struts 配置文件中定义的不同包的全局结果

global results across different packages defined in struts configuration file(struts 配置文件中定义的不同包的全局结果)

问题描述

我想在不同命名空间下的不同包中创建一个 global-results.我可以知道 struts 配置文件中需要遵循的约定吗?

I would like to create a global-results across different packages which are under different namespaces. Can I know the conventions that required to follow in struts config file?

推荐答案

在其他包扩展的包中定义全局结果.例如

Define global result in the package that other packages extend. For example

<package name="default" extends="struts-default">
  ...
  <global-results>
    <result name="error">/pages/error_page.jsp</result>
  </global-results>
  ...
</package>

此结果可用于转发到错误页面的操作并作为异常处理结果.

This result could be used across actions that forward to error page and as exception handling result.

如果您使用带有注释的约定插件，您可以在具有其他包扩展的父包的类上定义 @Results 注释.例如

If you are using conventions plugin with annotations you could define @Results annotation on the class that has the parent package other packages extend. For example

@Results({
  @Result(name = ERROR, location = "/pages/error_page.jsp"),
})

父包使用 @ParentPackage 注释进行注释.它可以放在类上，但最好放在包上.例如

The parent package is annotated with @ParentPackage annotation. It could be placed on the class but better place it on the package. For example

package-info.java:

@ParentPackage("default")
