我在使用 JAVA 11 的日志文件中以红线显示以下内容。
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.springframework.util.ReflectionUtils (file:/C:/Users/lol/.m2/repository/org/springframework/spring-core/5.1.5.RELEASE/spring-core-5.1.5.RELEASE.jar) to constructor java.math.BigDecimal(java.math.BigInteger,long,int,int)
WARNING: Please consider reporting this to the maintainers of org.springframework.util.ReflectionUtils
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release
我也得到以下信息。这是否意味着 spring-data-redis 有问题

最佳答案
这是带有 Netty 包堆栈跟踪的调试消息。
我在这里找到了解决方案:https://github.com/netty/netty/issues/7817
您需要更改此包的记录器级别以抑制这些警告。
在您的 logback-spring.xml 下面添加这一行以抑制所有消息。
<logger name="io.netty.util" level="ERROR"/>
关于Spring boot 2.1.3.RELEASE 发生了非法的反射访问操作，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/55642897/
