Compressed package is uploaded onto the server, and server is put into offer by tender XML file in parsing queue again, then the multithreading by servicing
The parsing of offer by tender XML file is carried out, the parsing data for importing offer by tender XML file are saved in database.
Preferably, the method for the present invention parses XML file using Xstream.The present invention using Xstream come into
Row executes XML file parsing, and Xstream significantly promotes calculating speed using newest figure card technique, and speed even can
To compare favourably with MPI distributed computing.In addition, Xstream is a kind of OXMapping technology, it is for handling XML file sequence
The frame of change is serialized by javaBean, or when by XML file unserializing, does not need other assisted class and mapping text
Part, so that XML serialization is no longer cumbersome.
XStream is explored using structure of the Java reflection mechanism to the object tree to be serialized at runtime,
It does not need to modify object.XStream can serialize inside field, including private private and final field, and
And support non-public class and inner classes.
Under default condition, XStream does not need configuration mapping relations, and object and field will be mapped as XML element of the same name.
But when the masurium difference in object and field name and XML, XStream supports specified alias.XStream is supported in method
The mode of mode or the Java mark of calling specifies alias.
XStream uses the type transducer of system default when carrying out data type conversion.Meanwhile also supporting user
Customized type transducer.
Specifically, being parsed using Xstream to bill of quantities XML file；When bill of quantities XML file solution
After analysis, Spring JDBC is called to save the parsing data to data library of bill of quantities XML file.
Bid contrul valence list XML file is parsed using Xstream；It is tied when bid contrul valence list XML file parses
Shu Hou calls Spring JDBC to save the parsing data to data library of bid contrul valence XML file.
Offer by tender XML file is parsed using Xstream；After the parsing of offer by tender XML file, call
Spring JDBC saves the resolution file of offer by tender XML file to database.
The present invention carries out data storage using Spring JDBC in storage mass data.
Spring JDBC is the Persistence Layer Framework that spring official provides, and is abstracted and has been encapsulated to JDBC, disappeared
In addition to the code of the JDBC repeatability of repeated and redundant, operating database is made to become simpler.
Spring JDBC itself is not an ORM frame, compared with hibernate, its not no so cumbersome,
The update for carrying out big data quantity saves in aspect, substantially increases performance and execution efficiency.
Further, in the method for the present invention, multithreading is managed using java thread pond, uses new Fixed Thread
Pool creates a fixed length thread pool, controls thread maximum number of concurrent, and the thread exceeded can wait in the queue.Further,
It adopts
It is managed also to be included in multithreading in multithreading with java thread pond and obstruction queue Blocking Queue is added.
Block queue Blocking Queue, is a queue first；Under multi-thread environment, so-called obstruction refers to
Thread can be hung up in some cases, once condition meets, the thread being suspended can be waken up automatically again.Each programmer is necessary
These details oneself are controlled, efficiency and thread-safe are especially also taken into account.Obstruction queue is usually used in the field of producers and consumers
Scape, producer thread can be stored to production result in obstruction queue, and consumer thread takes out intermediate result and in the future
Modify them.Block queue meeting autobalance load to consume if producer thread collection runs slower than consumer thread's collection
Person's thread collection will block when waiting result；If producer thread collection runs fastly, it will wait consumer thread
Collection is caught up with.
The present invention is added obstruction queue Blocking Queue, Blocking Queue and has well solved in multithreading,
How highly effective and safe " transmission " data the problem of, programmer without be concerned about when need block or wake up thread.Pass through
These efficient and thread-safe queue classes, bring great convenience for the multithread programs of fast construction high quality.
The present invention uses member Array Blocking Queue, the Array Blocking of Blocking Queue
Queue is one and blocks queue with the bounded that array is realized, this queue carries out element according to the principle of first in first out (FIFO)
Sequence.Support fair lock and non-fair lock.Advantage is the working efficiency greatly improved, reduces creation and time of destroying threads
Number, each worker thread can be recycled, and multiple tasks can be performed.Line can be adjusted according to the ability to bear of system
The number of Cheng Chizhong active line thread prevents from excessively increasing server load because consuming excessive memory.
Further, the software and hardware information inspection is the check item selected according to the page, and on backstage, real-time perfoming is initial
Change and check list, then form a combination of current strategies by ornamenter, is finally combined according to this and execute software and hardware information
It checks.
Further, it is first to configure service fee norm in database, according to each that the comparison of one key of the execution, which automaticly inspects,
The service fee norm of project takes out corresponding strategy, carries out initialization and checks list, then forms the one of current strategies by ornamenter
A combination finally executes key comparison according to the combination of current strategies and automaticly inspects.
Further, the comparison of one key of execution, which automaticly inspects, follows primary access evidence, first use data, a storing data
Principle, specifically comprising as follows:
The first step, the comparison that first needs are used check data, all come out from data base querying, one will be carried out by being encapsulated into
Key compares inside the data object automaticly inspected；
Second step, the key comparison for then calling above-mentioned design pattern packaged automaticly inspect processor System Auto
Inspect Processor compares the data object automaticly inspected using the key that carry out packaged in the first step, is examined
It looks into；
Inspection result is carried out database script encapsulation by third step, then calls Spring JDBC, and disposable batch is protected
It is stored in database.
Execute a key compare automaticly inspect follow primary access evidence, first use data, storing data principle it is excellent
Point:
A. avoid side using data, data, Bian Baocun data are inquired in side, in this way can be significantly if three are carrying out simultaneously
It influences performance and reduces to check speed；
B. a possibility that causing deadlock is substantially reduced；
C. code logic orderliness is apparent from understandable；
D. it is easy to later maintenance work；
Further, the data that XML has been parsed are separated with the data of inspection result.The data parsed due to XML
It measures too big, if updating inspection result to causing to be updated in former table, greatly reduces renewal speed, and cause deadlock
Probability geometry rises.So being separated with meter reading with table is write, inspection result is stored in new table, this table is only responsible for writing number
According to since the data volume of inspection result will be far smaller than the data volume after XML parsing, so substantially increasing concurrency performance and effect
Rate also reduces the probability for causing deadlock.
In the method for the present invention, the inspection of software and hardware information is executed, is the check item selected according to the page, in backstage real-time perfoming
