Struts2.3.16+Hibernate4.3.1+Spring4.0.2整合.docx

搭建Struts2.3.16，Hibernate4.3.1和Spring4.0.2环境1 下载包hibernate:/orm/downloads/struts2：/download.cgispring4：/release/org/springframework/spring/4.0.2.RELEASE/2 新建空Web Project3 复制struts2常用包到WebRoot/WEB-INF/lib下4 修改web.xml index.jsp struts2 org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter struts2 /* 在WEB-INF下新建jsp文件夹，用来保存jsp文件，也可以直接放在WebRoot下。放在WEB-INF下的好处是只有服务端可以访问。/jsp/Login.jsp： Login /jsp/Welcome.jsp Welcome Welcome! name: $name pwd: $pwd 5 在src目录下新建struts.xml文件struts.xml /WEB-INF/jsp/Login.jsp /WEB-INF/jsp/Welcome.jsp 在src下新建DemoAction.javapackage com.test.struts2;import com.opensymphony.xwork2.ActionSupport;public class DemoAction extends ActionSupport private String name; private String pwd; public String execute() return SUCCESS; public String login() return SUCCESS; public String auth() return SUCCESS; public String getName() return name; public void setName(String name) = name; public String getPwd() return pwd; public void setPwd(String pwd) this.pwd = pwd; 现在的工程结构图：struts就搭好了。访问http:/localhost:8081/demo/Login查看结果。暂时没有做登录验证。只是显示输入的用户名和密码。4 复制hibernate常用包到/WebRoot/WEB-INF/lib下先把lib/required下面的包复制到lib中，然后下载mysql-connector-java-5.1.7-bin.jar 这个包加入。可能会下载到不同的版本，都无所谓。新建Account类：package com.test.model;public class Account private Long id; private String name; private String pwd; public Long getId() return id; public void setId(Long id) this.id = id; public String getName() return name; public void setName(String name) = name; public String getPwd() return pwd; public void setPwd(String pwd) this.pwd = pwd; 新建Account类和数据库表的映射文件Account.hbm.xml： 在本地MySQL或者其他数据库新建数据库demo。新建hibernate配置文件： com.mysql.jdbc.Driver jdbc:mysql:/localhost:3306/demo root root 5 org.hibernate.dialect.MySQLDialect true create thread 根据自己的实际情况填写。现在只要本地可以连接数据库就OK了。新建IDao接口：package com.test.dao.impl;import java.util.List;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.cfg.Configuration;import com.test.dao.IDao;public class IDaoImpl implements IDao private static final SessionFactory sessionFactory; static try sessionFactory = new Configuration() .configure().buildSessionFactory(); catch (Throwable ex) throw new ExceptionInInitializerError(ex); Override public T get(String hql) Session session = sessionFactory.openSession(); try session.beginTransaction(); List list = session.createQuery(hql).list(); if (list != null & list.size() 0) return (T) list.get(0); return null; finally session.getTransaction().commit(); session.close(); 现在Hibernate已经和struts整合完成。实现了用户登录数据库验证。5 搭建Spring环境导入libs/下的*RELEASE.jar文件就可以了。下载commons-dbcp-1.4.jar，commons-pool-1.6.jar包。这两个包跟数据连接池有关。为了实现Service层和dao层的分离，新建Service层。Iservice.java:package com.test.service;public interface IService public T get(String hql); IServiceImpl.javapackage com.test.service.impl;import com.test.dao.IDao;import com.test.service.IService;public class IServiceImpl implements IService private IDao dao; public IDao getDao() return dao; public void setDao(IDao dao) this.dao = dao; Override public T get(String hql) / TODO Auto-generated method stub return dao.get(hql); 为了使用spring，新建applicationContext.xml com/test/model/Account.hbm.xml org.hibernate.dialect.MySQLDialect true true !- - PROPAGATION_REQUIRED 现在Hibernate.cfg.xml已经没用了，删掉这个文件。为了struts和spring结合，加入struts2-spring-plugin-2.3.16.jar包。web.xml index.jsp contextConfigLocation /WEB-INF/classes/applicationContext.xml org.springframework.web.context.ContextLoaderListener struts2 org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter struts2 /* struts.xml /WEB-INF/jsp/Login.jsp /WEB-INF/jsp/Welcome.jsp /WEB-INF/jsp/error.jsp DemoAction.javapackage com.test.struts2;import com.opensymphony.xwork2.ActionSupport;import com.test.model.Account;import com.test.service.IService;public class DemoAction extends ActionSupport private IService service; private String name; private String pwd; public String execute() return SUCCESS; public String login() return SUCCESS; public String auth() String hql = from Account where name= + name + and pwd= + pwd + ; Account account = (Account) service.get(hql); return account = null ? error : SUCCESS; public String getName() return name; public void setName(String name) = name; public String getPwd() return pwd;
