odata4j - 使用 odata4j 连接到 odata 提供程序的步骤

Question

我尝试使用 odata 服务，但在尝试获取实体时遇到错误。

字符串 serviceUrl = " http://services.odata.org/(S(mvnfyllpw41mbzvkme0o0zug))/ODataOData.svc/ ";

ODataConsumer consumer = ODataConsumers.create(serviceUrl);

// list category names
for (OEntity category : consumer.getEntities("Categories").execute()) {
  String categoryName = category.getProperty("Name", String.class).getValue();
  System.out.println("Category name: " + categoryName);
}
