        摘要：本文主要講了如何使用Maven來搭建Spring+Mybatis+MySql的的搭建執行個體，文章寫得很詳細，有代碼有圖片，最後也帶有啟動並執行效果。

一、準備工作

1. 首先建立一個表：

CREATE TABLE `t_user` (  `USER_ID` int(11) NOT NULL AUTO_INCREMENT,  `USER_NAME` char(30) NOT NULL,  `USER_PASSWORD` char(10) NOT NULL,  `USER_EMAIL` char(30) NOT NULL,  PRIMARY KEY (`USER_ID`),  KEY `IDX_NAME` (`USER_NAME`)) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8

隨便插入一些資料：

INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (1, ‘林炳文‘, ‘[email protected]‘, ‘[email protected]‘);INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (2, ‘evan‘, ‘123‘, ‘[email protected]‘);INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (3, ‘kaka‘, ‘cadg‘, ‘[email protected]‘);INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (4, ‘simle‘, ‘cscs‘, ‘[email protected]‘);INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (5, ‘arthur‘, ‘csas‘, ‘[email protected]‘);INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (6, ‘小德‘, ‘yuh78‘, ‘[email protected]‘);INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (7, ‘小小‘, ‘cvff‘, ‘[email protected]‘);INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (8, ‘林林之家‘, ‘gvv‘, ‘[email protected]‘);INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (9, ‘林炳文Evankaka‘, ‘dfsc‘, ‘[email protected]‘);INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (10, ‘apple‘, ‘uih6‘, ‘[email protected]‘);

二、工程建立

1、Maven工程建立

（1）建立

（2）選擇快速架構

（3）輸出項目名，包，記得選war(表示web項目，以後可以spingMVC連起來用)

（4）建立好之後 

目錄如下：

（5）檢查下

這三個地方JDK的版本一定要一樣！！！！

三、sping+mybatis配置

1、整個工程目錄如下：

2、POM檔案

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.lin</groupId><artifactId>ssm_project</artifactId><version>0.0.1-SNAPSHOT</version><packaging>war</packaging><properties><!-- spring版本號碼 --><spring.version>3.2.8.RELEASE</spring.version><!-- log4j記錄檔管理組件版本 --><slf4j.version>1.6.6</slf4j.version><log4j.version>1.2.12</log4j.version><!-- junit版本號碼 --><junit.version>4.10</junit.version><!-- mybatis版本號碼 --><mybatis.version>3.2.1</mybatis.version></properties><dependencies><!-- 添加Spring依賴 --><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aspects</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>${spring.version}</version></dependency><!--單元測試依賴 --><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>${junit.version}</version><scope>test</scope></dependency><!-- 記錄檔管理組件 --><!-- log start --><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>${log4j.version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId><version>${slf4j.version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>${slf4j.version}</version></dependency><!-- log end --><!--spring單元測試依賴 --><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>${spring.version}</version><scope>test</scope></dependency><!--mybatis依賴 --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>${mybatis.version}</version></dependency><!-- mybatis/spring包 --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.2.0</version></dependency><!-- mysql驅動包 --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.29</version></dependency></dependencies></project>

3、java代碼-------src/main/java

目錄如下：

（1）User.java

對應資料庫中表的欄位，放在src/main/java下的包com.lin.domain

package com.lin.domain;/** * User映射類 *  * @author linbingwen * @time 2015.5.15 */public class User {private Integer userId;private String userName;private String userPassword;private String userEmail;public Integer getUserId() {return userId;}public void setUserId(Integer userId) {this.userId = userId;}public String getUserName() {return userName;}public void setUserName(String userName) {this.userName = userName;}public String getUserPassword() {return userPassword;}public void setUserPassword(String userPassword) {this.userPassword = userPassword;}public String getUserEmail() {return userEmail;}public void setUserEmail(String userEmail) {this.userEmail = userEmail;}@Overridepublic String toString() {return "User [userId=" + userId + ", userName=" + userName+ ", userPassword=" + userPassword + ", userEmail=" + userEmail+ "]";}}

