最近struts2曝的漏洞比较严重,特别写上Spring MVC框架搭建及使用教程
最新的jar包请到Spring官方网站下载:http://www.springsource.org/spring-community-download
1、每个jar包得用处如下:
org.springframework.aop--------------------Spring的面向切面编程,提供AOP(面向切面编程)实现
org.springframework.asm--------------------Spring独立的asm程序,相遇Spring2.5.6的时候需要asmJar 包.3.0开始提供他自己独立的asmJar
org.springframework.aspects----------------Spring提供对AspectJ框架的整合
org.springframework.beans------------------SpringIoC(依赖注入)的基础实现
org.springframework.context.support--------Spring-context的扩展支持,用于MVC方面
org.springframework.context----------------Spring提供在基础IoC功能上的扩展服务,此外还提供许多企业级服务的支持,如邮件服务、任务调度、JNDI定位、EJB集成、远程访问、缓存以及各种视图层框架的封装等
org.springframework.core-------------------Spring3.0的核心工具包
org.springframework.expression-------------Spring表达式语言
org.springframework.jdbc-------------------对JDBC的简单封装
org.springframework.orm--------------------整合第三方的ORM框架,如hibernate,ibatis,jdo,以及spring的JPA实现
org.springframework.test--------------------对Junit等测试框架的简单封装
org.springframework.web--------------------SpringWeb下的工具包
web-context.xml配置

web.xml配置

spring-context为空,后面会加入数据库
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
</beans>
部分注解说明
@Autowired 自动注入[根据类型注入 可以对成员变量、方法以及构造函数进行注释
@Qualifier 标注对象是成员变量、方法入参、构造函数入参。
@Resource 自动注入[根据名称注入],可写参数name=""
@Controller 表示控制器
@Service 表示业务处理层[一般在serviceImpl]
@Repository 表示持久层[一般在daoImpl]
@Component 当你的类不清楚是哪一层的时候使用该注解
@ResponseBody 异步返回数据类型为json
@RequestMapping 路径,请求类型等设置
@InitBinder 数据绑定
