配置响应在Spring启动应用程序上提供 [英] Configure react to be served on Spring boot app

问题描述

到目前为止，我一直在为我的Spring启动应用编写一堆端点，没有html UI端。现在，我想提供包含反应代码的HTML文件和js文件。

So far, I've been writing a bunch of endpoints for my Spring boot app, with no html UI side. Now, I want to serve the HTML file and js files which contain react code.

当我访问 http：// localhost：8443 我得到：

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
Not Found

到目前为止我做了什么：

What I did so far:

1.增加了一个扩展的Web配置类 WebMvcConfigurerAdapter ：

1.Added a web config class that extends WebMvcConfigurerAdapter:

@EnableWebMvc
@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {
    @Bean
    public ViewResolver internalResourceViewResolver() {
        InternalResourceViewResolver bean = new InternalResourceViewResolver();
        bean.setPrefix("/resources/static/");
        bean.setSuffix(".html");
        return bean;
    }
}

2.增加了一个休息控制器端点：

2.Added a rest controller endpoint:

@RestController
public class HomeController {

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public ModelAndView getdata() {
        ModelAndView model = new ModelAndView("index");
        return model;
    }
}

我有 myproject / src /main/resources/static/index.html 我项目中的文件。

推荐答案

Spring Boot can自动处理静态文件（按照惯例），只需将所有html，js，css等文件放到 src / main / resources / static 中，删除你的ViewResolver和Controller对于'/'并且它将起作用， index.html 也将被Spring Boot映射到 / 。

Spring Boot can automatically handle static files (by convention), just put all of your html, js, css, etc. files to src/main/resources/static, remove your ViewResolver and Controller for '/' and it will work, index.html will also be mapped to / by Spring Boot as well.

除此之外，您当然可以通过使用正确的 @RequestMapping 来创建带有api前缀的REST端点你的 @RestController s

Besides this, you can of course make REST endpoints with the api prefix by just using the correct @RequestMapping on your @RestControllers
