Как исправить "SchemaUpdate - HHH000319: не удалось получить метаданные базы данных", поскольку пакет для запроса слишком большой (5 526 600 > 65 535)
0 Я хочу подключить весеннюю загрузку к базе данных mysql на глобальном сервере, но обнаружил ошибку "HHH000319: не удалось получить метаданные базы данных", поскольку пакет для запроса слишком велик (5 526 600> 65 535). Вы можете изменить это значение на сервере, установив переменную max_allowed_packet. Но я заменил max_allowed_packet на большее, хотя значение переменной max_allowed_packet больше, чем значение отправленного пакета, но все равно я получаю ту же ошибку
Я заменил переменную max_allowed_packet в настройках переменной phpmyadmin в моей cpanel на max_allowed_packet = 999,999,999. Я также перезапустил свой сервер
pom.xml
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.16</version>
applicationContext.xml
<bean id="db" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.cj.jdbc.Driver" />
<property name="url" value="jdbc:mysql://103.65.0.0:2083/database" />
<property name="username" value="username" />
<property name="password" value="password" />
</bean>
Я ожидаю, что смогу соединиться с базами данных MySQL на глобальных серверах, но я получаю эту ошибку:
