基于Maven的Spring + Spring MVC + Mybatis的環(huán)境搭建項(xiàng)目開發(fā)，先將環(huán)境先搭建起來(lái)凤藏。上次做了一個(gè)Spring + Spring MVC + Mybatis + Log4J + JUnit Test的環(huán)境搭建，這次也差不多嗡善，不過(guò)就是基于了Maven岗宣，同時(shí)也添加了事務(wù)管理热某。
首先，可以去了解一下maven园细，個(gè)人覺得這個(gè)東西就是JAR包管理方便惦积，不用自己一個(gè)個(gè)去寫，直接添加dependence就行了猛频，不過(guò)有時(shí)候要注意喲狮崩，有可能重復(fù)的包含了某個(gè)JAR包，會(huì)報(bào)沖突的喲鹿寻，親睦柴！因?yàn)橹挥幸粋€(gè)POM文件里指定JAR包，所以整個(gè)項(xiàng)目都很小的毡熏，一般就幾MB坦敌，只有你在將該項(xiàng)目打成WAR包的時(shí)候，maven會(huì)自動(dòng)的把三方JAR包放進(jìn)項(xiàng)目痢法，然后你就可以去部署到Tomcat的webapp下面了狱窘，放進(jìn)去，重啟Tomcat就OK财搁。
1.開始搭建我的環(huán)境吧浮定。首先邻邮，IDE我用的是eclipse的JEE版本休傍。要保證裝上了Maven喲沪悲，可以使用eclipse的Install New Software穷当，
URL地址是http://m2eclipse.sonatype.org/sites/m2e/，
然后一步步走下去淹禾，安裝好了過(guò)了會(huì)重啟一次膘滨。給一個(gè)忠告喲，安裝好了maven后稀拐，不要使用IDE里面的了，而是去官方下載一個(gè)丹弱，解壓德撬，然后讓IDE的Maven指向你下載安裝的，如圖：
2.maven安裝成功了躲胳，我們用Maven創(chuàng)建一個(gè)新的WEB項(xiàng)目蜓洪。File—> New—> Other—>Maven Project.
選默認(rèn)，下一步坯苹。在Select an Archetype里面種找到如下圖所示
3.然后next隆檀，輸入groupId:net.yuanmomo；artifactId:Test粹湃，然后finish恐仑，稍微等待一下，就創(chuàng)建好了为鳄。下面的是創(chuàng)建好了的一個(gè)初始的項(xiàng)目：
4.但是這個(gè)并不是默認(rèn)的maven項(xiàng)目的標(biāo)準(zhǔn)結(jié)構(gòu).我們需要進(jìn)行一些改動(dòng).
(1).在項(xiàng)目下創(chuàng)建一個(gè)Source Folder.
Folder Name:src/main/java
如下圖所示:
(當(dāng)然,還可以添加用于junit測(cè)試的src/test/java和src/test/resources
不過(guò)在此就不添加了.)
(2).在src/main/java中創(chuàng)建3個(gè)包(maven標(biāo)準(zhǔn)推薦是3層包結(jié)構(gòu))
(3).如果裝的JDK是1.6的,更改JRE System Libary為1.6版本的.
(4).就src/main/webapp文件夾看做一個(gè)的WebRoot,然后創(chuàng)建js,css,jsp等文件夾裳仆。
這樣.一個(gè)標(biāo)準(zhǔn)的maven web項(xiàng)目創(chuàng)建成功.
