org.hibernate.type.NullableType nullSafeGet无法从结果集中读取列值：Numeric Overflow

Question

Hibernate:
   <id name="A" column="A" type="integer"></id>  
  <property name="B" column="B" type="integer"/>
  <property name ="ID" column="ID" type="string"/>
  <property name="REASON" column="REASON" type="string"/>
  <property name="TEST" column="TEST" type="string"/>
  <property name="C" column="C" type="string"/>
  <property name="UNIT" column="UNIT" type="string"/>   
  <property name="NO" column="NO" type="integer"/>      
  <property name="LIMIT" column="LIMIT" type="string"/>
  <property name="MAX_LIMIT" column="LIMIT" type="string"/>
  <property name="MEASURED_VALUE" column="MEASURED_VALUE" type="string"/>
  <property name="TEST_POINT" column="TEST_POINT" type="string"/>
  <property name="CD" column="CD" type="string"/>
  <property name="AID" column="AID" type="string"/>
  <property name="MID" column="MID" type="string"/>
  <property name="LAST_UPDATE_DT" column="LAST_UPDATE_DT"  /> 

爪哇：

private String ID;
private String MAX_LIMIT;
private String LIMIT;
private Date CREATE_DT;
private Integer A;
private Integer B;
private String C;
private Date LAST_UPDATE_DT;
private String MEASURED_VALUE;
private String MID;
private String ID;
private String REASON;
private String CD;
private Integer NO;
private String TEST;
private String UNIT;
private String TEST_POINT;
