Invalid property 'name' of bean class

在Struts2 +  Hibernate4 +  Spring3.2 整合的时候出现的：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: 
        Error creating bean with name 'dataSource' defined in class path resource [applicationContext.xml]: 
        Error setting property values; 
        nested exception is org.springframework.beans.NotWritablePropertyException: 
       Invalid property 'name' of bean class [org.apache.commons.dbcp.BasicDataSource]: 
       Bean property 'name' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

我的applicationContext.xml配置文件是这样的：

    
    
    
    
        
        
        
        
        
        
        
        
        
        
    
    
    
        
        
        
        
        
            
                org.hibernate.dialect.MySQLDialect
                update
                true
            
            
        
        
        
            
                com/ssh/domain/Employee.hbm.xml
            
        
    
    
    

原来是：

 name" value="root"/>

写错了，改成：

 username" value="root"/>

问题解决。
