spring boot项目pom文件中添加以下依赖

<!--https://mvnrepository.com/artifact/ws.schild/jave-core--><dependency><groupId>ws.schild</groupId><artifactId>jave-core</artifactId><version>3.1.1</version></dependency><!--以下依赖根据系统二选一--><!--win系统平台的依赖--><dependency><groupId>ws.schild</groupId><artifactId>jave-nativebin-win64</artifactId><version>3.1.1</version></dependency><!--linux系统平台的依赖--><dependency><groupId>ws.schild</groupId><artifactId>jave-nativebin-linux64</artifactId><version>3.1.1</version></dependency>

Java单类实现代码,复制到Spring boot项目中