5.大家一看上面的項(xiàng)目結(jié)構(gòu)，很熟悉吧孤钦。maven的項(xiàng)目結(jié)構(gòu)路徑有點(diǎn)討厭歧斟，有點(diǎn)讓人很煩。maven打WAR包的時(shí)候提取的東西是src/main/webapp下面的文件偏形，然后打成一個(gè)WAR的WEB項(xiàng)目就可以部署了静袖，但是，但是俊扭，我們?cè)陂_發(fā)的時(shí)候队橙，在使用eclipse里面的Tomcat調(diào)試的時(shí)候，tomcat卻不是把src/main/webapp下面的文件部署到服務(wù)器萨惑。此時(shí)喘帚，如果你打開Server,然后add and remove，你在左邊是找不到Test項(xiàng)目的咒钟，如下：
原因是因?yàn)門omcat默認(rèn)回去Test項(xiàng)目的路徑下面去找WebRoot—>WEB-INF–>web.xml(WebRoot文件夾的名字可以不一樣吹由，可以使其它的，但是WEB-INF–>web.xml這兩個(gè)名字不能變)朱嘴，但是當(dāng)前就找不到這幾個(gè)目錄倾鲫。這個(gè)時(shí)候有兩個(gè)解決辦法：
(5.1). 在Test項(xiàng)目的路徑下面粗合，按照路徑規(guī)則創(chuàng)建WebRoot，WEB-INF等文件夾乌昔，然后把上面的web.xml拷貝到新建的WEB-INF中去隙疚。放心吧，我上一個(gè)項(xiàng)目就是這樣做的磕道，不過(guò)這種方式打死都不可取的供屉。你修改JSP的時(shí)候改的是下面的，maven打包的時(shí)候用的上面的溺蕉。你還得拷貝過(guò)來(lái)伶丐，拷過(guò)去，麻煩疯特，如果再有svn管理哗魂，累死你，暈死你漓雅，我們經(jīng)常是調(diào)試編寫的時(shí)候再下面做录别，最后提交的時(shí)候還得一個(gè)個(gè)拷貝上去，還出很多問題邻吞。所以建議采用第二種方式组题。
(5.2).轉(zhuǎn)換該項(xiàng)目:
(1)在Test工程名上右鍵–>Properties–>Project Facets–>Convet to faceted form,
(2)勾上Dynamic Web Module,選擇2.4版本。同時(shí)點(diǎn)擊下方的further configuration available
(3)將默認(rèn)的WebContent改成src/main/webapp
(4)一路點(diǎn)OK..此時(shí)在server視圖中的tomcat server上點(diǎn)右鍵–>Add and Remove抱冷，就能看到該項(xiàng)目于往踢，然后部署啦。
至此徘层，我們已經(jīng)創(chuàng)建好了一個(gè)合格的基于Maven的項(xiàng)目峻呕，也可以在Tomcat中部署。
接下來(lái)趣效，我們開始整合我們的J2EE框架瘦癌。
6.先給出數(shù)據(jù)庫(kù)的創(chuàng)建腳本，方便測(cè)試搭建是否成功跷敬。
SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";
—
— 數(shù)據(jù)庫(kù): `timesheet`
—
CREATE DATABASE `timesheet` DEFAULT CHARACTER SET utf8 COLLATE utf8_bin;
USE `timesheet`;
— ——————————————————–
—
— 表的結(jié)構(gòu) `testtable`
—
CREATE TABLE IF NOT EXISTS `testtable` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(50) COLLATE utf8_bin DEFAULT NULL,
`date` timestamp NULL DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin AUTO_INCREMENT=1 ;
7.在pom文件中添加必要的jar包的dependence讯私，可以從兩個(gè)地方查詢：
http://mvnrepository.com/
http://search.maven.org/
添加后的pom文件如下：

修改pom文件后，保存饺鹃，maven會(huì)自動(dòng)的去download這些jar包到本地莫秆。等待的時(shí)間可能會(huì)很長(zhǎng)间雀。上面我把所有我這次項(xiàng)目用到的包都羅列出來(lái)了，如果你用不到的镊屎，可以自行刪除惹挟。
下載完成過(guò)后，點(diǎn)開項(xiàng)目左側(cè)的Maven Dependencies缝驳，你就能看到很多的下載的JAR包了连锯。
8. 修改web.xml，配置Spring用狱，spring MVC运怖，log4j，亂碼處理等齿拂。
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <!– Spring context startup Spring的初始化–> <context-param> <param-name>contextConfigLocation</param-name> <param-value><!– Spring的配置文件 –> classpath:/com/comverse/timesheet/config/ApplicationContext.xml </param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <!– Spring character filter 處理亂碼–> <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> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!– Configuration of Log4j log4j的配置 –> <context-param> <param-name>log4jConfigLocation</param-name> <param-value><!