如何在 "process()" 方法中成功使用 Jackson "ObjectMapper()"
How can I successfully use the Jackson "ObjectMapper()" inside a "process()" method
问题：在 "process()" 方法中使用 Jackson 的 "ObjectMapper()" 会导致异常...
public void process(org.apache.camel.Exchange exchange) throws IOException {
//...this statement causes the exception...
com.fasterxml.jackson.databind.ObjectMapper om = new com.fasterxml.jackson.databind.ObjectMapper();
...
}
异常显示在 Jboss Fuse 控制台中...看起来像这样...

感谢您的帮助！
您遇到的部署错误是因为您在类路径上没有正确版本的 com.fasterxml.jackson.databind jar（定义为 下面)。您是否使用功能文件进行部署？如果是这样，请将其包含在您的问题中。
org.osgi.framework.BundleException: Unresolved constraint in bundle

requirement [585.0] osgi.wiring.package;

您使用 Processor 反序列化为 JSON 的方式是正确的，但是我建议在 Process() 方法之外创建 ObjectMapper()，因为您不需要每次都创建一个新的并且创建一个是昂贵的。
问题：在 "process()" 方法中使用 Jackson 的 "ObjectMapper()" 会导致异常...
public void process(org.apache.camel.Exchange exchange) throws IOException {
//...this statement causes the exception...
com.fasterxml.jackson.databind.ObjectMapper om = new com.fasterxml.jackson.databind.ObjectMapper();

感谢您的帮助！
您遇到的部署错误是因为您在类路径上没有正确版本的 com.fasterxml.jackson.databind jar（定义为 下面)。您是否使用功能文件进行部署？如果是这样，请将其包含在您的问题中。
org.osgi.framework.BundleException: Unresolved constraint in bundle aaa.bbb.ccc.camelRest [585]: Unable to resolve 585.0: missing requirement [585.0] osgi.wiring.package; (&(osgi.wiring.package=com.fasterxml.jackson.databind)(version>=2.7.0)(!(version>=3.0.0)))
您使用 Processor 反序列化为 JSON 的方式是正确的，但是我建议在 Process() 方法之外创建 ObjectMapper()，因为您不需要每次都创建一个新的并且创建一个是昂贵的。
