我最近开始从一个方法缓存结果.我正在使用@Cacheable和@CachePut来实现所需的功能.

但不知何故,保存操作不会更新findAll方法的缓存.以下是相同的代码段:

@RestController
@RequestMapping(path = "/test/v1")
@CacheConfig(cacheNames = "persons")
public class CacheDemoController {

    @Autowired
    private PersonRepository personRepository;

    @Cacheable
    @RequestMapping(method = RequestMethod.GET, path="/persons/{id}")
    public Person getPerson(@PathVariable(name = "id") long id) {
        return this.personRepository.findById(id);
    }

    @Cacheable
    @RequestMapping(method = RequestMethod.GET, path="/persons")
    public List<Person> findAll() {
        return this.personRepository.findAll();
    }

    @CachePut
    @RequestMapping(method = RequestMethod.POST, path="/save")
    public Person savePerson(@RequestBody Person person) {
        return this.personRepository.save(person);
    }
}

对于第一次调用findAll方法,它将结果存储在"person"缓存中,对于所有后续调用,即使在其间执行了save()操作,它也会返回相同的结果.

我对缓存很新,所以对此的任何建议都会有很大的帮助.

谢谢!
