springboot使用oshi监控应用系统

1. 引入依赖

		
            com.github.oshi
            oshi-core
            3.9.1
        
        
            net.java.dev.jna
            jna

4. 测试

public static void main(String[] args) throws Exception {
        Server server = new Server();
        server.copyTo();
        System.out.println(JSON.toJSONString(server));
    }

输出：
