MyBatis常用的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>