（2）UserDao.java

Dao介面類，用來對應mapper檔案。放在src/main/java下的包com.lin.dao,內容如下：

package com.lin.dao;import com.lin.domain.User;/** * 功能概要：User的DAO類 *  * @author linbingwen * @since 2015年9月28日 */public interface UserDao {/** *  * @author linbingwen * @since 2015年9月28日 * @param userId * @return */public User selectUserById(Integer userId);}

（2）UserService.java和UserServiceImpl.java

service介面類和實作類別，放在src/main/java下的包com.lin.service,內容如下：

UserService.java

package com.lin.service;import org.springframework.stereotype.Service;import com.lin.domain.User;/** * 功能概要：UserService介面類 *  * @author linbingwen * @since  2015年9月28日  */public interface UserService {User selectUserById(Integer userId);}

UserServiceImpl.java

package com.lin.service;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.lin.dao.UserDao;import com.lin.domain.User;/** * 功能概要：UserService實作類別 *  * @author linbingwen * @since  2015年9月28日  */@Servicepublic class UserServiceImpl implements UserService{@Autowiredprivate UserDao userDao;public User selectUserById(Integer userId) {return userDao.selectUserById(userId);}}

（4）mapper檔案

用來和dao檔案對應，放在src/main/java下的com.lin.mapper包下

<?xml version="1.0" encoding="UTF-8"?>  <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"  "http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="com.lin.dao.UserDao"><!--設定domain類和資料庫中表的欄位一一對應，注意資料庫欄位和domain類中的欄位名稱不致，此處一定要！--><resultMap id="BaseResultMap" type="com.lin.domain.User"><id column="USER_ID" property="userId" jdbcType="INTEGER" /><result column="USER_NAME" property="userName" jdbcType="CHAR" /><result column="USER_PASSWORD" property="userPassword" jdbcType="CHAR" /><result column="USER_EMAIL" property="userEmail" jdbcType="CHAR" /></resultMap><!-- 查詢單條記錄 --><select id="selectUserById" parameterType="int" resultMap="BaseResultMap">SELECT * FROM t_user WHERE USER_ID = #{userId}</select></mapper>

4、資源配置-------src/main/resources

目錄如下：

(1)mybatis設定檔

這裡沒有什麼內容，因為都被放到application.xml中去了,放在src/main/resources下的mybatis檔案夾下

mybatis-config.xml內容如下：

<?xml version="1.0" encoding="UTF-8"?>  <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"  "http://mybatis.org/dtd/mybatis-3-config.dtd">  <configuration>    </configuration>

（2）資料來源配置jdbc.properties

放在src/main/resources下的propertiesy檔案夾下

jdbc_driverClassName=com.mysql.jdbc.Driverjdbc_url=jdbc:mysql://localhost:3306/learningjdbc_username=root[email protected]

（3）Spring配置

這是最重要的：application.xml內容如下

<?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:aop="http://www.springframework.org/schema/aop"xsi:schemaLocation="             http://www.springframework.org/schema/beans             http://www.springframework.org/schema/beans/spring-beans-3.0.xsd             http://www.springframework.org/schema/aop             http://www.springframework.org/schema/aop/spring-aop-3.0.xsd           http://www.springframework.org/schema/context             http://www.springframework.org/schema/context/spring-context-3.0.xsd">          <!-- 引入jdbc設定檔 -->       <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">        <property name="locations">            <list>               <value>classpath:properties/*.properties</value>                <!--要是有多個設定檔，只需在這裡繼續添加即可 -->            </list>        </property>    </bean>        <!-- 配置資料來源 --><bean id="dataSource"class="org.springframework.jdbc.datasource.DriverManagerDataSource"><!-- 不使用properties來配置 --><!-- <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/learning" /> <property name="username" value="root" /> <property name="password" value="[email protected]" /> -->   <!-- 使用properties來配置 --><property name="driverClassName"><value>${jdbc_driverClassName}</value></property><property name="url"><value>${jdbc_url}</value></property><property name="username"><value>${jdbc_username}</value></property><property name="password"><value>${jdbc_password}</value></property></bean><!-- 自動掃描了所有的XxxxMapper.xml對應的mapper介面檔案，這樣就不用一個一個手動設定Mpper的映射了，只要Mapper介面類和Mapper對應檔對應起來就可以了。 --><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage"value="com.lin.dao" /></bean>    <!-- 配置Mybatis的檔案 ，mapperLocations配置**Mapper.xml檔案位置，configLocation配置mybatis-config檔案位置--><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource" />        <property name="mapperLocations" value="classpath*:com/lin/mapper/**/*.xml"/>  <property name="configLocation" value="classpath:mybatis/mybatis-config.xml" /><!-- <property name="typeAliasesPackage" value="com.tiantian.ckeditor.model" /> --></bean><!-- 自動掃描註解的bean --><context:component-scan base-package="com.lin.service" /></beans>

