Spring應用程序沒有響應

我有連接到MySQL數據庫的Spring MVC應用程序。它運行在Tomcat服務器上。我有一個問題，即應用程序在幾個請求後沒有響應。Spring應用程序沒有響應

案例：我重新啓動Tomcat服務器並在瀏覽器中打開一個頁面。應用程序運行並且服務器將生成的頁面返回給瀏覽器。但是，當我在瀏覽器中打開第5-6頁時，服務器不響應。瀏覽器仍在加載沒有迴應。

這裏是從Tomcat構造的連接器的server.xml

<Connector SSLEnabled="true" acceptCount="100" clientAuth="false" disableUploadTimeout="true" enableLookups="false" keystoreFile="C:\Users\misco\.keystore" keystorePass="changeit" maxThreads="200" minSpareThreads="25" maxSpareThreads="75" connectionTimeout="20000" port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" scheme="https" secure="true" sslProtocol="TLS"/>

我試圖監視使用jvisualvm工具Tomcat的。

我也看了一下MySQL服務器的狀態。有線程有睡眠狀態。

這是線程轉儲的一部分，從jvisualvm。

你能給我一個建議如何解決這個問題？

編輯1：

下面是DB連接

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" 
     destroy-method="close" p:driverClassName="${jdbc.driverClassName}" 
     p:url="${jdbc.databaseurl}" p:username="${jdbc.username}" p:password="${jdbc.password}" /> 

    <!-- Hibernate --> 
    <bean id="sessionFactory" 
     class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
     <property name="dataSource" ref="dataSource" /> 
     <property name="configLocation"> 
      <value>classpath:hibernate.cfg.xml</value> 
     </property> 
     <property name="configurationClass"> 
      <value>org.hibernate.cfg.AnnotationConfiguration</value> 
     </property> 
     <property name="hibernateProperties"> 
      <props> 
       <prop key="hibernate.dialect">${jdbc.dialect}</prop> 
       <prop key="hibernate.show_sql">true</prop> 
      </props> 
     </property> 
    </bean> 

    <bean id="transactionManager" 
     class="org.springframework.orm.hibernate3.HibernateTransactionManager"> 
     <property name="sessionFactory" ref="sessionFactory" /> 
     <property name="dataSource" ref="dataSource" /> 
    </bean>

數據庫連接相關的Spring bean未關閉。

看起來線程正在等待來自DBCP的連接。您可能忘記了在finally塊中關閉JDBC連接。 –

connectionTimeout =「20000」嘗試增加此值 –

@JBNizet我使用hibernate進行連接管理，所以我沒有使用任何finally塊。 – misco

看來你可能不會在com.myapp.cloud.dao.store.ProductDAOImpl.get(ProductDAOImpl.java關閉休眠會話。來自池的連接全部由前5個請求使用，並且後續請求正在等待來自數據庫連接池的新連接。

Spring應用程序沒有響應
