如下:启动工程时,加载配置文件的用户名和密码到map中,

通过getKeyByValue()获取即可

 

import java.util.HashMap;
import java.util.Map;
import java.util.Map.Entry;

import javax.annotation.PostConstruct;

import org.apache.commons.lang3.StringUtils;
import org.springframework.stereotype.Component;

@Component
public class PersonalInfoCache {
    
    private static Map<String,String> map = new HashMap<String,String>();
    
    @PostConstruct
    public void initCache() {
        PropertiesLoadUtil propertiesUtil = new PropertiesLoadUtil("commons-config.properties");
        String userName = propertiesUtil.getStringProperty("userName");
        String password = propertiesUtil.getStringProperty("password");
        map.put("userName", userName);
        map.put("password", password);
    }
    
    public  String getKeyByValue(String key){
        if(StringUtils.isEmpty(key)){
            return null;
        }
        for(Entry<String,String> entry:map.entrySet()){
            if(entry.getKey().equals(key)){
                return entry.getValue();
            }
        }
        return null;
    }

}
