In the morning, I wrote a basic article of DWR, the afternoon saw Konghao teacher's dwr and SPRINGMVC integration video, I followed the hands of all kinds of ways to practice a bit, encountered some problems, record to yourself later when using DWR copy it. Method One: Each dry, the coupling degree is low Description: The way one encounters the least problem, c

This article mainly introduces how DWR simulates Google search results. If you are interested, you can understand it. It may be helpful for your DWR study. I will not talk much about it, but read the code. The Code is as follows:

mentioned it in my blog. We can consider Lucene. I didn't pick up the book to learn it over the past few days. During the course of reading the book today, compass was mentioned in the book, downloaded. but I haven't read it yet. Let's talk about it later. however, it is troublesome to create an index on a local machine because disk sharing is not suitable for the dual-machine solution of the existing system. Do you want to store the index in the database? Or is there another storage? (Not yet)

If you want to extract some strings from the item list, then fill them in the drop-down list. For example, a sample Java program is as follows: 12345678 PackageOnlyfun. Caterpillar;Public ClassOption {PublicString [] getoptions (){// In fact, these strings are found from the information...Return NewString [] {"Liangge", "Mao Meimei", "mi puppy "};}} In the response string column, you need to fill in the response to the drop-down list. Of course, first we need to develop this o

The principle of DWR:One, what is DWR?DWR: (Direct Web Remoting) is an open-source class library that helps developers develop Web sites that contain Ajax technology. It allows code (JavaScript) in the browser to use Java functions running on the WEB server as if it were in the browser .It consists of two main parts:A. Allow JavaScript to get data from a servlet (small application) that adheres to Ajax prin

If DWR is used, the effect is immediate. Although it may damage the MVC design pattern, its low-coupling programming method is as simple as developing a CS program. In the past, when I used ajax to write a program, the most time spent was the JS part. Now with DWR, I don't have to debug complicated JS and focus on the business logic, this will surely get twice the result! I just learned an entry-level insta

Background introduction: The project is a city credit Office system, before it seems to be a company in Shijiazhuang responsible. I belong to the halfway take over. After getting the source code, the project was set up according to the instructions they gave Jane (Shao) (de) Ming (ke) (lian). As a result, the project file is red. So we start to solve these mistakes, but many of them are similar. After some tinkering, most of the bugs were resolved, with a spring and
