Spring读取配置文件「建议收藏」

说明：

通常情况下，项目将有读取配置文件的需求，可以用于property文件、xml文件等。这里使用spring该对象特征可被读取，写读属性样本。

demo两个属性表明经常使用的物品首先，key 、value关系的map对象（类似property文件）、列表对象list

java对象

import java.util.List;
import java.util.Map;

import org.springframework.stereotype.Repository;

@Repository
public class SystemConfig {
    
    private Map valueMap;
    private List userids;
    

    public List getUserids() {
		return userids;
	}

	public void setUserids(List userids) {
		this.userids = userids;
	}

	public Map getValueMap() {
        return valueMap;
    }

    public void setValueMap(Map valueMap) {
        this.valueMap = valueMap;
    }
    
    public Object getValue(String key){
        if (this.getValueMap().containsKey(key)){
            return this.getValueMap().get(key);
        }else{
            return "";
        }
    }
    
    private List searchConfigList;

    public List getSearchConfigList() {
        return searchConfigList;
    }

    public void setSearchConfigList(List searchConfigList) {
        this.searchConfigList = searchConfigList;
    }

    private Map sendRangeConfig;

    public Map getSendRangeConfig() {
        return sendRangeConfig;
    }

    public void setSendRangeConfig(Map sendRangeConfig) {
        this.sendRangeConfig = sendRangeConfig;
    }
            
    private List syncUserConfigList;

    public List getSyncUserConfigList() {
        return syncUserConfigList;
    }

    public void setSyncUserConfigList(List syncUserConfigList) {
        this.syncUserConfigList = syncUserConfigList;
    }
    
}
