First, the cattle out of the interview questions are as follows:

1. Struts, spring, hibernate this open-source framework, where the limitations of their history? Under what circumstances would not fit the frame?

2. If you want to design a search engine like google, as there are only two pages, requiring maximum performance, web aspects of how to design? (No need to consider the logic of the search)

3. If you want to design a small router for web system, how to design?

4. Please rate the following web framework you are familiar with how the testability, struts, springMVC, webwork or other can be. Under what conditions can the introduction of automated testing of web systems? Please describe a comprehensive web-oriented framework for automated testing system should have features.

5. Enterprise applications, which special requirements? The circumstances in which we do not consider these requirements?

6. You were the R & D process is like? If you come from the design and development process, whether it can significantly improve the productivity and development quality? If so, it is reflected in what areas? If not, where is the bottleneck?

Second, cattle were the following thread seems to be another one of their own to answer, as follows:

1. Struts, spring, hibernate this open-source framework, where the limitations of their history? Under what circumstances would not fit the frame?
struts is based on a request to answer it. ajax, flash and other rich client more and more .....
java spring is due to the static type of restrictions, such as java to support dynamic method to add after the .....
hibernate is because the database is relational, object-oriented databases such as after the .....
In summary ... ssh Bengda can not get.

2. If you want to design a search engine like google, as there are only two pages, requiring maximum performance, web aspects of how to design? (No need to consider the logic of the search)
Performance:
1 client: js of writing, data alignment, differences between different browsers.
2 server: Logic, calculation, caching, to reduce I / O, improving the hit
3 Transmission: bandwidth, cache, asynchronous, progress bars, concurrency, clustering, data compression.
I think the most important properties of the human experience, the other is to go into second place.

3. If you want to design a small router for web system, how to design?
Concurrent use of multiple threads do not need a simple file server directly to change after the submission of documents.
Exception does not use conventional methods to capture
(Due to selective small they simply can not use exceptions, only soft and hard reset)

4. Please rate the following web framework you are familiar with how the testability, struts, springMVC, webwork or other can be. Under what conditions can the introduction of automated testing of web systems? Please describe a comprehensive web-oriented framework for automated testing system should have features.
So the container restrictions: web, spring, hibernate is not a good test.
Since most people experience is web-based. Subjective concept into code generation tool costs are too high because the pages do not have enough testing support. It is very difficult to write code to automate procedures

Existing seleniumIDE is not very stable if the html, js, css to separate page content to transmit to json or xml, the page logic from the second brightly dyed js type test costs will drop so much .....
(Development costs increased by 2 to 5 times)

5. Enterprise applications, which special requirements? The circumstances in which we do not consider these requirements?
, Performance, scalability, 7 * 24 hours
Performance issues in the event of performance problems without considering the scalability issues before signing the long-term maintenance, does not consider until the second phase development contract
7 * 24 work systems development are generally not considered in itself ...

6. You were the R & D process is like? If you come from the design and development process, whether it can significantly improve the productivity and development quality? If so, it is reflected in what areas? If not, where is the bottleneck?
...................... ......... I designed
Bottleneck in large part because of the courage to try the new practice.
