Java 未找到属性异常org.springframework.beans.factory.UnsatisfiedDependencyException:

这似乎是重复的问题，但我无法找到我正在寻找的答案，我的问题略有不同，所以请耐心等待，然后再标记下来或重复-

我有一个保存和删除函数，它使用Book Class对象执行插入和删除操作，而spring将它作为Book Class的一个属性，在使用我丢失的CrudePository或其他东西时，是否有任何具体的方法来实现插入和删除操作，我几乎尝试了这里所有的答案，但都没有帮助，如果你能引导我通过这个问题

这是我目前面临的例外，下面给出了代码-

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'booksController': Unsatisfied dependency expressed through field 'bookService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'bookServiceImpl': Unsatisfied dependency expressed through field 'booksDao'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'booksDao': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property book found for type Books!
