我的应用程序的某些页面运行得很好。但接下来我们来看看这段代码：
<s:form id="filter" action="./filtro_BuscaAdm.html" validate="false">
<s:hidden key="newFiltro" value="true"/>
<s:textfield id="buscaGen" key="campoBusca" />
<input type="text" name="x" class="displayNone"/>
<s:submit onclick="return validarBusca();" label="Filtrar" targets="dados"
value="Filtrar" type="image" src="../images/searchButton.png" "/>
</s:form>
呈现此页面时会出现以下异常：
错误ClosingUIBean无法打开模板 java.lang.NullPointerException at org.apache.struts2.components.ServletUrlRenderer.renderFormUrl（ServletUrlRenderer.java:135） 在 org.apache.struts2.components.Form.populateComponentHtmlId（Form.java:232） 在 org.apache.struts2.components.UIBean.evaluateParams（UIBean.java:816） 在 org.apache.struts2.components.ClosingUIBean.start（ClosingUIBean.java:55） 在 org.apache.struts2.views.jsp.ComponentTagSupport.doStartTag（ComponentTagSupport.java:54） 在 org.apache.jsp.decorators.default_jsp._jspx_meth_s_005fform_005f0（default_jsp.java:1483） 在 org.apache.jsp.decorators.default_jsp._jspService（default_jsp.java:326）
和
java.lang.NullPointerException at org.apache.struts2.components.UIBean.evaluateParams（UIBean.java:824） 在org.apache.struts2.components.UIBean.end（UIBean.java:535）at org.apache.struts2.views.jsp.ComponentTagSupport.doEndTag（ComponentTagSupport.java:42） 在 org.apache.jsp.decorators.default_jsp._jspx_meth_s_005fhidden_005f0（default_jsp.java:1542） 在 org.apache.jsp.decorators.default_jsp._jspx_meth_s_005fform_005f0（default_jsp.java:1493）
如果我将<s:form>更改为<form>，则会正常呈现
在其他页面中，<s:form>代码正常呈现
我已经好几个星期了。我们使用maven来解决依赖关系
这是我一直在用我的发现写作的一步一步：
更改pom中的jar版本（duh）
不推荐使用ActionContextCleanUp过滤器。将其删除
FilterDispatcher现在是StrutsPrepareAndExecuteFilter
更新commons-lang，commons-fileupload，删除xwork和ognl jars
相应地更改struts.xml（拦截器名称和标头版本声明）
在这些步骤之后，我能够在没有构建错误的情况下部署应用程序。然后我跑了几个jsp erros并且一个接一个地解决它们。到目前为止，我发现了：
<s:>内的<form>标记会触发＆＃34; freemarker＆＃34;例外。 ＆＃34; S＆＃34;标签只允许在＆＃34; S＆＃34;部件
其他信息：
Javax.servlet版本是2.4
我可以将xwork jar添加到类路径中。没什么区别。但我认为我不应该添加它，因为它的核心包含在struts-2.5-core.jar
中我已经浏览了apache.org迁移指南和stackoverflow，但无法找到与此相关的任何内容
这是web.xml文件，已满。 ＆＃34; BrainwebFilterDispatcher＆＃34; Filter扩展了StrutsPrepareAndExecuteFilter
