Geoserver Mapfish 读取配置文件 config.yaml 时打印错误

Question

我已经在我的服务器中安装了Geoserver 2.8和mapfish打印插件2.8。我已经部署了Geoserver Tomcat 8.0。我遵循了http://docs.geoserver.org/latest/en/user/extensions/printing/

中提到的所有步骤

当我重新启动 tomcat 服务器“printing”文件夹时，其中包含在 Geoserver/data 文件夹下创建的 config.yaml 文件。当我尝试通过提供 url 来验证安装时： http://localhost:8081/geoserver/pdf/info.json

我收到以下错误：

它说读取 config.yaml 文件时出错。找不到 Config.yaml 的错误。

Answer 1

我解决了。问题出在打印插件版本上。我尝试了另一个版本，它成功了。

Answer 2

由于这仍然是当前 geoserver 的 docker 镜像的问题，这就是我解决问题的方法：

下载common-httpclient-3.1.jar

将其复制到 docker 容器中并将其粘贴到 /WEB-INF/lib 文件夹中（例如 /usr/local/tomcat/webapps/geoserver/WEB-INF/lib）。然后重新启动Geoserver。
