Исключенное прерывание трубы с MySql в приложении Grails

Question

Я развернул приложение Grails 2.2.1 на удаленный сервер. Через несколько часов, когда я получить доступ к домашней странице приложения, я вижу следующее исключение:

Error 500: Internal Server Error

You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

Я попытался решить эту проблему, как видно на другой вопрос в SO, но он не работает меня.

Вот что я сделал в конфигурационном файле:

dataSource { 
     dbCreate = "update" 
     url = "jdbc:mysql://urlofapp/myappname?useUnicode=yes&characterEncoding=UTF-8" 
     username = "root" 
     password = "root" 
     //run the evictor every 30 minutes and evict any connections older than 30 minutes. 
     minEvictableIdleTimeMillis=1800000 
     timeBetweenEvictionRunsMillis=1800000 
     numTestsPerEvictionRun=3 
     //test the connection while its idle, before borrow and return it 
     testOnBorrow=true 
     testWhileIdle=true 
     testOnReturn=true 
     validationQuery="SELECT 1" 
    } 

Обратите внимание, что, если я обновить страницу, все работает правильно. Кто-нибудь знает что-то, чтобы решить эту проблему?

EDIT 1:

Я редактировал my.cnf файл в /etc папку, добавив следующее:

wait_timeout = 28800 
interactive_timeout = 28800 

, но ничего не меняется

EDIT 2:

Это фактические данные sourc е, что я использую. Сломанная труба все еще появляется

dataSource { 
    dbCreate = "update" 
    url = "jdbc:mysql://urlofapp/myappname?useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true" 
    username = "root" 
    password = "root" 
    minIdle = 5 
    maxIdle = 25 
    maxWait = 10000 
    maxAge = 10 * 60000 
    timeBetweenEvictionRunsMillis = 5000 
    minEvictableIdleTimeMillis = 60000 
    validationQuery = "SELECT 1" 
    validationQueryTimeout = 3 
    validationInterval = 15000 
    testOnBorrow = true 
    testWhileIdle = true 
    testOnReturn = false 
    jdbcInterceptors = "ConnectionState;StatementCache(max=200)" 
    defaultTransactionIsolation = java.sql.Connection.TRANSACTION_READ_COMMITTED 
}

EDIT 4:

Я отредактировал блок properties, и теперь приложение запускается. Мне нужно проверить, возникает ли ошибка через несколько часов.

properties{ 
       minIdle = 5 
       maxIdle = 25 
       maxWait = 10000 

       timeBetweenEvictionRunsMillis = 5000 
       minEvictableIdleTimeMillis = 60000 
       validationQuery = "SELECT 1" 
       validationQueryTimeout = 3 

       testOnBorrow = true 
       testWhileIdle = true 
       testOnReturn = false 

       defaultTransactionIsolation = java.sql.Connection.TRANSACTION_READ_COMMITTED 
     } 

Answer 1

кажется мне, как MySQL является таймаут это подключение к вы. Наверное, вы не можете это сделать.

Можете ли вы рассмотреть возможность закрытия соединения, если на нем нет трафика, а затем снова открыть его, когда он понадобится снова?

Answer 2

Так что я считаю, все, кроме dbCreate, url, username и password потребности быть в свойствах блока:

dataSource { 
    dbCreate = "update" 
    url = "jdbc:mysql://urlofapp/myappname?useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true" 
    username = "root" 
    password = "root" 
    properties { 
     minIdle = 5 
     maxIdle = 25 
     maxWait = 10000 
     maxAge = 10 * 60000 
     timeBetweenEvictionRunsMillis = 5000 
     minEvictableIdleTimeMillis = 60000 
     validationQuery = "SELECT 1" 
     validationQueryTimeout = 3 
     validationInterval = 15000 
     testOnBorrow = true 
     testWhileIdle = true 
     testOnReturn = false 
     jdbcInterceptors = "ConnectionState;StatementCache(max=200)" 
     defaultTransactionIsolation = java.sql.Connection.TRANSACTION_READ_COMMITTED 
    } 
} 

Answer 3

Хотя, это должно быть странно, но если приложение Grails и сервер MySQL оба на той же машине, а затем использовать localhost или 127.0.0. вместо реального IP-адреса xxx.xxx.xxx.xxx

dataSource { 
    dbCreate = "update" 
    url = "jdbc:mysql://localhost:3306/docgem_test_db?useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true" 
    // Your other properties 
} 

Answer 4

Пожалуйста, попробуйте ниже не добавление driverClassName и dialect, и я также добавил pooled в случае, если вам нужно что

dataSource { 
    pooled = true 
    driverClassName = "com.mysql.jdbc.Driver" 
    dialect = "org.hibernate.dialect.MySQL5InnoDBDialect" 
    dbCreate = "update" 
    url = "jdbc:mysql://urlofapp/myappname? useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true" 
    username = "root" 
    password = "root" 
    properties { 
     minIdle = 5 
     maxIdle = 25 
     maxWait = 10000 
     maxAge = 10 * 60000 
     timeBetweenEvictionRunsMillis = 5000 
     minEvictableIdleTimeMillis = 60000 
     validationQuery = "SELECT 1" 
     validationQueryTimeout = 3 
     validationInterval = 15000 
     testOnBorrow = true 
     testWhileIdle = true 
     testOnReturn = false 
     jdbcInterceptors = "ConnectionState;StatementCache(max=200)" 
     defaultTransactionIsolation = java.sql.Connection.TRANSACTION_READ_COMMITTED 
} 

}
