Apache camel 使用Spring DSL的Camel custom@Converter存在问题

我只是想学习自定义转换器，遇到了问题。非常感谢您的帮助。驼峰版本2.17和JBoss Fuse 6.3

@Converter
public class MyConvertor{

    public MyConvertor(){}

    @Converter
    public static String convertTo(Exchange exchange) {}

}

在我的春季DSL中

<convertBodyTo charset="UTF-8" id="_convertBodyTo1" type="com.x.convertor.MyConvertor"/>

错误消息：

 org.apache.camel.InvalidPayloadException: No body available of type: com.x.convertor.MyConvertor but has value: GenericFile[output.txt] of type: org.apache.camel.component.file.GenericFile on: output.txt. Caused by: No type converter available to convert from type: 
        at org.apache.camel.processor.Pipeline.process(Pipeline.java:121)
        at org.apache.camel.processor.Pipeline.process(Pipeline.java:83)
Caused by: org.apache.camel.NoTypeConversionAvailableException: No type converter available to convert from type: org.apache.camel.component.file.GenericFile to the required type: com.x.convertor.MyConvertor

有几个错误。

type

属性应该是您的目标类型（转换后需要的类型）

如果要读取CSV文件的内容以将其转换为POJO，请使用组件。

不走运。更新更改如下。请您帮助转换器公共类MyConvertor{Converter public JSONObject convertTo（GenericFile文件）抛出JSONException，IOException{return JSONObject；}}

 org.apache.camel.InvalidPayloadException: No body available of type: com.x.convertor.MyConvertor but has value: GenericFile[output.txt] of type: org.apache.camel.component.file.GenericFile on: output.txt. Caused by: No type converter available to convert from type:

<convertBodyTo charset="UTF-8" id="_convertBodyTo1" type="java.lang.String"/>

@Converter
public class MyConvertor{

    public MyConvertor(){}

    @Converter
    public static String convertTo(GenericFile body, Exchange exchange) {
        // The exchange parameter is optional
    }

}
