Java spring boot 开发中控Live10R指纹采集器linux（指纹登录系统）

1.需求

需要做一个指纹登录系统，录入指纹，修改指纹等，指纹比对等。

2.开发

开启指纹采集器，指纹采集器base64数据录入到数据库以及指纹登录登出

定时器循环更新指纹（需求多个指纹采集器，一个录入采集器，一个比对采集器）

private long mhDB = 0;/*** 循环录入指纹*/@Scheduled(fixedRate = 30000)public void fpRealTimeEntry() {// 获取所有录入过指纹的打开后直接录入EntityWrapper entityWrapper = new EntityWrapper();entityWrapper.eq("device_type", "smt");entityWrapper.eq("status", "1");List<User> list = userMapper.selectList(entityWrapper);int ret = FingerprintSensorErrorCode.ZKFP_ERR_OK;if (0 == (mhDB = FingerprintSensorEx.DBInit())) {log.error("初始化数据库失败, 状态！ = " + ret + "!");return;}for (User fp : list) {if (StringUtil.isNotBlank(fp.getFingerPrintBase64())) {String regTemps = fp.getFingerPrintBase64();int number = Double.valueOf(fp.getNumber()).intValue();byte[] decoded = Base64.decodeBase64(regTemps.getBytes());int i1 = FingerprintSensorEx.DBDel(mhDB, number);System.out.println("删除当前指纹"+i1);int i = FingerprintSensorEx.DBAdd(mhDB, number, decoded);System.out.println(i);}}}

3. 打包发布

运行zkdemo注意环境的坑

Java环境配置：

export JAVA_HOME=/home/java/jdk1.8.0_291
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib:wq!// 刷新一下
source /etc/profile

打jar包，
