Question

Resilience4j版本：1.1.0

Java版本：1.8.0_221

问题描述：我正在尝试将Resilience4j与WebFlux一起使用。

我添加了以下依赖项，但尚未添加任何Resilience4j特定代码：

<dependency>
    <groupId>io.github.resilience4j</groupId>
    <artifactId>resilience4j-reactor</artifactId>
    <version>1.1.0</version>
</dependency>
<dependency>
    <groupId>io.github.resilience4j</groupId>
    <artifactId>resilience4j-spring-boot2</artifactId>
    <version>1.1.0</version>
</dependency>

启动服务器时出现以下错误：

Answer 1

resilience4j具有多种功能，例如断路器，重试，速率限制器，隔板。

如果您不想要所有这些功能，并且只希望使用回退机制，请继续在pom.xml文件中添加以下依赖项：
