Bug报告地址: http://jira.opensymphony.com/browse/SIM-127

Bug描述: 在和sitemesh和struts整合使用时, 由于request.getRequestURI()得到的是请求的路径(浏览器地址栏输入的路径), 而通过request.getPathInfo()得到的确实配置的实际页面的路径, 因此, 根据sitemesh的com.opensymphony.module.sitemesh.mapper.ConfigDecoratorMapper.getDecorator(HttpServletRequest, Page)这个方法的处理不能得到有效的装饰器配置.

涉及源代码:

public Decorator getDecorator(HttpServletRequest request, Page page) { String thisPath = request.getServletPath(); // getServletPath() returns null unless the mapping corresponds to a servlet if (thisPath == null) { String requestURI = request.getRequestURI(); if (request.getPathInfo() != null) { // strip the pathInfo from the requestURI thisPath = requestURI.substring(0, requestURI.indexOf(request.getPathInfo())); } else { thisPath = requestURI; } } String name = null; try { name = configLoader.getMappedName(thisPath); } catch (ServletException e) { e.printStackTrace(); } Decorator result = getNamedDecorator(request, name); return result == null ? super.getDecorator(request, page) : result; }

处理方案(此种解决方案经过测试在使用一级目录配置装饰器的时候工作良好.):

public Decorator getDecorator(HttpServletRequest request, Page page) {String thisPath = request.getServletPath();// getServletPath() returns null unless the mapping corresponds to a// servletif (thisPath == null) {String requestURI = request.getRequestURI();if (request.getPathInfo() != null) {// strip the pathInfo from the requestURIthisPath = requestURI.substring(0, requestURI.indexOf(request.getPathInfo()));} else {thisPath = requestURI;}} else {thisPath = request.getRequestURI();}String name = null;try {name = configLoader.getMappedName(thisPath);} catch (ServletException e) {e.printStackTrace();}Decorator result = getNamedDecorator(request, name);return result == null ? super.getDecorator(request, page) : result;}
