骆驼 Restlet 不能在罐子里工作

Question

我正在使用 Camel 2.16.2。我正在使用 camel restlet（camel-restlet 版本 2.16.2）来定义我的 Web 服务。

restConfiguration().component("restlet")
            .dataFormatProperty("prettyPrint", "true")
           .host(propertiesConfig.getString("localhost"))
            .port("8568");

并定义了一个网络服务：

rest("/")
    .post("/myService")
    .consumes("application/json")
    .to("direct:myServiceRoute");

我正在使用 maven-assembly-plugin 构建一个包含所有依赖项的 jar。运行在 IDE 上顺利运行（我使用的是 intellij），但是每当我使用 jar 启动应用程序时（通过执行 java -jar），我都会遇到异常：

Exception in thread "main" org.apache.camel.ResolveEndpointFailedException: Failed to resolve endpoint: restlet://http://127.0.0.1:8568/myService?restletMethod=POST due to: Could not find a suitable setter for property: restletMethod as there isn't a setter method with same type: java.lang.String nor type conversion possible: No type converter available to convert from type: java.lang.String to the required type: org.restlet.data.Method with value POST

编辑：/org/apache/camel/component/restlet/ 及其类（包括 RestletConverter 存在于罐子中。

按照@Claus Ibsen 的建议，我将 pom 中的程序集插件代码替换为：

成功了..:)
