1.專案骨架建立
一、使用開發工具IDEA,構建Maven專案,然後調整Maven專案結構,使其成為一個標準的web專案：
此處不選擇Maven骨架，直接Next:
輸入專案的相關資訊，直接Finish
專案構建完成後，選擇pom.xml 打包方式為 war
<packaging>war</packaging>選擇1，建立專案的webapp目錄，選擇2，在指定目錄的WEB-INF下建立web.xml檔案：
專案最終構建完成結構層次圖:
2.整合SSM + FreeMarker:
一、資料庫資原始檔配置：
# 資料庫配置檔案 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配置檔案，配置註解掃描，使用過濾器不掃描Controller註解--> <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> <!--載入外部資源--> <context:property-placeholder location="classpath:db.properties" /> <!--資料來源配置--> <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資源載入多路徑配置--> <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> <!--事務配置--> <!-- 配置事務管理器 --> <bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager" id="transactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!--定義屬性，宣告事務規則 --> <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> <!--定義切面--> <aop:config> <aop:pointcut id="pc1" expression="execution(* org.taoguoguo.meeting.service.*.*(..))"/> <!-- 將事務增強與切入點組合（織入事務切面） --> <aop:advisor advice-ref="txAdvice" pointcut-ref="pc1" /> </aop:config> <!--註解方式配置事務 <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配置檔案 只掃描Controller註解--> <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> <!--註解驅動 HandlereMapping & HandlerAdapter--> <mvc:annotation-driven /> <!--靜態資源放行--> <mvc:resources mapping="/**" location="/" /> <!--載入外部資原始檔--> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <value>classpath:freemarker-var.properties</value> </list> </property> </bean> <!--配置模板基本屬性--> <bean class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer" id="freeMarkerConfigurer"> <!--模板檔案位置--> <property name="templateLoaderPath" value="/WEB-INF/ftl/"/> <!--預設編碼格式--> <property name="defaultEncoding" value="UTF-8" /> <!--全域性變數設定--> <property name="freemarkerVariables"> <map> <entry key="root" value="${root}" /> </map> </property> <!--基本格式配置：時間格式、數字格式--> <property name="freemarkerSettings"> <props> <!--模版的快取時間，單位是s，超過快取時間則從磁碟載入最新的模版--> <prop key="template_update_delay">10</prop> <!--設定預設地區，主要影響數字、日期輸出格式，request中沒有指定地區時模板查詢的值--> <prop key="locale">zh_CN</prop> <!--設定日期時間的輸出格式。--> <prop key="datetime_format">yyyy-MM-dd HH:mm:ss </prop> <!--設定日期的輸出格式--> <prop key="date_format">yyyy-MM-dd</prop> <!--設定時間的輸出格式--> <prop key="time_format">HH:mm:ss</prop> <!--設定數字的輸出格式--> <prop key="number_format">#.####</prop> </props> </property> </bean> <!--freemarker檢視解析器配置--> <bean class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver"> <!--檢視解析器類--> <property name="viewClass" value="org.springframework.web.servlet.view.freemarker.FreeMarkerView" /> <!--字尾配置--> <property name="suffix" value=".ftl"/> <!--設定各種屬性覆蓋--> <!--允許重寫Request屬性--> <property name="allowRequestOverride" value="true"/> <!--允許重寫Session屬性--> <property name="allowSessionOverride" value="true"/> <!--設定request Attribute新增到模型--> <property name="exposeRequestAttributes" value="true"/> <!--設定session Attribute新增到模型--> <property name="exposeSessionAttributes" value="true"/> <!--頁面內容型別--> <property name="contentType" value="text/html;charset=utf-8"/> </bean> </beans>
四、FreeMarker配置：
##freemarker-var.properties 也可以在mvc配置檔案中直接寫死
root=/
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> <!--亂碼過濾器配置--> <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>
最後在指定目錄下建立html檔案，將字尾改為ftl，然後寫一個Controller 請求訪問即可。
