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] at org.apache.struts2.convention.PackageBasedActionConfigBuilder.getPackageConfig(PackageBasedActionConfigBuilder.java:951) at org.apache.struts2.convention.PackageBasedActionConfigBuilder.buildConfiguration(PackageBasedActionConfigBuilder.java:600) at org.apache.struts2.convention.PackageBasedActionConfigBuilder.buildActionConfigs(PackageBasedActionConfigBuilder.java:335) at org.apache.struts2.convention.ClasspathPackageProvider.loadPackages(ClasspathPackageProvider.java:53) at com.opensymphony.xwork2.config.impl.DefaultConfiguration.reloadContainer(DefaultConfiguration.java:215) at com.opensymphony.xwork2.config.ConfigurationManager.getConfiguration(ConfigurationManager.java:66) ... 22 more 

?

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" 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>
