siddhi を拡張したいのですが、mi Java コードは次のとおりです。
package org.wso2.siddhi.extension.fraude;
import org.wso2.siddhi.core.config.ExecutionPlanContext;
import org.wso2.siddhi.core.executor.ExpressionExecutor;
import org.wso2.siddhi.core.executor.function.FunctionExecutor;
import org.wso2.siddhi.query.api.definition.Attribute;
import org.wso2.siddhi.query.api.definition.Attribute.Type;
import javax.json.Json;
import javax.json.JsonReader;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.core.MediaType;
import java.io.StringReader;
public class Swordphish extends FunctionExecutor {
ExpressionExecutor[] url;
public static void main (String[] arg1){
System.out.println("Programa test phishing");
}
@Override
protected void init(ExpressionExecutor[] url, ExecutionPlanContext arg1) {
// TODO Auto-generated method stub
this.url = url;
}
@Override
public Type getReturnType() {
// TODO Auto-generated method stub
return Attribute.Type.FLOAT;
}
@Override
public void start() {
// TODO Auto-generated method stub
}
@Override
public void stop() {
// TODO Auto-generated method stub
}
@Override
public Object[] currentState() {
// TODO Auto-generated method stub
return null;
}
@Override
public void restoreState(Object[] arg0) {
// TODO Auto-generated method stub
}
@Override
protected Object execute(Object[] arg0) {
// TODO Auto-generated method stub
return null;
}
@Override
protected Object execute(Object arg0) {
// TODO Auto-generated method stub
float res = 0;
String e = null;
try {
Client client = ClientBuilder.newClient();
e = client.target("http://52.37.125.225:3000/phishing").queryParam("url", url).request(MediaType.TEXT_HTML)
.get(String.class);
try (JsonReader jr = Json.createReader(new StringReader(e))) {
String valor = jr.readObject().getString("result");
try {
res = Float.parseFloat(valor);
} catch (Exception ex1) {
res = 0;
}
}
} catch (Exception ex) {
ex.printStackTrace();
}
return new Float(res);
}
}

swordurl=org.wso2.siddhi.extension.fraude.Swordphish
JAR を生成しました。場所は C:\wso2\wso2das-3.0.1\repository\components\lib です。
siddhi の「swordurl」を使用できます。
from DSBStream
select fraude:swordurl('www.babas.com') as porcsword
insert into testswordphish;
しかし、実行計画を実行すると、次のエラーが発生します。
java.lang.NoClassDefFoundError: javax/ws/rs/client/ClientBuilder
このエラーは、Siddhi への外部依存関係を使用すると常に発生します。なぜ ？
この場合、次の外部依存関係を使用します。
import javax.json.Json;
import javax.json.JsonReader;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.core.MediaType;
import java.io.StringReader;
