ofbiz之服务实体api积累

根据delegator 获取 LocalDispatcher

     LocalDispatcher thisDispatcher = GenericDispatcher.getLocalDispatcher(delegator.getDelegatorName(), delegator);

 

2：根据dispatcher 获取 DispatcherContext

    DispatchContext dctx  =
        dispatcher.getDispatchContext();

 

3:获取一个GenericValue对象的所有字段

   GenericDelegator delegator =  DelegatorFactory.getDelegator("default");   
   GenericValue tmp  = delegator.makeValue("UserLogin");
   String entityName = tmp.getEntityName();
   ModelEntity entity = delegator.getModelEntity(entityName);
   List fieldNameList = entity.getAllFieldNames();

 

4:----

   ServiceDispatcher sd = ServiceDispatcher.getInstance(dispatcherName, delegator)；

    LocalDispatcher dispatcher = sd.getLocalDispatcher(dispatcherName);

    dispatcher = new GenericDispatcher(dispatcherName, delegator, readerURLs, loader, sd);

    DispatchContext dc = new DispatchContext(name, readerURLs, loader, null);

5:ofbiz URL

    URL formFileUrl = FlexibleLocation.resolveLocation(resourceName);

    resourceName:component://common/widget/LookupForms.xml

    formFileUrl:file:/E:/workspace/cpsp20110819/framework/common/widget/LookupForms.xml

 

 

 Set<String> groupNames = getModelGroupReader().getGroupNames(delegatorBaseName);
        for (String groupName: groupNames) {
            GenericHelperInfo helperInfo = this.getGroupHelperInfo(groupName);
            String helperBaseName = helperInfo.getHelperBaseName();

            if (Debug.infoOn()) Debug.logInfo("Delegator \"" + delegatorFullName + "\" initializing helper \"" +
                    helperBaseName + "\" for entity group \"" + groupName + "\".", module);
            if (UtilValidate.isNotEmpty(helperInfo.getHelperFullName())) {
                // pre-load field type defs, the return value is ignored
                ModelFieldTypeReader.getModelFieldTypeReader(helperBaseName);
                // get the helper and if configured, do the datasource check
                GenericHelper helper = GenericHelperFactory.getHelper(helperInfo);

                DatasourceInfo datasourceInfo = EntityConfigUtil.getDatasourceInfo(helperBaseName);
                if (datasourceInfo.checkOnStart) {
                    if (Debug.infoOn()) Debug.logInfo("Doing database check as requested in entityengine.xml with addMissing=" + datasourceInfo.addMissingOnStart, module);
                    try {
                        helper.checkDataSource(this.getModelEntityMapByGroup(groupName), null, datasourceInfo.addMissingOnStart);
                    } catch (GenericEntityException e) {
                        Debug.logWarning(e, e.getMessage(), module);
                    }
                }
            }
        }

6： 获取所有实体名称

    Set<String> entitys = delegator.getModelReader().getEntityNames();
    entityArr =  delegator.getModelReader().getEntityNames().toArray(new String[entitys.size()]);

7：清除实体缓存

    Cache entityCache = delegator.getCache();

    entityCache.remove(entityName);

 

8 : xml 中取${}值

        FlexibleStringExpander fse = FlexibleStringExpander.getInstance(expression);
        return fse.expandString(context, timeZone, locale);

 

9: xml 获取多个 不同节点

        Set<String> nameSet = UtilMisc.toSet("set", "action","log");
        for (Element actionOrSetElementOrLog : UtilXml.childElementList(eca, nameSet)) {

 

10 : String 类型xml  与 Map 互相转换

        XmlSerializer.deserialize

        XmlSerializer.serialize

11:类型转化类的加载

Iterator<ConverterLoader> converterLoaders = ServiceLoader.load(ConverterLoader.class, loader).iterator();
