Method for displaying a large number of business objects based on lazy loading technique

Abstract

The invention relates to a method for displaying a large number of business objects based on the lazy loading technique. The method comprises the steps that a server-side Servlet prepares the precondition of a query; a client side transmits request parameters to a server side; the server-side Servlet acquires the parameters and takes measures; the server-side Servlet submits a query request, and a business component queries data, conducts authority verification and returns data; the server-side Servlet receives a returned query result or a result obtained from a cache, conducts format conversion and returns data to the client side; the client side displays the result in a form, a form control judges whether submission continues or the request ends. The method has the advantages that paging display is achieved under the condition with complicated business objects and a large number of data, requirements of a complicated business object application service rule are met, the problem of a traditional method that displaying of data in a form is slow due to large data size is solved, and a user can check data in the shortest possible time.

Description

technical field [0001] The invention relates to a computer communication technology, in particular to a method for displaying a large number of business objects based on slow loading technology. Background technique [0002] There are generally two traditional implementation methods: [0003] 1. Database-based query paging method [0004] The database provides a development interface to support the function of query paging, and provides the start position index and end position index of the query during the data query process, and the database can query the data of the corresponding position range. When displaying a certain page of data in paging, calculate the start position index and end position index required by the database query according to the current page number and the number of displayed items on each page, pass in the start position index and end position index query data, and convert the data into Business objects, display business objects in the table control...

AI Technical Summary

Problems solved by technology

The user experience of this method is slow loading for the first time and fast page turning. When there is a large amount of data and complex business rules, the waiting time for the first display of data is long

[0007] Among the above two methods, although the first method is efficient, there is no way to apply business rules to each piece of data, and there is no way to load complex business attributes

The second method solves the problem of loading complex attributes of business objects and applying business rules, but when loading each page of data, it is necessary to load all the data and apply business rules first. This process is time-consuming, and the waiting time required to display the data Linear relationship with data size

[0008] Chinese patent CN102411585A discloses a webpage paging data preloading method and system, but it cannot meet the needs of complex business object application business rules, and at the same time solve the problem of slow data display in tables caused by the large amount of data existing in traditional methods question

[0009] At present, there is no relevant report on a method to solve the problem of applying business rules while using complex business objects, and at the same time improving the display performance of a large number of complex business objects in tables
