首先工作是导入jar包

需要的jar包：测试需要的jar包 junit

spring系列的jar包 spring-webmvc（spring-aop spring-beans spring-context spring-core spring-expression spring-web） spring-jdbc spring-orm aspectjweaver aspectjrt aopalliance aop切面

hibernate jar包 hibernate-core hibernate-ehcache

连接数据库的jar包 commons-logging commons-dbcp(commons-pool) mysql-connector-java

日志的jar包 slf4j-api slf4j-log4j12 log4j-core

文件上传 commons-fileupload

转json fastjson

缓存 ehcache

配置文件

添加web目录，配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         version="3.1">

    <!-- Spring的OpenSessionInView实现 -->
    <filter>
        <filter-name>openSessionInViewFilter</filter-name>
        <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter
        </filter-class>
        <!-- singleSession默认为true,若设为false则等于没用OpenSessionInView 。所以默认可以不写-->
        <init-param>
            <param-name>singleSession</param-name>
            <param-value>true</param-value>

        <!--

        -->
        <init-param>
            <param-name>sessionFactoryBean</param-name>
            <param-value>sessionFactory</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>openSessionInViewFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!--filter 过滤器 用来解决中文乱码问题-->
    <filter>
        <filter-name>characterEncoding</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>utf-8</param-value>

    <filter-mapping>

    <servlet>
        <servlet-name>default1</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc-servlet.xml</param-value>

    <servlet-mapping>
        <servlet-name>default1</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--配置spring-->
    <!-- 配置去哪裡加載spring的配置文件 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <!-- 配置spring的監聽器，加載資源初始化文件 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
</web-app>

添加数据库连接配置文件

db.properties

dbcp.driverClassName=com.mysql.jdbc.Driver
dbcp.url=jdbc:mysql://localhost:3306/onetomore
dbcp.username=root
dbcp.password=123456
dbcp.maxActive=100
dbcp.initialSize=5

在applicationContext.xml中配置读取db.properties的配置

使用${}读取文件,这里我前面加个前缀，不然读取不了，一定跟前面的name=“”不一样就行

<!--从上下文环境中读取db.properties配置文件-->
    <context:property-placeholder location="classpath*:db.properties"></context:property-placeholder>

    <bean id="dataSource"  class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="${dbcp.driverClassName}"></property>
        <property name="url" value="${dbcp.url}"></property>
        <property name="username" value="${dbcp.username}"></property>
        <property name="password" value="${dbcp.password}"></property>
        <property name="maxActive" value="${dbcp.maxActive}"></property>
        <property name="initialSize" value="${dbcp.initialSize}"></property>
    </bean>

添加hibernate，生成实体类

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>

        <property name="connection.url">jdbc:mysql://localhost:3306/java1807</property>
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.username">root</property>
        <property name="connection.password">123456</property>

        <!--数据库表示什么引擎，它就是什么引擎-->
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>


        <!--显示sql-->
        <property name="hibernate.show_sql">true</property>
        <!--美化sql，格式化sql语句-->
        <property name="hibernate.format_sql">true</property>

        <!--使用二级缓存-->
        <property name="hibernate.cache.use_second_level_cache">true</property>
        <!--配置二级缓存服务商-->
        <property name="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</property>
        <!--使用查询缓存-->
        <property name="cache.use_query_cache">true</property>
        
        <mapping resource="Area.hbm.xml"/>
        <mapping resource="City.hbm.xml"/>
        <mapping resource="Province.hbm.xml"/>
        
      <!--  <mapping class="com.qy.domain.Province"></mapping>
        <mapping class="com.qy.domain.City"></mapping>
        <mapping class="com.qy.domain.Area"></mapping>-->
        <!-- <property name="connection.username"/> -->
        <!-- <property name="connection.password"/> -->

        <!--配置读写-->

        <class-cache class="com.qy.domain.Province" usage="read-write"></class-cache>
        <!-- DB schema will be updated if needed -->
        <!-- <property name="hbm2ddl.auto">update</property> -->
    </session-factory>
</hibernate-configuration>

将hibernate和spring整合

删除hibernate.cgf.xml文件，把hibernate的文件配置在application.xml中

  <!-- 配置Hibernate的SessionFactory -->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <!--指定当前会话工厂使用的数据源-->
        <property name="dataSource" ref="dataSource"></property>
        <!--指定实体类的位置-->
        <property name="packagesToScan"  value="com.qy.domain"/>
       <!-- <property name="annotatedClasses">
            <list>
                <value>com.qy.domain.Province</value>
            </list>
        </property>-->
        <property name="hibernateProperties">
            <value>
                hibernate.dialect=org.hibernate.dialect.MySQLDialect
                hibernate.show_sql=true
                hibernate.format_sql=true
                <!--  hibernate.hbm2ddl.auto=create -->
            </value>
        </property>
    </bean>

总结

项目运行时，先读取web.xml文件，根据web.xml读取到applicationContext.xml和springmvc-servlet.xml文件，在springmvc-servlet文件主要配置view层的东西，视图解析器，返回json字符串乱码问题，文件上传，定义注解扫描的包，这里只扫描controller层。applicationContext.xml中也要开始注解扫面，扫描的是除了controller层的其他层。读取db.properties配置文件，配置Hibernate的sessionFacory，替代hibernate.cfg.xml文件，最后是配置事务的属性，切入点。这样框架就可以运行起来。可以在seivice层或者test中测试。
