无法使用Resilience4J将CircuitBreaker解析为类型

Question

我试图在我的Spring Boot（使用Swagger）中构建一个简单的断路器。

import...
import io.github.resilience4j.*;

public class AccountServiceImpl implements AccountService {

 Autowired private RestTemplate restTemplate;

  @CircuitBreaker( name = "test", fallbackMethod = "fallback")   
  public void createAccount(ConsentRequestDTO consent) {
    //code which makes the post
    //
  }

  public String fallback() {
    return "fallback-exceptiont";
  }
}

    <groupId>io.github.resilience4j</groupId>
    <artifactId>resilience4j-spring-boot2</artifactId>
    <version>1.7.0</version>
  </dependency>

<dependency>

      <artifactId>resilience4j-all</artifactId>

    </dependency>

CircuitBreakerConfig config = CircuitBreakerConfig.ofDefaults()

但它给出了同样的错误，“无法解决”。

Answer 1

基于你不需要的断路器演示

<dependency>
    <groupId>io.github.resilience4j</groupId>
    <artifactId>resilience4j-spring-boot2</artifactId>
    <version>1.7.0</version>
  </dependency>

因为您已经有spring-cloud-starter-circuitbreaker-reactor-resilience4j。使用这些导入可以解决您的问题
