在进行MVC+DAO实现分页的时候碰到了这个异常:
严重: Servlet.service() for servlet PersonServlet threw exception org.apache.jasper.JasperException: /person10.jsp(35,41) Attribute value request.getAttribute("lineSize") is quoted with " which must be escaped when used within the value at org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:40) at org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:407) at org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:198) at org.apache.jasper.compiler.Parser.parseQuoted(Parser.java:302) at org.apache.jasper.compiler.Parser.parseAttributeValue(Parser.java:249) at org.apache.jasper.compiler.Parser.parseAttribute(Parser.java:210) at org.apache.jasper.compiler.Parser.parseAttributes(Parser.java:148) at org.apache.jasper.compiler.Parser.parseParam(Parser.java:870) at org.apache.jasper.compiler.Parser.parseBody(Parser.java:1819) at org.apache.jasper.compiler.Parser.parseOptionalBody(Parser.java:1076) at org.apache.jasper.compiler.Parser.parseInclude(Parser.java:904) at org.apache.jasper.compiler.Parser.parseStandardAction(Parser.java:1227) at org.apache.jasper.compiler.Parser.parseElements(Parser.java:1578) at org.apache.jasper.compiler.Parser.parse(Parser.java:130) at org.apache.jasper.compiler.ParserController.doParse(ParserController.java:245) at org.apache.jasper.compiler.ParserController.parse(ParserController.java:101) at org.apache.jasper.compiler.Compiler.generateJava(Compiler.java:176) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:317) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:298) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:286) at org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:564) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:302) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:329) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:265) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:679) at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:461) at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:399) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:301) at com.tangjian.servlet.PersonServlet.doGet(PersonServlet.java:91) at javax.servlet.http.HttpServlet.service(HttpServlet.java:627) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:172) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:174) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:873) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:665) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:528) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:81) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Thread.java:595)
出现错误部分代码是
<jsp:include page="person_com.jsp"> <jsp:param name="jspUrl" value="<%=jspUrl %>"/> <jsp:param name="lineSize" value="<%=request.getAttribute("lineSize") %>"/> <jsp:param name="currentPage" value="<%=request.getAttribute("currentPage") %>"/> <jsp:param name="allRecoders" value="<%=request.getAttribute("allRecoders") %>"/> <jsp:param name="keyWord" value="<%=request.getAttribute("keyWord") %>"/> <jsp:param name="searchFlag" value="T"/> </jsp:include>
搜索了下,在csdn中的
http://blog.csdn.net/qzj5851/archive/2009/08/12/4437493.aspx
中发现了相同的问题。按照他的解决方法修改如下:
<jsp:include page="person_com.jsp"> <jsp:param name="jspUrl" value="<%=jspUrl %>"/> <jsp:param name="lineSize" value='<%=request.getAttribute("lineSize") %>'/> <jsp:param name="currentPage" value='<%=request.getAttribute("currentPage") %>'/> <jsp:param name="allRecoders" value='<%=request.getAttribute("allRecoders") %>'/> <jsp:param name="keyWord" value='<%=request.getAttribute("keyWord") %>'/> <jsp:param name="searchFlag" value="T"/> </jsp:include>
就是把value=""改成value=''。
问题是解决了,但是看他里面说是tomcat6.0版本的问题,可是我使用的是tomcat5.5的版本也出现这个问题。
我这个项目是使用到了servlet的,我还有一个是使用JSP+DAO实现分页的项目。在那个项目里面同样的代码就没有出现过这个问题。
自己现在猜测是tomcat解析servlet时候出现的一个问题。留待有时间的时候再来解决。
