Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, a kind of dynamic page generates methods of exhibiting, comprises the steps:
Step 1, sets up element template table, element instance table and template instances publishing table in a database;
Step 2, according to showing the display data and pattern data that need to obtain needs displaying from database;
Step 3, carries data object according to business demand assembling, the display data of acquisition and pattern data is put into and carry data object and encapsulate, form the list object carrying data;
Step 4, by the packaged list object back page carrying data for circulation; (as: putting into Request action scope);
Step 5, utilizes mould plate technique to circulate according to the list object carrying data and obtains data and show, realizes dynamic page and generates and show.
Described element template table comprises Element ED field, elementary state field, element name field, element type field and length of element field.Described element instance table comprises template id field, template name field, Element ED field, whether display field and DISPLAY ORDER field.Described template instances publishing table comprises template ID and function code.
Wherein, described mould plate technique adopts JSTL mould plate technique.J2EE is Java 2 Platform Enterprise Edition (Java2Platform, Enterprise Edition), a set of entirely different in the Technical Architecture of traditional application and development, comprise many assemblies, mainly can simplify and the exploitation of Regular application system and deployment, and then raising is portable, safe and use is worth again.JSTL (JSP Standard Tag Library, JSP standard label storehouse) be the JSP tag library of a continuous perfect open source code, JSTL can only operate on the container of support JSP1.2 and Servlet2.3 specification, also supports as standard in JSP 2.0.
The present invention adopts database configuration template table to realize, in database template table configurable often kind of element exhibition method, whether can revise, then page invocation service acquisition data, realize different bandwagon effects according to different configuration parameters in the page.Be specially and take out data from database, sort as required, then collective data is put into Request action scope, utilize label technique ergodic data, circulate by the columns of regulation, export the data of showing, very big minimizing development amount, decreases the maintenance workload of later stage program simultaneously.
As shown in Figure 2, a kind of dynamic page generates display systems, comprises template configuration module 1, data acquisition module 2, list object generation module 3 and page generation module 4; Described template configuration module 1, it is for setting up element template table, element instance table and template instances publishing table in a database; Described data acquisition module 2, it is for needing the display data and the pattern data that obtain needs displaying from database according to displaying; Described list object generation module 3, it is for carrying data object according to business demand assembling, the display data of acquisition and pattern data are put into and carries data object and encapsulate, form the list object carrying data, and by the packaged list object back page carrying data for circulation; Described page generation module 4, it obtains data for utilizing according to the list object carrying data mould plate technique to circulate and shows, realizes dynamic page and generates and show.
Describe the present invention below in conjunction with instantiation.
1. set up a set of displaying element template table TEMPLATE_ATTR_SPEC, show that element shows example table TEMPLATE_INFO, TEMPLATE_DOMAIN template instances publishing table etc.
Wherein TEMPLATE_ATTR_SPEC comprises following core field:
Wherein TEMPLATE_INFO comprises following core field:
Wherein TEMPLATE_DOMAIN comprises following core field:
Field name explanation of field
TEMPLATE_ID template ID
OP_CODE function code
ATTR_TYPE element type comprises (input text box, select drop-down list, textarea multiline text etc.).OP_CODE is the mark defined to each function in actual applications, or as required the permission ID etc. that OP_CODE is revised as each function is also fine.
2. fetch data by displaying demand
This step effect is the ergodic data in order to provide circulation time to the page, according to the template set up in 1.1 data gone out from data base querying can be converted in this step and carry data and pattern data object, put into and carry data object list, after the list object carrying data has obtained, data are returned to the page.
Set up the template class TemplateInfoBo carrying data, roughly code is as follows:
Wherein attrValue is the occurrence that the page will show.
This example is employing the example of Spring, and roughly program is as follows:
Wherein operationList is the set of TemplateInfoBo.
3.JSP page loop-around data
The technology circulations such as similar JSTL can be used to obtain data and carry out data display, a unified displayed page, reduces page development workload.Program is roughly as follows, arranges for every row 3:
Main thought is exactly the set (array etc.) of circulation TemplateInfoBo, according to attributes different in TemplateInfoBo, control to export different page elements, it is such as should how showing of the select drop-down list of html, control whether to show according to isVisible, and follow-up have pure function of showing just can this page multiplexing again, the work being converted to functional configuration data element for this reason that works.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
