我找到了解决这个问题的替代方案。我不完全使用 OData 库。我创建了发布请求的方法。
public void insertData(String entityName, Entity entity)
{
try {
ResWrap<Entity> resW = new ResWrap<Entity>(new URI(this.baseURI.concat("/").concat(entityName)), "full", entity);
ClientEntity clientEntity = this.client.getBinder().getODataEntity(resW);
//String message = getMessageRebuild(client.getWriter().writeEntity(clientEntity, ContentType.APPLICATION_JSON));
InputStream is = client.getWriter().writeEntity(clientEntity, ContentType.APPLICATION_JSON);
if(is != null)
{
System.out.println("POST: "+post(this.baseURI.concat("/").concat(entityName), is));
//System.out.println("POST:"+post("http://localhost:8888/"+entityName, is));
}
} catch (URISyntaxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ODataSerializerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public String post(String url,InputStream message) throws Exception{
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(url);
//post.addHeader("Content-Type", "application/json;odata.metadata=minimal");
//post.addHeader("Accept", "application/json;odata=verbose");
post.addHeader("Content-Type", "application/json");
post.addHeader("Accept", "application/json");
HttpEntity entity = new ByteArrayEntity(IOUtils.toByteArray(message));
post.setEntity(entity);
HttpResponse response = client.execute(post);
String result = EntityUtils.toString(response.getEntity());
return result;
}
insertData 取两个参数:我生成的 entityName + Entity。我使用库 org.apache.http 将 http 消息发送到 OData 服务器。
