某些字段的Jackson JSON自定义序列化

您可以实现自定义序列化器，如下所示：

public class Person {    public String name;    public int age;    @JsonSerialize(using = IntToStringSerializer.class, as=String.class)    public int favoriteNumber:}public class IntToStringSerializer extends JsonSerializer<Integer> {    @Override    public void serialize(Integer tmpInt,     JsonGenerator jsonGenerator,     SerializerProvider serializerProvider)     throws IOException, JsonProcessingException {        jsonGenerator.writeObject(tmpInt.toString());    }}

Java应该为您处理自动装箱从

int

Integer
