Java SourceDataLine 播放音频

项目	Value
音频格式 添加依赖
*.wav	(JDK 原生支持)
*.pcm	(JDK 原生支持)
*.au	(JDK 原生支持)
*.aiff	(JDK 原生支持)
*.mp3	mp3spi.jar
*.flac	jflac-codec.jar

1 依赖

<dependency><groupId>com.googlecode.soundlibs</groupId><artifactId>mp3spi</artifactId><version>1.9.5.4</version>
</dependency><!-- 如果需要解码播放flac文件则引入这个jar包 -->
<dependency><groupId>org.jflac</groupId><artifactId>jflac-codec</artifactId><version>1.5.2</version>
