Spring BOOT错误

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:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'defaultServletHandlerMapping' defined in class path resource [org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.HandlerMapping]: Factory method 'defaultServletHandlerMapping' threw exception; nested exception is java.lang.IllegalArgumentException: A ServletContext is required to configure default servlet handling

我的主班:

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());

}

}

}

不知道是什么原因导致此错误:创建名称为“

defaultServletHandlerMapping”的bean时出错。我没有任何@EnableWebMvc注释。

任何反馈 ?

回答:

@EnableAutoConfiguration也对WebMvc进行自动配置,因此请排除此情况:-

@EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class,WebMvcAutoConfiguration.class })
