How to resolve this in BeanShell?

Question

I am using this script to update values in JSON file

import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.apache.commons.io.FileUtils;

try {

    String filePath = "blob";
    File file = new File(filePath);
    String jsonContent = FileUtils.readFileToString(file, "UTF-8");


    JSONParser parser = new JSONParser();
    JSONObject jsonObject = (JSONObject) parser.parse(jsonContent);

    String extractedValue1 = vars.get("CASE_TYPE_ID");
    jsonObject.get("caseType").put("id",extractedValue1);
    String extractedValue2 = vars.get("CASE_CONFIG_ID");
    jsonObject.put("caseConfigId", extractedValue2)

    FileUtils.writeStringToFile(file, jsonObject.toJSONString(), "UTF-8");
} catch (Exception e) {
    log.error("Error updating JSON file: " + e.getMessage());
}

When I run the script I got this error:

In file: inline evaluation of: ``import org.json.simple.JSONObject; import org.json.simple.parser.JSONParser; imp . . . '' Encountered "FileUtils" at line 20, column 5.

How to resolve this?

Answer 1

There is a syntax error in your code, line 18 must end with a semicolon.

Apart from this:

1. Since JMeter 3.1 you should be using JSR223 Test Elements and Groovy language for scripting so consider migrating to Groovy. More information: Beanshell vs. JSR223 vs. Java For JMeter: Complete Showdown

2. Groovy has built-in JSON support so you don't need to use 3rd-party libraries. Example code you can use instead:

   def original = new groovy.json.JsonSlurper().parse(new File('blob'))
   original.caseType = vars.get('CASE_TYPE_ID')
   original.caseConfigId = vars.get('CASE_CONFIG_ID')
   
   new File('blob').withWriter { writer ->
       writer << new groovy.json.JsonBuilder(original).toPrettyString()
   }
   

3. If you run your test with > 1 user they will be concurrently writing into the same file (race condition) which will result in data corruption or loss. Consider using different file names or if you cannot - use different folders, one per user.
