HibernateSpringStruts2ExtJS开发CRUD功能.docx

1、HibernateSpringStruts2ExtJS开发CRUD功能Hibernate+Spring+Struts2+ExtJS开发CRUD功能1、 入门：各种开源框架环境及下载：Hibernate：3.x http:/www.hibernate.org/ 需要hibernate core 和annotations 包。Spring：2.x http:/springframework.org/ Struts2：2.x http:/struts.apache.org/2.x/ ExtJS：2.X JSON：JSON可以到http:/www.json.org/ 查看详细内容，这里使用json-l

2、ib http:/json- 本所需要的包：2、 配置：（1）首先是配置web.xml，配置方法可以在下面的配置文件代码注释中查看，这里主要是Struts2的配置： struts2 org.apache.struts2.dispatcher.FilterDispatcher struts2 /*和Spring的配置： contextConfigLocation /WEB-INF/spring/*.xml org.springframework.web.context.ContextLoaderListenerWeb.xml的全部文件：web-app id=WebApp_ID version=2

3、.4 xmlns= xmlns:xsi=http:/www.w3.org/2001/XMLSchema-instance xsi:schemaLocation= struts2 contextConfigLocation /WEB-INF/spring/*.xml encodingFilter org.springframework.web.filter.CharacterEncodingFilter encoding UTF-8 struts2 org.apache.struts2.dispatcher.FilterDispatcher struts2 /* org.springframew

4、ork.web.context.ContextLoaderListener org.springframework.web.util.IntrospectorCleanupListener 10 index.html index.htm index.jsp default.html default.htm default.jsp （2）Hibernate配置：!DOCTYPE hibernate-configuration PUBLIC -/Hibernate/Hibernate Configuration DTD 3.0/EN oracle.jdbc.driver.OracleDriver

5、MY MY MY jdbc:oracle:thin:localhost:1521:loon org.hibernate.dialect.Oracle9Dialect true （3）Spring基本配置：配置文件应该在WEB-INF/spring/下面 classpath:hibernate.cfg.xml !- 配置多个hibernate.cfg.xml classpath:hibernate_admin1.cfg.xml classpath:hibernate_admin2.cfg.xml - PROPAGATION_REQUIRED,readOnly PROPAGATION_REQUIR

6、ED,-Exception PROPAGATION_REQUIRED,-Exception !- PROPAGATION_REQUIRED PROPAGATION_REQUIRED PROPAGATION_REQUIRED PROPAGATION_REQUIRED PROPAGATION_REQUIRED PROPAGATION_REQUIRED,readOnly PROPAGATION_REQUIRED,readOnly PROPAGATION_REQUIRES_NEW - （4）struts.xml文件的配置： /resource/json_struts2.jsp /resource/js

7、on_struts2.jsp 3、 建立的项目目录：Root：/resource/ext2.0/ 将下载的ext-2.0-beta1.zip文件解压到该目录/WEB-INF/web.xml/WEB-INF/lib/WEB-INF/classes/struts.xml/WEB-INF/spring/applicationContext.xml4、 代码清单： Level.javaimport javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.Id;import javax.persi

8、stence.Table;EntityTable(name = LOON_LEVEL)public class Level implements java.io.Serializable private Long levelid; private String levelname; private String description; public Level() public Level(Long levelid) this.levelid = levelid; public Level(Long levelid, String levelname, String description)

9、 this.levelid = levelid; this.levelname = levelname; this.description = description; Id Column(name = LEVELID, unique = true, nullable = false, precision = 5, scale = 0) public Long getLevelid() return this.levelid; public void setLevelid(Long levelid) this.levelid = levelid; Column(name = LEVELNAME

10、, length = 64) public String getLevelname() return this.levelname; public void setLevelname(String levelname) this.levelname = levelname; Column(name = DESCRIPTION, length = 256) public String getDescription() return this.description; public void setDescription(String description) this.description =

11、 description; ILevelDAO.javaimport java.util.List;public interface ILevelDAO public Level findLevelById(Long id); public List findAllLevels(); public void persistLevel(Level level); public void removeLevel(Level level); public void removeById(Long id);LevelDAO.javaimport java.util.List;import org.hi

12、bernate.Session;import org.springframework.orm.hibernate3.HibernateCallback;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;public class LevelDAO extends HibernateDaoSupport implements ILevelDAO public LevelDAO() super(); public Level findLevelById(Long id) return (Level) getHibernateTemplate().get(Level.class, id); public List findAllLevels() return getHibernateTemplate().loadAll(Level.class);/ .find(from Level o);/
