Detailed Description
Other advantages and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, which, by way of illustration, is to be read in connection with certain specific embodiments, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the existing configuration management, each configuration item needs to maintain a fixed Key value, and as the business complexity increases, the configuration items are more and more, the management of the configuration items is more and more complicated, and even special records are needed to maintain relevant keys.
And the unified configuration of different scenes can not be flexibly supported by using a mode of matching the universal configuration, and the personalized requirements of different configurations exist in different scenes.
In this regard, as shown in fig. 1, the present invention provides a method for designing a multi-level system configuration service based on a preamble priority matching rule, and a storage method, a configuration matching algorithm and a service interface design for multi-level configuration, which comprise the following steps:
according to the service levels of the configuration items, each level is used as a configuration unit, the name of the level is the name of the configuration unit, and the value of the level is the value of the configuration item of the configuration unit;
storing a Hash value of a configuration path formed by names of a plurality of configuration units as a Key value of the configuration item;
the configuration of the maximum matching degree with the application scene is obtained by adopting a uniform Restful style service interface based on the Http protocol, so that the configuration adaptation of one configuration to multiple scenes is supported, and the situation of multiple configurations of multiple scenes is also supported.
The multi-level system configuration based on the preamble priority matching rule is characterized in that personalized customization is carried out through unified configuration of a personalized system under the condition that codes are not modified, reconstruction and deployment are not carried out on a service system, a module and even a service assembly developed by a user, and the multi-level system configuration comprises modification of multi-level configuration parameters of tenants, application systems, modules, service assemblies and users, so that the multi-tenant personalized requirements on the data, service functions, presentation styles and the like of the service system are met.
The user can customize the business rules according to business requirements and store the related business configuration, but the optimal configuration of quick matching can be very convenient. The system has the advantages that personalized customization is carried out through unified configuration, the flexibility of service system development is improved, the personalized demands of multiple tenants on multiple aspects of the service system are met to the greatest extent, the development efficiency of the service application system is greatly improved, the development period is shortened, and the development cost is saved.
In this embodiment, the multi-level configuration is configured for a configuration path in which one configuration item is composed of a group of configuration units corresponding to a plurality of configuration levels, and the value of the configuration item is arbitrary Json data.
The name (unit) value of the configuration unit includes: tenant (tenant)/application system (app)/module (app_module)/user/component (widget) and supports custom extensions.
The configuration path (routing) consists of a series of ordered key-value pairs of configuration unit names and values, and matches the preamble path entries preferentially.
Each path entry of the configuration path (routing) may use a wildcard "×" to indicate that all values are matched.
The multi-level system configuration service adopts a unified configuration parameter access interface, stores data by using a Redis database, and starts persistence.
The basic design goal of the multi-level system configuration service is for configurations in various scenarios, using the values of the personalized configurations when they exist, and using the values of the generic configurations when there are no personalized configurations.
For example, as shown in fig. 2, the component interface color of one weather environment adopts a blue background (such as background of fig. 2), tenant T1 wants to use a red background (such as background of fig. 2), tenant T1 can configure a personalized configuration for T1, while this configuration only effectively uses the red background for T1, other tenants are not affected by the setting of T1 tenant, tenant T2 does not configure personalized parameters, and when T2 accesses the system, general configuration is adopted to take the blue background.
In this embodiment, the design of the matching algorithm is as follows:
the matching rule of the configuration item adopts a maximum matching degree algorithm under the preamble priority principle, namely the configuration unit which is positioned in front of the configuration path is matched preferentially.
For example: the sequence of each configuration unit of the component (Widget) is as follows: the tense/app/app_module/user/widget, assuming matching conditions are: t1|a1|m1|u1|w1, then the order of their matching possible values is in turn:
·t1|a1|m1|u1|w1
·t1|a1|m1|*|w1
·t1|a1|*|u1|w1
·t1|a1|*|*|w1
·t1|*|m1|u1|w1
·t1|*|m1|*|w1
·t1|*|*|u1|w1
·t1|*|*|*|w1
·*|a1|m1|u1|w1
·*|a1|m1|*|w1
·*|a1|*|u1|w1
·*|a1|*|*|w1
·*|*|m1|u1|w1
·*|*|m1|*|w1
·*|*|*|u1|w1
·*|*|*|*|w1
the number of matches of the maximum matches of the preamble priority longest match recursion algorithm is:
wherein p is the matching frequency of the most matching;
n is the number of configuration units in the configuration path.
In order to improve the search performance, the Key value is formed by adding the Hash value of each value of the configuration path to each name of the configuration path:
Key＝Hash(join(routing*key+,’|’)|unit-type)|join(routing[value],’|’)|unit-type；
the shape is as follows: "95d232ac5fc495f4ced3d6df56096af4|t1|a1|m1|u1|widget.
The multi-level system configuration service interface of this embodiment is designed as follows:
1. setting a configuration item interface:
interface definition: PUT/api/v1/profile/;
request BODY: { type: "configuration item type", routing: [ configuration Path ] };
return value: { code:200, message: "success", data: "Json Format configuration value" };
when setting the configuration, the values of the configuration elements for the generic configuration item are set using the wildcard "×".
The configuration path is composed of a set of Key-Value pairs, such as: { key: "tent", value: "tenant ID" }, { key: "app ID", value: "app ID" }, { key: "app_module", value: "module ID" }, { key: "userid", value: "user ID" };
2. querying a maximum matching degree configuration item interface:
interface definition: POST/api/v1/profile/;
request BODY: { type: "configuration item type", routing: [ configuration path ], data: { Json Format configuration value };
return value: { code:200, message: "success", data: "}.
While the invention has been described in detail in the foregoing general description and specific examples, it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the invention and are intended to be within the scope of the invention as claimed.
