2.项目名称自定义，以springmybatis为例，点击Finish。
3.目录结构如下
4. 调整目录结构 选择当前项目，右键New->Folder，添加lib目录
选择当前项目，右键New->Source Folder，添加resources
修改目录结构如下:
5.lib目录下添加jar包，jar获取可以从http://mvnrepository.com/maven仓库获取, 选中jar包右键，Build Path->Add To Build Path
6.src目录下添加源码jar包目录结构
7.添加源码 包名:com.dillyant.model 类文件名:User.java package com.dillyant.model; public class User { private Integer id ; private String userName ; private String password ; private Integer age ; public Integer getId() { return id ; } public void setId(Integer id ) { this . id = id ; } public String getUserName() { return userName ; } public void setUserName(String userName ) { this . userName = userName == null ? null : userName .trim(); } public String getPassword() { return password ; } public void setPassword(String password ) { this . password = password == null ? null : password .trim(); } public Integer getAge() { return age ; } public void setAge(Integer age ) { this . age = age ; } } 包名:com.dillyant.dao 类文件名:UserMapper.java package com.dillyant.dao; import com.dillyant.model.User; public interface UserMapper { User selectByPrimaryKey(Integer id ); } 包名: com.dillyant.dao XML文件名:UserMapper.xml <? 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.dillyant.dao.UserMapper" > < select id = "selectByPrimaryKey" parameterType = "java.lang.Integer" resultType = "com.dillyant.model.User" > select id, user_name, password, age from user_t where id = #{id,jdbcType=INTEGER} </ select > </ mapper > 包名: com.dillyant.service 类文件名:IUserService.java package com.dillyant.service; import com.dillyant.model.User; public interface IUserService { public User getUserById( int userId ); } 包名: com.dillyant.service.impl 类文件名:UserServiceImpl.java package com.dillyant.service.impl; import javax.annotation.Resource; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import com.dillyant.dao.UserMapper; import com.dillyant.model.User; import com.dillyant.service.IUserService; @Service ( "userService" ) @Transactional(readOnly=false) public class UserServiceImpl implements IUserService { @Resource private UserMapper userMapper; @Override public User getUserById(int userId) { return this.userMapper.selectByPrimaryKey(userId); } } 包名: com.dillyant.main 类文件名:Main.java package com.dillyant.main; import org.apache.log4j.Logger; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.alibaba.fastjson.JSON; import com.dillyant.model.User; import com.dillyant.service.impl.UserServiceImpl; public class Main { private static Logger logger = Logger.getLogger(Main. class ); private static ApplicationContext ac ; public static void main(String[] args ) { ac = new ClassPathXmlApplicationContext( "spring-mybatis.xml" ); UserServiceImpl iuser = (UserServiceImpl) ac .getBean( "userService" ); User user = iuser .getUserById(1); logger .info(JSON.toJSONString( user )); } } 8 resouces目录下添加配置文件 目录结构如下：
数据库配置文件 jdbc.properties driver= com.mysql.jdbc.Driver url= jdbc:mysql://127.0.0.1:3306/yanwftest username=test password= test #定义初始连接数 initialSize= 0 #定义最大连接数 maxActive= 20 #定义最大空闲 maxIdle= 20 #定义最小空闲 minIdle= 1 #定义最长等待时间 maxWait= 60000 日志配置文件 log4j.properties #定义LOG输出级别 log4j.rootLogger= debug,Console,File #定义日志输出目的地为控制台 log4j.appender.Console= org.apache.log4j.ConsoleAppender log4j.appender.Console.Target= System.out #可以灵活地指定日志输出格式，下面一行是指定具体的格式 log4j.appender.Console.layout = org.apache.log4j.PatternLayout log4j.appender.Console.layout.ConversionPattern= [%c] - %m%n #文件大小到达指定尺寸的时候产生一个新的文件 log4j.appender.File = org.apache.log4j.RollingFileAppender #指定输出目录 log4j.appender.File.File = logs/sm.log #定义文件最大大小 log4j.appender.File.MaxFileSize = 10MB # 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志 log4j.appender.File.Threshold = ALL log4j.appender.File.layout = org.apache.log4j.PatternLayout log4j.appender.File.layout.ConversionPattern = [%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n spring mybatis集成配置文件 spring-mybatis.xml <? xml version = "1.0" encoding = "UTF-8" ?> < beans xmlns = "http://www.springframework.org/schema/beans" xmlns:aop = "http://www.springframework.org/schema/aop" xmlns:tx = "http://www.springframework.org/schema/tx" xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" xmlns:mybatis = "http://mybatis.org/schema/mybatis-spring" xmlns:context = "http://www.springframework.org/schema/context" xsi:schemaLocation = "http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd http://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd" > <!-- 自动扫描 --> < context:component-scan base-package = "com.dillyant.service.impl" /> <!-- 引入配置文件 --> < context:property-placeholder location = "classpath:jdbc.properties" /> < bean id = "dataSource" class = "org.apache.commons.dbcp.BasicDataSource" destroy-method = "close" > < property name = "driverClassName" value = "${driver}" /> < property name = "url" value = "${url}" /> < property name = "username" value = "${username}" /> < property name = "password" value = "${password}" /> <!-- 初始化连接大小 --> < property name = "initialSize" value = "${initialSize}" ></ property > <!-- 连接池最大数量 --> < property name = "maxActive" value = "${maxActive}" ></ property > <!-- 连接池最大空闲 --> < property name = "maxIdle" value = "${maxIdle}" ></ property > <!-- 连接池最小空闲 --> < property name = "minIdle" value = "${minIdle}" ></ property > <!-- 获取连接最大等待时间 --> < property name = "maxWait" value = "${maxWait}" ></ property > </ bean > <!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 --> < bean id = "sqlSessionFactory" class = "org.mybatis.spring.SqlSessionFactoryBean" > < property name = "dataSource" ref = "dataSource" /> <!-- 自动扫描mapping.xml文件 --> < property name = "mapperLocations" value = "classpath:com/dillyant/dao/*.xml" ></ property > </ bean > <!-- DAO接口所在包名，Spring会自动查找其下的类 --> < bean class = "org.mybatis.spring.mapper.MapperScannerConfigurer" > < property name = "basePackage" value = "com.dillyant.dao" /> < property name = "sqlSessionFactoryBeanName" value = "sqlSessionFactory" ></ property > </ bean > <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --> < bean id = "transactionManager" class = "org.springframework.jdbc.datasource.DataSourceTransactionManager" > < property name = "dataSource" ref = "dataSource" /> </ bean > <!-- 在Spring中使用基于注解的事务管理特性 --> < tx:annotation-driven transaction-manager = "transactionManager" proxy-target-class = "true" /> </ beans > 9。运行测试成功。
10。导出可执行jar包 选中项目，右键Export,选择Runnable JAR file
Launch configuration选择当前项目的main， Export destination自定义， Library handling选择第三项，其他两项测试都未通过。
导出目录结果如下：
(windows 平台) 使用java 命令执行该jar包，如下：
结果如下，测试通过。
linux 平台 使用java 命令执行该jar包，如下：
结果如下，测试通过。
