Certain global framework properties can be overridden by providing a properties file on the classpath.spring-doc.cn

The default properties can be found in org.springframework.integration.context.IntegrationProperties class. The following listing shows the default values:spring-doc.cn

spring.integration.channels.autoCreate=true (1)
spring.integration.channels.maxUnicastSubscribers=0x7fffffff (2)
spring.integration.channels.maxBroadcastSubscribers=0x7fffffff (3)
spring.integration.taskScheduler.poolSize=10 (4)
spring.integration.messagingTemplate.throwExceptionOnLateReply=false (5)
spring.integration.readOnly.headers= (6)
spring.integration.endpoints.noAutoStartup= (7)
spring.integration.channels.error.requireSubscribers=true (8)
spring.integration.channels.error.ignoreFailures=true (9)
spring.integration.endpoints.defaultTimeout=30000 (10)
1 When true, input-channel instances are automatically declared as DirectChannel instances when not explicitly found in the application context.
2 Sets the default number of subscribers allowed on, for example, a DirectChannel. It can be used to avoid inadvertently subscribing multiple endpoints to the same channel. You can override it on individual channels by setting the max-subscribers attribute.
3 This property provides the default number of subscribers allowed on, for example, a PublishSubscribeChannel. It can be used to avoid inadvertently subscribing more than the expected number of endpoints to the same channel. You can override it on individual channels by setting the max-subscribers attribute.
4 The number of threads available in the default taskScheduler bean. See Configuring the Task Scheduler.
5 When true, messages that arrive at a gateway reply channel throw an exception when the gateway is not expecting a reply (because the sending thread has timed out or already received a reply).
6 A comma-separated list of message header names that should not be populated into Message instances during a header copying operation. The list is used by the DefaultMessageBuilderFactory bean and propagated to the IntegrationMessageHeaderAccessor instances (see MessageHeaderAccessor API) used to build messages via MessageBuilder (see The MessageBuilder Helper Class). By default, only MessageHeaders.ID and MessageHeaders.TIMESTAMP are not copied during message building. Since version 4.3.2.
7 A comma-separated list of AbstractEndpoint bean names patterns (xxx*, xxx, *xxx or xxx*yyy) that should not be started automatically during application startup. You can manually start these endpoints later by their bean name through a Control Bus, by their role with the SmartLifecycleRoleController (see Endpoint Roles), or by Lifecycle bean injection. You can explicitly override the effect of this global property by specifying auto-startup XML annotation or the autoStartup annotation attribute or by calling AbstractEndpoint.setAutoStartup() in the bean definition. Since version 4.3.12.
8 A boolean flag to indicate that default global errorChannel must be configured with the requireSubscribers option. Since version 5.4.3. See Error Handling for more information.
9 A boolean flag to indicate that default global errorChannel must ignore dispatching errors and pass the message to the next handler. Since version 5.5.
10 The default number of milliseconds for request and reply timeouts in endpoints. Default value is 30 seconds to avoid indefinite blocking. Can be configured to a negative value to restore infinite blocking behavior in endpoints. Since version 6.2.

These properties can be overridden by adding a /META-INF/spring.integration.properties file to the classpath or an IntegrationContextUtils.INTEGRATION_GLOBAL_PROPERTIES_BEAN_NAME bean for the org.springframework.integration.context.IntegrationProperties instance. You need not provide all the properties — only those that you want to override.spring-doc.cn

Starting with version 5.1, all the merged global properties are printed in the logs after application context startup when a DEBUG logic level is turned on for the org.springframework.integration category. The output looks like this:spring-doc.cn
