我正在使用Camel路径来分割zip文件,并使用以下代码处理它:

return rb -> rb.from("file:{{inbox}}?recursive=true&readLock=markerFile&delay=5000&antInclude=**/*.zip&move=.done")
            .routeId("Unzip_File_Route")
            .split(new ZipSplitter())
            .streaming()
                .process(new MyFileProcessor())
            .to("file:{{inbox}}?fileName=${header.unzippedPath}")
            .end()
            ;

并且我正在使用一个zip文件来测试它,但是我得到了以下异常:

我正在使用Debian来运行这段代码。谢谢

问题出在其他地方。此处ZipSplitter中获得的流未关闭,而是由于缺少TypeConverter而从一开始就为空。
添加以下插件将这些转换器添加到jar中,并解决了我的问题:

<plugin>
                <groupId>org.apache.camel</groupId>
                <artifactId>camel-maven-plugin</artifactId>
                <version>${version.camel}</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>prepare-fatjar</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
