如何在restful中将map转换为json[duplicate]

Question

在我的项目中，我动态生成json，并将其放入map () 中注意：键是动态的，所以我的响应如下所示：

"entry": [
        {
          "key": "student1",
          "value": {
            "name":selva
          }
        },
        {
          "key": "student2",
          "value": {
           "name":"kumar"
          }
        }
       ]

但我预期的反应是：

[
"student1" : {
"name":"kumar"
},
"student2" : {
"name":"selva"
}
]

**My keys are dynamic here...**

如何在泽西取得预期的结果。pom.xml

<!-- Json dependency -->
        <dependency>
            <groupId>org.json</groupId>
            <artifactId>json</artifactId>
        </dependency>
<dependency>
            <groupId>org.glassfish.jersey.media</groupId>
            <artifactId>jersey-media-moxy</artifactId>
        </dependency>

如有任何帮助，我们将不胜感激！！！！
