Struts2施用@ParentPackage Unable to locate parent package [test] - [unknown l

Struts2使用@ParentPackage Unable to locate parent package [test] - [unknown l

? 今天遇到一个问题我在使用struts2的annotation的@ParentPackage注解的时候，报错：

Caused by: Unable to locate parent package [test] - [unknown location]

struts.xml配置：

<struts>
		<constant name="struts.devModel" value="true"></constant>
		<constant name="struts.i18n.encoding" value="UTF-8"></constant>
		
		<!-- <package name="test" extends="struts-default">
			<action name="TestAction" class="test">
				<result name="SUCCESS">${location}</result>
			</action>
		</package> -->
		<package name="test" extends="strust-default" namespace="/test" />
	</struts>

?java代码：

@Scope("prototype")
@Controller("testAction")
@ParentPackage("test")
public class TestAction extends DefaultAction {
    //~ Instance fields ----------------------------------------

    private BaseDAO baseDAO;

    //~ Methods ------------------------------------------------

    /**
     * test
     *
     * @return String
     */
    @Action(value="/execute" , results = {
    		@Result(name = "SUCCESS", location="/success.jsp")
    })
    public String execute() {
        System.out.println("test");

        return SUCCESS;
    }

    /**
     * add test
     *
     * @return
     */
    @Action(value = "/add" , results = {
    		@Result(name = "SUCCESS" , location = "/success.jsp")
    })
    public String add() {
    	getBaseDAO().add(null);
    	
        return SUCCESS;
    }

    /**
     * getter of baseDAO
     *
     * @return the baseDAO
     */
    public BaseDAO getBaseDAO() {
    	if (baseDAO == null){
    		this.baseDAO = (BaseDAO) ApplicationContextUtils.getBean("baseDAO");
    	}
        return baseDAO;
    }
}

结果搞了半天没有搞定， 后来我在struts.xml定义package时extends属性改为strust-default,json-default就不报错了

<struts>
		<constant name="struts.devModel" value="true"></constant>
		<constant name="struts.i18n.encoding" value="UTF-8"></constant>
		
		<package name="test" extends="strust-default,json-default" namespace="/test" />
	</struts>
