如何用嵌套的JSON编写Spring BootYAML配置？

Question

@Component
@ConfigurationProperties
class MyConfig {
  String aaa;
  Foo foo;

  static class Foo {
    String bar;
  }
}

aaa: hello
foo.bar: world

aaa: hello
from:
  {
    "first_initial": "D",
    "last_initial": "E"
  }
foo.bar: world

Answer 1

这应该起作用：

@Component
@ConfigurationProperties
class MyConfig {
  String aaa;
  Foo foo;
  String from;
  static class Foo {
    String bar;
  }
  // ... getters setters

  public JsonObject getFromAsJson() {
    // create object from "this.from"
  }
}

aaa: hello
foo: 
  bar: world
from: |
    {
      "first_initial": "D",
      "last_initial": "E"
    }

还有这个：

aaa: hello
foo: 
  bar: world
from: "{\"first_initial\": \"D\", \"last_initial\": \"E\"}"

第一个版本将保留换行符。
