Maven 工程整合 Spring mvc + Mybatis +Velocity

1. 創建 maven web 工程，添加依賴

2. 將 maven web 工程設置成 servlet 3.0 項目

詳見：http://blog.csdn.net/u011310774/article/details/48338225

	<diskStore path="java.io.tmpdir" />
	<!-- <diskStore path="D:/cache" />   -->
	
	<!-- 默認配置 -->
	<!-- <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的唯一標識
    maxElementsInMemory：內存中最大緩存對象數
    maxElementsOnDisk：磁盤中最大緩存對象數，若是0表示無窮大
    eternal：Element是否永久有效，一但設置了，timeout將不起作用
    overflowToDisk：配置此屬性，當內存中Element數量達到maxElementsInMemory時，Ehcache將會Element寫到磁盤中 
    timeToIdleSeconds：設置Element在失效前的允許閒置時間。僅當element不是永久有效時使用，可選屬性，默認值是0，也就是可閒置時間無窮大 
    timeToLiveSeconds：設置Element在失效前允許存活時間。最大時間介於創建時間和失效時間之間。僅當element不是永久有效時使用，默認是0.，也就是element存活時間無窮大  
    diskPersistent：是否緩存虛擬機重啓期數據  
    diskExpiryThreadIntervalSeconds：磁盤失效線程運行時間間隔，默認是120秒 
    diskSpoolBufferSizeMB：這個參數設置DiskStore（磁盤緩存）的緩存區大小。默認是30MB。每個Cache都應該有自己的一個緩衝區 
    memoryStoreEvictionPolicy：當達到maxElementsInMemory限制時，Ehcache將會根據指定的策略去清理內存。默認策略是LRU（最近最少使用）。你可以設置爲FIFO（先進先出）或是LFU（較少使用）

-->vm-toolbox.xml

<?xml version="1.0" encoding="UTF-8" ?>

        <scope>application</scope>
        <class>org.apache.commons.lang.StringUtils</class>
    </tool>
</toolbox>

7. 創建表

CREATE TABLE `wt_banner` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `banner_name` varchar(20) DEFAULT '' COMMENT '導航欄名稱',
  `create_date` int(11) unsigned DEFAULT '0' COMMENT '年月日',
  `create_time` int(11) unsigned DEFAULT '0' COMMENT '時分秒',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

8. 使用 mybatis-generator 工具生成實體類和映射文件，再將文件拷貝到對應目錄下
詳見：http://blog.csdn.net/u011310774/article/details/48269031

9. 使用 Junit 進行單元測試

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" }) //加載配置
public class SpringJunitBaseTest {
	
	@Autowired
	private BannerMapper bannerMapper;
	
	@Test
	public void test() {
		Banner banner = new Banner("首頁",20150910,171230);
		bannerMapper.insert(banner);
	}

}

10. 創建 service 實現類

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;

@Service
public class BannerServiceImpl implements IBannerService {
	@Autowired
	private BannerMapper bannerMapper;
	
	public Banner getBannerById(int id){
		Banner banner = bannerMapper.selectByPrimaryKey(id);
		return banner;
	}
}

11. 創建 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;

@Controller
public class TestController {
	@Autowired
	private IBannerService bannerServiceImpl;
	
	@RequestMapping("/nihao")
	public String m(HttpServletRequest request) {
		Banner banner = bannerServiceImpl.getBannerById(1);
		request.setAttribute("velocity", banner);
		return "index";
	}
}
