Question

以下是我的情况：

我在Eclipse中有一个Web应用程序。目前它是一个AspectJ Web应用程序。

我的“src”文件夹中有一个名为JSPCSRFTokenInjection.aj的方面，它具有捕获JspWriter.write方法和其他一些东西的切入点。它看起来像这样：

package com.aspects; 
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.jsp.JspWriter;

import org.apache.log4j.Logger;

import com.thesis.aop.util.StopWatch;

public aspect JSPCSRFTokenInjection{ 
Logger logger; 
StopWatch watch;

private String currentCSRFToken = null;

//Constuctor for the Aspect. I do some init of loggers and
//such here.
public JSPCSRFTokenInjection(){ 
    //PropertyConfigurator.configure("log4j.properties"); 
    logger = Logger.getLogger("csrfMitigationLogger"); 
    logger.info("CSRF Injection Aspect Created"); 
    watch = new StopWatch(); 
} 


//Capturing the CSRF Token from the request by intercepting the 
//_jspService method inside of the JSP
public pointcut csrf_jspServiceIntercept(HttpServletRequest req, 
    HttpServletResponse resp) : 
    call(public void _jspService(HttpServletRequest, HttpServletResponse)) 
    && args(req, resp);


before(HttpServletRequest req, HttpServletResponse resp) : 
    csrf_jspServiceIntercept(req, resp){
    currentCSRFToken = (String) req.getParameter("csrfSalt");
    logger.info("Got CSRF Token from request: " + currentCSRFToken);
}

//Pointcut and advice for capturing the writing into a JSP.
public pointcut csrf_captureFormWriting(String msg, JspWriter writer) :
    call(public void JspWriter.write(String)) 
    && args(msg) 
    && target(writer)
    && if(msg.toLowerCase().contains("</form>"));

before(String msg, JspWriter writer) : csrf_captureFormWriting(msg, writer){
    try{
        logger.info("WRITING TO JSP");
        writer.write("TEST_CSRF");
        writer.write("<input type='hidden' name='csrfSalt' value='" +     currentCSRFToken + "'/>");
    }
    catch(Exception e){
        e.printStackTrace();
    }
}

}

我在aop.xml目录中也有一个WebApp/WebContent/META-INF/文件。作为参考，我的web.xml文件位于WebApp/WebContent/WEB-INF/目录中。

aop.xml看起来像这样：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE aspectj PUBLIC "-//AspectJ//DTD//EN" "http://www.eclipse.org/aspectj       /dtd/aspectj.dtd">
<aspectj>
<weaver options="-showWeaveInfo -verbose -debug -Xset:weaveJavaPackages=true">
    <!-- Weave types that are within the javax.* or org.aspectj.*
    packages. Also weave all types in the foo package that do
    not have the @NoWeave annotation. -->
    <include within="javax.*"/>
    <include within="com.*"/>
    <include within="org.*"/>
    <include within="org.aspectj.*"/>
</weaver>
<aspects>
    <!-- declare two existing aspects to the weaver -->
    <aspect name="com.aspects.JSPCSRFTokenInjection"/>
    <aspect name="com.aspects.MitigateCSRFAspect"/>
    <!-- Of the set of aspects declared to the weaver
    use aspects matching the type pattern "com..*" for weaving. -->
    <include within="com.*"/>
    <include within="org.*"/>
    <!-- Of the set of aspects declared to the weaver
    do not use any aspects with the @CoolAspect annotation for weaving -->
</aspects>
</aspectj>

我还在Tomcat中将-javaagent:C:/aspectj1.6/lib/aspectjweaver.jar添加到我的JVM参数中。

如果有帮助，我正在使用tomcat的SysDeo插件。此外，编译时编织在应用程序的其他部分工作正常，但是，我无法编织影响JSP的任何方面。

我弄明白了这个问题。我把我的aop.xml文件放在错误的目录中。对我来说非常愚蠢。

应该进入

<ProjectRoot>/WebContent/WEB-INF/classes/META-INF/aop-ajc.xml

目录。但是，我把它直接放在WEB-INF下。

如何使用AspectJ 1.6和Tomcat 6加载JSP的时间编织？
