Struts Web Security JSP Bean

JAAS参考资料中流行的文章是扩展JAAS实现类实例级授权

但它是基于JDK1.3，与目前的JDK1.4，JDK1.5不兼容，例如其中的配置如下：

The following assumes you are using JDK 1.3 and the files were extracted to

the d:\JaasExample directory. You will save some work by extracting the files

to this directory otherwise you will have to modify the policy and the ResourceSecurity.xml

policy files with the correct path names.

1) Copy the jaas.jar and the jaasmod.jar to your JDK jre\lib\ext directory

(i.e. D:\JDK1.3\jre\lib\ext).

2) Add the following to the end of the java.security file located in JDK's

jre\lib\security directory (i.e. D:\JDK1.3\jre\lib\security):

auth.policy.provider=com.ibm.resource.security.auth.XMLPolicyFile

3) Execute the run.bat file.

1.4以后为policy.provider=PolicyFile。而且需要修改java.security文件,而且不使用VM的-Djava.security.manager就不能使用XMLPolicyFile。

我经过2天的呕血奋战实现了不改变java VM环境和Web server环境，在struts下实现JAAS。

步骤如下：

1. welcome.jsp, index.jsp, struts-config.xml

<%@ taglib uri="/tags/struts-logic" prefix="logic" %>

<logic:redirect forward="index"/>

<%-- welcome.jsp

Redirect default requests to Welcome global ActionForward.

By using a redirect, the user-agent will change address to match the path of our Welcome ActionForward.

--%>

index.jsp

<%@ page contentType="text/html; charset=UTF-8"%>

<%@ taglib uri="/tags/struts-bean" prefix="bean"%>

<%@ taglib uri="/tags/struts-html" prefix="html"%>

<%@ taglib uri="/tags/struts-logic" prefix="logic"%>

<html:html>

<Title>Logon</Title>

<body>

<html:form action="/LoginAction.do">

Passord: <input type="password" name="password" value="password"/><br>

<html:submit /></p>

</html:form>

</body>

</html:html>

struts-config.xml

<?xml version="1.0" encoding="ISO-8859-1" ?>

<!DOCTYPE struts-config PUBLIC

"-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"

"http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd">

<struts-config>

<form-beans>

<form-bean

name="LoginForm"

type="com.nova.colimas.web.form.LoginForm"/>

</form-beans>

<global-forwards>

<forward

name="index"

path="/index.do"/>

</global-forwards>

<action-mappings>

<action path="/index"

type="com.nova.colimas.web.action.StartupServlet">

</action>

<action path="/LoginAction"

type="com.nova.colimas.web.action.LoginAction"

name="LoginForm"

scope="request"

input="/pages/indexcon.jsp"

validate="true">

</action>

</action-mappings>

</struts-config>

2. 实现com.nova.colimas.web.action.StartupServlet用来初始化JAAS需要的系统属性

public class StartupServlet extends Action {

public ActionForward execute(ActionMapping mapping,

ActionForm form,

HttpServletRequest request,

HttpServletResponse response)

throws Exception{

// Initialization of the log

//LoggerFactory.setFactory(new EPricerLogFactory ());

//Log.info (this, "Startup of Settings application");

initJAAS();

return mapping.findForward("success");

}

//初始化JAAS需要的系统属性

private void initJAAS(){

//set env variable

//用于认证JAASConstants接口内保存login.config文件地址 System.setProperty("java.security.auth.login.config",JAASConstants.AUTH_SECURITY_LOGINFILE);

}

public interface JAASConstants {

String AUTH_SECURITY_POLICYXMLFILE="D:\\MyProject\\colimas\\clms-web\\colimas\\security-policy.xml";

String AUTH_SECURITY_LOGINFILE="D:\\MyProject\\colimas\\clms-web\\colimas\\login.config";

String AUTH_SECURITY_MODULENAME="ColimasLogin";

}

ColimasLogin {

com.nova.colimas.security.auth.ColimasLoginModule required debug=true;

};

3.实现ColimasLoginModule登录模块

this.subject = subject;

this.callbackHandler = callbackHandler;

// initialize configuration options
