如何将 Tiles 3 与 Struts2 正确集成？

Question

我正在尝试将 Tiles 3 与 Struts2 集成。

我想我已经在库中添加了所有必要的 jar 文件，但我得到：

java.lang.ClassNotFoundException: org.apache.struts2.tiles.StrutsTilesListener

Answer 1

您似乎错过了类路径中的 struts2-tiles-plugin.jar。添加它，错误应该消失了。

Answer 2

我猜你错过了 jar/dependency，它有 org.apache.struts2.tiles.StrutsTilesListener class，也就是 struts2-tiles-plugin jar。看看 search.maven.org

如果要下载 jar，请从同一个 link 下载。

如果您使用的是 maven，请添加此依赖项。

<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-tiles-plugin</artifactId>
    <version>2.5-BETA1</version>
</dependency>

Answer 3

要将 Tiles 3 与 Struts 2 集成，您需要使用 struts2-tiles3-plugin, not the struts2-tiles-plugin.

您正在使用 Tiles2 侦听器:

<listener-class>
    org.apache.struts2.tiles.StrutsTilesListener
</listener-class>

右边的是Tiles3 Listener:

<listener-class>
    org.apache.tiles.extras.complete.CompleteAutoloadTilesListener
</listener-class>

你也用错了Struts2过滤器:

<filter-class>
    org.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter
</filter-class>

使用完整的：

<filter-class>
    org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
