spring支持4种依赖检查：默认的是none
举个例子
public class Customer { private Person person; private int type; private String action; //getter and setter methods }
public class Person { private String name; private String address; private int age; //getter and setter methods }

注意此处type字段故意没有设置，这样会出现UnsatisfiedDependencyException
org.springframework.beans.factory.UnsatisfiedDependencyException:
Error creating bean with name ‘CustomerBean‘
defined in class path resource [config/Spring-Customer.xml]:
Unsatisfied dependency expressed through bean property ‘type‘:
Set this property value or disable dependency checking for this bean.
