文檔簡(jiǎn)介

1、jdk6+myeclipse8.5+tomcat6+oracle+spring2.0+hibernate3+struts2 好了，開(kāi)始我們的第一個(gè)ssh2之旅吧。 首先先分析一下我們的第一個(gè)ssh2項(xiàng)目的需求，簡(jiǎn)單的說(shuō)就是有一張表單，讓你填寫(xiě)用戶(hù)名和密碼，提交后存入數(shù)據(jù)庫(kù)。就這么簡(jiǎn)單，呵呵。 第一步：。我們首先新建一張mysql數(shù)據(jù)表。Sql如下： Create table t_employee（Id integer not null primary key,Name varchar(20),Age varchar(20),Sex varchar(20),Tel varchar(20),Add

2、ress varchar(20)）數(shù)據(jù)創(chuàng)建好后結(jié)構(gòu)如下：第二步 打開(kāi)myeclipse，新建一個(gè)web項(xiàng)目，命名為ssh2-2, java ee規(guī)范我們選擇5，如圖 第三步 務(wù)必小心的一步 導(dǎo)入ssh2的各個(gè)jar，步驟如下： 選中當(dāng)前的項(xiàng)目后，點(diǎn)擊菜單爛的myeclipse-project capablities-add hibernate項(xiàng)，跳出如圖 務(wù)必按照?qǐng)D示選擇，尤其是copy checkde一項(xiàng)，然后點(diǎn)擊next，默認(rèn)next，去掉specify database復(fù)選框，next，去掉create session復(fù)選框，finish。 再次選中選中當(dāng)前的項(xiàng)目后，點(diǎn)擊菜單爛的myec

3、lipse-project capablities-add spring項(xiàng)，跳出如圖 依然務(wù)必按照如是選擇，jar文件選擇如下5個(gè)： 點(diǎn)擊next， 之后按下選擇，務(wù)必， next后finsh即可。 然后導(dǎo)入struts2的jar 如下5個(gè)放到lib下 然后放入我們的數(shù)據(jù)庫(kù)驅(qū)動(dòng)jar mysql-connector-java-5.0.8-bin.jar 沒(méi)得話(huà)附件中有 至此，包都導(dǎo)入完畢 第四步 配置web.xml 代碼如下 注意注釋?zhuān)?Xml代碼 1. <?xml version="1.0" encoding="UTF-8"?

14、p>第五步： 從視圖層入手；在webroot目錄下新建一個(gè)add.jsp文件 如下代碼； Jsp代碼 <% page language="java" import="java.util.*" pageEncoding="UTF-8"%><% taglib uri=" prefix="c"%><% taglib prefix="s" uri="/struts-tags" %> <%String path = reques

15、t.getContextPath();String basePath = request.getScheme()+":/"+request.getServerName()+":"+request.getServerPort()+path+"/"%><!DOCTYPE HTML PUBLIC "-/W3C/DTD HTML 4.01 Transitional/EN"><html> <head> <base href="<%=basePath%>&q

22、ype="submit" value="提交"></td> </tr> </table> </form> </body></html>接下去順?biāo)浦郏匀婚_(kāi)發(fā)action，及控制層 新建包c(diǎn)om.ucap.emp.action新建一個(gè)EmployeeAction.java 代碼初步如下： Java代碼 package com.ucap.emp.action;import java.util.List;import org.apache.struts2.ServletAction

23、Context;import com.opensymphony.xwork2.ActionSupport;import com.ucap.emp.pojo.Employee;import com.ucap.emp.service.EmployeeService;public class EmployeeAction extends ActionSupport private Employee employee; private List<Employee> list; private EmployeeService employeeService; public List<E

24、mployee> getList() return list;public void setList(List<Employee> list) this.list = list;public EmployeeService getEmployeeService() return employeeService;public void setEmployeeService(EmployeeService employeeService) this.employeeService = employeeService; public Employee getEmployee() r

25、eturn employee;public void setEmployee(Employee employee) this.employee = employee; /查詢(xún) public String list() list = this.employeeService.findAll(employee); / ServletActionContext.getRequest().setAttribute("list", list);return "list" /增加 public String add()return "add" /

26、增加保存 public String addSave() this.employeeService.save(this.employee); employee=new Employee();return list(); /更改之前 public String updateBefore() employee=this.employeeService.findById(employee.getId();return "update" /更改 public String update() this.employeeService.update(employee); employe

27、e=new Employee();return list(); /刪除 public String delete() this.employeeService.delete(employee);return list();于是，自然我們要新建一個(gè)pojo 新建包c(diǎn)om.ucap.emp.pojo 新建Employee.java Java代碼 package com.ucap.emp.pojo;public class Employee private Integer id; private String name; private String age ; private String sex

28、 ; private String tel; private String address; public Employee() public Employee(Integer id, String name, String age, String sex, String tel,String address) super();this.id = id; = name;this.age = age;this.sex = sex;this.tel = tel;this.address = address;public Integer getId() return id;publ

