mybatis常用jdbcType数据类型

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

 

Mybatis中javaType和jdbcType对应和CRUD例子

<resultMap type="java.util.Map" id="resultjcm">
  <result property="FLD_NUMBER" column="FLD_NUMBER"  javaType="double" jdbcType="NUMERIC"/>
  <result property="FLD_VARCHAR" column="FLD_VARCHAR" javaType="string" jdbcType="VARCHAR"/>
  <result property="FLD_DATE" column="FLD_DATE" javaType="java.sql.Date" jdbcType="DATE"/>
  <result property="FLD_INTEGER" column="FLD_INTEGER"  javaType="int" jdbcType="INTEGER"/>
  <result property="FLD_DOUBLE" column="FLD_DOUBLE"  javaType="double" jdbcType="DOUBLE"/>
  <result property="FLD_LONG" column="FLD_LONG"  javaType="long" jdbcType="INTEGER"/>
  <result property="FLD_CHAR" column="FLD_CHAR"  javaType="string" jdbcType="CHAR"/>
  <result property="FLD_BLOB" column="FLD_BLOB"  javaType="[B" jdbcType="BLOB" />
  <result property="FLD_CLOB" column="FLD_CLOB"  javaType="string" jdbcType="CLOB"/>
  <result property="FLD_FLOAT" column="FLD_FLOAT"  javaType="float" jdbcType="FLOAT"/>
  <result property="FLD_TIMESTAMP" column="FLD_TIMESTAMP"  javaType="java.sql.Timestamp" jdbcType="TIMESTAMP"/>
 </resultMap>
