Question

我正在使用WSO2 Developer Studio 3.5。我在synapse-config项目中开发了一系列配置工件。

然后我开发了自己的自定义类中介。

最终我创建了一个复合应用程序项目。在它的pom中，我选择了配置项目和类中介。

使用mvn clean install命令创建了CAR存档。

我进入了管理控制台，我通过碳应用部分添加了汽车文件。看看我的wso2 esb 4.8.1日志，我看到了一些例外情况：

实际上似乎没有加载类调解器。我尝试了不同的时间，但我总是得到相同的结果。当我尝试添加类中介时，通过单击代理设计视图上的加载类按钮来确认此结果：“路径中找不到类”。手动复制到components / lib文件夹是将自定义类中介添加到我的wso2 esb的唯一方法吗？

Answer 1

中介类应打包在jar文件中，并放在<installdir>/repository/components/lib的服务器上。

此外，您的错误表示汽车文件的部署错误。您是先从管理控制台取消部署还是重新部署？或者从Developer Studio部署？

Answer 2

创建一个中介项目，在里面写下你自己的自定义类。从ur mediator项目的pom.xml创建存档并将其放入其中 /存储库/组件/ lib中

接下来在您的CAR项目中，通过添加ur mediator项目的依赖关系来更改POM，然后最终创建汽车文件。

通过CAR归档部署类介体和工件
