3.2.3修改课程发布
在课程管理服务定义dao：1）创建course_pub表的dao[mw_shl_code=applescript,true]public interface CoursePubRepository extends JpaRepository<CoursePub, String> { }[/mw_shl_code]2) 修改课程发布service[mw_shl_code=applescript,true] //保存CoursePub public CoursePub saveCoursePub(String id, CoursePub coursePub){ if(StringUtils.isNotEmpty(id)){ ExceptionCast.cast(CourseCode.COURSE_PUBLISH_COURSEIDISNULL); } CoursePub coursePubNew = null; Optional coursePubOptional = coursePubRepository.findById(id); if(coursePubOptional.isPresent()){ coursePubNew = coursePubOptional.get(); } if(coursePubNew == null){ coursePubNew = new CoursePub(); } BeanUtils.copyProperties(coursePub,coursePubNew); //设置主键 coursePubNew.setId(id); //更新时间戳为最新时间 coursePub.setTimestamp(new Date()); //发布时间[/mw_shl_code][mw_shl_code=applescript,true] SimpleDateFormat simpleDateFormat = new SimpleDateFormat("YYYY‐MM‐dd HH:mm:ss"); String date = simpleDateFormat.format(new Date()); coursePub.setPubTime(date); coursePubRepository.save(coursePub); return coursePub; } //创建coursePub对象 private CoursePub createCoursePub(String id){ CoursePub coursePub = new CoursePub(); coursePub.setId(id); //基础信息 Optional courseBaseOptional = courseBaseRepository.findById(id); if(courseBaseOptional == null){ CourseBase courseBase = courseBaseOptional.get(); BeanUtils.copyProperties(courseBase, coursePub); } //查询课程图片 Optional picOptional = coursePicRepository.findById(id); if(picOptional.isPresent()){ CoursePic coursePic = picOptional.get(); BeanUtils.copyProperties(coursePic, coursePub); } //课程营销信息 Optional marketOptional = courseMarketRepository.findById(id); if(marketOptional.isPresent()){ CourseMarket courseMarket = marketOptional.get(); BeanUtils.copyProperties(courseMarket, coursePub); } //课程计划 TeachplanNode teachplanNode = teachplanMapper.selectList(id); //将课程计划转成json String teachplanString = JSON.toJSONString(teachplanNode); coursePub.setTeachplan(teachplanString); return coursePub; }[/mw_shl_code]修改课程发布方法，添加调用saveCoursePub方法的代码，添加部分的代码如下：[mw_shl_code=applescript,true]//课程发布 @Transactional public CoursePublishResult publish(String courseId){ .... //创建课程索引 //创建课程索引信息 CoursePub coursePub = createCoursePub(courseId); //向数据库保存课程索引信息 CoursePub newCoursePub = saveCoursePub(courseId, coursePub);if(newCoursePub==null){ //创建课程索引信息失败 ExceptionCast.cast(CourseCode.COURSE_PUBLISH_CREATE_INDEX_ERROR); } .... }[/mw_shl_code] 转载于:https://blog.51cto.com/13517854/2397727
