> [JSON string for maps] ToStringBuilder.reflectionToString doesnt render
> nested maps correctly.
> ----------------------------------------------------------------------------------------------
>
> Key: LANG-1543
> URL: https://issues.apache.org/jira/browse/LANG-1543
> Project: Commons Lang
> Issue Type: Bug
> Components: lang.*
> Affects Versions: 3.10
> Reporter: Swaraj Pal
> Priority: Major
>
> Nested Maps are not converted correctly as JSON using
> ToStringBuilder.reflectToString commons-lang3:3.10 . Please find below the
> example to reproduce:-
> Class:
> {code:java}
> public class Student {
> private String name;
> private Map<String, String> education;
> //getters and setters...
> public String toString() {
> return ToStringBuilder.reflectionToString(this,
> ToStringStyle.JSON_STYLE);
> }}
> {code}
>
> Driver test:
> {code:java}
> Student p = new Student();
> p.setName("como");
>
> Map<String, String> educationMap = new HashMap<String, String>();
> educationMap.put("primary", "school");
> educationMap.put("graduation", "B.S.");
>
> p.setEducation(educationMap);
>
> System.out.println(p.toString());
> {code}
> The toString() prints
> {code:java}
> {"education":{graduation=B.S., primary=school},"name":"como"}
> {code}
> but I expect as JSON it should print as below (with proper key,value pairs as
> field names and values)
> {code:java}
> {"education":{"graduation": "B.S.", "primary":"school"},"name":"como"}
> {code}
> Suggested fix:
> I can create a Pull request for this issue handling Maps appending logic.
