简单的Java网页开发SSH框架结构注解方式

1、项目的基本结构

2、applicationContext.xml文件配置

3、config.properties文件配置

#hibernate.dialect=org.hibernate.dialect.OracleDialect

#driverClassName=oracle.jdbc.driver.OracleDriver

#validationQuery=SELECT 1 FROM DUAL

#jdbc_url=jdbc:oracle:thin:@127.0.0.1:1521:orcl

#jdbc_username=sshe

#jdbc_password=sshe

hibernate.dialect=org.hibernate.dialect.MySQLDialect

driverClassName=com.mysql.jdbc.Driver

validationQuery=SELECT 1

jdbc_url=jdbc:mysql://localhost:3306/learningcommunity?useUnicode=true&characterEncoding=UTF-8

jdbc_username=root

jdbc_password=root123

#hibernate.dialect=org.hibernate.dialect.SQLServerDialect

#driverClassName=net.sourceforge.jtds.jdbc.Driver

#validationQuery=SELECT 1

#jdbc_url=jdbc:jtds:sqlserver://127.0.0.1:1433/sy

#jdbc_username=sa

#jdbc_password=123456

hibernate.hbm2ddl.auto=update

hibernate.show_sql=false

hibernate.format_sql=true

hibernate.use_sql_comments=false

sessionInfoName=sessionInfo

4、structs文件配置

<?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>

<!-- 是否启用开发模式 -->

<constant name="struts.devMode" value="false" />

<!-- struts配置文件改动后，是否重新加载 -->

<constant name="struts.configuration.xml.reload" value="true" />

<!-- 设置浏览器是否缓存静态内容 -->

<constant name="struts.serve.static.browserCache" value="false" />

<!-- 请求参数的编码方式 -->

<!-- 每次HTTP请求系统都重新加载资源文件，有助于开发 -->

<constant name="struts.i18n.reload" value="true" />

<!-- 文件上传最大值104857600/(1024*1024)=100M -->

<constant name="struts.tag.altSyntax" value="true" />

<!-- 对于WebLogic,Orion,OC4J此属性应该设置成true -->

<constant name="struts.dispatcher.parametersWorkaround" value="false" />

<package name="basePackage" extends="struts-default">

</package>

</struts>
