BaseAction编写：免去一些重复的代码，比如继承ActionSupport和实现ModelDriven接口

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<T> extends ActionSupport implements ModelDriven<T>{

    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);;
        
    }
    
}
