SSH-----------整合struts\spring\hibernate

出现下面的错误是配置文件加载位置不对，在web.xml改成classpath目录下

基础：4+1 ， beans、core、context、expression ， commons-logging (struts已经导入)

AOP：aop联盟(aopalliance)、spring aop 、aspect规范（aspect.weaver）、spring aspect

db：jdbc、tx

测试：test

web开发：spring web

驱动：mysql

连接池：c3p0

整合hibernate：spring orm

核心包

required包下的介绍

jpa用于注解开发@Entity @Id

create table t_user(

  id int primary key auto_increment,

  username varchar(50),

  password varchar(32),

  age int

);

public class User {

   private Integer id;

   private String username;

   private String password;

   private Integer age;

action中service默认会根据名称注入

默认情况下框架使用的自动装配策略是name，也就是说框架会去 Spring中寻找与action属性名字相同的bean
