This paper describes how to customize the extension of org.apache.shenyu.plugin.base.condition.strategy.MatchStrategy
.
Create a new project and introduce the following dependencies:
<dependencies> <dependency> <groupId>org.apache.shenyu</groupId> <artifactId>shenyu-plugin-base</artifactId> <version>${project.version}</version> </dependency> </dependencies>
CustomMatchStrategy
, extends org.apache.shenyu.plugin.base.condition.strategy.AbstractMatchStrategy
, implements org.apache.shenyu.plugin.base.condition.strategy.MatchStrategy
, add annotation org.apache.shenyu.spi.Join
./** * This is custom match strategy. */ @Join public class CustomMatchStrategy extends AbstractMatchStrategy implements MatchStrategy { @Override public Boolean match(final List<ConditionData> conditionDataList, final ServerWebExchange exchange) { // custom match strategy } }
org.apache.shenyu.plugin.base.condition.strategy.MatchStrategy
file.${spi name} = ${custom class path}
${spi name}
represents the name of spi
and ${custom class path}
represents the fully qualified name of the class. Such as:
custom = xxx.xxx.xxx.CustomMatchStrategy
Package the project and copy it to the lib
or ext-lib
directory of the gateway (bootstrap-bin).
In the Apache ShenYu
gateway management system --> BasicConfig --> Dictionary, find the dictionary code as MATCH_MODE
, add a new piece of data, pay attention to the dictionary name: ${spi name}
.
DictionaryType:
matchMode
;DictionaryCode:
MATCH_MODE
;DictionaryName:
${spi name}
, input your custom spi name;DictionaryValue: When used, the value of the drop-down box, do not repeat with the existing;
DictionaryDescribe: desc your custom match strategy;
Sort: to sort;
Status: open or close.
