mybatis mapper.xml数据库映射生成java实体，增删改查sql语句

1.问题描述：使用mybatis生成mapper.xml文件的时候经常遇到数据库表字段很多，写mapper.xml文件时转化成java实体很麻烦，写增删改查的sql时也要做

很多重复的工作。程序员就想一劳永逸，我拼接了几个sql可以简化，方便生成数据库映射和java实体。（待解决问题，没有JDBCTYPE，需要再建立一个映射java类型和数据库字段类型的关系表）

2.解决：

先来一个表结构（字段很多，要是一个一个写，早烦啦烦啦，死啦死啦，怎么破？）

 2.1 mysql版本(后面有oracle版本）

先建立一个拼sql的函数（做了两件事,把下划线后面的字母大写，去除下划线）

CREATE 
FUNCTION fun_yxl_rep(str varchar(128))
  RETURNS varchar(128) CHARSET utf8
BEGIN
  DECLARE len,
          i int;
  DECLARE ch char;
  DECLARE s1,s2 varchar(128);
  SET i = 1;
  SELECT
    LENGTH(str) INTO len;
  WHILE (i <= len) DO
    SET ch = SUBSTRING(str, i, 1);
    IF (ch = '_' and (i+1) <= len) THEN
      set s1 = SUBSTRING(str, 1, i);
      set s2 = SUBSTRING(str, i+2, len - i);
      SET str = CONCAT(s1,UPPER(SUBSTRING(str, i+1, 1)),s2);
    END IF;
    SET i = i + 1;
  END WHILE;
  RETURN REPLACE(str,'_','');
END

2.2使用

2.2.1.生成表的列升序排列（注意修改表名和schema就可以用了）

select CONCAT('t.',COLUMN_NAME,',') from information_schema.COLUMNS where 
table_name = 't_ltl_order' and table_schema = 'oms'order by COLUMN_NAME;

结果：

t.accepter,
t.accepter_mobile,
t.accepter_name,
t.accept_deptid,
