struts2 的action 会执行两次

小弟在做网站的时候遇到action会被执行两次的情况，在网上找了资料，也没能解决。
首先我在index的页面写了一个链接

<a href="Employees/EmployeesPage">123</a>

这个页面跳转到EmployeesPage这个action
代码如下

<action name="EmployeesPage" class="com.lsxy.action.EmployeesAction" method="go">

	<result name="addPage">/EmployeesAddPage.jsp</result> 

</action>

method go的方法如下：

public String go() {

		QsCtypeDao ctypeDao = new QsCtypeDao();

		ctype = ctypeDao.findAll();

		System.out.println("123");

		return "addPage";

	}

输出的时候 控制台有2个123 并有警告。

123
