ExportingCostCenterInformation

ExportingCostCenterInformation

我正在尝试从Spring REST控制器调用BAPI。
后端系统的调用工作正常,但是返回ResponseEntity会导致错误“此响应已调用getOutputStream()

@RequestMapping( method = RequestMethod.GET )
public ResponseEntity<List<ExportingCostCenterInformation>> getBusinessPartners()
{
    final ErpEndpoint endpoint = new ErpEndpoint(new ErpConfigContext("ErpQueryEndpoint_RFC"));

    final BapiQuery query = new BapiQuery("BAPI_COSTCENTER_GETLIST")
        .withExporting("CONTROLLINGAREA", "KOKRS", "1000");

    List<ExportingCostCenterInformation> ecci = null;
    try {
        ecci = query.execute(endpoint)
            .get("COSTCENTER_LIST")
            .getAsCollection()
            .asList(ExportingCostCenterInformation.class);
    } catch (UnsupportedOperationException | IllegalArgumentException | QuerySerializationException | DestinationNotFoundException | DestinationAccessException | QueryExecutionException e) {
        // ...
    }

    return ResponseEntity.ok(ecci);
}


任何想法为什么会出现此错误?

最佳答案

未正确定义类ExportingCostCenterInformation的getter和setter方法。那就是问题所在。
