Java中注解@Async实现异步及导致失效原因分析

   import org.springframework.context.annotation.Configuration;
   import org.springframework.scheduling.annotation.EnableAsync;
   @Configuration
   @EnableAsync
   public class AsyncConfig {
       // 异步方法的配置类，确保@EnableAsync开启异步方法执行的支持
   }

   import org.springframework.scheduling.annotation.Async;
   import org.springframework.stereotype.Service;

   @Service
   public class EmailService {

       @Async
       public void sendEmail(String recipient, String message) {
           // 异步发送邮件的逻辑
           System.out.println("Sending email to " + recipient);
           // 实际的邮件发送逻辑
       }
   }

   import org.springframework.beans.factory.annotation.Autowired;
   import org.springframework.stereotype.Controller;
   import org.springframework.web.bind.annotation.GetMapping;
   import org.springframework.web.bind.annotation.RequestParam;
   import org.springframework.web.bind.annotation.ResponseBody;

   @Controller
   public class MyController {

       @Autowired
       private EmailService emailService;

       @GetMapping("/sendEmail")
       @ResponseBody
       public String handleRequest(@RequestParam String recipient, @RequestParam String message) {
           emailService.sendEmail(recipient, message);
           return "Email sent asynchronously";
       }
   }
