Spring MVC アプリケーションからの JSP 出力の装飾を制御するために、Sitemesh 3 を使用しようとしています。
アプリケーションを起動すると、Sitemesh が Spring サーブレットにリクエストを送信して、デコレータ ファイルを取得しようとしているようです。これは正しい動作である場合とそうでない場合がありますが、多くの頭痛の種になっています。
Sitemesh 3 についての私の理解では、Spring の後、つまり Response オブジェクトで機能するということです。
ブラウザーに表示されるエラーは 404 で、ログには次のように表示されます (構成/コードは次のとおりです)。

web.xml と、マッピング (URL) の定義方法に問題があると思われます。

私のカスタムフィルター:
public class SitemeshFilter extends ConfigurableSiteMeshFilter {
private Logger log = LoggerFactory.getLogger(SitemeshFilter.class);
/**
* See http://wiki.sitemesh.org/display/sitemesh3/Configuring+SiteMesh+3
*/
@Override
protected void applyCustomConfiguration(SiteMeshFilterBuilder builder) {
log.debug("** hit the sitemesh filter");
// apply this decorator (template) to the path defined...
builder.addDecoratorPath("/*", "/WEB-INF/decorators/mainDecorator.html");
// ... when the response type matches one of these
builder.setMimeTypes("text/html", "application/xhtml+xml", "application/vnd.wap.xhtml+xml");
} }
WEB-INF/ |-jsp |-home.jsp |-decorators |-mainDecorator.html
そして、私の超単純なコントローラー:
@RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Locale locale, Model model) {
logger.info("Welcome home! The client locale is {}.", locale);
Date date = new Date();
DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);
String formattedDate = dateFormat.format(date);
model.addAttribute("serverTime", formattedDate );
return "home";
}
