这里有一个resteasy rest API的示例。
xml的一部分：

<dependencies>
   <dependency>
        <groupId>org.glassfish.jersey.containers</groupId>
        <artifactId>jersey-container-grizzly2-http</artifactId>
    </dependency>

    <!-- Jersey DI and core-->
    <dependency>
        <groupId>org.glassfish.jersey.inject</groupId>
        <artifactId>jersey-hk2</artifactId>
    </dependency>
    <dependency>
        <groupId>org.glassfish.hk2</groupId>
        <artifactId>hk2-metadata-generator</artifactId>
        <version>3.0.3</version>
    </dependency>

    <!-- add jackson as json provider -->
    <dependency>
        <groupId>org.glassfish.jersey.media</groupId>
        <artifactId>jersey-media-json-jackson</artifactId>
    </dependency>
    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jackson-provider</artifactId>
        <version>2.3.10.Final</version>
    </dependency>
    <dependency>
        <groupId>org.glassfish.jersey.media</groupId>
        <artifactId>jersey-media-json-jackson</artifactId>
        <version>${jersey.version}</version>
    </dependency>
    <dependency>
        <groupId>org.glassfish.jersey.media</groupId>
        <artifactId>jersey-media-moxy</artifactId>
        <version>${jersey.version}</version>
    </dependency>
    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-client</artifactId>
        <version>3.9.3.Final</version>
    </dependency>
</dependencies>

我的资源类的一部分：

@Path("/test")
@GET
@Produces("application/json")
@Consumes("application/json")
public Date test() {
    return new Date();
}

所以当我请求http://localhost:8080/test时，响应是1685343320152而不是日期格式。
哪里错了？
