struts2根据action中的方法参数值来动态调用方法
struts2 根据action中的方法参数值来动态调用方法,例如http://localhost:8080/login.do?method=dynamicMethod
根据method参数来调用action中的dynamicMethod方法，主要是自定义拦截器来实现，代码如下
package com.tedonl.interceptor;import javax.servlet.http.HttpServletRequest;import org.apache.struts2.ServletActionContext;import com.opensymphony.xwork2.ActionInvocation;import com.opensymphony.xwork2.interceptor.AbstractInterceptor;public class DynamicMethodInterceptor extends AbstractInterceptor {private static final long serialVersionUID = -2341874790105032740L;@Overridepublic String intercept(ActionInvocation invocation) throws Exception {HttpServletRequest request = ServletActionContext.getRequest();String myMehtod = request.getParameter("mehtod");if (myMehtod != null) {try {java.lang.reflect.Method method = invocation.getAction().getClass().getMethod(myMehtod);String result = (String) method.invoke(invocation.getAction());if (result != null) {return result;} else {return null;}} catch (Exception e) {e.printStackTrace();}}return invocation.invoke();}}?然后在web.xml中配置上自己的拦截器即可
