我想使用org.json.simple.JSONObject生成下面的JSON数据对象，如何在java中完成它？

Question

我想跟随使用org.json.simple.JSONObject JSON数据对象，如何在java中做到这一点？

{ 
    friends : [ 
    { 
     name: 'David', 
     interests: 'Cooking', 
    }, 
    { 
     name: 'Charles', 
     interests: 'Hiking', 
    }, 
    { 
     name: 'Mary', 
     interests: 'Football', 
    }, 
    ] 
} 

如果提供了代码snipet，那将非常有帮助！

问候， ABHI

Answer 1

我知道只有一种方式来删除报价：

public class Test { 
public static void main(String[] args) { 
    JSONArray users = new JSONArray(); 
    users.add(new Entry("key1", "val1")); 
    users.add(new Entry("key2", "val2"));   

    System.out.println(users); 
} 

static class Entry implements JSONAware { 
    private String name; 
    private String interests; 

    public Entry(String name, String interests) { 
     this.name = name; 
     this.interests = interests; 
    } 

    public String toJSONString() { 
     StringBuffer sb = new StringBuffer(); 

     sb.append("{"); 

     sb.append(JSONObject.escape("name")); 
     sb.append(":"); 
     sb.append("\"" + JSONObject.escape(name) + "\""); 

     sb.append(","); 

     sb.append(JSONObject.escape("interests")); 
     sb.append(":"); 
     sb.append("\"" + JSONObject.escape(name) + "\""); 

     sb.append("}"); 

     return sb.toString(); 
    } 
} 

}

输出：

[{name:"key1",interests:"key1"},{name:"key2",interests:"key2"}] 

Answer 2

JSONArray arr = new JSONArray(); 

    JSONObject entry = new JSONObject(); 
    entry.put("key1", "value1"); 
    entry.put("key2", "value2"); 

    arr.add(entry); 

    JSONObject json = new JSONObject(); 
    json.put("friends", arr); 

    System.out.println(json.toJSONString()); 

输出：

{"friends":[{"key2":"value2","key1":"value1"}]}
