Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for updating a configuration file of an application according to an embodiment of the present invention, where the configuration file of the application is an XML (extensible Markup Language) file, and the method includes:
step S100: acquiring a configuration parameter description file from a deployment directory of an application program, wherein the configuration parameter description file comprises at least one configuration node to be updated and a configuration item to be updated contained in each configuration node to be updated;
in one possible embodiment, the configuration parameter description file is in properties format.
In an implementation manner, the at least one configuration node to be updated includes two types, that is, a common configuration node and a group configuration node, where the common configuration node is a unique configuration node, and the group configuration node is a configuration node containing a plurality of configuration items.
In the configuration parameter description file, the name of a configuration node is composed of three parts, namely a prefix, a node type and a node logical name, and the three parts are distinguished by a decimal point (.), and specific examples are as follows:
common configuration node examples:
ares.node.bus_ar＝//parent[@parentName][1]
group configuration node example:
ares.groups.bus_ar＝//parent[@parentName][1]/members,0,1
wherein the prefix ("ares" in the above example) is used to identify the parameter processing module to which the configuration node belongs, the node type is a normal configuration node (denoted by node in the above example) or a group configuration node (denoted by group in the above example), and the node logical name is a character string defined as a practical name (denoted by "bus _ ar" in the above example) that is helpful for user identification. The value of the common configuration node is an XPath expression (such as "// parent [ @ parentName ] [1 ]" in the above example) for locating the configuration node in the original configuration file of the application program, the value of the grouped configuration node is composed of an XPath expression (such as "// parent [ @ parentName ] [1 ]" in the above example) and several logical names (such as "members, 0, 1" in the above example), the logical names are used for identifying a plurality of configuration items contained in the grouped configuration node, and the two logical names are separated by an english comma.
In the configuration parameter description file, the name of the configuration item is composed of a prefix and several sub-attribute names, and the specific example is as follows:
configuration item examples of common configuration nodes:
ares.node.bus_ar.poolSize＝
ares.node.bus_ar.limit.licenseFile＝
configuration item examples for group configuration nodes:
ares.groups.bus_ar.0.member.no＝
ares.groups.bus_ar.0.member.address＝
ares.groups.bus_ar.0.member.port＝
ares.groups.bus_ar.1.member.no＝
text attribute example:
ares.groups.eventchains.a.chain.text()＝
ares.groups.eventchains.b.chain.text()＝
where the prefix (such as "ares. Among several sub-attribute names (0. member.no.) of configuration items of the configuration nodes in the group (such as "areas. groups. bus _ ar.0. member.no" in the above example), the first sub-attribute name "0" is a logical name of the configuration nodes in the group, the following sub-attribute name "member" is used to identify the sub-configuration nodes, and the last sub-attribute name "no" is used to identify the name of one attribute of the sub-configuration nodes. If one attribute of the child configuration node is a text attribute, the child attribute name is represented by "text ()".
Step S110: determining values corresponding to all configuration items to be updated;
in one implementation, values corresponding to all configuration items to be updated may be obtained from any one or more of an environment variable, an application configuration file, and a configuration center. The multiple values of the same configuration item may be obtained from the preset position, and at this time, the value with the highest priority may be finally obtained according to the priorities of the obtained multiple values. The deployment scenes of the application programs are different, and the preset positions are also different, specifically, the preset positions can be determined by combining the deployment scenes of the application programs, and the values corresponding to all the configuration items to be updated are obtained from the preset positions.
The values corresponding to all the configuration items to be updated may not all be obtained from any one or more of the environment variable, the application configuration file, and the configuration center, and in an implementation manner, for the configuration items to be updated which cannot be obtained from any one or more of the environment variable, the application configuration file, and the configuration center, the default values of the configuration items to be updated may be determined from the configuration parameter description file. The default value is empty.
Step S120: for each configuration node to be updated, determining a target configuration node corresponding to the configuration node to be updated from an original configuration file, and updating a value of a target configuration item contained in the target configuration node to a value corresponding to the configuration item to be updated contained in the configuration node to be updated;
in an implementation manner, determining a target configuration node corresponding to the configuration node to be updated from an original configuration file may be implemented by:
traversing configuration nodes in the original configuration file;
if the configuration node in the original configuration file comprises the configuration node corresponding to the configuration node to be updated, determining that the configuration node is a target configuration node corresponding to the configuration node to be updated;
if the configuration node in the original configuration file does not include the configuration node corresponding to the configuration node to be updated, the configuration node corresponding to the configuration node to be updated is created in the original configuration file, and the created configuration node is determined to be the target configuration node corresponding to the configuration node to be updated.
Step S130: and after the values corresponding to all the configuration items to be updated are updated into the original configuration file, generating an updated configuration file so that the application program is started by adopting the updated configuration file.

By the method, when the application program is deployed, engineering personnel can automatically update the configuration file of the application program only by providing necessary parameter configuration information at the appointed position, so that the possibility of manual modification errors is reduced, and the normal operation of the application program is ensured.
In a preferred embodiment, before the configuration file updating method of the application disclosed in the above embodiment is used to update the original configuration file of the application, the original configuration file may also be obtained from the deployment directory of the application; and backing up the original configuration file to prevent the original configuration information of the application program from being lost.
