spring boot 数据 cassandra 响应式(Reactive) JmxReporter 问题

Question

我将我的项目更新为 spring-boot 版本 2.1.0.RELEASE。
现在我收到以下错误:

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.cassandra.ReactiveSession]: Factory method 'reactiveSession' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'session' defined in class path resource [ch/sbb/kat/fc/config/CassandraConfig.class]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: com/codahale/metrics/JmxReporter

使用本期介绍的属性 https://github.com/spring-projects/spring-boot/issues/14778似乎无法解决我的问题。

如何禁用 cassandra 的 jmx？

我当前的 cassandra 配置如下所示:

@Configuration
@EnableReactiveCassandraRepositories({"repository"})
public class CassandraConfig extends AbstractReactiveCassandraConfiguration {

    @Value("${cassandra.host}")
    private String host;

    @Override
    protected String getKeyspaceName() {
        return "keyspace";
    }

    @Override
    public String[] getEntityBasePackages() {
        return new String[]{"model"};
    }

    @Override
    public SchemaAction getSchemaAction() {
        return SchemaAction.CREATE_IF_NOT_EXISTS;
    }

    @Override
    public String getContactPoints() {
        return host;
    }
}

Answer 1

我在这里尝试了答案，我不知道如何但错误仍然存​​在。
我从 docs.datastax.com 读到这篇文章, 他们谈到搬家 JMX reporting在 Metrics 4到一个单独的模块，metrics-jmx .他们明确表示这可能会导致问题/错误。

为了解决这个问题，我只需要调用这个方法 .withoutJMXReporting()如下所示。

Cluster cluster = Cluster.builder()
        .withoutJMXReporting()
        .build();
