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：
@Mod(modid = MyMod.MODID, name = MyMod.NAME, version = MyMod.VERSION), acceptableRemoteVersions = "*"
public class MyMod {
....
}
我已尝试解决问题，如SO中的另一个问题所示，但它对我不起作用。
以下是我在配置文件中所做的事情：

请注意，如果我刷新页面，一切正常。有人知道要解决这个问题吗？

块，现在应用程序启动了。我需要检查几小时后是否发生错误。
properties答案 0 :(得分：1)
因此，我认为dbCreate，url，username和password以外的所有内容都必须位于属性块中：
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
}
}
答案 1 :(得分：1)
虽然这应该很奇怪但是如果Grails应用程序和MySQL服务器都在同一台机器上，那么使用localhost或127.0.0.代替真实IP地址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
}
答案 2 :(得分：0)
请尝试下面的操作，而不是添加driverClassName和dialect，我还添加了pooled以备不时之需
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
}
}
答案 3 :(得分：-2)
在我看来，MySQL正在超时它与你的连接。可能你做的不多。
如果连接暂时没有流量，可以考虑关闭连接，然后在需要时重新打开它吗？
