说明：

一般项目中都会有读取配置文件的需求，可以使用property文件、xml文件等方式。这里利用spring可读取对象的特性，写了一个读取属性的例子。

demo演示了项目常用的两种属性第一是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;

	public void setUserids(List userids) {

	public Map getValueMap() {
        return valueMap;

    public Object getValue(String key){
        if (this.getValueMap().containsKey(key)){
            return this.getValueMap().get(key);
        }else{
            return "";
        }

    public List getSearchConfigList() {
        return searchConfigList;

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

    public void setSyncUserConfigList(List syncUserConfigList) {
