Java Spring引导抽象自动配置问题

使用spring boot同时运行activiti和web套接字时，我出现以下错误：

Parameter 0 of method springAsyncExecutor in org.activiti.spring.boot.AbstractProcessEngineAutoConfiguration required a single bean, but 4 were found:
- clientInboundChannelExecutor: defined by method 'clientInboundChannelExecutor' in class path resource [org/springframework/web/socket/config/annotation/DelegatingWebSocketMessageBrokerConfiguration.class]
- clientOutboundChannelExecutor: defined by method 'clientOutboundChannelExecutor' in class path resource [org/springframework/web/socket/config/annotation/DelegatingWebSocketMessageBrokerConfiguration.class]
- brokerChannelExecutor: defined by method 'brokerChannelExecutor' in class path resource [org/springframework/web/socket/config/annotation/DelegatingWebSocketMessageBrokerConfiguration.class]
- messageBrokerTaskScheduler: defined by method 'messageBrokerTaskScheduler' in class path resource [org/springframework/web/socket/config/annotation/DelegatingWebSocketMessageBrokerConfiguration.class]


Action:

Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

由于spring boot使用抽象配置，我是否必须覆盖某些配置

感谢您的帮助。

这可能是Activiti自动配置类中的一个bug。这取决于它们在应用程序上下文中只是一个

TaskExecutor

bean，或者，如果有多个bean，则其中一个bean是主bean

您应该能够通过声明自己的

TaskExecutor

bean并将其标记为

@Primary

:

@Configuration
class SomeConfiguration {

    @Primary
    @Bean
    public TaskExecutor primaryTaskExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        // Customize executor as appropriate
        return executor;
    }

}

很好，通过创建我自己的TaskExecutor作为主要任务执行器，它成功了。所以你是对的，这是Activiti的自动配置类中的一个bug。
