JBoss AS Web 7.0.2管道異常中斷會斷開應用程序和數據庫的連接

Question

我的服務器配置為：

• JBOSS AS WEB 7.0.2
• Java（版本“ 1.6.0_34” OpenJDK運行時環境（IcedTea6 1.13.6）（rhel-1.13.6.1.el6_6-x86_64）OpenJDK 64位服務器VM（內部版本23.25-b01，混合模式）

另外，我的應用程序位於HTTPS上 。

發生的是，我的日志文件中出現以下錯誤，並且我的應用程序正在運行，並且內存或CPU消耗不大，並且硬盤足夠，但是我的應用程序與數據庫的連接不存在（所有連接都消失了）。 因此，每當我打開使用DB的頁面時，都不會打開，並且頁面加載器正在加載和加載。

我檢查了我的代碼，並認為未關閉的OutputStream導致了此問題，所以我正確地關閉了所有組件。 但是這個問題仍然存在。

誰能幫助我理解並提供此問題的解決方案？

以下是我當前的數據源：

<bean id="myDataSource" class="com.jolbox.bonecp.BoneCPDataSource" destroy-method="close"> <property name="driverClass" value="com.mysql.jdbc.Driver" /> <property name="jdbcUrl" value="jdbc:mysql://${host}:${port} /${db_name}?autoReconnect=true" /> <property name="username" value="${user}" /> <property name="password" value="${password}" /> <property name="idleConnectionTestPeriodInSeconds" value="10" /> <property name="idleMaxAge" value="240" /> <property name="maxConnectionsPerPartition" value="30" /> <property name="minConnectionsPerPartition" value="10" /> <property name="partitionCount" value="3" /> <property name="acquireIncrement" value="5" /> <property name="acquireRetryAttempts" value="30" /> <property name="statementsCacheSize" value="100" /> <property name="releaseHelperThreads" value="3" /> <property name="connectionTestStatement" value="/* ping *\\/ SELECT 1" /> <property name="acquireRetryDelayInMs" value="10000" /> </bean>

這是由於另一端已經關閉連接時寫入該連接引起的。 數據庫連接已關閉數據庫連接，但對於您的應用程序，數據庫連接是打開的，因此當嘗試在數據庫連接上寫入時，會出現管道破裂錯誤

編輯添加我的數據源詳細信息，但不會出現此錯誤：

<Resource name="jdbc/MySQLDS"
              url="jdbc:mysql://${MYSQL_DB_HOST}:${MYSQL_DB_PORT}/${APP_NAME}"
              driverClassName="com.mysql.jdbc.Driver"
              username="${MYSQL_DB_USERNAME}"
              password="${MYSQL_DB_PASSWORD}"
              auth="Container"
