配置

在属性配置文件中配置数据库连接池信息

#jdbc配置
spring.datasource.druid.url=jdbc:mysql://localhost:3306/mybatis?useUnicode=true&characterEncoding=utf-8
spring.datasource.druid.username=root
spring.datasource.druid.password=root
spring.datasource.druid.driver-class-name=com.mysql.jdbc.Driver
#配置别名
mybatis.type-aliases-package=com.wendao.demo.pojo
#连接池配置
spring.datasource.druid.initial-size=20
spring.datasource.druid.max-active=400
spring.datasource.druid.min-idle=11
spring.datasource.druid.max-wait=1

自己管理SqlSessionFactory

package com.wendao.demo.conf;
import com.github.pagehelper.PageHelper;
import tk.mybatis.spring.mapper.MapperScannerConfigurer;
import org.apache.ibatis.plugin.Interceptor;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.condition.ConditionalOnBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import javax.sql.DataSource;
import java.util.Properties;
/*** 自己实例化sqlSessionFactory* 该sqlSessionFactory* 1：使用了druid数据库连接词* 2：添加了pagehelper分页插件*/
@Configuration
public class MyBatisConfig {@Autowiredprivate DataSource dataSource;@Bean(name = "sqlSessionFactory")public SqlSessionFactory sqlSessionFactoryBean()  {SqlSessionFactoryBean bean = new SqlSessionFactoryBean();bean.setDataSource(dataSource);bean.setTypeAliasesPackage("com.wendao.demo.pojo");//分页插件PageHelper pageHelper = new PageHelper();Properties properties = new Properties();properties.setProperty("reasonable", "true");properties.setProperty("supportMethodsArguments", "true");properties.setProperty("returnPageInfo", "check");properties.setProperty("params", "count=countSql");pageHelper.setProperties(properties);//添加插件bean.setPlugins(new Interceptor[]{pageHelper});try {//bean.setMapperLocations(resolver.getResources("classpath:mapper/*.xml"));return bean.getObject();} catch (Exception e) {e.printStackTrace();throw new RuntimeException(e);}}@Beanpublic PlatformTransactionManager annotationDrivenTransactionManager() {return new DataSourceTransactionManager(dataSource);}
}

手动管理包扫描器

package com.wendao.demo.conf;
import org.springframework.boot.autoconfigure.AutoConfigureAfter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import tk.mybatis.spring.mapper.MapperScannerConfigurer;
@Configuration
//必须在MyBatisConfig注册后再加载MapperScannerConfigurer，否则会报错
@AutoConfigureAfter(MyBatisConfig.class)
public class MyBatisMapperScannerConfig {@Beanpublic MapperScannerConfigurer mapperScannerConfigurer() {MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory");mapperScannerConfigurer.setBasePackage("com.wendao");return mapperScannerConfigurer;}
}
