Maven 工程整合 Spring mvc + Mybatis +Velocity

1. 创建 maven web 工程，添加依赖

2. 将 maven web 工程设置成 servlet 3.0 项目

3. 添加 spring 配置文件

--> spring.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:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"><!-- 引入项目配置文件 --><!-- <context:property-placeholder location="classpath:config.properties" /> --><beanclass="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="locations"><list><value>classpath:config.properties</value></list></property></bean><!-- 自动扫描dao和service包(自动注入) --><context:component-scanbase-package="com.danguiedu.wantuo.dao,com.danguiedu.wantuo.service" /><!-- 默认的注解映射的支持 --><context:annotation-config /><!-- 导入其它 spring 配置文件 --><import resource="spring-mybatis.xml" /><import resource="spring-ehcache.xml" /></beans>

--> spring-mybatis.xml

6. 其它相关配置文件
-->config.properties

-->ehcache.xml

<?xml version="1.0" encoding="UTF-8"?><ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="true" monitoring="autodetect" dynamicConfig="true"><diskStore path="java.io.tmpdir" /><!-- <diskStore path="D:/cache" />   --><!-- 默认配置 --><!-- <defaultCache overflowToDisk="true" eternal="false"/>  --> <defaultCache maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true" maxElementsOnDisk="10000000" diskPersistent="false" diskExpiryThreadIntervalSeconds="120" memoryStoreEvictionPolicy="LRU" /><!--      name：Cache的唯一标识    maxElementsInMemory：内存中最大缓存对象数    maxElementsOnDisk：磁盘中最大缓存对象数，若是0表示无穷大    eternal：Element是否永久有效，一但设置了，timeout将不起作用    overflowToDisk：配置此属性，当内存中Element数量达到maxElementsInMemory时，Ehcache将会Element写到磁盘中     timeToIdleSeconds：设置Element在失效前的允许闲置时间。仅当element不是永久有效时使用，可选属性，默认值是0，也就是可闲置时间无穷大     timeToLiveSeconds：设置Element在失效前允许存活时间。最大时间介于创建时间和失效时间之间。仅当element不是永久有效时使用，默认是0.，也就是element存活时间无穷大      diskPersistent：是否缓存虚拟机重启期数据      diskExpiryThreadIntervalSeconds：磁盘失效线程运行时间间隔，默认是120秒     diskSpoolBufferSizeMB：这个参数设置DiskStore（磁盘缓存）的缓存区大小。默认是30MB。每个Cache都应该有自己的一个缓冲区     memoryStoreEvictionPolicy：当达到maxElementsInMemory限制时，Ehcache将会根据指定的策略去清理内存。默认策略是LRU（最近最少使用）。你可以设置为FIFO（先进先出）或是LFU（较少使用）      --><!-- 用户注册个数缓存 --><cache name="registerCountCache" maxElementsInMemory="10000" maxElementsOnDisk="1000" eternal="false" overflowToDisk="true" diskSpoolBufferSizeMB="20" timeToIdleSeconds="600" timeToLiveSeconds="1200" memoryStoreEvictionPolicy="LFU" /><!-- 微信公众账号token有效期2小时 --><cache name="weixinTokenCache" maxElementsInMemory="10000" maxElementsOnDisk="1000" eternal="false" overflowToDisk="true" diskSpoolBufferSizeMB="20" timeToIdleSeconds="7000" timeToLiveSeconds="7000" memoryStoreEvictionPolicy="LFU" /></ehcache>

-->log4j.properties

-->vm-toolbox.xml

<?xml version="1.0" encoding="UTF-8" ?><toolbox>    <xhtml>true</xhtml>    <tool>        <key>stringUtils</key>        <scope>application</scope>        <class>org.apache.commons.lang.StringUtils</class>    </tool></toolbox>

7. 创建表

CREATE TABLE `wt_banner` (  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,  `banner_name` varchar(20) DEFAULT '' COMMENT '导航栏名称',  `create_date` int(11) unsigned DEFAULT '0' COMMENT '年月日',  `create_time` int(11) unsigned DEFAULT '0' COMMENT '时分秒',  PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

8. 使用 mybatis-generator 工具生成实体类和映射文件，再将文件拷贝到对应目录下
    详见：http://blog.csdn.net/u011310774/article/details/48269031

9. 使用 Junit 进行单元测试

package com.danguiedu.wantuo;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.danguiedu.wantuo.dao.website.BannerMapper;import com.danguiedu.wantuo.model.website.Banner;@RunWith(SpringJUnit4ClassRunner.class) //使用 Spring test 框架@ContextConfiguration(locations = { "classpath:spring.xml" }) //加载配置public class SpringJunitBaseTest {@Autowiredprivate BannerMapper bannerMapper;@Testpublic void test() {Banner banner = new Banner("首页",20150910,171230);bannerMapper.insert(banner);}}

10. 创建 service 实现类

package com.danguiedu.wantuo.service.website;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.danguiedu.wantuo.dao.website.BannerMapper;import com.danguiedu.wantuo.model.website.Banner;@Servicepublic class BannerServiceImpl implements IBannerService {@Autowiredprivate BannerMapper bannerMapper;public Banner getBannerById(int id){Banner banner = bannerMapper.selectByPrimaryKey(id);return banner;}}

11. 创建 controller

package com.danguiedu.wantuo.controller;import javax.servlet.http.HttpServletRequest;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import com.danguiedu.wantuo.model.website.Banner;import com.danguiedu.wantuo.service.website.IBannerService;@Controllerpublic class TestController {@Autowiredprivate IBannerService bannerServiceImpl;@RequestMapping("/nihao")public String m(HttpServletRequest request) {Banner banner = bannerServiceImpl.getBannerById(1);request.setAttribute("velocity", banner);return "index";}}

12. 右键工程 -> Run As -> Maven Install 编译打包

13. tomcat 下运行访问
