java 支持json单引号解析

I am trying to do this [see below], and it is throwing error.

1String x="{'candidateId':'k','candEducationId':1,'activitiesSocieties':'Activities for cand1'}";
2ObjectMapper mapper = new ObjectMapper();
3
4try {
5    JsonNode df=mapper.readValue(x,JsonNode.class);
6    int i=0;
7} catch .....

Exception:

1org.codehaus.jackson.JsonParseException: Unexpected character (''' (code 39)): was expecting double-quote to start field name

Solution:

It's not valid JSON, but you can tell Jackson to allow it. Here's how.

1String x = "{'candidateId':'k','candEducationId':1,'activitiesSocieties':'Activities for cand1'}";
2ObjectMapper mapper = new ObjectMapper();
3mapper.configure(JsonParser.Feature.ALLOW_SINGLE_QUOTES, true);
4JsonNode df = mapper.readValue(x, JsonNode.class);
5System.out.println(df.toString());
6// output: {"candidateId":"k","candEducationId":1,"activitiesSocieties":"Activities for cand1"}
