1.MyBatis通过包含的jdbcType类型

BIT         FLOAT      CHAR           TIMESTAMP       OTHER       UNDEFINED
TINYINT     REAL       VARCHAR        BINARY          BLOB        NVARCHAR

SMALLINT    DOUBLE     LONGVARCHAR    VARBINARY       CLOB        NCHAR

INTEGER     NUMERIC    DATE           LONGVARBINARY   BOOLEAN     NCLOB

BIGINT      DECIMAL    TIME           NULL            CURSOR

2.Mybatis中javaType和jdbcType对应关系
