1、脚本如下：

import com.fasterxml.jackson.core.JsonProcessingException;

import com.fasterxml.jackson.databind.ObjectMapper;

try {

        String response_data = prev.getResponseDataAsString();

        log.info("response_data: " + response_data);

        ObjectMapper objectMapper = new ObjectMapper();

        Map readValue = objectMapper.readValue(response_data, Map.class);

        String writeValueAsString = objectMapper.writerWithDefaultPrettyPrinter().writeValueAsString(readValue);

        log.info("PrettyFromatJson result: " + writeValueAsString);

        prev.setResponseData(writeValueAsString);

} catch (JsonProcessingException e) {

      log.info("BeanShell PostProcessor failed=======================================", ex);

2、效果如下
