Database Apache数据库配置不支持'；无法使用MapConfiguration

我正在尝试将mapConfiguration（带有属性的文件）与databaseConfiguration结合起来。但是，只能查找文件属性，而不能查找数据库属性。我做错了什么

public class MapConfigProvider extends ConfigurationProvider {
    Map properties = null;
    public MapConfigProvider(Map inProps) {
        super(MapConfiguration.class);
        properties = inProps;
    }

    @Override
    public AbstractConfiguration getConfiguration(ConfigurationDeclaration decl) throws Exception {
        MapConfiguration mapConfig = new MapConfiguration(properties);
        return mapConfig;
  }
}

private静态最终映射属性Map=newhashmap（）；
DefaultConfigurationBuilder=新的DefaultConfigurationBuilder（propFileUrl）；
builder.addConfigurationProvider（“基于文件”，新的MapConfigProvider（propertiesMap））；
builder.addConfigurationProvider（“ctkdatabase”，新数据库配置提供程序（databaseConfigDef））；
CombinedConfiguration combinedConfig=builder.getConfiguration（true）；
String prop1=combinedConfig.getString（“WCM_Web服务_端口”）//从DB中，获取null
String prop2=combinedConfig.getString（“temp”）//从文件中，获取良好的
记录器信息（prop1+prop2）；

我做错了什么？请帮助。

1）在propFileUrl:mainconfig.xml中，我必须指定一个

    <configuration>
  <header>
    <result delimiterParsingDisabled="true" forceReloadCheck="false">
        <nodeCombiner config-class="org.apache.commons.configuration.tree.OverrideCombiner" />
        <expressionEngine config-class="org.apache.commons.configuration.tree.xpath.XPathExpressionEngine" />
    </result>
  </header>

  <system /> <!-- load system properties into config -->

  <properties fileName="common/datasources.properties" />
  <properties fileName="application.properties" />

  <ctkdatabase jndi="jdbc/shaDs" table="TABLE_APPL_PROPERTIES" keyColumn="PROP_NAME" valueColumn="PROP_VALUE"/>

  <!--  load host's config file -->
  <xml fileName="app/cluster/datasources.xml" />
</configuration>

private static final Map<String, Object> propertiesMap= new HashMap<String, Object>();

DefaultConfigurationBuilder builder = new DefaultConfigurationBuilder(propFileUrl);

builder.addConfigurationProvider("filebased", new MapConfigProvider(propertiesMap));

builder.addConfigurationProvider("ctkdatabase", new DatabaseConfigurationProvider(databaseConfigDef));

CombinedConfiguration combinedConfig = builder.getConfiguration(true);

String prop1 = combinedConfig.getString("WCM_WEBSERVICE_PORT");  //From DB, gets null
String prop2 = combinedConfig.getString("temp"); //From file, fetches good
LOGGER.info(prop1 + prop2); 

    <configuration>
  <header>
    <result delimiterParsingDisabled="true" forceReloadCheck="false">
        <nodeCombiner config-class="org.apache.commons.configuration.tree.OverrideCombiner" />
        <expressionEngine config-class="org.apache.commons.configuration.tree.xpath.XPathExpressionEngine" />
    </result>
  </header>

  <system /> <!-- load system properties into config -->

  <properties fileName="common/datasources.properties" />
  <properties fileName="application.properties" />

  <ctkdatabase jndi="jdbc/shaDs" table="TABLE_APPL_PROPERTIES" keyColumn="PROP_NAME" valueColumn="PROP_VALUE"/>

  <!--  load host's config file -->
  <xml fileName="app/cluster/datasources.xml" />
</configuration>

 @Override
 public AbstractConfiguration getConfiguration(ConfigurationDeclaration decl) throws Exception {
   DatabaseConfigDef def = (DatabaseConfigDef)createBean(DatabaseConfigDef.class, decl, null);
   Context env = (Context) new InitialContext().lookup("java:comp/env"); 
   DataSource ds = (DataSource)env.lookup((def.getJndi()));
   return new DatabaseConfiguration(ds, def.getTable(), def.getKeyColumn(), def.getValueColumn());
