您发布的代码不太可能会引发该异常，但是我尝试在假设太多细节的情况下进行回答以正确执行此操作。反正...

我认为：

1. 您正在使用JPA
2. 您设置了delimited-identifiers
3. 您还使用EclipseLink作为实现。

如果是，请执行以下操作：

在persistence.xml中包含目标数据库条目：

    <property name="eclipselink.target-database" value="org.eclipse.persistence.platform.database.AccessPlatformDelimiterConfig"/>

将新类添加到您的类路径中：

package org.eclipse.persistence.platform.database;

public class AccessPlatformDelimiterConfig extends AccessPlatform {

    private static final long serialVersionUID = 7034590043310425678L;

    public AccessPlatformDelimiterConfig() {
        super();
        this.tableQualifier = "";
        this.startDelimiter = "";
        this.endDelimiter = "";
    }
}
