SSH框架系列之框架整合教程

àì夳堔傛蜴生んèń 2021-09-10 18:50 423阅读 0赞

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

![Center][]

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

![Center 1][]

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

![Center 2][]

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：

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE struts PUBLIC

Hibernate的配置文件代码：

    <!DOCTYPE hibernate-configuration PUBLIC

    </session-factory>
    
    </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

    public class Student {

    	/*
    	 * 班级
    	 */
    	private String stuName;
    	
    	/*

    	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() {

    	public String getStuSex() {

    	}
    
    	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

    	}
    
    	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

实现数据获取
