More and more websites are developed for mobile browsing using responsive layout. There are many applications that already do this. Today I finally found a template that looks good and usable on the Internet, and it is very clean, JS
Basically, we only use jquery, not jquery mobile, don’t get me wrong. Other js
The framework is basically useless, so this is the best thing for developers. They can use clean templates directly. Not much to say, just look at the picture and see the effect. Personally, I think this template is still very valuable for those in need…Read more

Try to use python to write a deployment tool in the project. First, you will use python to call svn.
Some commands were used to download codes, etc., but coding errors were reported at first, and then a solution was found. Make a note, the solution is simple. [Code snippet] Just set the environment variables above.

As long as it is an Android device, the popular devices on the market generally have back button, home button, menu button, volume up, volume down and other buttons. In the test example, it is just a simple capture and release of the key
key messages and change some basic functions. However, you should be particularly careful when overriding these methods, because this will affect the user experience of the Android system, so some methods in many new APIs cannot be changed or
Only some specific methods can be implemented. Environment: JDK 1.7Eclipse 4.2 JunoAnd…Read more

Lately I can’t calm down and do something, including work. I sometimes have random thoughts every night and even have insomnia. It’s the same tonight. I was so unhappy that I could only complain about it online. Although I have never studied Chinese since high school, I still
I want to write something and record my current mood. If you see someone who is engaged in literature, just leave. I plan to write a series, and the name is defined as One Person’s Strange City. I’m in a bad mood today. Let me write an opening before going to bed: Pay tribute to the diaosi.******

Java

Multiple applications are deployed in Tomcat, but there are dependencies between these applications. For example, application A depends on the Core application, and application B also depends on the Core application. It must be in the Core application.
Application A can only be started after the application is started, otherwise an error will be reported. The reason is that when A starts, it will call Core’s API to do some things, so the startup order must not be reversed, but usually tomcat is used
The application’s war package is placed in the webapps directory, but if all applications are placed in this directory, there is no way to control the application…Read more

During this period, we need to make a POC to demonstrate to customers. There happens to be a function that needs to be pushed from the server to the client, which is similar to mobile development for Android and iOS.
The functions are the same, but they need to be implemented on the web page. What I see most on the Internet is the introduction of comnet technology. Many web chat or consultation functions are implemented using this technology. Of course, HTML5
Websocket is definitely supported, but it takes some time to learn it, and POC time is tight, so I finally used DWR to implement it. DWR was used to implement it many years ago… Read more

Java

When writing a background program, sometimes you need to know whether the client is sending a normal request or an ajax request, at least in the project I am currently doing.There is such a use in the project: if session
When it expires, if it is a normal request, it will jump to the login page, but if it is an ajax request, if the background session has expired, the html code of the login interface will be returned as ajax.
The return value is very depressing and difficult to handle. If it is an ajax request, the ideal way is to return json to the client.

I have previously tested the most basic method of dynamically loading a class from a local file and the most basic method of dynamically loading a class in Java. Today I will test a method of dynamically loading a class from the Internet.
The most important thing is to use: URLClassLoader. Suppose there is such a class: [code snippet] This class is finally packaged into test.jar. The first method dynamically calls this jar
There is also a method in this class in the package [code snippet], which is implemented through the getResourceAsStream method [code snippet]

When writing programs in Java, you can get a lot of useful information through Httprequest, including the full path of the URL, such as host or domain name, port, and context.

Dynamically loading a class is to load the class when needed at runtime. This is a very important mechanism in large systems, that is, using lazy mode, loading when needed instead of applicatio
n The server loads many classes when it starts. Of course, the most important technology for dynamically loading classes is to apply Java’s reflection mechanism (implemented by Java reflection).
In addition, many systems adopt plug-in development and deployment. In such cases, dynamically loading classes becomes more important.

Using some methods in apache.commons.io to operate files will reduce a lot of burden on programmers. The FileUtils class is often used for file operations. Today, we will introduce some of the most commonly used methods.
There is no way to make a summary. Of course, for the most comprehensive thing, you should look at the documents or examples of apache.commons.io. contentEquals(File file1, File
file2): Compare the contents of two files and return whether their contents are the same.copyDirectory…Read more

When writing an android app, you usually need to communicate with the server to obtain data, and the transmission of these data is usually completed through the HTTPS protocol, which is simply http + ssl.
To complete, from the perspective of the server, it has nothing to do with development, only related to the configuration of the application server. The following document explains in detail how to use android app
