在尝试实施"可选实体过滤"时,我遇到了一个问题.我有一个抽象类,如下所示:

   // In your Pom
    <dependency>
        <groupId>org.glassfish.jersey.ext</groupId>
        <artifactId>jersey-entity-filtering</artifactId>
    </dependency>
....

    //Somewhere in resourceConfig: Register entity-filtering selectable feature.
    register(SelectableEntityFilteringFeature.class);
    property(SelectableEntityFilteringFeature.QUERY_PARAM_NAME, "select");

    register(JacksonFeature.class);

... ..

在注册"可选实体过滤"之前一切正常,我测试了很多.

注册"可选实体过滤"后,我有以下错误:
