Avoid complicated get/set operations excerpted from: Xia Xin hibernate_dev_guide To avoid complicated get/set operations, you can use the Apache Jakarta Commons Group The attribute bulk copy function (http://jakarta.apache.org/commons/beanutils/) provided by the piece. In the following example, we copy all the properties of the user object to the Anotheruser object: TUser user = new TUser (); TUser another

kung Fu, seriously understand what content can attract people's attention, and in the site constantly add new columns, finally, do not know where their focus, the theme of the site is increasingly unclear .... The development of the Internet today, should say that all aspects of content, if your site does not have enough characteristics and enough professional, then even if the information is large, for the browser is also a duplication of spam information, there is no special value to say. pri

Baidu every update, will bring a lot of new problems, this is the webmaster recently in the site optimization process of an assessment. Why is the rank promoted? Why the home page down right? Why aren't snapshots updated? And so on, it takes a lot of thought and time to analyze. 　　 (Can you see the meaning of this diagram?) Luoping in the Baidu update of the station group optimization summary, effect

URL path is the address of the site page, usually, a page only exists a valid address, so that the page is unique, but also for the search guide to judge the entrance of the page has provided help. But some programs themselves have dynamic, static, pseudo static. At the beginning of the website optimization, the webmaster can not first determine their own site to use which mode to do, with the dynamic, and then changed to pseudo Static, and then changed to static. Then the site page will certain

, the query execution time is too long. Some queries can take a long time to consume. If the query statement design is unreasonable or query design to the table and records for a long time, will make the query more lengthy execution. If there are times when a user needs to update or delete a record, a lot of locks will be acquired if the rows involved are more numerous. These locks block other queries, whether or not they are eventually upgraded to table locks. In general, do not mix long runn

to stop shipping and contact the buyer at the first time. If it has been shipped, and the goods can not be intercepted, sellers need to contact the buyer do not sign, to avoid the purchase of goods received and the risk of being signed. If the buyer is a long-term and trustworthy user, the seller may negotiate with him to return the payment because some of the issues in his PayPal account have been investigated and recovered. If PayPal verifies that

Environment: Windows 7+wamp server+mysql 5.7.9View MySQL default encoding: like ' character% ' Character_set_client is the client-side encoding method Character_set_connection the encoding used to establish the connection Encoding of the Character_set_database database Character_set_results encoding of the result set Encoding of the Character_set_server database server As long as the guarantee system adopts the same encoding method, it can

It is important to avoid potential data type conversions as much as possible.If you compare character data with numeric data, Oracle automatically converts the character type with the To_number () function, which results in a full table scan.Example 2: Column col1 in table Tab1 is a character type (char), the following statement has a type conversion:Should be written as:Oracle Performance optimization Operation two:

Original address: HTTP://WWW.CSDN.NET/ARTICLE/2015-09-18/2825737/3Reduce the memory footprint of an objectThe first step to avoiding oom is to try to minimize the amount of memory that is allocated to new objects and use lighter objects as much as possible.1) Use more lightweight data structuresFor example, we might consider using traditional data structures such as Arraymap/sparsearray instead of HashMap. Figure 8 illustrates how HashMap works, and, in most cases, shows inefficiencies and memor

Background: Coding issues have been plagued by program developers, especially in Java, because Java is a cross-platform language that switches between encodings on different platforms. Next, we will introduce the root causes of Java coding problems, the different encoding formats commonly encountered in Java, the scenarios where coding is often required in Java, the causes of Chinese problems, and several places where coding may exist in Java WEB development; How an HTTP request controls the enc

When we write the foreground page, we may often use the "javascript+ data" method of generating page elements, but when we have to deal with a large amount of data, resulting in the page needs to show too much control, the page response speed will be straight down.We may often go to troubleshoot the cause of the problem, in fact, after troubleshooting the redundant loops and streamlining the number of controls, we found that performance is still not optimistic, so continue to troubleshoot, an ac

encounter such code, so be careful.5. How to change the length parameter and array?The variable-length parameter feature brings a powerful concept that can help developers simplify code. But what is behind the variable-length parameters? Basically, is an array. Public void Calc (int ... myints ){}calc(1,2,3 );The compiler translates the preceding code into something like this:int []ints={1,2,3}; Calc (ints);But here are two points to note:-Beware of air conditioning with a statement, which is e

Before each modification of the MAVEN multi-module project will have to re-execute the MVN install, the install will have to restart the Jetty/tomcat server, is a waste of time, in fact, the code can be modified without the implementation of install, and do not have to restart the application (except to modify the configuration file), Just like modifying the front-end paging file, everything is just a simple configuration in Eclipse: Debug-Configurations, Debug, check box "Resolve Workspace arti

, it also provides a cost advantage for customers who use their services. Compared to the commercial development language, PHP's development costs are low, but this does not mean that its quality is questionable. Work with the right developers to get higher-performance PHP applications.PHP exaggeratedIs that true? You're just kidding. I don't think so, and a lot of developers don't think so.ConclusionThis is not the terminator of all PHP lies. As the PHP language continues to evolve, it becomes

With the continuous updating and upgrading of web design technology, one after another innovation technology ensued. Although in the web design, follow the trend will make their own design seems to have no idea, but there are many design trends are really worth following, such as the current response design, flat design, the poor scrolling. But some designers have complied with some very "dross" of the design trend, listed below in the web design is about to be eliminated trend. 1. Page Jump A

Method One, try to use complex SQL instead of a simple stack of SQL. For the same transaction, a complex SQL completion is more efficient than a bunch of simple SQL finishes. When you have multiple queries, be good at using joins.
