Spring @Value 注入List和Map

EL表达式+JSON写法

• .java

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

yml常规写法

• .yml

scio:
  cloud
    list: 
      - topic1
      - topic2
      - topic3
scio.cloud.maps[key1]: 'value1'
scio.cloud.maps[key2]: 'value2'

• .java

@EnableConfigurationProperties
@Configuration
@ConfigurationProperties(prefix = "scio.cloud")
publci class ScioCloudConfig{
    
    private List> list;
    
    private Map,String> maps;
    
    public void setList(List> list){
        this.list = list;
    }
    
    public void setMaps(Map,String> maps){
        this.maps = maps;
    }
    
    
}

重点重点

使用了@ConfigurationProperties需要对属性写setter方法。
