springboot mybatis plus 关闭驼峰式命名转换为下划线

报错信息是这样的：

org.springframework.jdbc.BadSqlGrammarException: 
### Error querying database.  Cause: java.sql.SQLSyntaxErrorException: Unknown column 'f_factory_manager_i_d' in 'field list'
### The error may exist in com/neu/edu/cloudfactoryplus/dao/FactoryMapper.java (best guess)
### The error may involve defaultParameterMap
### The error occurred while setting parameters
### SQL: SELECT  f_id AS f_id,f_factory_manager_i_d AS f_factoryManagerID,f_factory_name AS f_factoryName,f_factory_description AS f_factoryDescription,f_state AS f_state,version,deleted,gmt_create AS gmt_create,gmt_modified AS gmt_modified  FROM factory  WHERE  deleted=0
### Cause: java.sql.SQLSyntaxErrorException: Unknown column 'f_factory_manager_i_d' in 'field list'
; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: Unknown column 'f_factory_manager_i_d' in 'field list'

本来所有的Mybatis-Plus都写好了，但是一运行，发现自动生成的SQl语句中的查询列名和自己的有很大错误，自己仔细一看，原来是Mybatis-Plus自动的把我们的驼峰命名法转化为了下划线，这样的话就需要我们自己关一下（全自动有时候也不太好。。。）

在我们的配置文件中，加上这样的一句话：

mybatis-plus.configuration.map-underscore-to-camel-case=false

再运行一次就OK了！！！
