非J2EE部署解决方案
基本的实现原理和部分代码如下：
1.客户端访问交银.net系统，由该系统发送请求，访问方式为：http://润乾 报表服务器ip:9090/appsOnlineUms/index.jsp?token=b96335b0db0347bf9b98c4fb2a3fdb38
2.由index.jsp接收到传过来的token值（系统唯一值），
3.根据传过来的token值调用.net系统的定义的WebServices的http://portal.jysld.com/jyportalinterface/
reportrights.asmx方法，此方法里相关有用的信息
index.jsp部分代码：
<%
String token = request.getParameter(“token”);
System.out.println(“传过来的token:” + token);
ReportRightsClient client = new ReportRightsClient();
ReportRightsSoap service = client.getReportRightsSoap();
ReportRightResult reportResult=service.getRight(token);
String displayName= reportResult.getDisplayName();
String Account=reportResult.getAccount();
String raq= reportResult.getReportName();
boolean flag=reportResult.isRight();
session.setAttribute(“flag”, flag);
System.out.println(“别名:”+displayName);
System.out.println(“ACount:”+Account);
System.out.println(“报表名:”+raq);
System.out.println(“是否有权限:”+flag);
%>
4.对WebServices方法的处理两个基本java类：ReportRightsClient.java代码如下：
package com;
import java.net.MalformedURLException;
import java.util.Collection;
import java.util.HashMap;
import javax.xml.namespace.QName;
import org.codehaus.xfire.XFireRuntimeException;
import org.codehaus.xfire.aegis.AegisBindingProvider;
import org.codehaus.xfire.annotations.AnnotationServiceFactory;
import org.codehaus.xfire.annotations.jsr181.Jsr181WebAnnotations;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.jaxb2.JaxbTypeRegistry;
import org.codehaus.xfire.service.Endpoint;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.soap.AbstractSoapBinding;
import org.codehaus.xfire.transport.TransportManager;
import org.tempuri.ReportRightResult;
public class ReportRightsClient {
private static XFireProxyFactory proxyFactory = new XFireProxyFactory();
private HashMap endpoints = new HashMap();
private Service service0;
public ReportRightsClient() {
create0();
Endpoint ReportRightsSoapLocalEndpointEP = service0 .addEndpoint(new QName(“http://tempuri.org/”, “ReportRightsSoapLocalEndpoint”), new QName(“http://tempuri.org/”, “ReportRightsSoapLocalBinding”), “xfire.local://ReportRights”);
endpoints.put(new QName(“http://tempuri.org/”, “ReportRightsSoapLocalEndpoint”), ReportRightsSoapLocalEndpointEP);
Endpoint ReportRightsSoapEP = service0 .addEndpoint(new QName(“http://tempuri.org/”, “ReportRightsSoap”), new QName(“http://tempuri.org/”, “ReportRightsSoap”), “http://portal.jysld.com/jyportalinterface/reportrights.asmx”);
endpoints.put(new QName(“http://tempuri.org/”, “ReportRightsSoap”), ReportRightsSoapEP);
}
public Object getEndpoint(Endpoint endpoint) {
try {
return proxyFactory.create((endpoint).getBinding(), (endpoint).getUrl());
} catch (MalformedURLException e) {
throw new XFireRuntimeException(“Invalid URL”, e);
}
}
public Object getEndpoint(QName name) {
Endpoint endpoint = ((Endpoint) endpoints.get((name)));
if ((endpoint) == null) {
throw new IllegalStateException(“No such endpoint!”);
}
return getEndpoint((endpoint));
}
public Collection getEndpoints() {
return endpoints.values();
}
private void create0() {
TransportManager tm = (org.codehaus.xfire.XFireFactory.newInstance().getXFire().getTransportManager());
HashMap props = new HashMap();
props.put(“annotations.allow.interface”, true);
AnnotationServiceFactory asf = new AnnotationServiceFactory(new Jsr181WebAnnotations(), tm, new AegisBindingProvider(new JaxbTypeRegistry()));
asf.setBindingCreationEnabled(false);
service0 = asf.create((com.ReportRightsSoap.class), props);
{
AbstractSoapBinding soapBinding = asf.createSoap11Binding(service0, new QName(“http://tempuri.org/”, “ReportRightsSoapLocalBinding”), “urn:xfire:transport:local”);
}
{
AbstractSoapBinding soapBinding = asf.createSoap11Binding(service0, new QName(“http://tempuri.org/”, “ReportRightsSoap”), “http://schemas.xmlsoap.org/soap/http”);
}
}
public ReportRightsSoap getReportRightsSoapLocalEndpoint() {
return ((ReportRightsSoap)(this).getEndpoint(new QName(“http://tempuri.org/”, “ReportRightsSoapLocalEndpoint”)));
}
public ReportRightsSoap getReportRightsSoapLocalEndpoint(String url) {
ReportRightsSoap var = getReportRightsSoapLocalEndpoint();
org.codehaus.xfire.client.Client.getInstance(var).setUrl(url);
return var;
}
public ReportRightsSoap getReportRightsSoap() {
return ((ReportRightsSoap)(this).getEndpoint(new QName(“http://tempuri.org/”, “ReportRightsSoap”)));
}
