Spring @Value 注入 map 和 list

EL表达式+JSON写法

@Value("#{'${scio.cloud.list}'.split(',')}")
private List<String> list;

@Value("#{${scio.cloud.maps}}")
private Map<String,String> maps;

yml文件

scio.cloud.list: topic1,topic2,topic3
scio.cloud.maps: "{key1: 'value1', key2: 'value2'}"

        this.list = list;
    }

    public void setMaps(Map<String,String> maps) {
