1、Struts2的web.xml的配置问题
这个问题是因为你的web.xml过滤器配置的问题
如果你的过滤器配置的是*.action的话,就只能通过后台代码访问jsp页面
例: <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping>
因为如果不通过action而直接访问jsp页面的话,Struts2标签在解析的时候会获取当前线程ThreadLocal中的Dispatcher。而Dispatcher是在Struts过滤器中预设的。
代码如下: Java代码 public static ValueStack getStack(PageContext pageContext) { HttpServletRequest req = (HttpServletRequest) pageContext.getRequest(); ValueStack stack = (ValueStack) req.getAttribute(ServletActionContext.STRUTS_VALUESTACK_KEY); if (stack == null) { HttpServletResponse res = (HttpServletResponse) pageContext.getResponse(); Dispatcher du = Dispatcher.getInstance(); if (du == null) { throw new ConfigurationException("The Struts dispatcher cannot be found. This is usually caused by "+ "using Struts tags without the associated filter. Struts tags are only usable when the request "+ "has passed through its servlet filter, which initializes the Struts dispatcher needed for this tag."); }
2、hibernate sql语句表名后面多了一个;号
解决办法是检查你的实体类配置文件
table属性表名后面的;号删除就可以了
