Hibernate+Spring+Struts2+ExtJS开发CRUD功能

关键字: extjs
收藏 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 http://extjs.com/ JSON：JSON可以到http://www.json.org/ 查看详细内容，这里使用json-lib http://json-lib.sourceforge.net/ 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： <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> 和Spring的配置： <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring/*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> Web.xml的全部文件： <?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>struts2</display-name>  <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring/*.xml</param-value> </context-param>  <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter>  <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>  <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>  <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener>  <session-config> <session-timeout>10</session-timeout> </session-config> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> </web-app> （2）Hibernate配置： <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!—-数据库驱动类名称 --> <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property> <!—-数据库用户名 --> <property name="hibernate.connection.username">MY</property> <property name="hibernate.default_schema">MY</property> <!—-数据库用户密码 --> <property name="hibernate.connection.password">MY</property> <!—-数据库连接字符串--> <property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:loon</property> <property name="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</property> <!—-控制台是否输出SQL语句 --> <property name="hibernate.show_sql">true</property> <mapping class="privilege.database.Level" /> </session-factory> </hibernate-configuration> （3）Spring基本配置：配置文件应该在WEB-INF/spring/下面 <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans default-autowire="autodetect"> <!—如果用的是XML配置文件，sessionFactory用这个配置 "org.springframework.orm.hibernate3.LocalSessionFactoryBean" --> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="configLocation"> <value>classpath:hibernate.cfg.xml</value> </property>  </bean>  <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <bean id="baseTransactionProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" abstract="true"> <property name="transactionManager" ref="transactionManager" /> <property name="transactionAttributes"> <props> <prop key="find*">PROPAGATION_REQUIRED,readOnly</prop> <prop key="persist*">PROPAGATION_REQUIRED,-Exception</prop> <prop key="remove*">PROPAGATION_REQUIRED,-Exception</prop>  </props> </property> </bean> <bean id="LevelService" parent="baseTransactionProxy"> <property name="target"> <bean class="privilege.service.LevelService"> <property name="dao"> <bean class="privilege.dao.LevelDAO"> <property name="sessionFactory" ref="sessionFactory" /> </bean> </property> </bean> </property> </bean> <bean id="LevelAction" class="privilege.action.LevelAction"> <property name="levelService" ref="LevelService" /> </bean> </beans> （4）struts.xml文件的配置： <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <package name="privilege" extends="struts-default"> <action name="LoadLevel" class="LevelAction" method="findLevelById"> <result>/resource/json_struts2.jsp</result> </action> <action name="LevelAjaxJsonData" class="LevelAction" method="jsonExecute"> <result>/resource/json_struts2.jsp</result> </action> </package> </struts> 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.xml 4、代码清单： Level.java import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.Id; import javax.persistence.Table; @Entity
