@Action(value = "default",results = {
    @Result(name = "success",type="tiles",location = "login") })
public String defaultAction() {
    return SUCCESS;
}

当我调用proxy.execute()时,测试崩溃了.我可能忘记了
让我的测试用瓷砖运行的东西,但我不知道它可能是什么.
我得到以下堆栈跟踪：

java.lang.NullPointerException
at org.apache.struts2.views.tiles.TilesResult.doExecute(TilesResult.java:105)
at org.apache.struts2.dispatcher.StrutsResultSupport.execute(StrutsResultSupport.java:186)
at com.opensymphony.xwork2.DefaultActionInvocation.executeResult(DefaultActionInvocation.java:373)
...

当我更改下面的操作时,测试正常执行：

@Action(value = "default",type="redirectAction",location = "login") })
public String defaultAction() {
    return SUCCESS;
}