– log4j.properties文件路徑 –> classpath:/com/comverse/timesheet/config/log4j.properties </param-value> </context-param> <context-param> <param-name>log4jRefreshInterval</param-name> <param-value>60000</param-value> </context-param> <listener> <listener-class> org.springframework.web.util.Log4jConfigListener </listener-class> </listener> <!– Spring MVC Configuration Spring MVC的配置–> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value><!– dispatcher-servlet.xml文件路徑 –> classpath:/com/comverse/timesheet/config/dispatcher-servlet.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> </web-app>
修改后保存該文件。
9.添加 log4j.properties,jdbc.properties等配置文件：
路徑位置：
各個(gè)配置文件的內(nèi)容如下：
(1). log4j.properties: log4j的配置

此時(shí)医男，幾個(gè)主要的配置文件我們已經(jīng)加進(jìn)來(lái)了砸狞，只有mybatis還有幾個(gè)配置文件沒有加進(jìn)來(lái)。
10. 創(chuàng)建包镀梭，用于開發(fā)系統(tǒng)：
bean : 放pojo, java bean

package com.comverse.timesheet.web.impl;import com.comverse.timesheet.web.bean.TestTable; import com.comverse.timesheet.web.dao.ITestTableDAO; import com.comverse.timesheet.web.util.BasicSqlSupport;public class ITestTableDAOImpl extends BasicSqlSupport implements ITestTableDAO { @Override public boolean add(TestTable test) throws Exception { boolean flag=false; int count=this.session.insert("com.comverse.timesheet.web.mapper.Test.add",test); if(count>0){ flag=true; } return flag; } }
(4). business: TestBusiness.java
package com.comverse.timesheet.web.business;import java.util.Date;import javax.annotation.Resource;import org.springframework.transaction.annotation.Transactional;import com.comverse.timesheet.web.bean.TestTable; import com.comverse.timesheet.web.dao.ITestTableDAO;public class TestBusiness { private ITestTableDAO testDAO=null; public ITestTableDAO getTestDAO() { return testDAO; } public void setTestDAO(ITestTableDAO testDAO) { this.testDAO = testDAO; } public void add() throws Exception{ TestTable test=new TestTable(); test.setName("yuanmomo6"); test.setBirthday(new Date()); try { testDAO.add(test); } catch (Exception e) { // TODO Auto-generated catch block throw e; } } }
(5). Controller : ResultController
package com.comverse.timesheet.web.controller;import javax.annotation.Resource; import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Controller; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.RequestMapping;import com.comverse.timesheet.web.business.TestBusiness;@Controller @RequestMapping("/result.do") public class ResultController { //將spring 配置文件中的bean 通過(guò)setter注入進(jìn)來(lái) @Resource(name="TestBusiness") private TestBusiness testBusiness=null; public void setTestBusiness(TestBusiness testBusiness) { this.testBusiness = testBusiness; } @RequestMapping public String viewUser(HttpServletRequest request, ModelMap modelMap) throws Exception { System.out.println("$$$$$$$$$$$$$$$$$$$$$you want to check the result.jsp+++++++++++++"); System.out.println("$$$$$$$$$$$$$$$$$$$$$ ready to insert +++++++++++++"); testBusiness.add(); System.out.println("$$$$$$$$$$$$$$$$$$$$$ insert completed +++++++++++++"); return "result"; } }
