Springboot+Vue前端刷新404的解决方法

Springboot+Vue前端刷新404的解决方法

原因是因为没有定义404的页面，只需要在Springboot中加入如下代码即可

import org.springframework.boot.web.server.ConfigurableWebServerFactory;
import org.springframework.boot.web.server.ErrorPage;
import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpStatus;

@Configuration
public class ServletConfig {
    @Bean
    public WebServerFactoryCustomizer webServerFactoryCustomizer() {
        return factory -> {
            ErrorPage errorPage = new ErrorPage(HttpStatus.NOT_FOUND,"/index.html");
            factory.addErrorPages(errorPage);
        };
    }
}
