在maven环境下 基于Struts2 spring hibernate用户登录及查询整合案例

在maven环境下 基于Struts2 spring hibernate用户登录及查询整合案例

maven环境的配置：

去网上下载apache-maven-2.2.1-bin.zip文件，然后解压至c盘根目录下

高级环境变量，配置环境如下：maven_home=C:\apache-maven-2.2.1 path=%maven_home%\bin

然后进入该项目下输入maven的编译命令：mvn eclipse:myeclipse

以下是相关代码

登陆页index.jsp，只贴了主要的代码，

<fieldset>
<legend>用户登录</legend>
<div style="color:red"><s:property value="msg"/></div>
<form action="login.action" method="post">
<s:textfield name="username" label="用户名" /><br/>
<s:password name="password" label="密 码" /><br/>
<input type="submit" value="登  录"/>
<input type="reset" value="取  消" />
</form>
</fieldset>

登陆成功页welcome.jsp

<div align="center">恭喜<s:property value="username"/> 登录成功！！</div>
<hr/>
<div align="center"><a href="userList.action">显示用户列表</a></div>
<br/>
<table width="70%" align="center" cellpadding="0" cellspacing="0" border="1">
<tr>
<th>用户编号</th>
<th>用户姓名</th>
<th>用户性别</th>
<th>用户年龄</th>
<th>出生日期</th>
<th>联系电话</th>
<th>联系地址</th>
</tr>
<s:iterator id="userDO" value="userList">

将struts.xml,spring-ds.xml,spring-biz.xml放置src目录下，但是使用maven创建的工程之后，有一个src/maini/resources目录，将这些文件放置该目录下即可

具体的java代码，可以新建一个源文件,名称为src/main/java，该文件放入java实现代码，比如控制层，业务逻辑层，数据访问层，实体类等
