Spring boot + taglibs + java.util.NoSuchElementException

时间：2015-03-05 10:39:59

标签： spring-boot taglib apache-tiles

我正在使用带有web mvc磁贴的Spring Boot。还使用Bootsrap CSS作为前端

我有一个名为basic.jsp的主布局页面为

<%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles"%>
 <html>
  <head>
    <title><tiles:getAsString name="title" /></title>
  </head>
 <body>
    <!-- Header -->
    <tiles:insertAttribute name="header" />
    <!-- Body -->
    <tiles:insertAttribute name="body" />
    <!-- Footer -->
    <tiles:insertAttribute name="footer" />
 </body>
 </html>

和tiles.xml 

<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE tiles-definitions PUBLIC
   "-//Apache Software Foundation//DTD Tiles Configuration 3.0//EN"
   "http://tiles.apache.org/dtds/tiles-config_3_0.dtd">
<tiles-definitions>

<!-- Templates -->

<definition name="layout.basic" template="/pages/layout/basic.jsp">
    <put-attribute name="header" value="/pages/jsps/header.jsp" />
    <put-attribute name="leftmenu" value="/pages/jsps/lmenu.jsp" />
    <put-attribute name="body" value="" />
    <put-attribute name="footer" value="/pages/jsps/footer.jsp" />
</definition>

<!-- Pages -->  

<definition name="home" extends="layout.basic">
    <put-attribute name="body" value="/WEB-INF/tiles/view/home/home.jsp" />
</definition>

<definition name="greet" extends="layout.basic">
    <put-attribute name="body" value="/WEB-INF/tiles/view/home/register.jsp"                                                                         />
</definition>

</tiles-definitions>

我想将spring form taglib包含在register.jsp

中 
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<div>
 <div class="col-md-9 personal-info">

   <form:form method="POST" id="frm" class="form-horizontal" role="form"         commandName="box" action="Register">

      <div class="form-group">
        <label class="col-lg-3 control-label">Box Id:</label>
        <div class="col-lg-8">
          <form:input class="form-control" path="strBoxId" type="text"         placeholder="Box Id"></form:input>
        </div>
      </div>
      <div class="form-group">
        <label class="col-lg-3 control-label">Box Name:</label>
        <div class="col-lg-8">
          <form:input class="form-control" type="text" path="strBoxName"      value="" placeholder="Box Name"></form:input>
        </div>
      </div>          
       <div class="form-group">
        <label class="col-lg-3 control-label">Address:</label>
        <div class="col-lg-8">
          <form:textarea class="form-control" placeholder="Address"      path="strAddress"></form:textarea>
        </div>
      </div>

       <div class="form-group">
        <label class="col-md-3 control-label"></label>
        <div class="col-md-8">
          <input type="submit" class="btn btn-primary" id="register"      value="Register" onclick="callMe()">
          <span></span>
          <input type="reset" class="btn btn-default" value="Cancel">
        </div>
      </div>
    </form:form>
  </div>
</div>

当我在不包含taglib的情况下运行应用程序时，它正在显示表单，但是当我在tag.jsp中包含taglib时，它会在cosole中抛出错误，并在浏览器中抛出Whitelabel错误页面。显示的错误是

2015-03-05 15:23:45.296 ERROR 8056 --- [nio-8080-exec-8] o.a.c.c.C.[. [localhost].[/].[jsp]        : Servlet.service() for servlet jsp threw exception
