Spring Boot 中使用自定义keyConverter，DefaultSpringKeyConvertorParser类中当执行parseKeyConvertor方法时applicationContext为null #573

Open zhoujibo opened 3 years ago

zhoujibo commented 3 years ago

环境： Spring Boot：2.3.9.RELEASE jetcache：2.6.0

Spring Boot部分配置：

jetcache:
  statIntervalMinutes: 15
  areaInCacheName: false
  local:
    default:
      type: caffeine
      keyConvertor: myKeyConvertor
      limit: 100
  remote:
    default:
      type: redis.springdata
      keyConvertor: bean:myKeyConvertor
      valueEncoder: java
      valueDecoder: java
      keyPrefix: tecache

使用默认的keyConverter：fastjson没有问题 当使用自定义myKeyConvertor（此bean已在Spring Context中定义）时，启动应用后，当程序执行到DefaultSpringKeyConvertorParser类中parseKeyConvertor方法时applicationContext为null，报java.lang.NullPointerException， stack信息如下：

非常感谢，这个问题确实存在。

但是我想用更简单的方式来修复。这个问题是在jetcache-autoconfigure里面导致的，因此也应该在jetcache-autoconfigure里面修。

我已提交一个修复： https://github.com/alibaba/jetcache/commit/4744330579cb29aa1e00120ec5eb0a579dcaadb3

你的PR我就关掉了。

现在我用修复后的版本 还是出现上面的问题。且我是用test中的例子测试的
