4、SSH集成笔记

1.各框架版本如下:

• spring-framework-3.2.4.RELEASE-dist.zip
• struts-2.3.8-all.zip
• hibernate-release-4.2.8.Final.zip

2.目录结构如下:

3.用到的jar包如下:

4.web.xml文件内容如下:

   <?xml version="1.0" encoding="UTF-8"?>

        <param-value>/WEB-INF/applicationContext-*.xml,classpath*:applicationContext-*.xml,classpath*:applicationContext*.xml</param-value>
    </context-param>
</web-app>

 

5.applicationContext.xml文件内容如下(事务还有注入bean都是xml方式,基于注解方式的还没有弄):

    <constant name="struts.objectFactory" value="spring" />
    <package name="login" namespace="/login" extends="struts-default">

        <!-- 此处用loginAction而不用com.zmp.action.LoginAction是因为spring已为其创建了实例 -->
        <action name="check" class="loginAction" method="execute">
            <result name="success">/success.html</result>
            <result name="failed">/failed.html</result>
