我想扩展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,你的位置是C:\ wso2 \ wso2das-3.0.1 \ repository \ components \ lib
我可以使用siddhi的“swordurl”:
from DSBStream
select fraude:swordurl('www.babas.com') as porcsword
insert into testswordphish;
但我运行我的执行计划,我得到了下一个错误:
java.lang.NoClassDefFoundError: javax/ws/rs/client/ClientBuilder
this error always happens when I use external dependencies to Siddhi. 为什么?
在这种情况下,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;

您必须将所有依赖项JAR添加到
<DAS_HOME>\repository\components\lib
目录 . 我看到你正在使用JAX-RS库,你也必须添加JAR .我将外部jar复制到:
我也创造了我的 jar ,包括外部 jar . 我正在使用选项“Runnable JAR File” .
我的问题仍然存在 .
我无法用外部库扩展Siddhi并且不明白为什么 .
我的MANIFEST.MF是下一个:
