SpringBoot配置yml参数 集合类型 报错

定义yml配置中List<Map<String,String>> 类型的参数时，报如下错误。

#产品ROOT类型
product:
  types:
    - name: abc1
      prefix: abc1
      info: abc1
    - name: abc 2
      prefix: abc 2
      nfo: abc2

Binding to target [Bindable@53982634 type = <?>, value = 'provided', annotations = array<Annotation>[[empty]]] failed:

    Property: [0].name
    Value: abc
    Origin: class path resource []:82:13
    Reason: The elements [[0].name,[1].prefix,[2].info] were left unbound.
    Property: [1].prefix

 

public List<Map<String, String>> types;

public void setTypes(List types) {  = types; }

看错误信息，理解跟泛型相关，于是给定义的参数添加 泛型<Map<String,String>>
还是不行，最后发现是set方法才是关键。

public void setTypes(List<Map<String, String>> types) {
     = types;
}