(6). util : BasicSqlSupport.java所有的implementation類都會(huì)繼承這個(gè)類榜晦，在ImplAndBusinessBeans.xml文件中注冊(cè)的bean,都會(huì)注入一個(gè)sqlsession。例如上面的implementation就是繼承了這個(gè)類羽圃。
package com.comverse.timesheet.web.util;import org.apache.ibatis.session.SqlSession;public class BasicSqlSupport{ protected SqlSession session; public SqlSession getSession() { return session; } public void setSession(SqlSession session) { this.session = session; } }

加入mybatis的配置文件：
(1). 為 TestTable bean 創(chuàng)建mapper文件乾胶，路徑為com/comverse/timesheet/mybatis/mapper/Test.xml:
Test.xml<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN" "http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd"> <mapper namespace="com.comverse.timesheet.web.mapper.Test"> <!– 定義一條查詢語(yǔ)句，在bean的implementation中會(huì)引用此語(yǔ)句的id –> <insert id="add" parameterType="Test" useGeneratedKeys="true" keyProperty="classId"> INSERT INTO testtable (NAME,DATE) VALUES(#{name},#{birthday}) </insert> </mapper>
(1). 加入Mybatis的配置文件：在上面的ApplicationContext.xml文件中我們已經(jīng)包含了SqlMapConfig.xml文件朽寞。在/com/comverse/timesheet/mybatis/下創(chuàng)建
SqlMapConfig.xml:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//ibatis.apache.org//DTD Config 3.0//EN" "http://ibatis.apache.org/dtd/ibatis-3-config.dtd"> <configuration> <typeAliases> <!– Entities 參數(shù)實(shí)體 –> <!– com.comverse.timesheet.web.bean 包中的 所有Bean, 取個(gè)別名 –> <!– 比如TestTable類就用Test來(lái)表示–> <typeAlias type="com.comverse.timesheet.web.bean.TestTable" alias="Test" /> </typeAliases> <mappers> <!– 對(duì)應(yīng)Bean類的xml配置文件的路徑信息 –> <mapper resource="com/comverse/timesheet/mybatis/mapper/Test.xml" /> </mappers> </configuration>

框架的整合完成识窿，項(xiàng)目的目錄結(jié)構(gòu)如下：
在這里插入圖片描述 -
編寫一個(gè)測(cè)試頁(yè)面，這個(gè)頁(yè)面的路徑在dispatcher-servlet.xml中已經(jīng)確定—/WEB-INF/jsp/：
文件名在controller中已經(jīng)定義–result, 后綴是 .jsp, 所以就是 result.jsp脑融。
在這里插入圖片描述
(1). result.jsp:
<%@page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Insert title here</title> </head> <body> <h1> 你插入數(shù)據(jù)成功了Ｓ髌怠！肘迎！</h1> </body> </html>
14.至此半抱，我們的項(xiàng)目完成了脓恕，部署。
部署之前檢查一下problem框窿侈，看有沒有問題炼幔。這次我突然遇到一個(gè)問題，我上個(gè)星期五的時(shí)候都沒有遇到史简，今天就奇了怪了乃秀。不過(guò)沒事，問題來(lái)就想辦法解決它圆兵。
(1).在problem處發(fā)現(xiàn)這個(gè)問題
Description：
Classpath entry org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER will not be exported or published. Runtime ClassNotFoundExceptions may result. 如果部署了項(xiàng)目跺讯，啟動(dòng)，會(huì)報(bào)找不到類異常殉农。
(2).問題的原因參考 Loose classpath web libraries support
在項(xiàng)目上右鍵–>properties—>deployment Assembly–>add,選擇 java build path entries刀脏，然后選中Maven dependencies–>finish–>OK,就能解決問題啦。
- 一點(diǎn)小插曲過(guò)后超凳，我們?cè)俅蔚牟渴痦?xiàng)目愈污，重新啟動(dòng)，看日志轮傍，項(xiàng)目成功的啟動(dòng)起來(lái)啦暂雹。
