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JDK与目前的JDKJDK不兼容例如其中的配置如下
The following assumes you are using JDK 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 ResourceSecurityxml
policy files with the correct path names
) Copy the jaasjar and the jaasmodjar to your JDK jre\lib\ext directory
(ie D:\JDK\jre\lib\ext)
) Add the following to the end of the javasecurity file located in JDKs
jre\lib\security directory (ie D:\JDK\jre\lib\security):
authpolicyprovider=comibmresourcesecurityauthXMLPolicyFile
) Execute the runbat file
以后为policyprovider=PolicyFile而且需要修改javasecurity文件
我经过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
welcomejsp indexjsp strutsconfigxml
<%@ taglib uri=/tags/strutslogic prefix=logic %>
<logic:redirect forward=index/>
<% welcomejspRedirect default requests to Welcome global ActionForwardBy using a redirect the useragent will change address to match the path of our Welcome ActionForward %>
indexjsp
<%@ page contentType=text/html; charset=UTF%>
<%@ taglib uri=/tags/strutsbean prefix=bean%>
<%@ taglib uri=/tags/strutshtml prefix=html%>
<%@ taglib uri=/tags/strutslogic prefix=logic%>
<html:html>
<Title>Logon
</Title>
<body><html:form action=/LoginActiondo>
<p>User ID:
<input type=text name=userID value=tyrone />
<br>
Passord: <input type=password name=password value=password/>
<br>
<html:submit />
</p>
</html:form>
</body>
</html:html>
strutsconfigxml
<?xml version= encoding=ISO ?>

实现limaswebactionStartupServlet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
//LoggerFactorysetFactory(new EPricerLogFactory ());
// (this Startup of Settings application);
initJAAS();return mappingfindForward(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nfig文件地址
SystemsetProperty(javasecnfigJAASConstantsAUTH_SECURITY_LOGINFILE);
}
}
public interface JAASConstants {
String AUTH_SECURITY_POLICYXMLFILE=D:\\MyProject\\colimas\\clmsweb\\colimas\\securitypolicyxml;
String AUTH_SECURITY_LOGINFILE=D:\\MyProject\\colimas\\clmsweb\\colimas\\nfig;
String AUTH_SECURITY_MODULENAME=ColimasLogin;}
nfig文件内容
ColimasLogin
{
limassecurityauthColimasLoginModule required debug=true;
};
实现ColimasLoginModule登录模块
