        Bug
        • spring

        Why is this an issue?

        Use of a Spring SingleConnectionFactory without enabling the reconnectOnException setting will prevent automatic connection recovery when the connection goes bad.

        That’s because the reconnectOnException property defaults to false. As a result, even if the code that uses this connection factory (Spring’s DefaultMessageListenerContainer or your own code) has reconnect logic, that code won’t work because the SingleConnectionFactory will act like a single-connection pool by preventing connection close calls from actually closing anything. As a result, subsequent factory create operations will just hand back the original broken Connection.

        Noncompliant code example

         <bean id="singleCF" class="org.springframework.jms.connection.SingleConnectionFactory">  <!-- Noncompliant -->
           <constructor-arg ref="dummyConnectionFactory" />
         </bean>
        

        Compliant solution

         <bean id="singleCF" class="org.springframework.jms.connection.SingleConnectionFactory" p:reconnectOnException="true">
           <constructor-arg ref="dummyConnectionFactory" />
         </bean>
        

        or

         <bean id="singleCF" class="org.springframework.jms.connection.SingleConnectionFactory">
           <constructor-arg ref="dummyConnectionFactory" />
           <property name="reconnectOnException"><value>true</value></property>
         </bean>
