SpringBoot开启驼峰映射

一 、application.yml配置

        mybatis:  

            configuration:     

                    map-underscore-to-camel-case: true

二、光这样配置你会发现mapper的驼峰映射并未起作用，需要在DataSource配置类添加下方划线标志的代码

@Bean(name="config")

@ConfigurationProperties(prefix = "mybatis.configuration")

public org.apache.ibatis.session.Configuration mybatiesConfig(){ 

   return new org.apache.ibatis.session.Configuration();}

@Bean(name = "campaignsSqlSessionFactory")

public SqlSessionFactory campaignsSqlSessionFactory(

@Qualifier( "campaignsDataSource") DataSource campaignsDataSource,

org.apache.ibatis.session.Configuration config) throws Exception {

final SqlSessionFactoryBean sqlSessionFactoryBean =

new SqlSessionFactoryBean();

sqlSessionFactoryBean.setDataSource(campaignsDataSource);

Resource[] mapperLocations = new

PathMatchingResourcePatternResolver().getResources(CampaignsConfig. MAPPER_LOCATION); sqlSessionFactoryBean.setMapperLocations(mapperLocations);

sqlSessionFactoryBean.setTypeAliasesPackage( TYPE_ALIASES_PACKAGE);

sqlSessionFactoryBean.setConfiguration(config);

return sqlSessionFactoryBean.getObject();}

三、或者在mapper.xml文件中使用resultMap也可实现手动设置的映射

<resultMap type="com.nttdata.dm30.club.admin.model.entity.bbs.YJHAutoRewardLog" id="youjuhuilogMap">
    <result property="logId" column="log_id"/>
    <result property="logDetail" column="log_detail"/>
    <result property="logTime" column="log_time"/>
    <result property="logStatus" column="log_status"/>
resultMap>