public ReportRightsSoap getReportRightsSoap(String url) {
ReportRightsSoap var = getReportRightsSoap();
org.codehaus.xfire.client.Client.getInstance(var).setUrl(url);
return var;
}
public static void main(String[] args) {
ReportRightsClient client = new ReportRightsClient();
//create a default service endpoint
ReportRightsSoap service = client.getReportRightsSoap();
//TODO: Add custom client code here
//
//service.yourServiceOperationHere();
ReportRightResult reportResult=service.getRight(“b96335b0db0347bf9b98c4fb2a3fdb38″);
String displayName= reportResult.getDisplayName();
String Account=reportResult.getAccount();
String reportName= reportResult.getReportName();
boolean flag=reportResult.isRight();
System.out.println(“别名:”+displayName);
System.out.println(“ACount:”+Account);
System.out.println(“报表名:”+reportName);
System.out.println(“是否有权限:”+flag);
//测试：
//http://localhost:9090/appsOnlineUms/index.jsp?token=b96335b0db0347bf9b98c4fb2a3fdb38
//http://localhost:9090/appsOnlineUms/index.jsp?token=b96335b0db0347bf9b98c4fb2a3fdb36
System.exit(0);
}
}
ReportRightsSoap.java代码如下：
package com;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import org.tempuri.ReportRightResult;
@WebService(name = “ReportRightsSoap”, targetNamespace = “http://tempuri.org/”)
@SOAPBinding(use = SOAPBinding.Use.LITERAL, parameterStyle = SOAPBinding.ParameterStyle.WRAPPED)
public interface ReportRightsSoap {
@WebMethod(operationName = “GetRight”, action = “http://tempuri.org/GetRight”)
@WebResult(name = “GetRightResult”, targetNamespace = “http://tempuri.org/”)
public ReportRightResult getRight(
@WebParam(name = “token”, targetNamespace = “http://tempuri.org/”)
String token);
}
5.根据调用的WebServices对其返回的ReportRightResult结果集得到相关的信息
ReportRightResult reportResult=service.getRight(token);
String displayName= reportResult.getDisplayName();//别名
String Account=reportResult.getAccount();//ACount
String raq= reportResult.getReportName();//报表名
boolean flag=reportResult.isRight();//是否有权限
session.setAttribute(“flag”, flag);
6.由返回的权限判断通过Filter进行页面和数据的过滤
OnlineFilter.java的代码：
package filter;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.*;
public class OnlineFilter extends HttpServlet implements Filter {
private static final long serialVersionUID = 1L;
// private String loginUrl = “”;
public void init(FilterConfig filterConfig) throws ServletException {
// loginUrl = filterConfig.getInitParameter(“exceptUrl”);
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException,
NullPointerException {
RequestDispatcher dispatcher = request
.getRequestDispatcher(“myErrorPage.jsp”);
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse res = (HttpServletResponse) response;
HttpSession session = req.getSession(true);
// 从session里取的权限判断信息
boolean flag = (Boolean) session.getAttribute(“flag”);
System.out.println(“flag:” + flag);
if (!flag) {
// 跳转到登陆页面
dispatcher.forward(request, response);
res.setHeader(“Cache-Control”, “no-store”);
res.setDateHeader(“Expires”, 0);
res.setHeader(“Pragma”, “no-cache”);
System.out.println(“用户没有登陆，不允许操作”);
return;
} else {
chain.doFilter(request, response);
System.out.println(“用户已经登陆，允许操作”);
}
}
public void destroy() {
}
}
過濾器在web.xml
<filter-name>onlineFilter</filter-name>
<filter-class>filter.OnlineFilter</filter-class>
<!–
<init-param>
<param-name>exceptUrl</param-name>
<param-value>index.jsp</param-value>
</init-param>
–>
</filter>
<filter-mapping>
<filter-name>onlineFilter</filter-name>
<url-pattern>/reportJsp/*</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>onlineFilter</filter-name>
<url-pattern>/jsp/*</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>onlineFilter</filter-name>
<url-pattern>/reportServlet</url-pattern>
</filter-mapping>
7.通过获取的权限最终达到数据的完整交互 index.jsp部分代码：
<%
String realPath = “http://”
+ request.getServerName()
+ “:”
+ request.getServerPort()
+ request.getContextPath()
+ request.getServletPath().substring(0,
request.getServletPath().lastIndexOf(“/”) + 1);
String fullfilePath = realPath + “reportJsp/showReport.jsp?raq=”
+ raq;
System.out.println(“fullfilePath:” + fullfilePath);
response.sendRedirect(fullfilePath);
%>
优点：1.权限安全系数更高，只保证当前用户有权限操作，防止了部分通过新开IE记住URL的方式访问，包括
想通过查看源文件里对servlet的处理等，
2.权限的配置，操作完全交给.net系统处理,对报表的应用只要告诉我有没有权限执行当前的操作，要用的报
表，当前的用户信息即可，通用性好，耦合度低，易于集成
缺点：由于是跨语言，跨服务器集成操作,多多少少网络可能会阻止一些访问效率和响应时间等
难点：对WebServices代码的操作过程…
