调用Camel-jackson API时，在操作数堆栈上获取错误类型

时间：2017-01-13 15:07:09

标签： jackson apache-camel osgi jbossfuse blueprint-osgi

我的应用程序和服务器中有camel-jackson和jackson-databind jar，我使用的是jboss fuse。我能够部署没有错误的包，但是当我安装/更新调用camel-jackson api的包时，我得到了下面提到的错误。根据我的要求，我需要两个杰克逊api。

有人可以建议吗？

的pom.xml 

<dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.8.5</version>
</dependency>

对于你的问题不是最理想的答案，因为它没有解决camel-jackson的问题，但我只是通过将我的JsonLibrary切换到GSon（camel-gson）来解决这个完全相同的错误。

https://github.com/apache/camel/blob/master/components/camel-gson/src/main/docs/json-gson-dataformat.adoc

如果您对camel-jackson没有严格要求，这可能对您有所帮助。就像删除camel-jackson一样简单并替换为camel-gson：

的pom.xml：

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-gson</artifactId>
</dependency>

路线建设者：

from("mock:json")
        .bean(genericProcessor())
        .marshal().json(JsonLibrary.Gson) //convert processor result to JSON
