我想在ui-Grid 3.0中显示' No Data Available ',如果来自ajax的响应包含空的json数据数组ie;

data = {"data": []};

现在,如果我这样做 -

$scope.gridOptions.data = data.data;

'无数据'必须在ui-Grid中出现.

目前发生的是,如果数据为空,用户将获得空白屏幕.

另外如何将其作为默认功能？

在这里查看plunker.

我试图从对话框流程控制台调用我的Rest webhook.我知道部署到任何公共IP是可行的.

但是如何在不将webhook托管到任何公共IP的情况下测试相同的内容,并通过localhost:8080/webhook进行测试？

我扩展了官方Spring-Batch站点 - 批处理服务提供的批处理服务代码, 并修改了ItemWriter以生成CSV并写入数据库.

我使用CompositeItemWriter写入CSV和数据库.但是,JdbcBatchItemWriter与CompositeItemWriter无法正常工作.代码如下所示.

    @Bean
public ItemWriter<Person> writer(DataSource dataSource) {
CompositeItemWriter<Person> cWriter = new CompositeItemWriter<Person>();   

// For DataBase 
JdbcBatchItemWriter<Person> writer = new JdbcBatchItemWriter<Person>();
    writer.setItemSqlParameterSourceProvider(new BeanPropertyItemSqlParameterSourceProvider<Person>());
    writer.setSql("INSERT INTO people (first_name, last_name) VALUES (:firstName, :lastName)");
    writer.setDataSource(dataSource);

// For CSV
FlatFileItemWriter<Person> csvWriter = new FlatFileItemWriter<Person>();
csvWriter.setResource(new FileSystemResource(new File("./csv/new-data.csv")));
csvWriter.setShouldDeleteIfExists(true);
DelimitedLineAggregator<Person> lineAggregator = new DelimitedLineAggregator<Person>();
lineAggregator.setDelimiter(","); 

BeanWrapperFieldExtractor<Person> fieldExtractor = new BeanWrapperFieldExtractor<Person>();
String[] names = {"firstName", "lastName"};
fieldExtractor.setNames(names);
lineAggregator.setFieldExtractor(fieldExtractor);
csvWriter.setLineAggregator(lineAggregator);

List<ItemWriter<? super Person>> mWriter = new ArrayList<ItemWriter<? super Person>>();
mWriter.add(writer); // **Comment this …
