在这里，写一下，怎么使用Maven构建MyBatis项目。 ### 1. 新建一个Web项目 可以参考前面的博客 ### 2. 修改pom.xml，添加MyBatis依赖 ~~~ <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/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.deppon.demo</groupId> <artifactId>test05</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>test05 Maven Webapp</name> <url>http://maven.apache.org</url> <!-- 属性配置 --> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.10</version> <scope>test</scope> </dependency> <!-- 添加MyBatis依赖 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.1.1</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.16</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.6.1</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-nop</artifactId> <version>1.6.4</version> </dependency> </dependencies> <build> <finalName>test05</finalName> </build> </project> ~~~ ### 3. 添加mybatis-config.xml ~~~ <?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> <!-- 全局别名设置，在映射文件中只需写别名，而不必写出整个类路径 --> <typeAliases> <typeAlias type="com.deppon.test05.entity.PersonEntity" alias="PersonEntity"/> </typeAliases> <environments default="development"> <environment id="development"> <transactionManager type="JDBC" /> <dataSource type="POOLED"> <property name="driver" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" /> <property name="url" value="jdbc:sqlserver://localhost:1433;DatabaseName=Demo" /> <property name="username" value="ygy" /> <property name="password" value="shishi" /> </dataSource> </environment> </environments> <mappers> <mapper resource="com/deppon/test05/mapper/PersonEntityMapper.xml" /> </mappers> </configuration> ~~~ PersonEntityMapper.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.deppon.test05.mapper.PersonEntityMapper"> <!-- 查询所有用户 --> <select id="queryAll" resultType="PersonEntity" > select * from t_person </select> <!-- 插入一条记录 --> <insert id="insert" parameterType="PersonEntity"> insert into t_person(id , name) values(#{id} , #{name}) </insert> </mapper> ~~~ IPersonEntityDao.java ~~~ package com.deppon.test05.dao; import java.util.List; import com.deppon.test05.entity.PersonEntity; public interface IPersonEntityDao { /** * 插入一条记录 * @param person */ public void insert(PersonEntity person); /** * 查询所有记录 * @return */ public List<PersonEntity> queryAll(); } ~~~ PersonEntityDao.java ~~~ package com.deppon.test05.dao.impl; import java.util.List; import org.apache.ibatis.session.SqlSession; import com.deppon.test05.dao.IPersonEntityDao; import com.deppon.test05.entity.PersonEntity; import com.deppon.test05.util.MyBatisUtil; public class PersonEntityDao implements IPersonEntityDao { public static final String NAMESPACE = "com.deppon.test05.mapper.PersonEntityMapper"; @Override public void insert(PersonEntity person) { SqlSession session = MyBatisUtil.getSession(); session.insert(NAMESPACE + ".insert" , person); session.commit(); session.close(); } @Override public List<PersonEntity> queryAll() { SqlSession session = MyBatisUtil.getSession(); List<PersonEntity> personList = session.selectList(NAMESPACE + ".queryAll"); session.commit(); session.close(); return personList; } } ~~~ PersonEntity.java ~~~ package com.deppon.test05.entity; public class PersonEntity implements java.io.Serializable { private static final long serialVersionUID = -1138245964662330288L; private Integer id; private String name; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } @Override public String toString() { return "PersonEntity [id=" + id + ", name=" + name + "]"; } } ~~~ MyBatisUtil.java ~~~ package com.deppon.test05.util; import java.io.IOException; import java.io.InputStream; import org.apache.ibatis.io.Resources; import org.apache.ibatis.session.SqlSession; import org.apache.ibatis.session.SqlSessionFactory; import org.apache.ibatis.session.SqlSessionFactoryBuilder; public class MyBatisUtil { private static SqlSessionFactory factory = null; private static void initialFactory() { String resource = "mybatis-config.xml"; try { InputStream in = Resources.getResourceAsStream(resource); factory = new SqlSessionFactoryBuilder().build(in); } catch (IOException e) { e.printStackTrace(); } } public static SqlSession getSession() { if(factory == null) { initialFactory(); } return factory.openSession(); } } ~~~ 测试程序： ~~~ package com.deppon.test05.dao; import java.util.List; import org.junit.Before; import org.junit.Test; import com.deppon.test05.dao.impl.PersonEntityDao; import com.deppon.test05.entity.PersonEntity; public class PersonEntityDaoTest { private IPersonEntityDao personEntityDao; @Before public void before() { personEntityDao = new PersonEntityDao(); } @Test public void testQueryAll() { List<PersonEntity> personList = personEntityDao.queryAll(); for(PersonEntity each : personList) { System.out.println(each); } } @Test public void testInsert() { PersonEntity person = new PersonEntity(); person.setId(200); person.setName("乔巴"); personEntityDao.insert(person); } } ~~~ 项目结构如下图所示：  注意：记得那两条命令哦，亲 （前面的博客有） 结果:  --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- - [Maven学习（一）- 环境搭建](http://blog.csdn.net/jolingogo/article/details/8775046) - [Maven学习（二）- 安装m2eclipse插件 ](http://blog.csdn.net/jolingogo/article/details/8796410) - [Maven学习（三）- 使用Maven构建Web项目](http://blog.csdn.net/jolingogo/article/details/8796726) - [Maven学习（四）- 使用Maven构建Web项目-测试](http://blog.csdn.net/jolingogo/article/details/8797153) - [Maven学习（五）- 使用Maven构建Struts2项目](http://blog.csdn.net/jolingogo/article/details/8798052) - [Maven学习（六）- 构建Hibernate项目](http://blog.csdn.net/jolingogo/article/details/8798684) - [Maven学习（七）- 构建Spring项目](http://blog.csdn.net/jolingogo/article/details/8799307) - [Maven学习（八）- 构建MyBatis项目](http://blog.csdn.net/jolingogo/article/details/8801158) - [Maven学习（九）- 构建SSH项目](http://blog.csdn.net/jolingogo/article/details/8811817) - [Maven学习（十） - 阶段小结 ](http://blog.csdn.net/jolingogo/article/details/8821375) - [专栏：Maven学习之旅](http://blog.csdn.net/column/details/yuguiyang-maven.html)
