server by the parametric parsing mechanism. We can change the previous http/get mode of the Key=value to directly by the/value1/value2 way to pass, thus realizing the dynamic page static URL form. Caching only needs to be preceded by a cache server, for example: Squid. Dynamic caching of Web site dynamic content can be achieved. This is the most advanced Web site development technology, the realization of a real sense of software engineering, the

First of all, a simple personal understanding of nginx, in fact, Tomcat itself can complete the deployment of Web engineering, so Nginx is actually acting as a proxy server, Nginx listening port (for example, 80) to send received requests to localhost : 8080, and the latter is the Tomcat address. After Tomcat finishes processing the request, it returns to the client after Nginx. Next, install the Nginx,tomcat,mysql, the tutorials are available onli

monitoring, and so on, which are very similar to AWT. Developing your GWT application using eclipse requires preparing your environment. 1) Eclipse3.3 or above (2) need JDK1.4 or above version; 3 need GWT's Webtoolkit current version is 1.6.1;4) need the latest version of GWT SDK currently is 2.4. Second, GWT engineering structure detailed A new GWT project will have the following structure: 1.SRU directory storage source code; 2.client directory is

Debugserver are established, we can use LLDB to debug the application of the micro-letter. Four, Hopper + lldb In the previous blog, "iOS reverse engineering to WeChat Shell" we have to the micro-letter can be shelled, so the use of hopper processing is no problem. In this part, we will combine Hopper and lldb to play the role of combining the two swords together. This part of the blog is also part of the actual combat. 1. View the WeChat in the

When using PowerDesigner reverse engineering to generate PDM, column annotations (columncomment) are never generated, after several hours of exploration, find a compromise method, now share the following. And hope that there is a better way to guide the master. The month of invitation is PowerDesigner 15.2, the database is SQL Server 2008 R2 The method is as follows: 1, in the PowerDesigner interface-file-reverse engineer-database, and then select a D

at command line: Java-jar A.jar. Enough detail, hope can help you O (∩_∩) o haha ~ The should be noted for running Java Engineering on a Linux server. 1: On Linux:/etc/profile set classpath Configure the correct jar path. 2: The local Java project into a jar package. For example: 1.jar 3: Upload the Java project included jar packs and the jar packages in step 2 to the development directory. such as 2.jar Run java-classpath/usr/javalib/1.jar:/

Using PowerDesigner reverse engineering to guide the data Model diagram is very convenient, take Powerdesigner11 and Oracle8i as an example (other versions slightly different) The basic steps are as follows: 1, open or create a new Physicaldatamodel file (. pdm), (the DBMS is Sybase as Anywhere 9, or a DBMS that can select its own version of the database in the Drop-down list, such as Oracle version 8i (8.1.5)) 2. menu item Database->configure connect

Wrote a small tool in Java, using MAVEN Java engineering. When you are finished, you want to package into an executable jar package.Use Maven's plugin maven-assembly-plugin Add in Pom.xml To execute a command: MVN Clean Compile Assembly:single Generate Maventestapp-1.0-snapshot-jar-with-dependencies.jar in target folderThis jar pack is the executable jar, and can be executed with the command Java-jar Path\jarfile.Note: Compile must be assembly:sing

comments are insufficient, at least the refactoring to understand the code very well. Focus Practical engineering application, the focus is how much manpower, the goal effect how, to see the various projects different arrangements for different time. Not a round of reconstruction, you can modify all kinds of problems, but the focus is different, the key part must be all modified, other parts according to time, manpower, etc. adjust the strategy at a

Talk MyEclipse create a MAVEN Web project. The steps are as follows: 1. New-project Select Maven Project 2, click Next, Tick creat a sample .... 3. Next 4, click Finish can. 5. Configure as Web Engineering Right-click on our project, select Properties and find Project Facets Click on the OK item will be more than a Webroot folder, the inside of the Meta-inf,web-inf etc are copied to the above WebApp 6, modify the publishing rules,

external storage, and their lifecycle ends when the interaction completes. To make the interaction between classes simple and clear, the interface control class is only related to interface classes, use case control classes, interface control classes should not be related, interface classes rely on interface control classes, and interface control classes rely on use case control classes. The actions and properties of the interface control class can be defined when you design the sequence diagra

The code execution effect diagram is as follows: The production of "Vc/delphi Engineering parser" comes down to the reason of my job role. Because my department is the SQA department, in order to promote the testing work of effective and substantial progress, I would like to develop a suitable for this project team Test tools. In addition to my actual learning process also used c++test test tools, according to these I wrote down the project, as the

Each BSP has an engineering document, such as Mybsp.pbcxml, which describes the BSP information. Here is a description of the BSP Pbcxml file. The approximate format of the file should be this: …. … … … … … In fact 1. Here is not too much to introduce, a look should be understood, the following for the actual BSP used in the description of the example: 2. … Here's what you need to explain: Vendor: Name

Shenzhen team to develop a system in the North China side to push customers, in a patch, due to changes in the data dictionary, but the Shenzhen team did not give the database update script, only to the new version of the database creation script, in order to ensure that the client system has no loss of data, Can only find a way to do it: using PowerDesigner to reverse the new version of the database, apply this model to the existing database, the PowerDesigner will compare two versions of the d

In the software development process, the analysis is finished, is the software design. The design phase of software engineering includes: design, code writing and software testing. One: Software design Two: Coding The video has learned some coding principles and structured programming, and how to improve the efficiency of the code and reduce the complexity of the program. The theory is quite many. The video says: The Structured programming lang

If there is an intersection between the delta packages and is not well handled, then the overall system analysis must be done, the model will be developed after the refinement of the method is more appropriate to the requirements of the software development process often changed 1. The system is easy to break apart. 2. The development of manpower is relatively small. 3. Especially suitable for commercial software (such as QQ, onl
