SSH框架系列之框架整合教程
【摘要】
我以我做的一个例子来说明框架的搭建过程 ^V^！

我以我做的一个例子来说明框架的搭建过程 ^V^！
项目结构如图：
action：存放Action类，也就是控制类
dao：DAO数据库操作
po：POJO类，也就是持久化类
service：存放Service类
dao类在Service类里调用，然后Service类再到action类里调用
搭建过程
我们先要准备jar价包，这个可以去官网下载
下面是我准备的开发jar价包
然后我为了提高安全性，我将所有的JSP页面放在了WEB-INF下面
然后配置SSH的配置文件
Spring的配置文件代码：
-
<?xml version="1.0" encoding="UTF-8"?>

前面那些配置文件有包含其它的，这个要根据自己的项目需要去改的^V^
下面以学生信息管理的实现过程进行说明，只说明这个例子哈！
创建POJO实体类：

-
String sql = "from Student";
-
List<Student> students = (List<Student>) ht.find(sql);

-
-
public String getPassword() {
-
return password;
-
}
-
-
public void setPassword(String password) {
-
this.password = password;
-
}
-
-
/**
-
* 获取学生的基本信息
-

-
* @throws Exception
-
*/
-
//@Override
-
public String getAllInfo() throws Exception {
-
studentsInfo = studentService.getAllStudentInfo();
-
return SUCCESS;
-
}
-
}
然后就可以在JSP页面引入
<%@ taglib uri="/struts-tags" prefix="s" %>
然后获取数据了
-
<table class="table table-hover">
-
<tr>
-
<th width="120">学号</th>
-
<th width="120">姓名</th>
-
<th width="120">性别</th>
-
<th width="120">班级</th>
-
<th width="120">系部</th>
-
<th width="100">出生年月</th>
-
<th width="100">操作</th>
-
</tr>
-
<s:iterator value="studentsInfo" id="ssif" >
-
<tr>
-
<td><s:property value="#ssif.stuID" /></td>
-
<td><s:property value="#ssif.stuName" /></td>
-
<td><s:property value="#ssif.stuSex" /></td>
-
<td><s:property value="#ssif.className" /></td>
-
<td><s:property value="#ssif.dept" /></td>
-
<td><s:property value="#ssif.stuBirth" /></td>
-
<td>
-
<a class="button border-blue button-little" href="getStuInfoByIdAction?stuID=<s:property value='#ssif.stuID'/>">详情</a>
-
<a class="button border-yellow button-little" href="getLearnScoresAction?stuID=<s:property value='#ssif.stuID' />" >学习</a>
-
<a class="button border-green button-little" href="getMatchScoresAction?stuID=<s:property value='#ssif.stuID' />">比赛</a>
-
</td>
-
</tr>
-
</s:iterator>
-
</table>
实现数据获取
这是我结合Bootstrap和SSH做的，结合例子来说明实现过程，希望可以帮到学习的人，有疑惑请留言哈！^V^
