Custom Match Mode

• This paper describes how to customize the extension of org.apache.shenyu.plugin.base.condition.strategy.MatchStrategy.

• Create a new class 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
    }
}

• Add key-value as following in org.apache.shenyu.plugin.base.condition.strategy.MatchStrategy file.

script

${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:

script

custom = org.apache.shenyu.examples.http.strategy.CustomMatchStrategy

• Add enum in org.apache.shenyu.common.enums.MatchModeEnum class:

    /**
     * And custom mode enum.
     */
    CUSTOM(2, "custom"),

• 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;
