Answer 1

Unable to instantiate Action, com.sinba.crm.et.action.MarketActivityAction, defined for 'etActivity' in namespace '/'Error creating bean with name 'com.sinba.crm.et.action.MarketActivityAction': Injection of autowired dependencies failed; 
struts.xml文件配置错误 
nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.sinba.crm.et.service.IMarketActivityService com.sinba.crm.et.action.MarketActivityAction.etActivityService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.sinba.crm.et.service.IMarketActivityService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations:
这个类在spring里没有注入吧

Answer 2

No matching bean of type [com.sinba.crm.et.service.IMarketActivityService] found for dependency: 
自动装载的bean没找到，好好检查下吧。

Answer 3

Unable to instantiate Action, com.sinba.crm.et.action.MarketActivityAction, defined for 'etActivity' in namespace '/'Error creating bean with name 'com.sinba.crm.et.action.MarketActivityAction': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.sinba.crm.et.service.IMarketActivityService com.sinba.crm.et.action.MarketActivityAction.etActivityService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.sinba.crm.et.service.IMarketActivityService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}1.可能是Struts的配置文件struts.xml里的action的包名写的不对吧
2.可能是Spring的配置写的不正确，导致bean没有注入。  
3.web.xml的spring和struts配置要保证正确哦

Answer 4

com.sinba.crm.et.action.MarketActivityAction, defined for 'etActivity' in namespace '/'Error creating bean with name 'com.sinba.crm.et.action.MarketActivityAction': Injection of autowired dependencies failed;
检查一下你配置文件里面的etActivity的配置，可能路径或者名称写错了，注意大小写
