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>
