Struts2 action 异常处理

异常类：需要继承exception类

<span style="font-size:14px;">package org.senssic.exception; 
 
public class MyEeption extends Exception { 
	private static final long serialVersionUID = 1L; 
 
	public MyEeption(String msg) { 
		super(msg); 
	} 
}</span> 

action类：

<span style="font-size:14px;">package org.senssic.action; 
 
import org.senssic.exception.MyEeption; 
 
public class EAction { 
 
	public String execute() throws Exception { 
		int i = 5; 
		if (i > 4) { 
			throw new MyEeption("你的数字大于5啦啦啦"); 
		} 
		return "success"; 
	} 
} 
</span>
