MAVEN_day03 整合SSH框架
一、整合SSH工程环境准备
1.创建MAVEN工程>>添加>>"web.xml"文件解决工程红色叹号。
new Maven Project>>在src>main>webapp>创建WEB-INF文件夹，并导入web.xml文件
2.解决编译版本问题，在pom.xml中，添加版本编译代码，以下是需要整合SSH代码。（代码已经解决jar冲突问题）

二、开始编码（整合SSH所需的配置文件，切记在web.xml文件中配置struts核心过滤器、spring拦截器）
1.strus.xml、applicationContext.xml、hibernate.cfg.xml 需要放在src/main/resources文件夹下，相当于普通工程的src文件夹下。以下是个文件模板
strut.xml
<?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> <!-- 配置常量 --> <!-- 字符集 --> <constant name="struts.i18n.encoding" value="UTF-8"></constant> <!-- 开发模式 --> <constant name="struts.devMode" value="true"></constant> <!-- 主题 --> <constant name="struts.ui.theme" value="simple"></constant> <!-- 扩展名 --> <constant name="struts.action.extension" value="action"></constant> <!-- 通用package --> <package name="customer" namespace="/" extends="struts-default"> <action name="" class="全路径" method="方法名"> <result name="success"></result> </action> </package> </struts>
applicationContext.xml
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 数据库连接池 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="com.mysql.jdbc.Driver" /> <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/maven" /> <property name="user" value="root" /> <property name="password" value="root" /> </bean> <!-- 配置sessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"> <!-- 依赖dataSource --> <property name="dataSource" ref="dataSource"/> <!-- 创建工厂需要加载hibernate映射文件 --> <property name="configLocations" value="classpath:hibernate.cfg.xml"></property> </bean> <bean id="customerDao" class="全路径"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> </beans>
hibernate.cfg.xml
<?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <!-- 会话工厂 --> <session-factory> <!-- 数据库方言，根据数据库选择 --> <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property> <!--为了方便调试是否在运行hibernate时在日志中输出sql语句 --> <property name="hibernate.show_sql">true</property> <!-- 是否对日志中输出的sql语句进行格式化 --> <property name="hibernate.format_sql">true</property> <property name="hibernate.hbm2ddl.auto">none</property> <!-- 加载映射文件 --> <mapping resource="cn/itcast/crm/bean/Customer.hbm.xml"/> </session-factory> </hibernate-configuration>
2.实体的配置问价放在与对应的java代码同一个文件夹上。如下图所示
3.测试dao代码（我习惯从底层编码） 测试代码是要存放在src/test/java文件夹下的位置
4.测试结果
5.创建service层
5.1注入dao
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 数据库连接池 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="com.mysql.jdbc.Driver" /> <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/maven" /> <property name="user" value="root" /> <property name="password" value="root" /> </bean> <!-- 配置sessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"> <!-- 依赖dataSource --> <property name="dataSource" ref="dataSource"/> <!-- 创建工厂需要加载hibernate映射文件 --> <property name="configLocations" value="classpath:hibernate.cfg.xml"></property> </bean> <bean id="customerDao" class="cn.itcast.crm.dao.impl.CustomerDaoImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="customerService" class="cn.itcast.crm.service.impl.CustomerServiceImpl"> <property name="customerDao" ref="customerDao"></property> </bean> <bean id="customerAction" class="cn.itcast.crm.action.CustomerAction" scope="prototype"> <property name="customerService" ref="customerService"></property> </bean> </beans>
6.创建Action
6.1通过Action 在jsp从值栈中获取
