HDIV + Spring标签库（表格）=错误，可能的错误？(HDIV + Spring tag library (form) = Error, possible bug?)
我发现HDIV使用标签Spring元素：“<form：form>”时遇到了麻烦。
首先，我将解释我的应用程序的体系结构：我使用的是Spring framework 4.1.6，Spring Security 4.0.0和HDIV 2.1.10。
到目前为止，我在开发过程中没有错误，但是现在我在jsp文件中找到了一个，当我使用Spring的form标签时：
<form:form action="${pageContext.servletContext.contextPath}/newUser" method="POST" class="form-horizontal" commandName="user">我在第34行中获得了这个错误：“<form：form”
位于org.springframework.web.servlet.tags.form.FormTag.processAction（FormTag.java:479）的org.hdiv.web.servlet.support.HdivRequestDataValueProcessor.processAction（HdivRequestDataValueProcessor.java:122）中的java.lang.NullPointerException在org.springframework的org.springframework.web.servlets.tags.form.FormTag.writeTagContent(FormTag.java:349）中的org.springframework.web.servlet.tags.form.FormTag.resolveAction（FormTag.java:433）。 web.servlet.tags.form.AbstractFormTag.doStartTagInternal（AbstractFormTag.java:84）位于org.apache.jsp.WEB_002dINF.jsp的org.springframework.web.servlet.tags.RequestContextAwareTag.doStartTag（RequestContextAwareTag.java:80）。 newUser_jsp._jspx_meth_form_005fform_005f0（newUser_jsp.java:197）org.apache.jsp.WEB_002dINF.jsp.newUser_jsp._jspService(newUser_jsp.java:137）org.apache.jasper.runtime.HttpJspBase.service（HttpJspBase.java:70）在javax.servlet.http.HttpServlet.service（HttpServlet.java:729）
更多.....（如果有必要，我可以提供）
当我尝试相同的代码，但为标签“<form>”交换标签“<form：form>”它是有效的。
当我详细检查HDIV的代码时：
HdivRequestDataValueProcessor.class
public class HdivRequestDataValueProcessor implements RequestDataValueProcessor protected LinkUrlProcessor linkUrlProcessor; protected FormUrlProcessor formUrlProcessor; if (this.innerRequestDataValueProcessor != null) { String processedAction = this.innerRequestDataValueProcessor.processAction(request, action, method); if (processedAction != action) { action = processedAction; } } String result = this.formUrlProcessor.processUrl(request, action, method);//line 122 return result; }我想知道可能由于'form：form'与'form'结构不同，HDIV无法找到一些参数，如'action'，'method'......但我不确定。
我还附加了我的配置文件以提供更多有用的信息（基于Java的配置）：
WebApplicationInit.class
import javax.servlet.Filter; import javax.servlet.ServletContext; import org.hdiv.filter.ValidatorFilter; import org.hdiv.listener.InitListener; import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer; public class WebApplicationInit extends AbstractAnnotationConfigDispatcherServletInitializer { // http://www.robinhowlett.com/blog/2013/02/13/spring-app-migration-from-xml-to-java-based-config/ @Override protected Class<?>[] getRootConfigClasses() { return new Class[] { RootConfig.class, DatabaseConfig.class, SecurityConfig.class, HdivSecurityConfig.class }; // , HdivSecurityConfig.class } @Override protected Class<?>[] getServletConfigClasses() { return new Class[] { MvcConfig.class }; } @Override protected String[] getServletMappings() { return new String[] { "/" }; } //web.xml filter @Override protected Filter[] getServletFilters(){ return new Filter[] { new ValidatorFilter()}; } // web.xml listener @Override protected void registerDispatcherServlet(ServletContext servletContext) { super.registerDispatcherServlet(servletContext); servletContext.addListener(InitListener.class); } }HdivSecurityConfig.class

我改变了将HDIV添加到我的Web应用程序的方法，将其添加到xml文件中，而不是使用基于java的配置。 另外，我使用示例添加了限定符标记（MvcConfig.class），但是当我使用它时它不起作用...（它找不到bean ...）。 null错误并没有消失......
I'm finding troubles using HDIV with the tag Spring element: "< form:form >".
First, I'm going to explain the architecture of my application: I'm using Spring framework 4.1.6, Spring Security 4.0.0 and HDIV 2.1.10.
