Struts2.3.16.1+Hibernate4.3.4+Spring4.0.2 框架整合
最新版Struts2+Hibernate+Spring整合
目前为止三大框架最新版本是:
struts2.3.16.1
hibernate4.3.4
spring4.0.2
其中struts2和hibernate的下载方式比较简单,但是spring下载有点麻烦,可以直接复制下面链接下载最新版spring
http://repo.springsource.org/libs-release-local/org/springframework/spring/4.0.2.RELEASE/spring-framework-4.0.2.RELEASE-dist.zip
一. 所需的jar包(其中aopaliance-1.0.jar,是spring所依赖的jar,直接复制粘贴到谷歌百度就有的下载)
框架 | 版本 | 所需jar包 |
Struts2 | 2.3.16.1 |
Hibernate | 4.3.4 |
spring | 4.0.2 |
其它 | 无 |
二. 创建一张表
- CREATE TABLE `user` (
- `id` int(11) NOT NULL AUTO_INCREMENT,
- `user_name` varchar(20) DEFAULT NULL,
- `password` varchar(20) DEFAULT NULL,
- `address` varchar(100) DEFAULT NULL,
- `phone_number` varchar(20) DEFAULT NULL,
- `create_time` datetime DEFAULT NULL,
- `update_time` datetime DEFAULT NULL,
- PRIMARY KEY (`id`)
- ) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULTCHARSET=utf8;
- ---并插入一条数据
- INSERT INTO `user` VALUES ("1‘, ‘test‘,‘test‘, ‘test‘, ‘test‘, ‘2014-03-29 00:48:14‘, ‘2014-03-29 00:48:17‘);
三. 先看下myeclipse的目录结构

FreeMark的配置
为了在FreeMarker模板中使用标签库,可按如下步骤进行
1.将struts-tags.tld文件复制到WEB-INF目录下
即将系统所需的标签库定义文件(*.tld文件)复制到web应用中。对于基于struts2框架的JAVA_Web应用,则需要将Struts2-core.jar包解压,取出其中的struts-tags.tld文件,并复制到web应用的WEB-INF目录下。同时所需的最少Jar包如下图
2.在web.xml文件中启动JspSupportServlet
在web.xml文件中作如下配置,如下:
- <servlet>
- <servlet-name>JspSupportServlet</servlet-name>
- <servlet-class>org.apache.struts2.views.JspSupportServlet</servlet-class>
- <!--配置JspSupportServlet自启动-->
- <load-on-startup>1</load-on-startup>
- </servlet>
此配置本人没配FreeMark一样可以,具体用处有待研究。
3. 在FreeMarker模板文件中使用“assign指令”导入标签库
导入标签库的代码如下:
- <#--定义web-inf/strust-tags.tld文件对应的标签库前缀为s-->
- <#assigns=JspTaglibs["/WEB-INF/struts-tags.tld"]/>
说明:在上面导入的标签库定义文件中,指定了标签库前缀为s,而该前缀对应的标签库定义文件主放置在/WEB-INF/struts-tags.tld路径下、
4.完毕
经过上述步骤后,即可在应用的FreeMarker模板中使用Struts2标签。在FreeMarker模板中增加了标签库定义后,就可以在FreeMarker模板中使用Struts2标签了。在FreeMarker使用标签与在jsp中使用标签略有差别.
补充说明
我们不能直接通过浏览器直接请求该页面,否则看到的不是我们想要的结果,而是该模板页面的源代码(因为WEB容器默认不会处理 FreeMarker模板页面)。
正如前面使用FreeMarker模板作为视图组件时看到的,FreeMarker作为视图组件是由Servlet负责加载该模板,并使用数据模型填充该模板,并且填充后的标准HTML响应输出给浏览者。
在Strtus2框架的支持下,Struts2框架充当了之前的Servlet角色,只要浏览者的请求经过了Struts2处理后,Struts2框架就会自动加载FreeMarker模板,并使用数据模型填充该模板,并且将最后的HTML页面输出给浏览者.。
为了让所有的用户请求都经过Struts2框架处理,我们将所有的FreeMarker模板文件放在web-inf/ftl路径下.
因为浏览者无法直接访问web-inf/ftl路径下的资源,所以我们在struts.xml配置文中增加了如下配置片段:
- <action name="*">
- <result type="freemarker">/WEB-INF/ftl/{1}.ftl</result>
- </action>
也就是把原来的Action中的result属性中type值改成“freemarker”
五. JAVA类
1.BaseDAO.java(网上找的一个)
