Measure function: can measure current, voltage, active power, reactive power, frequency, zero sequence current, electric energy, 2 pulse inputs implement watt-hour meter auto read;
测量功能:高精度测量电流电压、P、Q、功率因数、频率、零序电流、计算电度;2路脉冲量输入实现外部电度表自动抄表;
readOnly: Setting up a read/write transaction by specifying @Transactional(readOnly=false) will make the FlushMode of the persistence context AUTO.
readOnly:通过指定 @Transactional(readOnly=false) 建立读/写事务,这样会使持久化上下文的 FlushMode 变为 AUTO。
