1、添加依赖
<dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.1.6</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.22</version></dependency><!--mybatisplus融合--><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.1.0</version><exclusions><exclusion><groupId>org.springframework.boot</groupId><artifactId>spring-boot-autoconfigure</artifactId></exclusion><exclusion><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-jdbc</artifactId></exclusion></exclusions></dependency>
2、添加代码开发
package com.goldcard.lifecycle.dao.config;import com.alibaba.druid.pool.DruidDataSource; import com.baomidou.mybatisplus.extension.spring.MybatisSqlSessionFactoryBean; import lombok.extern.slf4j.Slf4j; import org.apache.ibatis.session.SqlSessionFactory; import org.mybatis.spring.SqlSessionTemplate; import org.mybatis.spring.annotation.MapperScan; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.beans.factory.annotation.Value; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.Primary; import org.springframework.core.io.support.PathMatchingResourcePatternResolver;import javax.sql.DataSource;/*** db数据源配置** @author xiaozhilei*/@Configuration @MapperScan(basePackages = "com.dao.mapper", sqlSessionFactoryRef = "dbSqlSessionFactory") @Slf4j public class DataSourceConfig {@Value("${spring.datasource.db.url}")private String dbUrl;@Value("${spring.datasource.db.password}")private String password;@Value("${spring.datasource.db.username}")private String username;/*** 包名*/private static final String TypeAliasesPackage = "com.dao.domain";/*** mapper扫面包路径*/private static final String MapperLocations = "classpath*:mapper/*.xml";@Primary@Bean("dbDataSource")@ConfigurationProperties(prefix = "spring.datasource.db")public DataSource getDbDataSource() {log.info("数据库环境配置地址.{}",dbUrl);log.info("数据库环境配置用户名.{}",username);log.info("数据库环境配置密码.{}",password);return new DruidDataSource();//return DataSourceBuilder.create().build(); }@Primary@Bean("dbSqlSessionFactory")public SqlSessionFactory dbSqlSessionFactory(@Qualifier("dbDataSource") DataSource dataSource) throws Exception {//SqlSessionFactoryBean bean = new SqlSessionFactoryBean();MybatisSqlSessionFactoryBean bean = new MybatisSqlSessionFactoryBean();bean.setDataSource(dataSource);bean.setTypeAliasesPackage(TypeAliasesPackage);bean.setConfigLocation(new PathMatchingResourcePatternResolver().getResource("classpath:/config/mybatis-config.xml"));bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources(MapperLocations));return bean.getObject();}@Primary@Bean("dbSqlSessionTemplate")public SqlSessionTemplate dbSqlSessionTemplate(@Qualifier("dbSqlSessionFactory") SqlSessionFactory sqlSessionFactory) {return new SqlSessionTemplate(sqlSessionFactory);} }
3 添加相关依赖
在：resources目录下，创建：mybatis-config.xml
然后添加如下代码：配置mybatis的驼峰命名等
<?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><settings><setting name="mapUnderscoreToCamelCase" value="true" /></settings> </configuration>
