Question

写法如下，基本是按照范例写的。

        var bufferServiceByDatasets = new SuperMap.REST.BufferAnalystService(sintoonUx.fxUrl);
        var bufferDistance = new SuperMap.REST.BufferDistance({
            value: 10
        });
        var bufferSetting = new SuperMap.REST.BufferSetting({
            endType: SuperMap.REST.BufferEndType.FLAT,
            leftDistance: bufferDistance,
            rightDistance: bufferDistance,
            radiusUnit: SuperMap.REST.Unit.METER,
            semicircleLineSegment: 10,
        });

        var filterParameter = new SuperMap.REST.FilterParameter({
            attributeFilter: "XM0101='20221421082003'"
        });
        var dsBufferAnalystParameters = new SuperMap.REST.DatasetBufferAnalystParameters({
            dataset: "GHXML_SDBK@mapdata",
            filterQueryParameter: filterParameter,
            bufferSetting: bufferSetting
        });
        bufferServiceByDatasets.events.on({
            "processCompleted": sintoonUx.bufferAnalystCompleted,
            "processFailed": sintoonUx.sqlProcessFailed,
        });
        bufferServiceByDatasets.processAsync(dsBufferAnalystParameters);
 

查看日志的错误信息如下：

08-Oct-2022 17:34:40.493 严重 [http-nio-8090-exec-2] org.glassfish.jersey.server.ServerRuntime$Responder.process Error occurred when processing a response created from an already mapped exception.

请问是啥原因？

您好，您将您的代码替换您的“sintoonUx.fxUrl”放在官网示例中执行是否会报错？如果报错，可以查看network中，缓冲区分析的请求“buffer.jsonp”存在哪种错误。您可以将network页面中报错的缓冲区分析请求的Cookies截图贴在下面。

希望可以给您提供帮助！

我下载了一个  SuperMap iServer 10i(2021) SP1 for Windows(x64) ，在本地部署后，还是报错，

我是在例子的基础上把地图修改为我自己的地图，

classic缓冲区分析可以参考示例：https://iclient.supermap.io/examples/classic/editor.html#analysis_bufferAnalyst。其他各项参数的填写可以查询API文档：https://iclient.supermap.io/web/libs/iclient8c/apidoc/files/SuperMap/REST/SpatialAnalyst/BufferAnalystService-js.html
