我正在使用Spring BOOT运行一个简单的桌面应用程序。下面是错误堆栈：Spring BOOT出错

package com.pb.relay;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.retry.annotation.EnableRetry;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
@Configuration
@ComponentScan
@EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class })
@EnableAsync
@EnableRetry
@EnableScheduling
public class RelayDesktopApp {
public static void main(String[] args) {
try {
SpringApplication app = new SpringApplication(RelayDesktopApp.class);
app.setHeadless(false);
app.run(args);
} catch (Throwable t) {
System.err.println(t.getMessage());
}
}
}不知道什么是此错误的原因：错误创建豆与名称为'defaultServletHandlerMapping'。 我没有任何@EnableWebMvc注释。
有没有反馈意见？
