<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >

<hibernate-reverse-engineering>

<table name="customerbases" catalog="erp" class="customerbases">
<primary-key>
<generator class="native"></generator>
<column name="CUST_ID" jdbc-type="varchar" property="cust_id" type="String"/>
</primary-key>
</table>
</hibernate-reverse-engineering>
这里的class="customerbases"写成类名试一下

<table name="customerbases" catalog="erp" class="customerbases">
<primary-key>
<generator class="native"></generator>
<column name="CUST_ID" jdbc-type="varchar" property="cust_id" type="String"/>
</primary-key>
</table>
</hibernate-reverse-engineering>

请去掉红色部分代码， class里的类必须包括包全路径。
