原创 Centos、Ubuntu玩转记录
1.Centos升级yum update2.Ubuntu升级sudo apt-get update3.Ubuntu以root登陆-->vi /usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf新增一行greeter-show-manual-login=true3.Ubuntu在修改完root权限自动登录后,发现开机出现以下

原创 ClassCastException: $Proxy0 cannot be cast to ...
Spring AOP代理时 ClassCastException: $Proxy0 cannot be cast to (类型转换错误)spring的文档中这么写的:Spring AOP部分使用JDK动态代理或者CGLIB来为目标对象创建代理,如果被代理的目标对象实现了至少一个接口,则会使用JDK动态代理。所有该目标类型实现的接口都将被代理。若该目标对象没有实现任何接口,则创建一个CGL

原创 java传引用笔记
class P{ public String name = "";}public class T{ public void fn(P p) { p = new P(); //p是形参。传进来的实参(即一个P实例的首地址)会被放到形参p中,但是下面一new就会把new出的空间首地址放到形参p中 //这样p.name就是对新new的实例的name属性赋值 //而如果
