同步方法在smtp java中不起作用

Question

我试图在使用smtp java发送邮件的同时制作Aysnchronous方法，但它总是引发异常

[SimpleAsyncTaskExecutor-3] ERROR             
o.s.a.i.SimpleAsyncUncaughtExceptionHandler -
    Unexpected error occurred invoking async method 'public java.lang.String
com.vedanta.vpmt.web.service.EmailLogService.sendEmailNotification(java.lang.String,java.lang.String,java.lang.String,java.lang.String)'.
java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.  at
