In the previous article summed up the spring transaction configuration in 5, but many ways are not and all the parameters used in the configuration is the default parameters, this article on the two commonly used transaction configuration and information configuration transaction propagation, isolation level, and timeouts, and so on. I. Annotation-type transactions 1, the annotated transaction in peacetime development use quite a lot, the work of the

In front of us, we talked about the DNN, and the special case of DNN. CNN's model and forward backward propagation algorithms are forward feedback, and the output of the model has no correlation with the model itself. Today we discuss another type of neural network with feedback between output and model: Cyclic neural network (recurrent neural Networks, hereinafter referred to as RNN), it is widely used in natural language processing of speech recogni

}); throw new RuntimeException("运行期异常");} 1 When you test the Delete () method in the Personservicetest class, you see that the Eclipse console prints an exception and immediately looks at the person table and finds that the record with ID 4 has been deleted. Transaction propagation PropertiesTransactions also have some other characteristics, such as in the business Bean--personservicebean, some business methods do not need tr

Transactions are the guarantee of the atomicity of logic, and by using transaction control, it is possible to avoid problems such as dirty data caused by logical processing failure.The two most important features of a transaction are the level of communication and the data isolation levels of the transaction. The propagation level defines the scope of control of the transaction, and the transaction isolation level defines the scope of the transaction'

propagation_required, the default spring transaction propagation level, which is characterized by the addition of transactions to the transaction if a transaction already exists in the context, and the new transaction execution if no transaction exists in the current context. So this level is usually sufficient to handle most business scenarios. Propagation_supports, literally known, SUPPORTS, supported, the characteristic of this

1. transaction Propagation Behavior in the use of transactions, the most commonly used Propagation Behavior is require. In most mis systems, you can switch a require transaction to the entire business layer to meet your needs. However, spring provides not only this, but also the corresponding transaction Propagation Behavior for complex businesses to meet busines

http://blog.csdn.net/linmingan/article/details/50958304 The inverse propagation algorithm of cyclic neural networks is only a simple variant of the BP algorithm. First we look at the forward propagation algorithm of cyclic neural networks: It should be noted that there is only one weight matrix at the moment of the rnn to the current moment, and that the weight matrix has nothing to do with time. The diffe

Seven transactional propagation behaviors are defined in the Transactiondefinition interface. Propagation_required If there is a transaction, the current transaction is supported. If there is no transaction, a new transaction is opened. Default behavior Propagation_supports If there is a transaction, the current transaction is supported. If there is no transaction, the execution is non-transactional. However, for transaction managers with transactiona

To tell the truth, I heard the "event bubbling" when I was working, and it took a long time to get a general idea that the child DOM element and the parent DOM element were all bound to the same type of event, and if the child event triggers the parent, then this is called "event bubbling." However, if things are so simple, I believe I must have married mating, when the CEO. Bad is bad in the later heard an "event spread", is not "event bubbling", and then heard the "event model" ...

Formula for propagation delay of cabling in PCB The first half is information from altera. The propagation latency (tPD) is the time required to transmit a signal from one point to another. Transmission Line propagation delay is a function of the relative dielectric constant of materials. Propagation delay of micro-S

Dynamic taint Propagation MethodAnalysis of the two common security testing methods has some shortcomings in testing external input data. How can we perform a better security test on external input data? Dynamic taint propagation is proposed in the industry ).The dynamic pollution propagation
