ngoại lệ ống bị hỏng với MySql trong ứng dụng Grails

Question

Tôi đã triển khai ứng dụng Grails 2.2.1 vào máy chủ từ xa. Sau một vài giờ, khi tôi truy cập vào trang chủ của ứng dụng, tôi thấy ngoại lệ sau:

Error 500: Internal Server Error

    /DocGemStudioZoccali/

Tôi đã cố giải quyết vấn đề như đã thấy trong câu hỏi khác trong SO, nhưng nó không hoạt động cho tôi.

Dưới đây là những gì tôi đã thực hiện bên trong tập tin cấu hình:

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" 
    } 

Chú ý rằng, nếu tôi làm mới trang, mọi thứ hoạt động một cách chính xác. Có ai biết gì để giải quyết vấn đề này không?

EDIT 1:

tôi đã chỉnh sửa các tập tin my.cnf trong /etc thư mục, thêm những điều sau đây:

wait_timeout = 28800 
interactive_timeout = 28800 

nhưng có gì thay đổi

EDIT 2:

Đây là dữ liệu thực tế sourc e tôi đang sử dụng. đường ống bị hỏng vẫn xuất hiện

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 
}

Đây là stacktrace sau khi đề nghị được đưa ra bởi James Kleeh

EDIT 4:

Tôi đã chỉnh sửa khối properties và bây giờ ứng dụng bắt đầu. Tôi cần kiểm tra xem lỗi có xảy ra sau vài giờ không.

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

Trông với tôi như MySQL là thời điểm ra nó kết nối đến bạn. Có lẽ không nhiều bạn có thể làm về điều đó.

Bạn có thể xem xét đóng kết nối nếu không có lưu lượng truy cập trên đó trong một thời gian và sau đó mở lại khi cần thiết một lần nữa không?

Answer 2

Vì vậy, tôi tin rằng tất cả mọi thứ khác hơn dbCreate, url, username, và password nhu cầu để được trong một thuộc tính chặn:

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

Mặc dù, điều này sẽ là kỳ lạ nhưng nếu ứng dụng Grails và máy chủ MySQL cả hai đều trên cùng một máy sau đó sử dụng localhost hay 127.0.0. thay vì địa chỉ IP thực 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

Vui lòng thử dưới đây không việc bổ sung các driverClassName và dialect và tôi cũng nói thêm pooled trong trường hợp bạn cần điều đó

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 
} 

}
