Java代码:

/**

* 通过实体的anno获得Mapping的 数据库表名

* @param clazz 实体类

* @return

* @throws Exception

*/

public static String getTableName(Class< > clazz) throws Exception {

if (clazz.isAnnotationPresent(Table.class)) {

Table table = clazz.getAnnotation(Table.class);

return table.name();

} else {

throw new Exception(clazz.getName() + " is not Entity Annotation.");

}

}

在启动tomcat的时候报错
