合併\ xEF \ xBF \ xBD

Question

異常我試圖合併一個對象，它有4個屬性（ID，FIRSTNAME，LASTNAME，SCORE），使用JPA作爲ORM和MySQL作爲RDBMS，我只更新特定ID的分數並獲得例外。

08:53:23,521 WARN [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (Thread-35) SQL Error: 1366, SQLState: HY000 
08:53:23,521 ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (Thread-35) Incorrect string value: '\xEF\xBF\xBD' for column 'FIRSTNAME' at row 1

我該如何擺脫這個問題？謝謝！

EDIT表排序規則是utf8_general_ci

Answer 1

0xEF 0xBF 0xBD是針對U + FFFD碼點的UTF-8編碼的形式。這發生在UTF-8解析器無法將字節序列解析爲有效的UTF-8序列時發生。

從你的錯誤，它看起來像Hibernate提供這個無效的序列。因此，您需要確定堆棧中的數據處理元素是否使用不正確的編碼解析數據。
