骆驼路线测试：找不到适合属性的设置器：

Question

我的下一条路线是带有一个搜索字词的Bean：

from( receiveProtocol+"://"+ipMailServer+"?username="+username+"&password="+password+"&"+options+"&searchTerm=#allowedAddresses")

搜索字词bean就像是垃圾邮件过滤器：仅接受从发件人列表发送的电子邮件：

@Component
public class SpamFilter {

    @Value( "${spring.mailserver.spamfilter}")   String spamFilter; // Contains valid senders separated by comma.   

    @Bean
    public SearchTerm allowedAddresses() {

        String acceptedAddresses[]= spamFilter.split( ",");
        SearchTermBuilder build = new SearchTermBuilder();

        for ( int i= 0; i<acceptedAddresses.length; i++)
            build= build.from( Op.or, acceptedAddresses[ i].trim());

        return build.build();
    }
}

一切都可以与路线和搜索词配合使用。我使用Mockito创建了一个单元测试，当路线中不包含搜索词时，该单元测试可以正常工作。我修改了模拟搜索项的测试，并添加了下一行：

@MockBean(name="allowedAddresses") SpamFilter spamFilter;

但是我得到下一个例外：

org.apache.camel.FailedToCreateRouteException: Failed to create route Email: Route(Email)[[From[imap://localhost?username=info@informer.d... because of Failed to resolve endpoint: imap://localhost?closeFolder=false&consumer.delay=10000&delete=false&disconnect=false&password=informer&peek=true&searchTerm=%23allowedAddresses&unseen=true&username=info%40informer.dispocargo.com due to: Could not find a suitable setter for property: searchTerm 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: javax.mail.search.SearchTerm with value #allowedAddresses

我认为我在测试中缺少模拟某些方法，或者我错了。任何帮助，将不胜感激，谢谢。
