struts2提供的接口ParameterAware怎么使用，哪里能查到具体用法，或者大侠们给个例子。

如题。提供文档或者例子都可以。

ParameterAware 是一接口，只提供了一个方法，如下：
void setParameters(Map parameters)
在别处给你找了个例子：
//重点：通过继承org.apache.struts2.interceptor包下的**Aware接口的set**注入

package com.teana.action;

import java.io.PrintWriter;
import java.util.Map;

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

import org.apache.struts2.interceptor.ApplicationAware;
import org.apache.struts2.interceptor.ParameterAware;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;
import org.apache.struts2.interceptor.SessionAware;

import com.opensymphony.xwork2.ActionSupport;

public class AwareAction extends ActionSupport implements ServletResponseAware,
ServletRequestAware, SessionAware, ApplicationAware, ParameterAware
{
private HttpServletResponse response;
private HttpServletRequest request;
private Map session;
private Map application;
private Map parameters;
@Override
public String execute() throws Exception
{
PrintWriter out = response.getWriter();
out.write(parameters.get("name"));
out.write("========================");
out.write((String)request.getAttribute("name"));

out.write(session.toString());
out.write(application.toString());
//
return SUCCESS;
}

public void setServletResponse(HttpServletResponse response)
{
this.response = response;
}

public void setServletRequest(HttpServletRequest request)
{
this.request = request;
}

@SuppressWarnings("unchecked")
public void setSession(Map session)
{
this.session = session;
}

@SuppressWarnings("unchecked")
public void setApplication(Map application)
{
this.application = application;
}

@SuppressWarnings("unchecked")
//其实就是个注入，没别的，就这样用
public void setParameters(Map parameters)
{
this.parameters = parameters;
}

}
一般用的话，就是通过这个注入parameters 然后再获取参数用的
