只能存在一个AsyncConfigurer Spring Boot
只能存在一个AsyncConfigurer Spring Boot
提问于 2018-05-16 15:18:52
我在我的spring boot应用程序中使用了@Async注释。我有两个AsyncConfigurer Bean 1的定义，一个在我的应用程序2.库jar文件中。如何从库jar文件中覆盖或禁用asyncconfigurer，并使用我在应用程序中指定的文件。
目前我得到了下面的错误，如果我从库jar文件中删除bean定义，它可以正常工作。
请找到下面的堆栈跟踪：-

您可以尝试排除来自ComponentScan上的库的类
@ComponentScan(basePackages = "your package",
excludeFilters = {
@Filter(type = ASSIGNABLE_TYPE,
value = {
AsyncConfigurerFromLibrary.class
})
