异常：identifier of an instance of cn.ebank.pojo.News was altered from 2 to 2;

 原因：

 <id name="id" type="java.lang.Integer">
            <column name="ID" precision="22" scale="0" />
            <generator class="sequence">
             <param name="sequence">NEWS_ID_SEQ</param>
            </generator>
        </id>

把红色部分变成

 <id name="id" type="java.lang.Long">
            <column name="ID" precision="22" scale="0" />
            <generator class="sequence">
             <param name="sequence">NEWS_ID_SEQ</param>
            </generator>
        </id>、

把dao和service里对应的Integer改成Long
