搭建SSH三大框架WEB项目过程(Struts2.3+Hibernate4.3+Spring4.1)
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：

Struts2的配置文件代码：

</hibernate-configuration>
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：
import java.util.Date;
import java.util.HashSet;
import java.util.Set;
/**
*
* 学生信息的实体类
* @author Nicky
*
*/
public class Student {
/*
* 学号
*/
private String stuID;
/*
* 班级
*/
private String stuName;
/*
* 性别
*/
private String stuSex;
/*
* 出生年日
*/
private Date stuBirth;
/*
* 电话
*/
private String stuTel;
/*
* 邮箱
*/
private String stuEmail;
/*
* 专业
*/
private String dept;
/*
* 身份证
*/
private String stuIDCard;
/*
* 班级
*/
private String className;
/*
* 登录密码
*/
private String password;
/*
* 是否是管理员的标志 1表示是，0表示不是
*/
private String isManager;
public String getStuID() {
return stuID;
}
public void setStuID(String stuID) {
this.stuID = stuID;
}
public String getStuName() {
return stuName;
}
public void setStuName(String stuName) {
this.stuName = stuName;
}
public String getStuSex() {
return stuSex;
}
public void setStuSex(String stuSex) {
this.stuSex = stuSex;
}
public Date getStuBirth() {
return stuBirth;
}
public void setStuBirth(Date stuBirth) {
this.stuBirth = stuBirth;
}
public String getStuTel() {
return stuTel;
}
public void setStuTel(String stuTel) {
this.stuTel = stuTel;
}
public String getStuEmail() {
return stuEmail;
}
public void setStuEmail(String stuEmail) {
this.stuEmail = stuEmail;
}
public String getDept() {
return dept;
}
public void setDept(String dept) {
this.dept = dept;
}
public String getStuIDCard() {
return stuIDCard;
}
public void setStuIDCard(String stuIDCard) {
this.stuIDCard = stuIDCard;
}
public String getClassName() {
return className;
}
public void setClassName(String className) {
this.className = className;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getIsManager() {
return isManager;
}
public void setIsManager(String isManager) {
this.isManager = isManager;
}
}
配置Student.hbm.xml文件
<?xml version="1.0" encoding="UTF-8"?>

DAO实现
import java.util.List;
import com.sgdata.po.Student;
public interface StudentDao {

public List<Student> getAllStudentInfo();
}
public class StudentDaoImpl extends HibernateDaoSupport implements StudentDao {

/**

*/
public List<Student> getAllStudentInfo() {
String sql = "from Student";
List<Student> students = (List<Student>) ht.find(sql);
return students;
}
}
Service实现：
import java.util.List;

public interface StudentService {

@Transactional(readOnly=false)
public class StudentServiceBean implements StudentService {
@Resource private StudentDao studentDao;
public List<Student> getAllStudentInfo() {
return studentDao.getAllStudentInfo();
}
}
Action实现：
/**
* 实现学生信息管理的Action类
*
*/
public class StudentInfoManagerAction extends ActionSupport {
/**
*
*/
private static final long serialVersionUID = 1L;
@Resource private StudentService studentService;
//页数
int pagenum = 0;
//学号
private String stuID;
//姓名
private String stuName;
//性别

private String stuTel;
//邮箱
private String stuEmial;
//系部
private String dept;

public StudentInfoManagerAction(){

}
public Student getStudent() {
return student;
}
public void setStudent(Student student) {
this.student = student;
}
public void setStudentsInfo(List<Student> studentsInfo){
this.studentsInfo = studentsInfo;
}
public List<Student> getStudentsInfo() {
return studentsInfo;
}
public List getLearnScores() {
return learnScores;
}
public void setLearnScores(List learnScores) {
this.learnScores = learnScores;
}
public List getMatchScores() {
return matchScores;
}
public void setMatchScores(List matchScores) {
this.matchScores = matchScores;
}
public int getPagenum() {
return pagenum;
}
public void setPagenum(int pagenum) {
this.pagenum = pagenum;
}
public String getStuID() {
return stuID;
}
public void setStuID(String stuID) {
this.stuID = stuID;

public String getStuName() {

}
public void setStuName(String stuName) {

public String getStuSex() {

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