Jmeter 通过json Extracted 来获取 指定的值的id

import java.lang.String ;
String getTargetName="iphone632g";
//判读相应结果中是否包含指定值：iphone632g
boolean containsCategory=prev.getResponseDataAsString().contains(getTargetName);
vars.putObject("containsCategory",containsCategory);
if(containsCategory){
String [] categoryNameSplit="${categoryName_ALL}".split(",") ;
String [] categoryIDSplit = "${categoryID_ALL}".split(",");
for (int i=0 ; i<categoryNameSplit.length ;i++  ) {
//假如找到指定的分类就将该分类的id put 到变量中去 ;                       
       if (categoryNameSplit[i].equals(getTargetName)) {
           log.info("i=========="+String.valueOf(i));
           log.info("categoryIDSplit["+i+"]="+categoryIDSplit[i]);
           vars.put("categoryId",categoryIDSplit[i]);
           break ;
       }
   }
        }

log.info("${__jexl2(${mobilePhone}*2+4,)}");
int a=${__jexl2(3*2+4,)};
Integer b=${__jexl2(3*2+4,)}+${__jexl2(3*2+4,)};
Integer b1=${__jexl2(${pim_interfaceType}+${pim_interfaceType})};
log.info("b1=="+b1);
//${__jexl2(,)}+${__jexl2(,)} 返回结果可以是String 类型 或者 Integer 类型；
String value ="${__jexl2(3*2+4,)}+${__jexl2(3*2+4,)}" ;
log.info("value="+value);
//String + Integer
String value1 ="${__jexl2(3*2+4,)}"+${__jexl2(3*2+4,)} ;
log.info("value1="+value1);
Integer createOrderAfterlockQty3=Integer.parseInt("1")+${__jexl2(${quantity})};
log.info("xxxxxxxxxxxxxxx=="+createOrderAfterlockQty3);
String concatItemId="\""+"${itemId_all}".replace(",", "\",\"")+"\"" ;
log.info("concatItemId="+concatItemId);
