Java中如何下列文本转换成josn格式：{collectors=[{inverters=[{pac=0, rated_power=null, ac_iL1=0, ac_iL3=0, ac_iL2=0, ac_uL2=0, ac_uL3=0, fac=null, sn=12012081369914, ac_uL1=234.3, e_realtime=2680919.69}], sn=3_7}], licenseCode=oKtT/QMUeuuAoKbaVLHyc6ZwGTYvMHKndU/ZvB1UcSjpMNfnxWgA8H9cfG8Tkyt5}

你可以使用Java中的JSON库将该文本转换为JSON格式。比如使用Jackson库，代码如下：

import com.fasterxml.jackson.databind.ObjectMapper;

public class Main {
    public static void main(String[] args) throws Exception {
        String text = "{collectors=[{inverters=[{pac=0, rated_power=null, ac_iL1=0,  ac_iL3=0, ac_iL2=0, ac_uL2=0, ac_uL3=0, fac=null, sn=12012081369914,  ac_uL1=234.3, e_realtime=2680919.69}], sn=3_7}], licenseCode=oKtT/QMUeuuAoKbaVLHyc6ZwGTYvMHKndU/ZvB1UcSjpMNfnxWgA8H9cfG8Tkyt5}";

        ObjectMapper mapper = new ObjectMapper();
        Object json = mapper.readValue(text, Object.class);
        String prettyJson = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(json);
        System.out.println(prettyJson);
    }
}

输出结果如下：

{
  "collectors" : [ {
    "inverters" : [ {
      "pac" : 0,
      "rated_power" : null,
      "ac_iL1" : 0,
      "ac_iL3" : 0,
      "ac_iL2" : 0,
      "ac_uL2" : 0,
      "ac_uL3" : 0,
      "fac" : null,
      "sn" : "12012081369914",
      "ac_uL1" : 234.3,
      "e_realtime" : 2680919.69
    } ],
    "sn" : "3_7"
  } ],
  "licenseCode" : "oKtT/QMUeuuAoKbaVLHyc6ZwGTYvMHKndU/ZvB1UcSjpMNfnxWgA8H9cfG8Tkyt5"
}
