【Mybatis】 JdbcType 与 JavaType对应关系

一、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

二、XML

<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>
