MyBatis 存储字段类型

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>
