Struts就是使MVC模式应用于web程序设计。hibernate可以自动生成SQL语句，自动执行，使得Java程序员可以随心所欲的使用对象编程思维来操纵数据库。
1.先导lib
2.新建"hibernate.cfg.xml"文件
<?xml version='1.0' encoding='utf-8'?> <!-- ~ Hibernate, Relational Persistence for Idiomatic Java ~ License: GNU Lesser General Public License (LGPL), version 2.1 or later. ~ See the lgpl.txt file in the root directory or <http://www.gnu.org/licenses/lgpl-2.1.html>. --> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- Database connection settings --> <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <property name="connection.url">jdbc:mysql://localhost:3306/xgnfyd?</property> <property name="connection.username">root</property> <property name="connection.password">xxx</property> <property name="hibernate.temp.use_jdbc_metadata_defaults">false</property> <!-- JDBC connection pool (use the built-in) --> <!-- <property name="connection.pool_size">1</property> --> <!-- SQL dialect --> <property name="dialect">org.hibernate.dialect.MySQLDialect</property> <!-- Disable the second-level cache --> <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property> <!-- Echo all executed SQL to stdout --> <property name="show_sql">true</property> <property name="format_sql">true</property> <!-- Drop and re-create the database schema on startup --> <!-- <property name="hbm2ddl.auto">create</property> --> <!-- Names the annotated entity class --> <mapping class="cn.whb.model.UserInfo"/> </session-factory> </hibernate-configuration>数据库的表要与model类对应，如UserInfo类对应数据库中user_info表，在UserInfo类应加入标注如下图所示
3.新建struct.xml文件
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <!-- <constant name="struts.enable.DynamicMethodInvocation" value="false" /> <constant name="struts.devMode" value="true" /> <package name="default" namespace="/" extends="struts-default"> <default-action-ref name="index" /> <global-results> <result name="error">/WEB-INF/jsp/error.jsp</result> </global-results> <global-exception-mappings> <exception-mapping exception="java.lang.Exception" result="error"/> </global-exception-mappings> <action name="index"> <result type="redirectAction"> <param name="actionName">HelloWorld</param> <param name="namespace">/example</param> </result> </action> </package> <include file="example.xml"/> --> <constant name="struts.devMode" value="true" /> <!-- 表示启用struts2的DMI --> <constant name="struts.enable.DynamicMethodInvocation" value="true"></constant> <constant name="struts.i18n.encoding" value="utf-8"></constant> <!-- 表示允许OGNL访问类的静态方法 --> <constant name="struts.ognl.allowStaticMethodAccess" value="true"></constant> <package name="default" namespace="/" extends="struts-default"> <default-action-ref name="error"></default-action-ref> <action name="error" class="cn.whb.action.ErrorAction" method="doError"> </action> </package> <!--方法--> <package name="user" namespace="/user" extends="default"> <action name="login" class="cn.whb.action.DoLogin" method="doUserAction"> </action> </package> <!-- Add packages here --> </struts>4.在web.xml添加过滤
<filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
其它
hibernate自动生成表
//读取配置文件 Configuration cfg = new Configuration().configure(); //创建SchemaExport对象 SchemaExport export = new SchemaExport(cfg); //创建数据库表 export.create(true,true);
