1、添加pom.xml,获取依赖的jar包

2.在src/main/resource 下面添加config.properties和generatorConfig.xml文件
config.properties 文件
mapper.plugin = tk.mybatis.mapper.generator.MapperPlugin
mapper.Mapper = tk.mybatis.mapper.common.Mapper
generatorConfig.xml 文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
<properties resource="config.properties" />
<classPathEntry location="C:\Users\lijing\.m2\repository\mysql\mysql-connector-java\5.1.36\mysql-connector-java-5.1.36.jar" />
<context id="MySqlTables" targetRuntime="MyBatis3">
<property name="beginningDelimiter" value="`" />
<property name="endingDelimiter" value="`" />
<plugin type="${mapper.plugin}">
<property name="mappers" value="${mapper.Mapper}" />
<property name="caseSensitive" value="true" />
</plugin>
<commentGenerator>
<property name="suppressAllComments" value="true" />
</commentGenerator>
<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://172.16.10.233:3306/test" userId="scal_store" password="123456">
</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>
<javaModelGenerator targetPackage="${targetModelPackage}" targetProject="${targetJavaProject}" />
<sqlMapGenerator targetPackage="${targetXMLPackage}" targetProject="${targetResourcesProject}" />
<javaClientGenerator targetPackage="${targetMapperPackage}" targetProject="${targetJavaProject}" type="XMLMAPPER" />
<table tableName="STUDENT" domainObjectName="Student" alias="student" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"
enableSelectByExample="false" selectByExampleQueryId="false">
</table>
</context>
</generatorConfiguration>
3 、写Student 类
package com.bw30.store.dao.model.pojo;
import javax.persistence.*;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@NoArgsConstructor
@Table(name="Student")
public class Student {
@Column(name="id")
private String id;
@Column(name="name")
private String name;
@Column(name="age")
private Integer age;
@Column(name="address")
private String address;
}
4、运行maven
点击项目右键，选择Run,然后选择maven build .. ,输入mybatis-generator:generate
可以生成StudentMapper.java和StudentMapper.xml
5、spring-dao.xml 书写
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc"

application-dao.properties文件
jdbc.driver=com.mysql.jdbc.Driver
jdbc.jdbcUrl=jdbc:mysql://172.16.10.233:3306/test?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull
jdbc.user=scal_store
jdbc.password=123456
jdbc.maxPoolSize=50
jdbc.minPoolSize=20
jdbc.initialPoolSize=1
jdbc.maxIdleTime=50
jdbc.checkoutTimeout=10000
jdbc.acquireRetryAttempts=3
jdbc.idleConnectionTestPeriod=50
jdbc.maxStatements=20
6、获取SqlSessionFactory
String resource = "applicationContext-dao.xml";
ClassPathXmlApplicationContext xmlApplicationContext = new ClassPathXmlApplicationContext(resource);
sqlSessionFactory = xmlApplicationContext.getBean("sqlSessionFactory", SqlSessionFactory.class);
SqlSession openSession = sqlSessionFactory.openSession();
StudentMapper mapper = openSession.getMapper(StudentMapper.class);
List<Student> selectByExample = mapper.selectByExample(new Example(Student.class));
System.out.println(selectByExample.size());
openSession.close();
