mysql - Grails 应用程序中 MySql 的管道异常

Question

我已将 Grails 2.2.1 应用程序部署到远程服务器。几个小时后，当我访问应用程序的主页时，我看到以下异常:

Error 500: Internal Server Error

    /DocGemStudioZoccali/

我已经尝试解决在 SO 中的另一个问题中看到的问题，但它对我不起作用。

这是我在配置文件中所做的:

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"
    }

请注意，如果我刷新页面，一切正常。有人知道解决这个问题的方法吗？

编辑 1:

我编辑了 /etc 文件夹中的 my.cnf 文件，添加了以下内容:

wait_timeout = 28800
interactive_timeout = 28800

但没有任何变化

这是我正在使用的实际数据源。断管依旧出现

dataSource {
   dbCreate = "update"
   url = "jdbc:mysql://urlofapp/myappname?useUnicode=yes&characterEncoding=UTF-8&autoReconnect=true"
   username = "root"

我已经编辑了 properties block ，现在应用程序启动了。我需要检查几个小时后是否发生错误。

 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

所以我相信除了 dbCreate、url、username 和 password 之外的所有内容都需要在属性 block :

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
    }
}
