I need to execute some code from the Controller in different threads.
My structure:
@Controller MyController //invoked from frontend @RequestMapping MyMethod Loop future = asyncTaskExecutor.Submit(callable) End loop Get future results End MyMethod I am using AsyncTaskExecutor like in this example:
Any good Spring threading with a TaskExecutor examples?
public SendEmailController() {} public SendEmailController(AsyncTaskExecutor asyncTaskExecutor) { super(); this.asyncTaskExecutor = asyncTaskExecutor; } applicationContext.xml:
<bean id="sendEmailController" class="com.ts.bpu.email.web.SendEmailController"> <constructor-arg ref="asyncTaskExecutor" /> </bean> <bean id="asyncTaskExecutor" class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor"> <property name="corePoolSize" value="5" /> <property name="maxPoolSize" value="10" /> <property name="queueCapacity" value="25" /> </bean> But the constructor with the parameter never is used. But if I use only the constructor with parameter the exception trace is:
