SSH框架系列之框架整合教程

2022-05-07 15:20:08 浏览数 (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:

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:

代码语言:javascript复制
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

代码语言:javascript复制

DAO实现

代码语言:javascript复制
import java.util.List;

import com.sgdata.po.Student;

public interface StudentDao {

	/**
	 * 获取所有学生信息
	 * @return
	 */
	public List<Student> getAllStudentInfo();
	
}
代码语言:javascript复制
public class StudentDaoImpl extends HibernateDaoSupport implements StudentDao {
	
	@Resource HibernateTemplate ht;
	
	/**
	 * 获取所有信息
	 */
	public List<Student> getAllStudentInfo() {
		String sql = "from Student";
		List<Student> students = (List<Student>) ht.find(sql);
		return students;
	}
}

Service实现:

代码语言:javascript复制
import java.util.List;

import com.sgdata.po.Student;

public interface StudentService {

	/**
	 * 获取所有学生信息
	 * @return
	 */
	public List<Student> getAllStudentInfo();
	}
代码语言:javascript复制
import java.util.List;

import javax.annotation.Resource;

import org.springframework.transaction.annotation.Transactional;

import com.sgdata.dao.StudentDao;
import com.sgdata.po.Student;
import com.sgdata.service.StudentService;

@Transactional(readOnly=false)
public class StudentServiceBean implements StudentService {

	@Resource private StudentDao studentDao;
	public List<Student> getAllStudentInfo() {
		return studentDao.getAllStudentInfo();
	}
}

Action实现:

代码语言:javascript复制
/**
 * 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 stuSex;
	
	//出生年月
	private String stuBirth;
	
	//电话
	private String stuTel;
	
	//邮箱
	private String stuEmial;
	
	//系部
	private String dept;
	
	//身份证
	private String stuIDCard;
	
	//班级
	private String className;
	
	//密码
	private String password;
	
	/**
	 * 学生对象来储存学生信息
	 */
	private Student student;
	
	/**
	 * 学生信息的列表
	 */
	private List<Student> studentsInfo;
	
	/**
	 * 学生学习成绩的信息列表
	 */
	private List learnScores;
	
	/**
	 * 学生比赛成绩的信息列表
	 */
	private List matchScores;
	
	public StudentInfoManagerAction(){
		//student = new Student();
		
	}
	
	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() {
		return stuName;
	}

	public void setStuName(String stuName) {
		this.stuName = stuName;
	}

	public String getStuSex() {
		return stuSex;
	}

	public void setStuSex(String stuSex) {
		this.stuSex = stuSex;
	}

	public String getStuBirth() {
		return stuBirth;
	}

	public void setStuBirth(String stuBirth) {
		this.stuBirth = stuBirth;
	}

	public String getStuTel() {
		return stuTel;
	}

	public void setStuTel(String stuTel) {
		this.stuTel = stuTel;
	}

	public String getStuEmial() {
		return stuEmial;
	}

	public void setStuEmial(String stuEmial) {
		this.stuEmial = stuEmial;
	}

	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;
	}

	/**
	 * 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

代码语言:javascript复制
 <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^
