一：jar包下载：
https://github.com/mybatis/mybatis-3/releases?after=mybatis-3.2.8
我使用的版本是3.2,7
二、创建项目 导入核心jar包和依赖的jar包。
pom.xml文件内容：
1 <properties> 2 <!--需要注意还珠格格编译器的版本要和jdk版本一直--> 3 <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 4 <maven.compiler.source>1.8</maven.compiler.source> 5 <maven.compiler.target>1.8</maven.compiler.target> 6 </properties> 7 8 <dependencies> 9 <dependency> 10 <groupId>org.slf4j</groupId> 11 <artifactId>slf4j-log4j12</artifactId> 12 <version>1.7.5</version> 13 </dependency> 14 <dependency> 15 <groupId>org.slf4j</groupId> 16 <artifactId>slf4j-api</artifactId> 17 <version>1.7.5</version> 18 </dependency> 19 <dependency> 20 <groupId>org.apache.logging.log4j</groupId> 21 <artifactId>log4j-core</artifactId> 22 <version>2.0.2</version> 23 </dependency> 24 <dependency> 25 <groupId>org.apache.logging.log4j</groupId> 26 <artifactId>log4j-api</artifactId> 27 <version>2.0.2</version> 28 </dependency> 29 <dependency> 30 <groupId>mysql</groupId> 31 <artifactId>mysql-connector-java</artifactId> 32 <version>5.1.34</version> 33 </dependency> 34 <dependency> 35 <groupId>log4j</groupId> 36 <artifactId>log4j</artifactId> 37 <version>1.2.17</version> 38 </dependency> 39 <dependency> 40 <groupId>org.javassist</groupId> 41 <artifactId>javassist</artifactId> 42 <version>3.16.1-GA</version> 43 </dependency> 44 <dependency> 45 <groupId>commons-logging</groupId> 46 <artifactId>commons-logging</artifactId> 47 <version>1.1.1</version> 48 </dependency> 49 <dependency> 50 <groupId>cglib</groupId> 51 <artifactId>cglib</artifactId> 52 <version>2.2.2</version> 53 </dependency> 54 <dependency> 55 <groupId>asm</groupId> 56 <artifactId>asm</artifactId> 57 <version>3.3.1</version> 58 </dependency> 59 <dependency> 60 <groupId>org.mybatis</groupId> 61 <artifactId>mybatis</artifactId> 62 <version>3.2.7</version> 63 </dependency> 64 <dependency> 65 <groupId>junit</groupId> 66 <artifactId>junit</artifactId> 67 <version>4.11</version> 68 <scope>test</scope> 69 </dependency> 70 <dependency> 71 <groupId>org.junit.jupiter</groupId> 72 <artifactId>junit-jupiter-api</artifactId> 73 <version>RELEASE</version> 74 </dependency> 75 </dependencies>
