated(config.getBasicUserName(), config
						.getBasicPassword());
			};
		};
		mapping.setAuthenticationHandler(handler);
		return mapping;
	}
}

服务控制Servlet：

package demo.xmlrpc.authentication;

import java.io.IOException;

import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.xmlrpc.XmlRpcException;
import org.apache.xmlrpc.server.PropertyHandlerMapping;
import org.apache.xmlrpc.server.XmlRpcServerConfigImpl;
import org.apache.xmlrpc.webserver.XmlRpcServletServer;

import demo.xmlrpc.action.Calculator;
import demo.xmlrpc.action.HelloHandlerImpl;

public class MyAuthenticationServlet extends MyServlet{

	private static final long serialVersionUID = 1L;

	private XmlRpcServletServer server;

    public void init(ServletConfig pConfig) throws ServletException {
          super.init(pConfig);
          try {
                // 创建一个XmlRpcServletServer对象
                server = new XmlRpcServletServer();
                
                // 创建一个接收器并映射到XmlRpcServletServer对象
                PropertyHandlerMapping phm =(PropertyHandlerMapping)newXmlRpcHandlerMapping();
                phm.addHandler("HelloHandler", HelloHandlerImpl.class);
                phm.addHandler("Calculator", Calculator.class);
              
                server.setHandlerMapping(phm);
                // 更多XmlRpcServletServer对象设置 
                XmlRpcServerConfigImpl serverConfig = (XmlRpcServerConfigImpl)server.getConfig();
                serverConfig.setEnabledForExtensions(true);
                serverConfig.setContentLengthOptional(false);
          } catch (XmlRpcException e) {
                try {
                      log("Failed to create XmlRpcServer: " + e.getMessage(), e);
                } catch (Throwable ignore) {
                }
                throw new ServletException(e);
          }
    }

    public void doPost(HttpServletRequest pRequest, HttpServletResponse pResponse)
          throws IOException, ServletException {
          server.execute(pRequest, pResponse);
    }

}

在web.xml文件添加如下内容：

  	<servlet>
		<servlet-name>Authentication</servlet-name>
		<servlet-class>demo.xmlrpc.authentication.MyAuthenticationServlet</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>Authentication</servlet-name>
		<url-pattern>/Authentication</url-pattern>
	</servlet-mapping>

创建一个包，里面添加一个配置文件，名字如下。两个名字一定不能变，这很雷人的，

框架规定的。

包名：org.apache.xmlrpc.webserver

文件名为：XmlRpcServlet.properties

文件内容为：Calculator=demo.xmlrpc.action.Calculator

Client端：
创建一个普通工程，导入除server以外的4个jar包

远程客户端调用类：

package demo.xmlrpc;

import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.Vector;

import org.apache.xmlrpc.XmlRpcException;
import org.apache.xmlrpc.client.XmlRpcClient;
import org.apache.xmlrpc.client.XmlRpcClientConfigImpl;

public class Client1 {

	public static void main(String[] args) {

		try {
			// 客户端配置对象，并且设置用户名密码
			XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
			config.setBasicUserName("foo");
			config.setBasicPassword("bar");
			config.setServerURL(new URL("http://192.168.1.217:8080/XML_RPC/Authentication"));

			//创建一个XmlRpcClient对象，并给它绑定一个配置对象
			XmlRpcClient client = new XmlRpcClient();
			client.setConfig(config);
			
			// 创建参数集合
			Vector<Integer> params= new Vector<Integer>();
			params.addElement(3);
			params.addElement(8);
			Integer result=(Integer)client.execute("Calculator.add",params);

			System.out.println(result);

		} catch (MalformedURLException e) {
			System.out.println(e.toString());
		} catch (XmlRpcException e) {
			System.out.println(e.toString());
		} catch (IOException e) {
			e.printStackTrace();
		}

	}

}

部署启动Server端的web工程，运行Client端的程序。返回结果为11。
