SiteMesh3配置

SiteMesh3 支持两种主要的配置： XML 和 Java，甚至两者可以共用。

 

XML	Java
容易上手 配置更改时可以自动重载 不需要懂得java编程	更灵活的制定  不需要多余的配置文件 可以使用JRuby, Groovy, Scala等语言配置

 

 

 

基于xml的配置

配置文件需放置于/WEB-INF/sitemesh3.xml ，如

<sitemesh>
  <mapping path="/*" decorator="/decorator.html"/>
  <mapping path="/admin/*" decorator="/admin-decorator.html"/>
</sitemesh>

<sitemesh>

  <mapping path="/*" decorator="/decorator.html"/>

  <mapping path="/admin/*" decorator="/admin-decorator.html"/>

</sitemesh>

 

 

 

基于java的配置

必须编写一个过滤器，继承org.sitemesh.config.ConfigurableSiteMeshFilter 且重载applyCustomConfiguration方法，如

public class MySiteMeshFilter extends ConfigurableSiteMeshFilter {
  @Override
  protected void applyCustomConfiguration(SiteMeshFilterBuilder builder) {
    builder.addDecoratorPath("/*", "/decorator.html")
           .addDecoratorPath("/admin/*", "/admin/decorator.html");
  }
}

public class MySiteMeshFilter extends ConfigurableSiteMeshFilter {

  @Override

  protected void applyCustomConfiguration(SiteMeshFilterBuilder builder) {

    builder.addDecoratorPath("/*", "/decorator.html")

           .addDecoratorPath("/admin/*", "/admin/decorator.html");

  }

}

 

 

如果xml和java两个配置方法共用，sitemesh3在调用applyCustomConfiguration()方法前会先加载xml的配置。

 

 

配置渲染

• 给所有路径配置一个默认的渲染
• 给特殊的路径配置一个渲染
• 给某个路径配置多个渲染，一个渲染依赖于前面的渲染
• 排除某个路径

xml

<sitemesh>

  <!-- 配置默认的渲染器. 将应用于所有路径. -->
  <mapping decorator="/default-decorator.html"/>

  <!-- 配置特定路径的渲染器. -->
  <mapping path="/admin/*" decorator="/another-decorator.html"/>
  <mapping path="/*.special.jsp" decorator="/special-decorator.html"/>

  <!-- 配置多个渲染器. -->
  <mapping>
    <path>/articles/*</path>
    <decorator>/decorators/article.html</decorator>
    <decorator>/decorators/two-page-layout.html</decorator>
    <decorator>/decorators/common.html</decorator>
  </mapping>

  <!-- 不被渲染的路径. -->
  <mapping path="/javadoc/*" exclue="true"/>
  <mapping path="/brochures/*" exclue="true"/>

</sitemesh>

<sitemesh>



  <!-- 配置默认的渲染器. 将应用于所有路径. -->

  <mapping decorator="/default-decorator.html"/>



  <!-- 配置特定路径的渲染器. -->

  <mapping path="/admin/*" decorator="/another-decorator.html"/>

  <mapping path="/*.special.jsp" decorator="/special-decorator.html"/>



  <!-- 配置多个渲染器. -->

  <mapping>

    <path>/articles/*</path>

    <decorator>/decorators/article.html</decorator>

    <decorator>/decorators/two-page-layout.html</decorator>

    <decorator>/decorators/common.html</decorator>

  </mapping>



  <!-- 不被渲染的路径. -->

  <mapping path="/javadoc/*" exclue="true"/>

  <mapping path="/brochures/*" exclue="true"/>
