使用Jackson

Question

当我们使用Jackson和SerializationFeature时

ObjectMapper mapper = new ObjectMapper();
mapper.enable(SerializationConfig.Feature.INDENT_OUTPUT);

以下输出翻译

{"employee1":{"id":"1","firstName":"Ranga","lastName":"Reddy"},"employee2":{"id":"2","firstName":"Raja","lastName":"Reddy"}}

到

{
  "employee1" : {
    "id" : "1",
    "firstName" : "Ranga",
    "lastName" : "Reddy"
  },
  "employee2" : {
    "id" : "2",
    "firstName" : "Raja",
    "lastName" : "Reddy"
  }
}

但我想要这样的输出（属性名称和值之间应该有相同的空格）

{
  "employee1" : {
    "id"        : "1",
    "firstName" : "Ranga",
    "lastName"  : "Reddy"
  },
  "employee2" : {
    "id"        : "2",
    "firstName" : "Raja",
    "lastName"  : "Reddy"
  }
}

输出在上面生成，输出更具可读性。如何实现这个。
