您需要更新此依赖项：

        <dependency>
            <groupId>io.projectreactor</groupId>
            <artifactId>reactor-core</artifactId>
            <version>3.3.22.RELEASE</version>
        </dependency>

至版本3.4。x作为springboot 2.5.12使用reactor。净值1.0.18，取决于Reactor堆芯3.4。x（比较https://github.com/reactor/reactor-netty/issues/1388)但你迫使maven使用旧的Reactor核心版本

    问题内容： 我对JUnit还是很陌生，我真的不知道对于异常和异常处理有什么最佳实践。 例如，假设我正在为IPAddress类编写测试。它具有一个构造函数IPAddress（String addr），如果addr为null，则将抛出InvalidIPAddressException。据我可以从谷歌搜索中得知，对null参数的测试将如下所示。 在这种情况下，try / catch很有意义，因为我知道异
