Spring读取配置文件

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

package eway.flight.utils;

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

import org.springframework.stereotype.Repository;

/**

* @author yzp
*/
@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;
}

}
