Jdbctemplate was used in the project at the beginning. To improve the development efficiency, Hibernate was used. However, it was found that hibernate was not very efficient during batch operations. So now we use jdbctemplate and Hibernate to mix, jdbctemplate and hibernate can be mixed, there are several considerations.
1. If the jdbctemplate part only involves queries, you can use the hibernate application cache, that is, the second-level cache.
You've just seen the mix in the textbook order from the trip.Num is a conversion operator that converts character encodings to numbers.It converts the value of Registera Registerx to a number and assigns a value to Registera.The conversion process is byte-wise:00,10,20,30,40,... Converts the character to the number 0;01,11,21,31,41,... Converts the character to the number 1;02,12,22,32,42,... Characters into the number 2, and so on.If there is an ove

number that Tomcat uses by default is 8080, so there is a problem with ode using 8080 ports, and when Ode's host server Tomcat uses 8080 ports, Ode does not seem to be able to use the other ports and must use 8080 ports. If both the service API and BPEL are running on the same machine, and both are in the same Tomcat directory, there is a problem when deploying BPEL using ODE. A preliminary analysis, possibly a port number contention, has been tried many times to finally find a solution: Using
Below are some examples of PHP judgment strings in my favorites that are pure English, pure Chinese characters, or a mix of Chinese and English characters. For details, refer.
