Warming: StandardWrapper.Throwable

2、 Cause of the problem:

There are two spring IOC configuration files in the project: beanDefines.xml and springMVC.xml .among beanDefines.xml There is no spring component scanning configuration available stay springMVC.xml The configuration of spring component scanning is as follows: < context:component-scan base-package= “com” />. thus beanDefines.xml It works springMVC.xml The configuration of spring component scanning is carried out. beanDefines.xml The bean defined in was not scanned, causing the exception.

 

3、 Solutions:

The two spring IOC configuration files are configured with different ranges of spring component scanning

1.springMVC.xml

	<context:component-scan base-package="com" use-default-filters="false">
	  		<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
	</context:component-scan>
           
        <task:annotation-driven/>

2. Biendefen

     <context:component-scan base-package="com" use-default-filters="false">
	  		<context:include-filter type="annotation" expression="org.springframework.stereotype.Service" />
     </context:component-scan>
