今天写了个解析javax.persistence.Table的方法
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

找了一个晚上终于找到答案了。

原因是tomcat里面没有javaee-api-5.0-1.jar这个jar包，我用的是javaee 5.0。
