hbm文件是用工具生成的:<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-lazy="false">
  <class name="PerformanceDal.Vo.T_JCSJ_JGKZ,PerformanceDal" table="T_JCSJ_JGKZ">
    <id name="C_JGID" column="C_JGID" type="String"  length="32"  unsaved-value="0">
      <generator class="assigned" />
    </id>
    <property name="C_SFKH" column="C_SFKH" type="String"  length="1"  />
    <property name="C_BMLX" column="C_BMLX" type="String"  length="1"  />
    <property name="C_JGJC" column="C_JGJC" type="String"  length="32"  />
    <property name="C_BMLD" column="C_BMLD" type="String"  length="32"  />
    <property name="C_ZGYLDID" column="C_ZGYLDID" type="String"  length="32"  />
