hibernate配置oracle sequence主键相关异常

 

<id name="id" type="java.math.BigDecimal">

改为:

<id name="id" type="java.lang.Integer">

 <generator class="native"></generator>

改为

            <generator class="native">
             <param name="sequence">SEQUENCE_1000</param>
            </generator>

SEQUENCE_1000是ORACLE中库表所对应的序列

JAVA 的INTERGER对应ORACLE中的NUMBER最大长度是18
