MAVEN_day03 整合SSH框架

时间：2022-06-07 07:59:56

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）

                </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"

        <!-- 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
