Zk 在 zul 中包含 richlet

Question

我创建了一个 richlet java class 并在 zk.xml 中链接并且它工作正常。现在我试图将此 richlet 包含在一个简单的 zul 页面中，但出现错误。

<zk xmlns:w="client" xmlns:n="native">
    <window>
  <include src="/zk/testdebug" mode="instant"/> <!-- creates another page -->
</window>
</zk>

这是我的日志错误

Answer 1

这就是我在 web.xml

中映射 zkLoader 的方式

<servlet-mapping>
    <servlet-name>zkLoader</servlet-name>
    <url-pattern>/zk/*</url-pattern>
</servlet-mapping>

所以我尝试删除主路径“/zk”，现在我可以像那样包含我的 richlet

<zk xmlns:w="client" xmlns:n="native">
    <window>
  <include src="/testdebug" mode="instant"/> <!-- creates another page -->
</window>
</zk>

而且效果很好。

Zk 在 zul 中包含 richlet

Zk include richlet in zul

java

zk
