接口定义如下：

@Path("get")
public interface StudentApi {

    @GET
    @Path("students")
    List<StudentDetailDto> getStudentList();
}

经过排查，是由于没有指定返回体类型导致的，新增注解指定返回媒体类型,接口顺利返回

@Path("get")
@Produces({MediaType.APPLICATION_JSON})
public interface StudentApi {

    @GET
    @Path("students")
    List<StudentDetailDto> getStudentList();
}
