这是关于JPA瞬态注释的以下问题的后续操作 为什么JPA有@Transient注释？

我有一个我不想持久的瞬态变量,它标有瞬态注释.但是,当我想从我的其余控制器生成JSON时,此瞬态变量在输出的JSON中不可用.

POJO PublicationVO是直接的,没有花哨的属性,只有一些私有属性(持久化)有getter和setter以及1个瞬态变量.

@RequestMapping(value = { "{publicationId}"}, method = RequestMethod.GET, produces = "application/json")
@ResponseBody public PublicationVO getPublicationDetailsJSON(@PathVariable(value = "publicationId") Integer publicationId) {
    LOG.info("Entered getPublicationDetailsJSON - publicationId: " + publicationId);

    //Call method to get the publicationVO based on publicationId
    PublicationVO publicationVO = publicationServices.getPublicationByIdForRestCalls(publicationId);       
    LOG.info("publicationVO:{}", publicationVO);

    LOG.info("Exiting getPublicationDetailsJSON");
    return publicationVO;
}

PublicationVO如下

    package com.trinity.domain.dao;

import java.util.Calendar;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
