public class Role {    private Log id;    private String roleName;    private String note;        public Role(String roleName, String note) {        this.roleName = roleName;        this.note = note;    }    @Override    public String toString() {        return "Role{" +                "id=" + id +                ", roleName='" + roleName + '\'' +                ", note='" + note + '\'' +                '}';    }}

　　测试代码：

public static void main(String[] args) {        ApplicationContext A=new ClassPathXmlApplicationContext("spring/my-spring.xml");        Object role1 = A.getBean("role1");        //System.out.println(((Role)role1).toString());        System.out.println((Role)role1);    }

 

 结果：
