spring boot项目初始化，字典加载到内存中

1.项目初始化把常用的字典存到到内存中，

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import javax.annotation.PostConstruct;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

@Component
public class CacheUtils {
    //存储字典code和name的值
    public static Map<String, String> facilityTypeMap = new HashMap<String, String>();
 
         
            @Autowired
            private FacilityTypeMapper facilityTypeMapper;       

    @PostConstruct
    public void init() {
        //查询字典的数据
        List<FacilityTypeDO> facilityTypeDOS = facilityTypeMapper.selectList(null);
        //封装到map里
        facilityTypeDOS.forEach(item->{
            facilityTypeMap.put(item.getCode(),item.getName());
        });
        }
   
}
2.调用
public static void main(String[] args) {
//根据code获取对应的name
        CacheUtils.facilityTypeMap.get("字典code");
    }
