今天寫了個解析javax.persistence.Table的方法
Java代碼:
- /**
- * 通過實體的anno獲得Mapping的數據庫表名
- * @param clazz 實體類
- * @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.");
- }
- }
在啟動tomcat的時候報錯

找了一個晚上終于找到答案了。

原因是tomcat里面沒有javaee-api-5.0-1.jar這個jar包，我用的是javaee 5.0。
