spring2.5转到spring3.0找不到bean的解决办法

本文主要是介绍spring2.5转到spring3.0找不到bean的解决办法，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

views.properties

500View.class=org.springframework.web.servlet.view.freemarker.FreeMarkerView
500View.url=common/500.ftl

配置文件  *.xml

<bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver"><property name="cache" value="true"/><property name="prefix" value=""/><property name="suffix" value=".ftl"/><property name="exposeRequestAttributes" value="true" /> <property name="exposeSessionAttributes" value="true" /> <property name="contentType" value="text/html; charset=utf-8"/> <property name="exposeSpringMacroHelpers" value="true"/></bean> <bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer"><property name="templateLoaderPath" value="/WEB-INF/ftl/"/><property name="freemarkerSettings"><props><prop key="template_update_delay">0</prop><prop key="default_encoding">UTF-8</prop> </props></property></bean><!-- 属性文件方式解析资源文件 --><bean id="viewResolverProperties" class="org.springframework.web.servlet.view.ResourceBundleViewResolver"> <property name="basename"> <value>views</value> </property> </bean> <!-- Mapping exception to the handler view --> <bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"> <!-- to /commons/error.jsp --> <property name="defaultErrorView" value="500View"/> <property name="exceptionMappings"> <props> </props> </property> </bean>

 

controller跑出异常之后报错

java.lang.IllegalStateException: No bean class specified on bean definition

 

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '500View': Instantiation of bean failed; nested exception is java.lang.IllegalStateException: No bean class specified on bean definition

解决办法：

500View.class=org.springframework.web.servlet.view.freemarker.FreeMarkerView
500View.url=common/500.ftl
改为

500View.(class)=org.springframework.web.servlet.view.freemarker.FreeMarkerView
500View.url=common/500.ftl

多了一个括号，  有些兴趣可用看一下spring加载bean时的源码， spring3.0和spring2.5的一个区别，，，

这篇关于spring2.5转到spring3.0找不到bean的解决办法的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
