org.springframework.scheduling.annotation@async引发服务器错误

Question

@Async
public void DoAsynOperation(String param) {
                   restTemplate.exchange("URL", HttpMethod.PUT, entity,Object.class, parameters);
}

@Override
public void callingFunction(String abc) {
    DoAsynOperation(abc);
}

[dispatcherServlet]:路径为[]的上下文中servlet[dispatcherServlet]的servlet.service（）引发异常[请求处理失败；]

对此有什么意见吗？

您必须允许servlet配置

例如：

public class WebAppInitializer implements WebApplicationInitializer{

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
          AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
            ContextLoaderListener contextLoaderListener = new ContextLoaderListener(ctx);
            servletContext.addListener(contextLoaderListener);
            ctx.register(WebConfig.class);
            ServletRegistration.Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx));
            servlet.setLoadOnStartup(1);
            servlet.addMapping("/");
            servlet.setAsyncSupported(true); // For Allow Async Calls
            servlet.setInitParameter("dispatchOptionsRequest", "true");

    }

请检查您的配置
