解决方案
解决方案二：
这个是springsimpleformcontroller的配置文件，我一运行它就报错，错误如下：严重:Exceptionsendingcontextinitializedeventtolistenerinstanceofclassorg.springframework.web.context.ContextLoaderListenerorg.springframework.beans.factory.BeanCreationException:Errorcreatingbeanwithname'testAction'definedinServletContextresource[/WEB-INF/applicationContext.xml]:Initializationofbeanfailed;nestedexceptionisorg.springframework.beans.InvalidPropertyException:Invalidproperty'commandClass'ofbeanclass[com.demo.spring.actions.TestAction]:Noproperty'commandClass'foundCausedby:org.springframework.beans.InvalidPropertyException:Invalidproperty'commandClass'ofbeanclass[com.demo.spring.actions.TestAction]:Noproperty'commandClass'foundatorg.springframework.beans.BeanWrapperImpl.convertForProperty(BeanWrapperImpl.java:376)atorg.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues(AbstractAutowireCapableBeanFactory.java:1111)atorg.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:861)atorg.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:421)atorg.springframework.beans.factory.support.AbstractBeanFactory$1.getObject(AbstractBeanFactory.java:251)atorg.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:156)atorg.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:248)atorg.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:160)atorg.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:733)atorg.springframework.web.servlet.handler.AbstractUrlHandlerMapping.registerHandler(AbstractUrlHandlerMapping.java:256)atorg.springframework.web.servlet.handler.SimpleUrlHandlerMapping.registerHandlers(SimpleUrlHandlerMapping.java:125)atorg.springframework.web.servlet.handler.SimpleUrlHandlerMapping.initApplicationContext(SimpleUrlHandlerMapping.java:103)atorg.springframework.context.support.ApplicationObjectSupport.setApplicationContext(ApplicationObjectSupport.java:73)atorg.springframework.context.support.ApplicationContextAwareProcessor.postProcessBeforeInitialization(ApplicationContextAwareProcessor.java:72)atorg.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyBeanPostProcessorsBeforeInitialization(AbstractAutowireCapableBeanFactory.java:301)atorg.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1167)atorg.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:425)atorg.springframework.beans.factory.support.AbstractBeanFactory$1.getObject(AbstractBeanFactory.java:251)atorg.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:156)atorg.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:248)atorg.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:160)atorg.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons(DefaultListableBeanFactory.java:287)atorg.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:352)atorg.springframework.web.context.ContextLoader.createWebApplicationContext(ContextLoader.java:244)atorg.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:187)atorg.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:49)atorg.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4205)atorg.apache.catalina.core.StandardContext.start(StandardContext.java:4704)atorg.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:799)atorg.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:779)atorg.apache.catalina.core.StandardHost.addChild(StandardHost.java:601)atorg.apache.catalina.startup.HostConfig.deployDirectory(HostConfig.java:1079)atorg.apache.catalina.startup.HostConfig.deployDirectories(HostConfig.java:1002)atorg.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:506)atorg.apache.catalina.startup.HostConfig.start(HostConfig.java:1315)atorg.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:324)atorg.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:142)atorg.apache.catalina.core.ContainerBase.start(ContainerBase.java:1061)atorg.apache.catalina.core.StandardHost.start(StandardHost.java:840)atorg.apache.catalina.core.ContainerBase.start(ContainerBase.java:1053)atorg.apache.catalina.core.StandardEngine.start(StandardEngine.java:463)atorg.apache.catalina.core.StandardService.start(StandardService.java:525)atorg.apache.catalina.core.Sta

解决方案三：
testAction里面有没有commandClass这个变量应该没有吧
解决方案四：
没有啊这个simpleformcontroller不是不用创建commandClass属性么？我看介绍说不用，说它是继承的abstractformcontroller，已经有该属性，只要在配置文件里写入就行了，难道还需要在控制类里去创建一个？
解决方案五：
com.demo.spring.actions.TestAction类里面请设置commandClass的getter/setter
解决方案六：
你的com.demo.spring.actions.TestAction继承了什么类应该没有commandClass这个变量
解决方案七：
不中啊到底怎么回事呢郁闷
解决方案八：
packagecom.demo.spring.actions;importjava.net.BindException;importjavax.servlet.http.HttpServletRequest;importjavax.servlet.http.HttpServletResponse;importorg.springframework.web.servlet.ModelAndView;importorg.springframework.web.servlet.mvc.SimpleFormController;importcom.demo.spring.formbeans.TestForm;publicclassTestActionextendsSimpleFormController{protectedModelAndViewonSubmit(HttpServletRequestrequest,HttpServletResponseresponse,Objectcommand,BindExceptionerrors)throwsException{TestFormtf=(TestForm)command;Stringusername=tf.getUsername();Stringpassword=tf.getPassword();if(username.equals("admin")&&password.equals("admin")){returnnewModelAndView(getSuccessView());}if(!username.equals("admin")||!password.equals("admin")){returnnewModelAndView(getFormView());}returnnull;}}
解决方案九：
我刚开始学spring这个是老师让做的实验。是继承那个simpleformcontroller
解决方案十：
你什么学校的啊?
解决方案十一：
垃圾二本的咋啦？
解决方案十二：
到底是怎么回事啊？
解决方案十三：
配置文件中声明了testAction类有一个属性叫commandClass但是Spring在初始化testAction类的时候没有找到它有commandClass这个属性所以报错了~
解决方案十四：
testAction里没有set和getcommandClass的方法？1
解决方案十五：
好像不是这个问题，这个属性应该不用我管的，直接就能用的，因为它是继承的父类的属性啊。
解决方案：
Invalidproperty'commandClass'ofbeanclass[com.demo.spring.actions.TestAction]:Noproperty'commandClass'found这是你的异常堆栈里的信息所以我判断是这个问题
