参照这个瓦片加密全流程，卡在了这个步骤
<keyProvider>：扩展密钥类名。该类名为 jar 包的包路径，例如：com.supermap.model.util.SM4SecretKeyProvider。在实际项目使用中，您需要先将 jar 包编译为 class 文件

这个jar包在哪里呢, 而且并没有找到 classes 路径信息

Answer 1

是扩展密钥编写的项目对应的jar包

如果使用默认的，不进行扩展加密秘钥，我给数据服务进行了加密，在对应前端怎么使用leaflet进行解密呢？
[
    {
        "componentType": "com.supermap.services.components.impl.DataImpl",
        "interfaceType": "com.supermap.services.rest.RestServlet",
        "additions": null,
        "name": "data-OneMap/rest",
        "alias": "data-OneMap",
        "serviceEncryptInfo": {
            "encrptSpec": {
                "keyLength": 128,
                "attributes": null,
                "version": "1.1",
                "algorithm": "SM4"
            },
            "updateTime": "Thu Oct 23 11:31:35 CST 2025",
            "encrptKeyID": "keyID3"
        },
        "url": "http://localhost:8090/iserver/services/data-OneMap/rest",
        "status": "OK"
    }
]
这个是数据服务的加密验证
下面是访问接口的返回
http://localhost:8090/iserver/services/data-OneMap/rest/data/featureResults.json?fromIndex=0&toIndex=19&returnContent=true

这是前端查询部分的代码

        const geometryParam = new L.supermap.GetFeaturesByGeometryParameters({

          datasetNames: datasetNames,

          geometry: circleMarker,

          spatialQueryMode: "INTERSECT",

          returnFeaturesOnly: true,

          maxFeatures: 10

        })

       

        // 执行查询

        const serviceResult = await new L.supermap

          .FeatureService(this.dataUrl)

          .getFeaturesByGeometry(geometryParam)