（4）日誌列印log4j.properties

就放在src/main/resources

log4j.rootLogger=DEBUG,Console,Stdout#Consolelog4j.appender.Console=org.apache.log4j.ConsoleAppenderlog4j.appender.Console.layout=org.apache.log4j.PatternLayoutlog4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%nlog4j.logger.java.sql.ResultSet=INFOlog4j.logger.org.apache=INFOlog4j.logger.java.sql.Connection=DEBUGlog4j.logger.java.sql.Statement=DEBUGlog4j.logger.java.sql.PreparedStatement=DEBUG log4j.appender.Stdout = org.apache.log4j.DailyRollingFileAppender  log4j.appender.Stdout.File = E://logs/log.log  log4j.appender.Stdout.Append = true  log4j.appender.Stdout.Threshold = DEBUG   log4j.appender.Stdout.layout = org.apache.log4j.PatternLayout  log4j.appender.Stdout.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n  

四、單元測試

上面的配置完好，接下來就是測驗成功

整個目錄 如下：

（1）測試基類

package com.lin.baseTest;import org.junit.runner.RunWith;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;/** * 功能概要： *  * @author linbingwen * @since  2015年9月28日  *///指定bean注入的設定檔@ContextConfiguration(locations = { "classpath:application.xml" })//使用標準的JUnit @RunWith注釋來告訴JUnit使用Spring TestRunner@RunWith(SpringJUnit4ClassRunner.class)public abstract class SpringTestCase extends AbstractJUnit4SpringContextTests{protected Logger logger = LoggerFactory.getLogger(getClass());}

（2）測試類別

package com.lin.service;import org.apache.log4j.Logger;import org.junit.Test;import org.springframework.beans.factory.annotation.Autowired;import com.lin.baseTest.SpringTestCase;import com.lin.domain.User;/** * 功能概要：UserService單元測試 *  * @author linbingwen * @since  2015年9月28日  */public class UserServiceTest extends SpringTestCase{@Autowiredprivate UserService userService;Logger logger = Logger.getLogger(UserServiceTest.class);@Testpublic void selectUserByIdTest(){User user = userService.selectUserById(10);        logger.debug("尋找結果" + user);}}

選中selectUserByIdTest，然後右鍵如下運行

輸出結果：

重要列印的結果

這裡

2015-09-28 15:20:15,129 [main] DEBUG [com.lin.dao.UserDao.selectUserById] - ==>  Preparing: SELECT * FROM t_user WHERE USER_ID = ? 2015-09-28 15:20:15,160 [main] DEBUG [com.lin.dao.UserDao.selectUserById] - ==> Parameters: 10(Integer)2015-09-28 15:20:15,160 [main] DEBUG [org.mybatis.spring.SqlSessionUtils] - Closing non transactional SqlSession [[email protected]]2015-09-28 15:20:15,160 [main] DEBUG [org.springframework.jdbc.datasource.DataSourceUtils] - Returning JDBC Connection to DataSource2015-09-28 15:20:15,160 [main] DEBUG [com.lin.service.UserServiceTest] - 尋找結果User [userId=10, userName=apple, userPassword=uih6, [email protected]]

資料庫：

程式成功運行，並且結果正確！
