springmvc整合mybatis 实现商品信息提交功能时报错Field error in object 'itemsCustom' on field 'createtime'

附上完整错误信息：

org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBindingResult: 1 errorsField error in object 'itemsCustom' on field 'createtime': rejected value [2015-02-03 13:22:53]; codes [typeMismatch.itemsCustom.createtime,typeMismatch.createtime,typeMismatch.java.util.Date,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [itemsCustom.createtime,createtime]; arguments []; default message [createtime]]; default message [Failed to convert property value of type [java.lang.String] to required type [java.util.Date] for property 'createtime'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [java.util.Date] for value '2015-02-03 13:22:53'; nested exception is java.lang.IllegalArgumentException]at org.springframework.web.method.annotation.ModelAttributeMethodProcessor.resolveArgument(ModelAttributeMethodProcessor.java:118)at org.springframework.web.method.support.HandlerMethodArgumentResolverComposite.resolveArgument(HandlerMethodArgumentResolverComposite.java:121)at org.springframework.web.method.support.InvocableHandlerMethod.getMethodArgumentValues(InvocableHandlerMethod.java:161)at org.springframework.web.method.support.InvocableHandlerMethod.invokeForRequest(InvocableHandlerMethod.java:128)at org.springframework.web.servlet.mvc.method.annotation.ServletInvocableHandlerMethod.invokeAndHandle(ServletInvocableHandlerMethod.java:114)at org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter.invokeHandlerMethod(RequestMappingHandlerAdapter.java:827)at org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter.handleInternal(RequestMappingHandlerAdapter.java:738)at org.springframework.web.servlet.mvc.method.AbstractHandlerMethodAdapter.handle(AbstractHandlerMethodAdapter.java:85)at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:963)at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:897)at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:970)at org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:872)at javax.servlet.http.HttpServlet.service(HttpServlet.java:650)at org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:846)at javax.servlet.http.HttpServlet.service(HttpServlet.java:731)at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:303)at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:208)at org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:241)at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:208)at org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:197)at org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:107)at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:241)at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:208)at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:218)at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:110)at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:506)at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:169)at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103)at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:962)at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:116)at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:445)at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1115)at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:637)at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:318)at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source)at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61)at java.lang.Thread.run(Unknown Source)

错误原因是我在用mybatis逆向工程自动生成po类时定义的createtime为java.util.Date类型（错误信息中的itemsCustom为createtime所在商品信息类的扩展类），而修改商品信息页面的jsp文件中规定createtime的相关信息如下

即二者的日期格式不一致导致了该错误的产生

解决方法：

1.在相关的controller.java文件中增加数据绑定代码：

@InitBinderpublic void initBinder(WebDataBinder binder) {        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");        dateFormat.setLenient(false);        binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true)); }

应导入的相关类有：

2.也可以自定义日期类型绑定，即加入一个日期类型转换器

public class CustomDateConverter implements Converter<String,Date>{public Date convert(String source) {SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");try {return simpleDateFormat.parse(source);} catch (ParseException e) {e.printStackTrace();}return null;}}

并在springmvc的配置文件中配置：

<mvc:annotation-driven conversion-service="conversionService"></mvc:annotation-driven><!-- 自定义参数绑定 --><bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean"><!-- 转换器 --><property name="converters"><list><!-- 日期类型转换 --><bean class="ssm.controller.converter.CustomDateConverter"/></list></property></bean>