So far I'm not having errors during the development, nevertheless now I 've found one in a jsp file, when I'm using the form tag from Spring:
<form:form action="${pageContext.servletContext.contextPath}/newUser" method="POST" class="form-horizontal" commandName="user">I obtained this error in the line 34: "< form:form "
java.lang.NullPointerException at org.hdiv.web.servlet.support.HdivRequestDataValueProcessor.processAction(HdivRequestDataValueProcessor.java:122) at org.springframework.web.servlet.tags.form.FormTag.processAction(FormTag.java:479) at org.springframework.web.servlet.tags.form.FormTag.resolveAction(FormTag.java:433) at org.springframework.web.servlet.tags.form.FormTag.writeTagContent(FormTag.java:349) at org.springframework.web.servlet.tags.form.AbstractFormTag.doStartTagInternal(AbstractFormTag.java:84) at org.springframework.web.servlet.tags.RequestContextAwareTag.doStartTag(RequestContextAwareTag.java:80) at org.apache.jsp.WEB_002dINF.jsp.newUser_jsp._jspx_meth_form_005fform_005f0(newUser_jsp.java:197) at org.apache.jsp.WEB_002dINF.jsp.newUser_jsp._jspService(newUser_jsp.java:137) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729)
and more at.....(if it's necessary, I can provide it)
When I try the same code, but exchanging the tag "< form:form >" for the tag "< form >" It works.
When I examined in detail the code from HDIV:
HdivRequestDataValueProcessor.class
public class HdivRequestDataValueProcessor implements RequestDataValueProcessor protected LinkUrlProcessor linkUrlProcessor; protected FormUrlProcessor formUrlProcessor; if (this.innerRequestDataValueProcessor != null) { String processedAction = this.innerRequestDataValueProcessor.processAction(request, action, method); if (processedAction != action) { action = processedAction; } } String result = this.formUrlProcessor.processUrl(request, action, method);//line 122 return result; }I wondered that maybe due to the fact that 'form:form' has a different structure than 'form', HDIV cannot find some parameters such as 'action', 'method'...But I'm not sure.
Also I attached my config files to provide more useful information (Java-based Config):
WebApplicationInit.class
import javax.servlet.Filter; import javax.servlet.ServletContext; import org.hdiv.filter.ValidatorFilter; import org.hdiv.listener.InitListener; import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer; public class WebApplicationInit extends AbstractAnnotationConfigDispatcherServletInitializer { // http://www.robinhowlett.com/blog/2013/02/13/spring-app-migration-from-xml-to-java-based-config/ @Override protected Class<?>[] getRootConfigClasses() { return new Class[] { RootConfig.class, DatabaseConfig.class, SecurityConfig.class, HdivSecurityConfig.class }; // , HdivSecurityConfig.class } @Override protected Class<?>[] getServletConfigClasses() { return new Class[] { MvcConfig.class }; } @Override protected String[] getServletMappings() { return new String[] { "/" }; } //web.xml filter @Override protected Filter[] getServletFilters(){ return new Filter[] { new ValidatorFilter()}; } // web.xml listener @Override protected void registerDispatcherServlet(ServletContext servletContext) { super.registerDispatcherServlet(servletContext); servletContext.addListener(InitListener.class); } }HdivSecurityConfig.class

I changed the way to add the HDIV to my Web Application, adding it in the xml file, instead of doing that in using java-based configuration. Additionally, I added the Qualifier tag (MvcConfig.class), using the example, but it does not work when I use it...(It can not find the bean...). The null error hasn't disappeared...
最满意答案
改变这条线已经解决了这个问题：
@ComponentScan(basePackages = { "com.ec.myWebApp" })在课堂上：MvcConfing，为此：
@ComponentScan(basePackages = { "com.ec.myWebApp.controllers", "com.ec.myWebApp.dao", "com.ec.myWebApp.services" })我的原始行扫描了两次HDIV配置类，首先是在上下文创建期间，第二行是“@ComponentScan”。 这导致了不正确的初始化。 因此，配置包使用了两次，而不是一次。
谢谢。
The problem has been solved changing this line:
@ComponentScan(basePackages = { "com.ec.myWebApp" })in the class: MvcConfing, for this:
@ComponentScan(basePackages = { "com.ec.myWebApp.controllers", "com.ec.myWebApp.dao", "com.ec.myWebApp.services" })My original line scanned twice the HDIV config class, first during the context creation and the second one by the "@ComponentScan". This gave place to an incorrect initialization. So, the config package was used twice, instead of once.
Thank you.
