Hibernate的一对一,一对多/多对一关联保存的实现

// one to one

private com.rhtcms.cms.entity.main.CustomerMessageContent customerMessageContent; //对应内容表信息

//one to one

private com.rhtcms.cms.entity.main.CustomerMessage customerMessage; //对应客户留言状态表

< id name = "id" type = "string" column = "id" >< generator class = "uuid" /></ id >

< id name = "messageId" type = "string" column = "message_id" >

             < generator class = "foreign" >< param name = "property" >customerMessage</ param ></ generator >

</ id >

< one-to-one name = "customerMessage" class = "CustomerMessage"   constrained = "true"   ></ one-to-one >

CustomerMessage customerMessageSave = mng.save(customerMessage); //保存状态表信息,并获取uuid

CustomerMessageContent customerMessageContent = new CustomerMessageContent();

             //首先对留言,反馈信息进行敏感词过滤

String wordCensor = cmsMng.replaceSensitivity(questionText);

customerMessageContent.setQuestionText(wordCensor); //设置内容表内容

customerMessageContent.setCustomerMessage(customerMessageSave); //设置从表中主表的属性

contentMng.save(customerMessageContent); //同时保存内容表信息

activityMng.save(bean,set);

//......下面是save方法

  bean = dao.save(bean);

// update by 2021年1月23日10:36:56 zqy 优化保存接口

  for (ActivitySign activitySign : set) {

  activitySign.setActivity(bean);

  signDao.save(activitySign);
