我把我的项目更新到了spring-boot 2.1.0.RELEASE 版本。
现在我遇到了以下错误：

使用本问题中介绍的属性https://github.com/spring-projects/spring-boot/issues/14778似乎对解决我的问题没有影响。
我如何禁用Cassandra的JMX？
我的当前Cassandra配置如下：
@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;
}
}
ch.sbb.kat.fc.config.CassandraConfig是做什么的？从它的名称来看，我猜测您正在手动配置Cassandra。因此，Boot的自动配置将会被取消，因此该属性将不起作用。 - Andy Wilkinson