29、ic void setId(Integer id) this.id = id;public String getName() return name;public void setName(String name) = name;public String getAge() return age;public void setAge(String age) this.age = age;public String getSex() return sex;public void setSex(String sex) this.sex = sex;public String g

30、etTel() return tel;public void setTel(String tel) this.tel = tel;public String getAddress() return address;public void setAddress(String address) this.address = address; 好了，現(xiàn)在我們先把控制層的action放在這里，開(kāi)發(fā)業(yè)務(wù)層和持久層（DAO） 新建包c(diǎn)om.ucap.emp.dao 建類(lèi)EmployeeDAO.java 代碼如下： Java代碼 package com.ucap.emp.dao;import java.ut

31、il.List;import com.ucap.emp.pojo.Employee;public interface EmployeeDao public void saveEmployee(Employee employee); public void removeEmployee(Employee employee); public void updateEmployee(Employee employee); public Employee findEmployeeById(Integer id); public List<Employee> findAllEmployee(

32、Employee employee);這是一個(gè)接口 在開(kāi)發(fā)dao的實(shí)現(xiàn)類(lèi) 新建包c(diǎn)om.ucap.emp.dao.impl 建類(lèi)EmployeeDAOImpl.java 代碼： Java代碼package com.ucap.emp.dao.impl;import java.util.List;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;import com.ucap.emp.dao.EmployeeDao;import com.ucap.emp.pojo.Employee;public class

33、EmployeeDaoImpl extends HibernateDaoSupport implements EmployeeDao public List<Employee> findAllEmployee(Employee employee) String hql="from Employee "String where =" where 1= 1 "if(employee.getName()!=null&&!"".equals(employee.getName()hql+=where+" a

34、nd name like '%"+employee.getName()+"%' order by id desc"return this.getHibernateTemplate().find(hql); public void saveEmployee(Employee employee) this.getHibernateTemplate().save(employee); public void updateEmployee(Employee employee) this.getHibernateTemplate().update(emplo

35、yee);public void removeEmployee(Employee employee) this.getHibernateTemplate().delete(employee); public Employee findEmployeeById(Integer id) Employee employ=(Employee) this.getHibernateTemplate().get(Employee.class, id);return employ;好了，數(shù)據(jù)持久層（dao）開(kāi)發(fā)好了，按順序，現(xiàn)在應(yīng)該開(kāi)發(fā)業(yè)務(wù)層了， 新建包c(diǎn)om.ucap.emp.service 建類(lèi)Emplo

36、yeeService.java 代碼： Java代碼package com.ucap.emp.service;import java.util.List;import com.ucap.emp.pojo.Employee;public interface EmployeeService public void save(Employee employ);public void update(Employee employ);public void delete(Employee employ);public List<Employee> findAll(Employee emplo

37、yee);public Employee findById(Integer id);這是一個(gè)接口類(lèi) 然后寫(xiě)實(shí)現(xiàn)類(lèi) 新建包 com.ucap.emp.service.impl 建類(lèi) EmployeeServiceImpl.java Java代碼package com.ucap.emp.service.impl;import java.util.List;import com.ucap.emp.dao.EmployeeDao;import com.ucap.emp.pojo.Employee;import com.ucap.emp.service.EmployeeService;public cl

38、ass EmployeeServiceImpl implements EmployeeService private EmployeeDao employeeDao; public EmployeeDao getEmployeeDao() return employeeDao;public void setEmployeeDao(EmployeeDao employeeDao) this.employeeDao = employeeDao; /服務(wù)層方法public void delete(Employee employ) this.employeeDao.removeEmployee(emp

39、loy);public List<Employee> findAll(Employee employ) return this.employeeDao.findAllEmployee(employ); public Employee findById(Integer id) return this.employeeDao.findEmployeeById(id);public void save(Employee employ) this.employeeDao.saveEmployee(employ);public void update(Employee employ) thi

40、s.employeeDao.updateEmployee(employ);業(yè)務(wù)和持久層都開(kāi)發(fā)好了，現(xiàn)在我們回到控制層action 修改action的代碼如下： Java代碼 （查看前面完整的action層代碼）這里就不做出來(lái)了。修改struts.xml 如下 Xml代碼<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC "-/Apache Software Foundation/DTD Struts Configuration 2.0/EN"

41、"/dtds/struts-2.0.dtd"> <struts> <package name="employ" namespace="/emp" extends="struts-default"> <action name="*employee" class="employeeAction" method="1"> <result name="add&q

42、uot; >/add.jsp</result> <result name="update" >/update.jsp</result> <result name="list" >/list.jsp</result> </action> </package></struts>至此，我們已經(jīng)開(kāi)發(fā)好了一個(gè)典型的mvc項(xiàng)目，現(xiàn)在的任務(wù)是將strust2和hibernate都放入spring容器管理， 現(xiàn)在我們的項(xiàng)目結(jié)構(gòu)如下然后修改 applicationCont

43、ext.xml 代碼如下 注意注釋 Xml代碼 <?xml version="1.0" encoding="UTF-8"?><beansxmlns="/schema/beans"xmlns:xsi="/2001/XMLSchema-instance"xsi:schemaLocation="/schema/beans http:/www.spr
