JAR用于扩展SIDDHI

Question

我想要扩展siddhi，mi java代码是：

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

我生成了我的JAR，您的位置是C:\wso2\wso2das-3.0.1\repository\components\lib

我可以用siddhi的"swordurl“：

from DSBStream
select fraude:swordurl('www.babas.com') as porcsword
insert into testswordphish;

但是我运行了我的执行计划，我得到了下一个错误：

java.lang.NoClassDefFoundError: javax/ws/rs/client/ClientBuilder

这个错误总是发生在我对Siddhi使用外部依赖项时。为什么？

在本例中，我使用下一个外部依赖项：

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;

Answer 1

我将外部jar复制到：

<DAS_HOME>\repository\components\lib
<DAS_HOME>\repository\components\plugins

我也创建了我的jar，包括外部jar。我使用的选项是"Runnable JAR File“。

我的问题依然存在。

我真的不能用外部库扩展Siddhi，也不明白为什么。

我的MANIFEST.MF是下一个：

Manifest-Version: 1.0
Rsrc-Class-Path: ./ siddhi-query-api_3.0.4.jar javax.json-1.0.4.jar ja
 vax.json-api-1.0.jar jaxrs-api-3.0.2.Final.jar resteasy-client-3.0.2.
 Final.jar resteasy-jaxrs-3.0.2.Final.jar siddhi-core_3.0.4.jar
Class-Path: .
Rsrc-Main-Class: org.wso2.siddhi.extension.fraude.Swordphish
Main-Class: org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader
