I want to parse this String to a Jmeter ResultCollector object:

          <ResultCollector guiclass="ViewResultsFullVisualizer" testclass="ResultCollector" testname="View Results Tree" enabled="true">
            <boolProp name="ResultCollector.error_logging">false</boolProp>
            <objProp>
              <name>saveConfig</name>
              <value class="SampleSaveConfiguration">
                <time>true</time>
                <latency>true</latency>
                <timestamp>true</timestamp>
                <success>true</success>
                <label>true</label>
                <code>true</code>
                <message>true</message>
                <threadName>true</threadName>
                <dataType>true</dataType>
                <encoding>false</encoding>
                <assertions>true</assertions>
                <subresults>true</subresults>
                <responseData>false</responseData>
                <samplerData>false</samplerData>
                <xml>false</xml>
                <fieldNames>true</fieldNames>
                <responseHeaders>false</responseHeaders>
                <requestHeaders>false</requestHeaders>
                <responseDataOnError>false</responseDataOnError>
                <saveAssertionResultsFailureMessage>true</saveAssertionResultsFailureMessage>
                <assertionsResultsToSave>0</assertionsResultsToSave>
                <bytes>true</bytes>
                <sentBytes>true</sentBytes>
                <url>true</url>
                <threadCounts>true</threadCounts>
                <idleTime>true</idleTime>
                <connectTime>true</connectTime>
              </value>
            </objProp>
            <stringProp name="filename"></stringProp>
          </ResultCollector>

I do not want to new a ResultCollector, and set many fields, because it takes too much time. Is therer any esasy way to pass the element string, and get according java object.

The easiest way is to ask people in the Internet to do your job for you.

Take a look at SaveService.loadTree() function which reads JMeter's .jmx test plan into a HashTree

Once you load it you should be able to find your ResultsCollector instance from the HashTree

Example code:

package com.example;

import org.apache.jmeter.reporters.ResultCollector;
import org.apache.jmeter.save.SaveService;
import org.apache.jmeter.util.JMeterUtils;
import org.apache.jorphan.collections.HashTree;
import org.apache.jorphan.collections.SearchByClass;

import java.io.File;
import java.io.FileOutputStream;
import java.io.ObjectOutputStream;
import java.util.Collection;

public class JMeterTest {

    public static void main(String[] args) throws Exception {

        JMeterUtils.loadJMeterProperties("c:/apps/jmeter/bin/jmeter.properties");
        JMeterUtils.setJMeterHome("c:/apps/jmeter");

        HashTree testplan = SaveService.loadTree(new File("c:/apps/jmeter/bin/test.jmx"));
        SaveService.loadProperties();

        SearchByClass<ResultCollector> listenerSearch = new SearchByClass<>(ResultCollector.class);
        testplan.traverse(listenerSearch);
        Collection<ResultCollector> listeners = listenerSearch.getSearchResults();
        ResultCollector resultCollector = listeners.stream().findFirst().get();

        FileOutputStream resultCollectorOut = new FileOutputStream("resultcollector.dump");
        ObjectOutputStream objectOut = new ObjectOutputStream(resultCollectorOut);
        objectOut.writeObject(resultCollector);
        objectOut.flush();
        objectOut.close();
        
    }
}

Once you execute the code you will have resultcollector.dump file created in the folder where the project lives.

So the instance of a Results Collector can be created as simple as:

FileInputStream resultCollectorIn = new FileInputStream(new File("resultcollector.dump"));
ObjectInputStream objectIn = new ObjectInputStream(resultCollectorIn);

ResultCollector resultCollector = (ResultCollector)objectIn.readObject();
objectIn.close();
