基于Annotation的SSH整合例子 Struts2 Spring3 Hibernate3

 

 

之前写了一个简单的SSH整合例子
http://blog.sina.com.cn/s/blog_57769b7b0100tr7j.html
这次在上面例子的基础上把Annotation的实现也做一下。

Struts2和hibernate的注解都是非常好理解的。
如果你看不懂Spring的注解的话，请先看一下这里http://blog.sina.com.cn/s/blog_57769b7b0100tt3u.html

 

需要jar

1.Hibernate
-hibernate-jpa-2.0-api-1.0.1.Final.jar
hibernate-annotations-3.4.0.GA.zip(http://sourceforge.net/projects/hibernate/files/hibernate-annotations/)
-ejb3-persistence.jar

2.Spring
javaee.jar (http://www.jarfinder.com/index.php/jars/versionInfo/62754)

3.Struts
struts2-convention-plugin-2.2.3.jar

 

注意:

1.有些web服务器默认的j2ee版本比较低..javaee.jar尽量也放在web服务器上比较稳妥..

 例如tomcat的话..就把javaee-api-5.0.5.jar放在apache-tomcat-5.5.26\common\lib下

2.数据库连接的驱动jar不要忘记..也要放在apache-tomcat-5.5.26\common\lib下
