接口定義如下：
@Path("get")
public interface StudentApi {
@GET
@Path("students")
List<StudentDetailDto> getStudentList();
}
經過排查，是由於沒有指定返回體類型導致的，新增註解指定返回媒體類型,接口順利返回
@Path("get")
@Produces({MediaType.APPLICATION_JSON})
public interface StudentApi {
@GET
@Path("students")
List<StudentDetailDto> getStudentList();
}
