搭建SSM项目, pom文件的 Spring的依赖疑问, 可以这样设置 Spring的依赖么?
**1. 问题描述:** 在尝试这搭建 SSM 项目的过程中, 我是看着 Spring的结构图去添加 pom.xml 中的依赖的, 比如 core部分只需要添加 spring-context 依赖即可. 然后 context 会自动去依赖 core, beans, aop, expression. 所以, 在搭建SSM项目时, Spring 依赖我只添加六个了 context, orm, webmvc, context-support, aspects, test 如果不需要日志和测试的话, 后面两个去掉 也是可以的. 请问各位大佬, 这样子搭建, 符不符合规范??? ** 2. 相关代码:** ``` <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0"

hibernate4 无法连接postgreSQL数据库

Linux(内核剖析):19---中断总体概述
一、为什么要引入中断? 任何操作系统内核的核心任务,都包含有对连接到计算机上的硬件设备进行有效管理,如硬盘、蓝光碟机、键盘、鼠标、3D 处理器,以及无线电等。而想要管理这些设备,首先要能和它们互通音信才行。众所周知,处理器的速度跟外围硬件设备的速度往往不在一个数量级上,因此,如果内核采取让处理器向硬件发出一个请求,然后专门等待回应的办法,显然差强人意。既然硬件的响应这么慢,那么内核就应该在此期间...

智力题(程序员面试经典)
