  • 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）

    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            <!-- 设置编译版本为1.8 -->

                <groupId>org.apache.maven.plugins</groupId>

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

    　　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
