The different transaction isolation levels in 5 are defined in spring:1.Isolation_default(This configuration can be used in general); This is a Platfromtransactionmanager default isolation level that uses the default transaction isolation level of the database.2.isolation_read_uncommitted(uncommitted) This is the lowest level of isolation for transactions, and it allows a transaction to see uncommitted data for that transaction.This isolation level produces dirty reads, non-repeatable reads, and

synchronous operation----can use various methods of the deferred object to specify a callback function.Let's look at a concrete example. Suppose there is a time-consuming operation, wait:var wait = function () {var tasks = function () {alert ("Execution complete!　　　　");　　　　};　　SetTimeout (tasks,5000); };However, by doing so, the done () method executes immediately, not the function of the callback function. The reason is that the $.when () parameter

!") "); }; SetTimeout (tasks,5000); }; We specify a callback function for it, what should we do?Naturally, you will think that you can use $.when (): $.when (Wait ()) . Done (function () {alert ("Haha, success! "); }) . Fail (function () {alert ("Error! "); }); (Run code example 5) However, by doing so, the done () method executes immediately, not the function of the callback function. The reason is that the

! "); }) . Fail (function () {alert ("Error! "); }); (Run code example 4) This code means that you perform two operations $.ajax ("test1.html") and $.ajax ("test2.html"), and if all succeeds, run the callback function specified by done (); fail () if one fails or fails The specified callback function.V. Normal operation callback function interface (upper)The biggest advantage of the deferred object is that it extends this set of callback function interfaces from Ajax operations to a

Let's look at a concrete example. Suppose there is a time-consuming operation wait: The code is as follows Copy Code var wait = function () {var tasks = function () {Alert ("Execution complete!")

Before you deploy Docker, you need to preview the Docker command Docker basic command Docke pull nginx# Download Nginx mirrors Docke Push 192.168.161.117:5000/os/centos #上传本地制作的镜像到本地镜像库 Docker Images #查看下载到本地的镜象 Docker tag 980E0E4C79EC 192.168.161.117:5000/os/centos #将Image ID mirrored to 980E0E4C79EC mirror marked as 192.168.161.117:5000/os/ Centos Docker run-it

the database. Dirty reading, non-repetition reading, phantom reading (1) Dirty reads: dirty reading means that when a transaction is accessing the data and the data has been modified and the modification has not been submitted to the database, another transaction accesses the data and then uses the data. For example: John's salary is 5000, and his salary is changed to 8000 in transaction a, but transaction a has not yet been submitted. Meanwhile

1.Docker Registry Description This article records the personal complete construction Docker registry operation Process, although the official provided the Docker hub as an open centralized storehouse, but the celestial network is conceivable, the first time pull a mirror not to fail is the time is very long, To solve this problem, you need to create a private warehouse to pull local push. The Docker version I use is: 1.5.0 2. Installation Docker-registry The code is as follows: Docker run-d

The distribution of data is mainly determined by the partition value.The DYNAMODB service is solely responsible for the management of the partition, including the number of start table partitions and partition splitting.First we need to know that a partition in Dyna

Analysis of private property inheritance issues in php classes. Take a closer look at this sentence if the parent class has private attributes. The method of the parent class serves only the private attributes of the parent class. The following is a series of columns to deepen understanding. this example looks odd. please read this sentence carefully if the parent class has private attributes. The method of the parent class serves only the private attributes of the parent class. The following de

sample, which includes the basic user registration. Get the code base from this GitHub repository. Once you have created and activated the VIRTUALENV, run the following command to get started quickly: $ pip install-r requirements.txt$ export app_settings= "project.config.DevelopmentConfig" $ python manage.py create_db$ Python manage.py db init$ python manage.py db migrate$ python manage.py create_admin$ python manage.py runserver With the app running, visit the Http://localhost:

LAN switches have evolved from a HUB-based LAN shared in the traditional sense to a broader space. Take Cisco's Catalyst 5000 Series LAN switch as an example. It includes an integrated switching hardware structure, 10-Mbps Ethernet that supports switching, and-Mbps Fast Ethernet, supports fast Ethernet, FDDI, exchange-type ring, and layer-3 switching processing. This type of switch can provide exchange access to workstations, servers, network segments

configuration file. You can copy and paste the content of Gist directly. Next, add a Procfile under the root directory of the project so that you can use foreman to start the application. The content is as follows: Copy codeThe Code is as follows: web: bundle exec unicorn-p $ PORT-c./config/unicorn. rb Now run the foreman start command to start the application. Everything will run normally and you will be able to see a running application on http: // localhost:

First, this question is a bit problematic because the private attribute cannot be inherited. please read this sentence carefully if the parent class has private attributes. The method of the parent class serves only the private attributes of the parent class. The following describes how to use a series of columns. This example looks strange. a new attribute $ sal is defined in the subclass, but the system returns the attribute of the parent class. The code is as follows: Class employee {Pri
