使用Jackson顯示JSON Map數據以進行漂亮的打印

Question

當我們將Jackson與SerializationFeature一起使用時

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

以下輸出是翻譯

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

進入

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

但是我想要這樣的輸出（屬性名稱和值之間應該有相同的空間）

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

輸出在上面生成，輸出更具可讀性。 如何實現這一點。

使用以下代碼：-

ObjectMapper mapper = new ObjectMapper();
mapper.enable(SerializationFeature.INDENT_OUTPUT);
