三大框架配置[注解模式版].doc

三大框架配置注解模式版1.新建web项目2.添加hibernate框架3.添加Spring框架4.添加Struts2框架Struts2 JAR包导入选中并复制所有JAR包粘贴到项目lib文件夹下重复操作将Struts2中Spring支持JAR包导入lib文件夹下复制粘贴到项目lib文件夹下5.将dbcp JAR包导入礼包文件夹下完成后所有JAR包添加成功6.hibernate.cfg.xml文件中的datasource，hbernateproperties，mappingresource/mappingclass均可在applicationContext.xml中添加。可将hibernate.cfg.xml文件删除后在applicationContext.xml中配置。在applicationContext.xml中修改头文件，改为如下：在applicationContext.xml中配置datasource，hbernateproperties，mappingresource/mappingclass将生成的LocalSessionFactoryBean修改为AnnotationSessionFactoryBean添加功能配置7.包的创建8.数据库反射创建dto，dao。生成的类中Student中属性的long类型修改为int，StudentDAO中的的log属性删除生成的StudentDAO和StudentDAOImpl，可根自身习惯将方法实体写入StudentDAOImpl，而接口类写入StudentDAO。在此只需更改类名，互换包的位置即可9.Service类，Service接口类，Action类StudentServices类：package com.hrs.services;import java.util.List;import org.hibernate.SessionFactory;import org.springframework.beans.factory.annotation.Autowired;import com.hrs.model.Student;public interface Studentservice void save(Student transientInstance);void delete(Student persistentInstance);Student findById(java.lang.Long id);List findAll();Student merge(Student detachedInstance);StudentServiceImpl类package com.hrs.services.impl;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Propagation;import org.springframework.transaction.annotation.Transactional;import com.hrs.dao.Studentdao;import com.hrs.model.Student;import com.hrs.services.Studentservice;Service(studentservice)Transactional(propagation=Propagation.REQUIRED)public class StudentserviceImpl implements Studentservice private Studentdao studentdao;public void save(Student transientInstance) System.out.println(我是数据服务层);studentdao.save(transientInstance);public void delete(Student persistentInstance) studentdao.delete(persistentInstance);public Student findById(Long id) return studentdao.findById(id);public List findAll() return studentdao.findAll();public Student merge(Student detachedInstance) return studentdao.merge(detachedInstance);Autowiredpublic void setStudentdao(Studentdao studentdao) this.studentdao = studentdao;StudentAction类package com.hrs.actions;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import com.hrs.model.Student;import com.hrs.services.Studentservice;import com.opensymphony.xwork2.ActionSupport;Controller(studentAction)public class StudentAction extends ActionSupport private Student stu;private Studentservice service;Autowiredpublic void setService(Studentservice service) this.service = service;public Student getStu() return stu;public void setStu(Student stu) this.stu = stu;public String save() System.out.println(stu);System.out.println(我是业务逻辑层);service.save(stu); return this.SUCCESS;ApplicationContext.xml文件org.hibernate.dialect.Oracle9Dialectupdatetrue com.hrs.model.Student Struts2.xml文件/index.jsp 10.web.xml配置 index.jsp encodingorg.springframework.web.filter.CharacterEncodingFilterencodingUTF-8encoding/*contextConfigLocationclasspath:applicationContext.xmlorg.springframework.web.context.ContextLoaderListenerOpenSessionInViewFilterorg.springfram
