app.module.ts文件添加两行代码：

import { LocationStrategy, HashLocationStrategy } from '@angular/common';

    @NgModule({
     
        providers: [
     
        { provide: LocationStrategy, useClass: HashLocationStrategy },
     
        ]
     
    }）

解决方法2:

在springboot项目application中添加

    @Component
    public class WebConfig implements ErrorPageRegistrar {


        @Override
        public void registerErrorPages(ErrorPageRegistry registry) {
            ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND, "/");
            registry.addErrorPages(error404Page);
        }


    }
