SSH框架搭建流程

一.SSH框架简介

SSH搭建流程

struts2配置

struts-2.3.30-all\struts-2.3.30\apps

struts2-blank

WEB-INF/lib

struts2-blank\WEB-INF\src\java

二.Spring配置

spring-framework-4.2.2.RELEASE-dist\spring-framework-4.2.2.RELEASE\libs

-resource,jar

-javadoc.jar

<!-- spring的监听器配置开始 -->
<!-- 配置上下文参数，保存 applicationContext.xml 文件的路径，该文件一般直接写在 src 目录下 -->
<context-param>
<!-- 参数名称（固定不变） -->
<param-name>contextConfigLocation</param-name>
<!-- classpath（即src目录），":"等价于"/"，多个配置文件之间用","隔开 -->
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- 监听器配置 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

三.Hibernate配置

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
<!-- name="实体类的包名.类名" table="表名" -->
<class name="ssh.entity.BookCard" table="BOOKCARD">
<!-- id元素表内主键字段对应实体类字段 -->
<id name="cid" type="int">
<column name="CID" />
<generator class="assigned" /><!-- 标识符生成器，主键生成规则 -->
</id>
<!-- 将实体类字段和表内字段一一对应 -->
<property name="name" type="java.lang.String">
<column name="NAME" />
</property>
<property name="sex" type="java.lang.String">
<column name="SEX" />
</property>
<property name="cardDate" type="java.util.Date">
<column name="CARDDATE" />
</property>
<property name="deposit" type="java.math.BigDecimal">
<column name="DEPOSIT" />
</property>
</class>
</hibernate-mapping>
