无法实例化提供程序org.geotools.reference.factory.epsg.CartesianAuthor

Question

我正在使用maven shade插件将GeoTools包打包到我的uber Jar:中

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.2.2</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer" />
<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>this.is.my.MainClass</mainClass>
</transformer>
</transformers>
<shadedArtifactAttached>false</shadedArtifactAttached>
<shadedClassifierName>launcher</shadedClassifierName>
</configuration>
</execution>
</executions>
</plugin>

当JAR在docker-compose环境中构建和运行时，该服务可以工作，但当我在Netbeans中运行该服务时，我会遇到几个异常：

等等。

我的pom包含：

正在执行的代码是：

sourceCRS = CRS.decode("EPSG:4326");

编辑：我忘了说我运行的是Fedora 31，运行的是OpenJDK 11。Netbeans被配置为使用OpenJDK 1.8作为默认平台。这可能是由于类加载器引起的问题？

你知道我做错了什么吗？感谢

您需要提供引用代码的实际实现。来自常见问题解答：

问：如何选择EPSG管理机构

引用模块并没有做太多开箱即用的事情——它需要有人告诉它所有有趣的代码的含义(例如"EPSG:4326"(。

您需要在类路径上选择一个EPSG jar；如果你在类路径上有几个EPSG jar，您将获得FactoryException。

对于大多数需求，只需使用gt-epsg-hsql插件：

• gt epsgh hsql：将打开包含官方EPSG数据库到一个临时目录，一个很好的桌面解决方案应用程序

有几种替代方案：

• gt epsg wkt：使用内部属性文件并且是轻量级的而不是官方的和正确的。一个伟大的小程序解决方案

• gt epsg postgres：使用官方epsg数据库，您必须自己加载到PostgreSQL中。Java EE的出色解决方案应用程序。

• gt epsg访问：直接使用官方epsg数据库作为分布式。适用于需要最新版本的windows用户的绝佳解决方案官方数据库。

不支持：

• gt epsg oracle：将官方epsg数据库加载到oracle中使用这个插件

• gt-epsgh-h2：使用这个流行的纯java数据库
