用mybatis  plus ，连oracle ，程序执行时报错：
原本SQL是：select xtwldm,xtwlmc from xtm14的不知怎么,字段名称都分离了，都带下划线了？
JDBC Connection [oracle.jdbc.driver.T4CConnection@2ea50632] will not be managed by Spring
==>  Preparing: SELECT x_t_w_l_d_m,x_t_w_l_m_c FROM xtm14
==> Parameters: 
Closing non transactional SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@5ebffb44]

org.springframework.jdbc.BadSqlGrammarException: 
### Error querying database.  Cause: java.sql.SQLSyntaxErrorException: ORA-00904: "X_T_W_L_M_C": 标识符无效

### The error may exist in com/erdos/dao/Xtm14Dao.java (best guess)
### The error may involve defaultParameterMap
### The error occurred while setting parameters
### SQL: SELECT  x_t_w_l_d_m,x_t_w_l_m_c  FROM xtm14
### Cause: java.sql.SQLSyntaxErrorException: ORA-00904: "X_T_W_L_M_C": 标识符无效

; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: ORA-00904: "X_T_W_L_M_C": 标识符无效

部分代码Xtm14Dao.java：
package com.xxxx.dao;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.xxxx.domain.xtm14;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;

import java.util.List;

@Mapper
public interface Xtm14Dao extends BaseMapper<xtm14> {
    @Select(" select XTWLDM,XTWLMC from xtm14 ")
    public List<xtm14> GetYhjList();

}

只需要在application.yml里面增加下面的即可：

mybatis-plus:
  configuration:
#    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
    map-underscore-to-camel-case: false
