本篇文章主要介绍了" jsp中sitemesh修改tagRule技术分享"，主要涉及到方面的内容，对于JSPjrs看球网直播吧_低调看直播体育app软件下载_低调看体育直播感兴趣的同学可以参考一下：

sitemesh默认提供了一些常用的rule
可以看到其实可以选择
/**
* Extracts the contents of any elements that look like
* ... and write the contents
* to a page property (page.foo).
*
* This is a cheap and cheerful mechanism for embedding multiple components in a
* page that can be used in different places in decorators.

public class ContentBlockExtractingRule extends BasicBlockRule {
private final ContentProperty propertyToExport;
public ContentBlockExtractingRule(ContentProperty propertyToExport) {
this.propertyToExport = propertyToExport;
}
@Override
protected String processStart(Tag tag) throws IOException {
tagProcessorContext.pushBuffer();
return tag.getAttributeValue("tag", false);
}
@Override
protected void processEnd(Tag tag, String tagId) throws IOException {
propertyToExport.getChild(tagId).setValue(tagProcessorContext.currentBufferContents());
tagProcessorContext.popBuffer();
}
}
修改ScriptTagRuleBundle处理如下
public class ScriptTagRuleBundle implements TagRuleBundle {
@Override
public void install(State defaultState, ContentProperty contentProperty, SiteMeshContext siteMeshContext) {
defaultState.addRule("content", new ContentBlockExtractingRule(contentProperty.getChild("page")));
}
@Override
public void cleanUp(State defaultState, ContentProperty contentProperty, SiteMeshContext siteMeshContext) {
}
}用法很简单使用content作为tag默认填上tag即可
