Hibernate本机SQL

在执行以下本机sql hibernate应用程序时，我得到了java.sql.SQLException:无效的列名。 我正在使用Oracle11g。我还有一个包含以下列的Employee表

代码 这是映射文件

<!-- employee.hbm.xml -->




<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <class name="Employee" table="Employee">
        <id name="empNumber" column="EMPLOYEE_NUMBER "></id>
        <property name="empName"`enter code here` column="EMPLOYEE_NAME"></property>
        <property name="empSal" column="EMPLOYEE_SALARY"></property>
        <property name="deptNumber" column="DEPT_NUMBER"></property>
    </class>
</hibernate-mapping>

提出的例外情况

---

出现问题的原因是列名的最后一个字符有空格：

<id name="empNumber" column="EMPLOYEE_NUMBER "></id>

最有可能的列名是

EMPLOYEE\u NUMBER

，没有额外的空格
