struts2.3.4.1+spring3.1.1+hibernate3.6.10框架整合搭建，解决UnsatisfiedDependencyException

环境： struts2.3.4.1+spring3.1.1+hibernate3.6.10+MySQL 5.5

前期配置没什么大问题，除了几个jar包引入的时候出了点状况，现在把所需的jar包截图，大多数在下载的SSH框架中都有，没有的单独下载吧

整合完毕，配置SSH，主要配置文件如下：

Web.xml：

	
	
		index.jsp
	
	
	
		struts2
		org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
	
	
		struts2
		*.action
	
	
	
		contextConfigLocation
		classpath:applicationContext.xml
	
	
		org.springframework.web.context.ContextLoaderListener
	
	
	
		org.springframework.web.util.Log4jConfigListener
	
	
		log4jConfigLocation
		classpath:log.properties
	

Struts：

	
		
			/pages/userInfoList.jsp
		
	
        

Spring：

	
	
		
		
		
		
		

		
		
		
		
		

		
		

		
		

		
		

		

	


	
		
			classpath:database.properties
		
	
	
		
		
		
			
				
					classpath:/com/mytest/dto/*.hbm.xml
				
			
		
		
			
				20

				
					org.hibernate.dialect.MySQL5Dialect
				
				false
			
		
	
	
	
	
		
	

	
		
			
			
			
		
	

	

	
		
	

	
	
		
	

	
		
	

	
		 
	
		

Hibernate：

然后启动，报异常如下：

百度、Google了一堆，查了一堆API，去官网看了框架版本change logs，demo……之后终于找到原因了

原来是Spring配置的beans的bean装配属性default-autowire="autodetect"，配置成了自动，所以产生了这个异常。于是删除它，改为在每个Dao层手动注入.

重启，运行，一切正常

问题暂时解决了，不过还是有疑问，因为这样在每个DAO层的bean中都要手动通过property属性，来配置注入，不知道default-autowire="autodetect" 这个属性要怎么配置才能实现自动注入？
