very powerful words, That must not stand the problem of the system's lag. What is the reason?The reason is that the PHP version does not generate a pure static HTML page plug-in, according to the Zlbog developer's reply is "technically difficult to implement", probably because the system is lightweight, so in this regard does not take into account the problem of generating static files, just do pseudo-static processing and design.ZBLOG PHP version of

In the previous blog, mention was made of a note @generatedvalue, which is used to annotate a policy that generates a primary key, one of which is the table.
Note: This method is not commonly used and is only used when encountering special business requirements.
For annotations, refer to the JPA Learning notes (3)--JPA note How to use the table policy to generate primary keys
With this strategy, you need to create a table

How to generate a dynamic link library, i.e.. So file, under Linux.
OneFirst you need a good compilation tool, compiling directly with the GCC command line is no longer a smart idea, a good environment with a compilation tool is important, I chose Easyeclipse, it integrates the CDT, and can easily write C and C + + programs, which automatically integrates the GCC compiler, Compile the work as long as the compilation of the option to point to compile,
meters, by default, will automatically generate labels The label is a point of the file, and the position of each point is the center of its corresponding cell, this file will be placed in the same path as the target file with the filename of the target file plus the suffix "_labels", but I didn't think of anything to do with it. If you want to generate a polygon file from a generated line file, You must a

Using a self-added primary key ID is certainly the best fit when using only a single database. But in the cluster, master-slave architecture, there will be some problems, such as: primary key globally unique.
A scenario for creating a primary key in a clustered environment other than a self-increasing ID
