Between all the bean dependencies, all assembled using XML to describe the relationship itself will lead to XML read and modify certain difficulties. And XML configuration itself can not be directly used for unit testing to verify dependencies. Therefore, when the bean, when more complex relationship between, XML configuration file itself is a burden to maintain. I personally look forward to the Spring to use scripting language to write and assemble the relationship between the bean, so that assembly of the script itself can be tested, and the description ability of the script is much better than the XML configuration file, but it still write and maintain easily than XML.
Dell PE 2900 with 5U tower structure, high: 21.77 cm; Width: 44.27 cm; depth: 67.43 cm, although hosted on this structure occupy a large space than the rack, takes 1 to 3 is more suitable for use in the enterprise server applications , but also provides better scalability and rich redundancy. Lets look at the specific Dell PE 2900 series in the scalability and redundancy on good design. PE 2900 Series comes standard with 930 watts of power a non-redundant hot-plug, you can automatically switch General 110/220 volts. If you need the server 24 x 7 uninterrupted operation, the server components for dual power supply to ensure stable and adequate, PE 2900 can also select dual redundant hot-swappable 930 watt power supply. This continuous running on the server at the same time, lasting for the entire system to provide sufficient power to ensure stable operation of the various parts of the hardware.
