Freemark与Spring MVC的整合

1、项目的视图存放位置

2、整合Spring MVC 的配置，web.xml的配置如下

<?xml version="1.0" encoding="UTF-8"?><web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"><display-name></display-name><!-- 加载spring容器 --><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前端控制器 --><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:springmvc.xml</param-value></init-param></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>*.action</url-pattern></servlet-mapping><!--主页的配置 --><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list></web-app>

2、FreeMarker与SpringMVC整合，首先，在springmvc的配置文件普通视图之前，加入freemarker的视图。Spring MVC的配置文件，

springmvc.xml

<?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:mvc="http://www.springframework.org/schema/mvc"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-3.2.xsd         http://www.springframework.org/schema/mvc         http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd         http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-3.2.xsd         http://www.springframework.org/schema/aop         http://www.springframework.org/schema/aop/spring-aop-3.2.xsd         http://www.springframework.org/schema/tx         http://www.springframework.org/schema/tx/spring-tx-3.2.xsd "><!-- 可以扫描controller、service、... 这里让扫描controller，指定controller的包 --><context:component-scan base-package="com.controller"></context:component-scan><!--静态资源的处理 --><mvc:resources location="/resources/" mapping="/resources/**" /><!--mvc的注解开发 --><mvc:annotation-driven></mvc:annotation-driven><!-- freemarker config --><bean id="freemarkerConfig"class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer"><property name="templateLoaderPath" value="/WEB-INF/ftl/" /><!-- 设置FreeMarker环境属性 --><property name="freemarkerSettings"><props><!--刷新模板的周期，单位为秒 --><prop key="template_update_delay">20</prop><!--模板的编码格式 --><prop key="default_encoding">UTF-8</prop><!--本地化设置 --><prop key="locale">UTF-8</prop><prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop><prop key="time_format">HH:mm:ss</prop><prop key="number_format">0.####</prop><prop key="boolean_format">true,false</prop><prop key="whitespace_stripping">true</prop><prop key="tag_syntax">auto_detect</prop><prop key="url_escaping_charset">UTF-8</prop></props></property></bean><!-- View resolvers can also be configured with ResourceBundles or XML files.

3、Spring相关配置文件的加载

      3.1 db.properties

jdbc.driver=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/studentjdbc.username=rootjdbc.password=1234

      3.2 applicationContext-dao.xml

<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"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-3.2.xsd         http://www.springframework.org/schema/mvc         http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd         http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-3.2.xsd         http://www.springframework.org/schema/aop         http://www.springframework.org/schema/aop/spring-aop-3.2.xsd         http://www.springframework.org/schema/tx         http://www.springframework.org/schema/tx/spring-tx-3.2.xsd "><!-- 加载db.properties文件中的内容，db.properties文件中key命名要有一定的特殊规则 --><context:property-placeholder location="classpath:db.properties" /><!-- 配置数据源,dbcp --><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"destroy-method="close"><property name="driverClassName" value="${jdbc.driver}" /><property name="url" value="${jdbc.url}" /><property name="username" value="${jdbc.username}" /><property name="password" value="${jdbc.password}" /><property name="maxActive" value="30" /><property name="maxIdle" value="5" /></bean><!-- sqlSessionFactory --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><!-- 数据库连接池 --><property name="dataSource" ref="dataSource" /><!-- 加载mybatis的全局配置文件 --><property name="configLocation" value="classpath:sqlMapConfig.xml" /></bean><!-- mapper扫描器 --><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><!-- 扫描包路径，如果需要扫描多个包，中间使用半角逗号隔开 --><property name="basePackage" value="com.mapper"></property><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property></bean></beans>

      3.4 applicationContext-service.xml

<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"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-3.2.xsd         http://www.springframework.org/schema/mvc         http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd         http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-3.2.xsd         http://www.springframework.org/schema/aop         http://www.springframework.org/schema/aop/spring-aop-3.2.xsd         http://www.springframework.org/schema/tx         http://www.springframework.org/schema/tx/spring-tx-3.2.xsd "><context:spring-configured /><!--扫描Service的package --><context:component-scan base-package="com.service" /></beans>

4、Mybatis相关的配置文件

      4.1 sqlMapConfig.xml

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration><!-- 全局setting配置 ，根据需要再添加 --><!-- 配置别名 --><typeAliases><!-- 批量扫描别名 --><package name="com.entity" /></typeAliases><!-- 配置mapper 由于使用spring和mybatis的整合包进行整合，这了无需配置 但必须遵循：mapper.java和mapper.xml文件同名且在同一目录 --><!--<mappers></mappers> --></configu

      4.2 NavMapper.xml

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd"><!-- namespace命名空间，作用就是对sql进行分类化管理，理解sql隔离 注意：使用mapper代理方法开发，namespace有特殊重要的作用 --><mapper namespace="com.mapper.NavMapper"><select id="findNavById" parameterType="int" resultType="nav">SELECT*FROM nav WHERE id=#{id}</select><select id="findAll" resultType="nav">SELECT* FROMnav</select><insert id="add" parameterType="nav">insert into nav(name)values(#{name})</insert><update id="update" parameterType="nav">update nav set name=#{name}where id=#{id}</update><delete id="delete" parameterType="int">delete from nav where id=#{id}</delete></mapper>

      4.3 NavMapper.java与NavMapper.xml

5、log4j相关的配置文件

# Global logging configurationlog4j.rootLogger=DEBUG, stdout# Console output...log4j.appender.stdout=org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.layout=org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

6、关于页面的放置

7、NavController的实现

import java.util.List;import java.util.Map;import javax.annotation.Resource;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import com.entity.Nav;import com.service.NavService;@Controller@RequestMapping("/navController")public class NavController {@Resourceprivate NavService navService;public void setNavService(NavService navService) {this.navService = navService;}@RequestMapping("/jsp")public String toJspPage() {return "index";}@RequestMapping("/freemark")public String toFreemarkPage(Map<String, Object> model) {List<Nav> navs = navService.findAll();model.put("navs", navs);return "top";}}

8、访问测试

9、源码下载
