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
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; } }
