java - 使用 Camel 过滤文件名时出现错误

Question

我正在尝试使用 apache Camel 对文件名进行过滤。我收到 IllegalArgumentException 类型的错误 - 见下文。你能提供建议吗？

spring xml:

<bean id="adoFilter" class="calypsox.bllInterfaces.cashMgn.cashMgnAdo.AdoFileFilter"/>
                <camelContext xmlns="http://camel.apache.org/schema/spring"
                                id="cashMgn">
                                <propertyPlaceholder id="cashMgnProperty"
                                                location="${bll.resources.env}/cashMgn.properties" />
                                <route id="cashMgnAdo">
                                                <from
                                                                uri="file:{{cashMgnAdoFileDir}}?filter=#adoFilter;move=.org/${date:now:yyyyMMdd}/${file:name}&amp;readLock=changed&amp;readLockCheckInterval=2000&amp;readLockTimeout=10000&amp;moveFailed=.failed" />
                                                <convertBodyTo type="java.lang.String" />
                                                <to uri="bean:cashMgnHandler?method=handleCashMgnAdo" />
                                </route>

                </camelContext>

java过滤器类:

     public class AdoFileFilter<T> implements GenericFileFilter<T> {
                public boolean accept(GenericFile<T> file) {
                                // we want all directories
                                // if (((File) file).isDirectory()) {
                                // return true;
                                // }

                                // we dont accept any files starting with skip in the name
                                return true;// !file.getFileName().startsWith("skip");
                }
}

异常(exception):

Caused by: java.lang.IllegalArgumentException: Could not find a suitable setter for property: filter as there isn't a setter method with same type: java.lang.String nor type conversion possible: No type converter available to convert from type: java.lang.String to the required type: org.apache.camel.component.file.GenericFileFilter with value #adoFilter;move=.org/${date:now:yyyyMMdd}/${file:name}

您必须使用 & 分隔查询参数。在 filter 和 move 参数之间是一个分号。
