mybatis-plus返回map自动转驼峰配置

（一）

mybatis-plus自带map下划线转驼峰配置类 

我们只需要在yml中配置一下object-wrapper-factory指定MybatisMapWrapperFactory就可以了

mybatis-plus:  mapper-locations: classpath:mapper/*Mapper.xml
   configuration:    call-setters-on-nulls: true
     map-underscore-to-camel-case: true
     object-wrapper-factory: com.baomidou.mybatisplus.extension.MybatisMapWrapperFactory

 @Component
    @ConfigurationPropertiesBinding
    public class ObjectWrapperFactoryConverter implements Converter<String,ObjectWrapperFactory> {
        @Override    
        public ObjectWrapperFactory convert(String source) {
            try {
                return (ObjectWrapperFactory) Class.forName(source).newInstance();
            } catch (InstantiationException | IllegalAccessException | ClassNotFoundException e) {
                throw new RuntimeException(e);
            }
        }
    }

@Bean
    public ConfigurationCustomizer mybatisConfigurationCustomizer(){
        return configuration -> configuration.setObjectWrapperFactory(new MybatisMapWrapperFactory());
    }
