请求路径@PathVariable注释中有点.英文句号的问题（忽略英文句号后面的后缀）

前端页面请求地址

<video id=example-video width=960 height=540 class="video-js vjs-default-skin" controls>
        <source
                src="/media2/course.m3u8"
                type="application/x-mpegURL">
    </video>

后台代码

    @RequestMapping(value = "/media2/{id}.m3u8")
    public String m3u8Generator(@PathVariable("id") String id)
    {
        System.out.println(id);
        return "xxx";
    }

后台得到的id结果是course

解决方法

@Configuration
public class WebAppConfig extends WebMvcConfigurerAdapter {

    /***
     * Using the @PathVariable on a Spring Boot controller, if a value contains a dot (‘.’) the value after the dot will be truncated.
     * This happen since Spring MVC considers anything after the last dot as
     * <a href="https://stackoverflow.com/questions/3526523/spring-mvc-pathvariable-getting-truncated">a file extension by default</a>.
     *
     * In order to avoid to getting truncated values it can be disabled this Spring MVC “feature” setting to false the
     * useSuffixPatternMatch option through the PathMatchConfigurer:
     * @param configurer
     */
    @Override
    public void configurePathMatch(PathMatchConfigurer configurer) {
        configurer.setUseSuffixPatternMatch(false);
    }
}
