我正在将一个Spring项目与Mule和a集成，在启动时收到以下错误。有没有最好的参考资料可以用于弹簧骡子与全流量的整合？

Jeba，我有一个符合您要求的模板：
https://github.com/jrichardsz/mule-esb-usefull-templates
这个项目包含一个简单的弹簧组件，并展示了如何在mule app中使用它。
还显示如何读取属性文件并同时处理mule消息。

我希望这会对你有所帮助。
问候。
答案 1 :(得分：0)
根据documentation，spring-object允许的唯一子元素是属性和属性。如果要配置property-entry-point-resolver，则需要为组件执行此操作。
答案 2 :(得分：0)
试试下面的内容
<component>
<property-entry-point-resolver property = "checkEvent" />
</component>
