I have solved the above problem, but the background will find that globaleventexecutor threads will be added every time a method is requested to be written. How do you close these threads to free system resources. {color:#ff8b00}*MY CODE:*{color}
{code:java}
public void writePLC(String dbName, String dbValue) {
// PooledPlcDriverManager.PoolCreator poolCreator;
PlcDriverManager driverManager = new PlcDriverManager();
// PlcDriverManager driverManager = new PooledPlcDriverManager(poolKeyFactory);
try {
//
/**
* 在多个服务之间共享连接时，请确保共享 的实例，否则将导致具有多个池。
*/
//
// driverManage = new PlcDriverManager(this.getClass().getClassLoader());
plcConnection = driverManager.getConnection(connectionIp);
if (!plcConnection.isConnected()) {
// writePLC(dbName, dbValue);
return;
} else {
// plcConnection.connect();
PlcWriteRequest.Builder writeRequestBuilder = plcConnection.writeRequestBuilder();
// SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
writeRequestBuilder.addItem(dbName, dbName, dbValue);
// System.out.println(var);
System.out.println("开始写入");
/*-------------- 异步方式 ------------------------*/
PlcWriteRequest writeRequest = writeRequestBuilder.build();
// PlcWriteResponse response = writeRequest.execute().get(10, TimeUnit.SECONDS);
CompletableFuture<? extends PlcWriteResponse> asyncResponse = writeRequest.execute();
asyncResponse.whenComplete((response, throwable) -> {
System.out.println("写入成功");
for (String fieldName : response.getFieldNames()) {
if (response.getResponseCode(fieldName) == PlcResponseCode.OK) {
log.info("Value[" + fieldName + "]: updated");
System.out.println("Value[" + fieldName + "]: updated ->" + S7DTO.getPlcMap().get(fieldName));
}
// Something went wrong, to output an error message instead.
else {
log.error("Error[" + fieldName + "]: " + response.getResponseCode(fieldName).name());
}
}
