SHH框架搭建

创建WEB项目并引入相应的jar包

在/ASSH/WebRoot/WEB-INF/lib目录下面放置需要的jar包

Struts2的jar包

下载好

struts2

包后，打开

struts-2.3.24\apps

找到

struts2-blank.war

使用压缩软件打开，在

struts2-blank.rar\WEB-INF\lib

目录下所有的包拷贝到项目的

lib

目录下

打开

struts-2.3.24\struts-2.3.24-lib

目录下找到下面两个

jar包

struts2-convention-plugin-2.3.24.jar

:支持struts2的注解的jar包

struts2-spring-plugin-2.3.24.jar

:支持spring整合的jar包，一般情况下可有可无，在引入spring的时候也会有这样一个类似的jar包，两个jar包任选一个就可以了

Hibernate的jar包

hibernate所有的jar包

日志记录，整合log4j的jar包

slf4j-api-1.6.1.jar

slf4j-log4j12-1.7.5.jar

Spring的jar包

ioc：

spring-beans-4.0.5.RELEASE.jar

spring-context-4.0.5.RELEASE.jar

spring-core-4.0.5.RELEASE.jar

spring-expression-4.0.5.RELEASE.jar

AOP:

spring-aop-4.0.5.RELEASE.jar

spring-aspects-4.0.5.RELEASE.jar

com.springsource.org.aopalliance-1.0.0.jar

com.springsource.org.aspectj.weaver-1.6.8.RELEASE.jar

事务管理的包：

spring-tx-3.2.0.RELEASE.jar

spring-jdbc-3.2.0.RELEASEjar

整合hibernate的包：

spring-orm-4.0.5.RELEASE.jar

整合WEB项目：

spring-web-4.0.5.RELEASE.jar

整合Junit单元测试：

spring-test-4.0.5.RELEASE.jar

c3p0连接池：

com.springsource.com.mchange.v2.c3p0-0.9.1.2.jar

SHH框架整合实例

上面引入所需要的各种jar包之后，还需要创建各个框架所必须的配置文档。

目的：创建数据库

ssh

和

product

表用来存放数据。在页面中输入商品名称和价格，然后点击提交按钮，将数据提交至数据库中并保存。

hibernate负责将接收到的数据保存至数据库中，struts2负责业务的具体逻辑操作的执行，spring负责解耦和注入。

项目结构

action：负责执行业务逻辑

service：负责业务逻辑

dao：负责数据库层逻辑操作

网页中输入：http://127.0.0.1:8080/AsshDemo/addProduct.jsp

输入数据并提交：



控制台输出
