Java Spring缓存，save所有对更新的正确处理 [英] Java spring caching, saveAll proper handling of update

问题描述

因此，我目前尝试在我的Spring Boot应用程序中尽可能多地安全进行缓存.

So I currently try to cache as much as possible SAFELY in my spring boot application.

伙计，我碰到了脑部刮擦. 我该如何处理saveAll(实体列表)方法?

Bud i run into brain scratcher. How do i handle saveAll(list of entities) method ?

 public List<WorkaroundEntity> saveAll(List<WorkaroundEntity> workaroundEntities) {

此方法保存所有实体，我当前的缓存如下:

This method saves all entities, My current cache looks like this :

  /**
    * K=WorkaroundEntity.id   --   Value=WorkaroundEntity
   */
   private static final String CACHE_NAME_WORKAROUNDS = "workarounds";

因此，基本上我的地图具有ID和实体. 用户保存所有实体的列表时.从我的角度来看，我只有这个选项:

So basically my map has IDs AND entities. When user saves LIST OF ALL ENTITIES. From my point of view I only have this option :

@CacheEvict(value = CACHE_NAME_WORKAROUNDS, allEntries = true, condition = "#workaroundEntities.size()>=1")
public List<WorkaroundEntity> saveAll(List<WorkaroundEntity> workaroundEntities) {
    return workaroundEntityRepository.saveAll(workaroundEntities);
}

我错了吗，对于这种问题有更好的解决方案吗?

到目前为止，我在方法中使用此缓存:

So far i use this cache in methods :

public WorkaroundEntity save(WorkaroundEntity workaroundEntity)
public WorkaroundEntity findById(long id)
public void delete(WorkaroundEntity workaroundEntity) 
public WorkaroundEntity getOne(long id) 

您如何处理适用于集合而不是单个实体的方法?

推荐答案

最后，对我来说，答案是一起使用hibernate 2级缓存和spring缓存.我两个字都很好.除此之外，我还创建了一个附加的内部缓存，以减少对数据库的访问.

In the end , answer for me was to use hibernate 2nd level cache and spring cache together. I got best of both words. In addition to this i have created additiona linternal caches to hit database even less.
