[解决办法]
自己把报错信息看清楚，
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'costService' defined in class path resource [applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [financesj.center.service.CostServiceImpl]: Is it an abstract class?; nested exception is java.lang.InstantiationException
Could not instantiate bean class [financesj.center.service.CostServiceImpl]: Is it an abstract class?;
确认下这个类是不是抽象类，

'costService' 有问题啊你看下你的Service啊 确认下这个类是不是抽象类，
[解决办法]
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'costService' defined in class path resource [applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [financesj.center.service.CostServiceImpl]: Is it an abstract class?; nested exception is java.lang.InstantiationException
检查一下你的financesj.center.service.CostServiceImpl这个对象。看是否是抽象类。
