1.BaseAction

package com.learning.crm.base;

import java.lang.reflect.ParameterizedType;

import java.lang.reflect.Type;

import com.opensymphony.xwork2.ActionContext;

import com.opensymphony.xwork2.ActionSupport;

import com.opensymphony.xwork2.ModelDriven;

public class BaseAction extends ActionSupport implements ModelDriven{

private T t;//必须进行实例化

private Class clazz;

//初始化得到T

public BaseAction() throws Exception {

super();

ParameterizedType parameterizedType= (ParameterizedType) this.getClass().getGenericSuperclass();

clazz= (Class) parameterizedType.getActualTypeArguments()[0];

t=(T) clazz.newInstance();

}

@Override

public T getModel() {

return t;

}

//...这里省略service注入；；

//一些共有的操作

/**

* 1.压栈

* @param object

*/

public void push(Object object) {

ActionContext.getContext().getValueStack().push(object);;

}

/**

* 2.存入actionContext

* @param key

* @param object

*/

public void put(String key,Object object) {

ActionContext.getContext().put(key,object);;

}

}

2.使用时只需继承BaseAction
