Step1：在HTML中設置以下代碼
<audio autoplay="autoplay" controls="controls" hidden="true">
<source src="/upload/櫻花樹下的約定+(原版)+-+可澤,夏凌兮.mp3" type="audio/mp3">
<source src="/upload/wecanstop.mp3" type="audio/mp3">
<embed height="50px" width="100px" src="/upload/wecanstop.mp3">
</audio>
Step2：在springmvc配置里“匹配文件路徑”(注：文件的路徑只需要具體到音樂文件所在的文件夾就行)
//匹配文件的路徑
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/upload/**").addResourceLocations("file:c:/Users/.../music/");
}
