• HTTP Status 500


    跳转页面时出现的错误页面信息:

    HTTP Status 500 - Unable to instantiate Action, com.netbank.action.AdminAction, defined for 'login' in namespace '/admin'Error creating bean with name 'com.netbank.action.AdminAction': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.netbank.biz.UserBiz] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@javax.annotation.Resource(shareable=true, lookup=, name=, description=, authenticationType=CONTAINER, type=class java.lang.Object, mappedName=)}

    这个大概的意思是注入数据源失败,注入失败的原因大多可能是它容器里面就没有生成这些bean类,没有生成bean类,有可能是使用注解时,没有配置它自动扫描,这时可以找一下applicationContext.xml里面有没有写上下面两句,

    <!-- 启动注解 -->
    <context:annotation-config/>
    <!-- 自动扫描,用于@Controller,@Resource等注解 -->

    <context:component-scan base-package="com.xxx"/>

    以上是博主之前遇到的一些错误,在此记录分享一下。
