Springboot整合mybatis配置下劃線轉駝峯

1、通過application.properties配置文件

mybatis.configuration.mapUnderscoreToCamelCase=true
mybatis.configuration.map-underscore-to-camel-case=true
#以上兩種方式根據自己IDE版本選擇其中一種進行配置即可

2、通過@configuration註解配置的方式

@Bean(name = "sqlSessionFactory")
public SqlSessionFactory sqlSessionFactoryBean() throws IOException {
    SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
    bean.setDataSource(dataSource);
    PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
    bean.setMapperLocations(resolver.getResources("classpath:/mapper//.xml"));
    try {
        //開啓駝峯命名轉換
        bean.getObject().getConfiguration().setMapUnderscoreToCamelCase(true);
        return bean.getObject();
    } catch (Exception e) {
        e.printStackTrace();
        throw new RuntimeException(e);
    }
}

以上兩種方式均可實現下劃線轉駝峯的功能，具體怎麼選擇看個人喜好！
