<p>Have you tried using @JsonProperty?</p>

<pre><code>@Entity
public class City {
   @id
   Long id;
   String name;

   @JsonProperty("label")
   public String getName() { return name; }

   public void setName(String name){ this.name = name; }

   @JsonProperty("value")
   public Long getId() { return id; }

   public void setId(Long id){ this.id = id; }
}
</code></pre>


blocks|key|578972|text|请注意，在Jackson+1.x中有org.codehaus.jackson.annotate.JsonProperty，在Jackson+2.x中有com.fasterxml.jackson.annotation.JsonProperty。检查您使用的是哪个ObjectMapper+(来自哪个版本)，并确保使用了正确的注释。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|578973|entityMap^0|I|16|23|19|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

<h2>Jackson</h2>

<p>If you are using Jackson, then you can use the <a href="https://fasterxml.github.io/jackson-annotations/javadoc/2.8/com/fasterxml/jackson/annotation/JsonProperty.html" rel="noreferrer"><code>@JsonProperty</code></a> annotation to customize the name of a given JSON property.</p>

<p>Therefore, you just have to annotate the entity fields with the <code>@JsonProperty</code> annotation and provide a custom JSON property name, like this:</p>

<pre><code>@Entity
public class City {

   @Id
   @JsonProperty("value")
   private Long id;

   @JsonProperty("label")
   private String name;

   //Getters and setters omitted for brevity
}
</code></pre>

<h2>JavaEE or JakartaEE JSON-B</h2>

<p>JSON-B is the standard binding layer for converting Java objects to and from JSON. If you are using JSON-B, then you can override the JSON property name via the <a href="https://javaee.github.io/jsonb-spec/users-guide.html" rel="noreferrer"><code>@JsonbProperty</code></a> annotation:</p>

<pre><code>@Entity
public class City {

   @Id
   @JsonbProperty("value")
   private Long id;

   @JsonbProperty("label")
   private String name;

   //Getters and setters omitted for brevity
}
</code></pre>


<p>I'm using jackson to convert an object of mine to json.
The object has 2 fields:</p>

<pre><code>@Entity
public class City {
   @id
   Long id;
   String name;
   public String getName() { return name; }
   public void setName(String name){ this.name = name; }
   public Long getId() { return id; }
   public void setName(Long id){ this.id = id; }
}
</code></pre>

<p>Since I want to use this with the jQuery auto complete feature I want 'id' to appear as 'value' in the json and 'name' to appear as 'label'. The documentation of jackson is not clear on this and I've tried every annotation that even remotely seems like it does what I need but I can't get <code>name</code> to appear as <code>label</code> and <code>id</code> to appear as <code>value</code> in the json.</p>

<p>Does anyone know how to do this or if this is possible?</p>
