SSM + Freemarker 开发框架快速搭建

1.项目骨架建立

一、使用开发工具IDEA,构建Maven项目,然后调整Maven项目结构,使其成为一个标准的web项目：

• 此处不选择Maven骨架，直接Next:

  

• 输入项目的相关信息，直接Finish

  

• 项目构建完成后，选择pom.xml 打包方式为 war

  <packaging>war</packaging>
  

  

• 选择1，建立项目的webapp目录，选择2，在指定目录的WEB-INF下建立web.xml文件：

  

项目最终构建完成结构层次图:

2.整合SSM + FreeMarker:

一、数据库资源文件配置：

# 数据库配置文件 db.properties
db.username=root
db.password=root
db.url=jdbc:mysql:///meeting?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai

二、Spring配置：

<?xml version="1.0" encoding="UTF-8"?>
<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:tx="http://www.springframework.org/schema/tx"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop https://www.springframework.org/schema/aop/spring-aop.xsd">

    <!--Spring配置文件，配置注解扫描，使用过滤器不扫描Controller注解-->
    <context:component-scan base-package="org.taoguoguo.meeting" use-default-filters="true">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!--加载外部资源-->
    <context:property-placeholder location="classpath:db.properties" />

    <!--数据源配置-->
    <bean class="com.alibaba.druid.pool.DruidDataSource" id="dataSource">
        <property name="username" value="${db.username}" />
        <property name="password" value="${db.password}" />
        <property name="url" value="${db.url}" />
    </bean>

    <!--mybatis配置-->
    <bean class="org.mybatis.spring.SqlSessionFactoryBean" id="sqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="typeAliasesPackage" value="org.taoguoguo.meeting.model" />
        <!--mapper资源加载多路径配置-->
        <property name="mapperLocations">
            <array>
                <value>classpath:mapper/*Mapper.xml</value>
                <value>classpath:org/taoguoguo/meeting/mapper/*Mapper.xml</value>
            </array>
        </property>
    </bean>

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" id="mapperScannerConfigurer">
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactoryBean" />
        <property name="basePackage" value="org.taoguoguo.meeting.mapper" />
    </bean>

    <!--事务配置-->
    <!-- 配置事务管理器 -->
    <bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager" id="transactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!--定义属性，声明事务规则 -->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="add*" propagation="REQUIRED"/>
            <tx:method name="insert*" propagation="REQUIRED"/>
            <tx:method name="update*" propagation="REQUIRED"/>
            <tx:method name="delete*" propagation="REQUIRED"/>
        </tx:attributes>
    </tx:advice>

    <!--定义切面-->
    <aop:config>
        <aop:pointcut id="pc1" expression="execution(* org.taoguoguo.meeting.service.*.*(..))"/>
        <!-- 将事务增强与切入点组合（织入事务切面） -->
        <aop:advisor advice-ref="txAdvice" pointcut-ref="pc1" />
    </aop:config>

    <!--注解方式配置事务
    <tx:annotation-driven transaction-manager="transactionManager" />
    -->
</beans>

三、SpringMVC配置：

<?xml version="1.0" encoding="UTF-8"?>
<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:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!--Springmvc配置文件 只扫描Controller注解-->
    <context:component-scan base-package="org.taoguoguo.meeting" use-default-filters="true">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!--注解驱动 HandlereMapping & HandlerAdapter-->
    <mvc:annotation-driven />

    <!--静态资源放行-->
    <mvc:resources mapping="/**" location="/" />

    <!--加载外部资源文件-->
    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>classpath:freemarker-var.properties</value>
            </list>
        </property>
    </bean>

    <!--配置模板基本属性-->
    <bean class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer" id="freeMarkerConfigurer">
        <!--模板文件位置-->
        <property name="templateLoaderPath" value="/WEB-INF/ftl/"/>
        <!--默认编码格式-->
        <property name="defaultEncoding" value="UTF-8" />
        <!--全局变量设置-->
        <property name="freemarkerVariables">
            <map>
                <entry key="root" value="${root}" />
            </map>
        </property>
        <!--基本格式配置：时间格式、数字格式-->
        <property name="freemarkerSettings">
            <props>
                <!--模版的缓存时间，单位是s，超过缓存时间则从磁盘加载最新的模版-->
                <prop key="template_update_delay">10</prop>
                <!--设置默认地区，主要影响数字、日期输出格式，request中没有指定地区时模板查找的值-->
                <prop key="locale">zh_CN</prop>
                <!--设置日期时间的输出格式。-->
                <prop key="datetime_format">yyyy-MM-dd HH:mm:ss </prop>
                <!--设置日期的输出格式-->
                <prop key="date_format">yyyy-MM-dd</prop>
                <!--设置时间的输出格式-->
                <prop key="time_format">HH:mm:ss</prop>
                <!--设置数字的输出格式-->
                <prop key="number_format">#.####</prop>
            </props>
        </property>
    </bean>

    <!--freemarker视图解析器配置-->
    <bean class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
        <!--视图解析器类-->
        <property name="viewClass" value="org.springframework.web.servlet.view.freemarker.FreeMarkerView" />
        <!--后缀配置-->
        <property name="suffix" value=".ftl"/>
        <!--设置各种属性覆盖-->
        <!--允许重写Request属性-->
        <property name="allowRequestOverride" value="true"/>
        <!--允许重写Session属性-->
        <property name="allowSessionOverride" value="true"/>
        <!--设置request Attribute添加到模型-->
        <property name="exposeRequestAttributes" value="true"/>
        <!--设置session Attribute添加到模型-->
        <property name="exposeSessionAttributes" value="true"/>
        <!--页面内容类型-->
        <property name="contentType" value="text/html;charset=utf-8"/>
    </bean>

</beans>

四、FreeMarker配置：

##freemarker-var.properties 也可以在mvc配置文件中直接写死
root=/

1. web.xml配置

   <?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"
            xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
            version="4.0">
   
       <!--spring配置-->
       <context-param>
           <param-name>contextConfigLocation</param-name>
           <param-value>classpath:applicationContext.xml</param-value>
       </context-param>
       <listener>
           <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
       </listener>
   
       <!--springmvc配置-->
       <servlet>
           <servlet-name>springmvc</servlet-name>
           <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
           <init-param>
               <param-name>contextConfigLocation</param-name>
               <param-value>classpath:spring-servlet.xml</param-value>
           </init-param>
       </servlet>
       <servlet-mapping>
           <servlet-name>springmvc</servlet-name>
           <url-pattern>/</url-pattern>
       </servlet-mapping>
   
       <!--乱码过滤器配置-->
       <filter>
           <filter-name>encodingFilter</filter-name>
           <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
           <init-param>
               <param-name>encoding</param-name>
               <param-value>UTF-8</param-value>
           </init-param>
           <init-param>
               <param-name>forceRequestEncoding</param-name>
               <param-value>true</param-value>
           </init-param>
           <init-param>
               <param-name>forceResponseEncoding</param-name>
               <param-value>true</param-value>
           </init-param>
       </filter>
       <filter-mapping>
           <filter-name>encodingFilter</filter-name>
           <url-pattern>/*</url-pattern>
       </filter-mapping>
   </web-app>
   

最后在指定目录下创建html文件，将后缀改为ftl，然后写一个Controller 请求访问即可。
