Question

我有一个Spring-Boot 1.5.4项目，该项目需要具有Hazelcast的群集数据库缓存。因此，我进行了以下更改：

pom.xml：

<dependency>
  <groupId>com.hazelcast</groupId>
  <artifactId>hazelcast</artifactId>
</dependency>
<dependency>
  <groupId>com.hazelcast</groupId>
  <artifactId>hazelcast-eureka-one</artifactId>
  <version>1.1</version>
</dependency>
<dependency>
  <groupId>org.mybatis.caches</groupId>
  <artifactId>mybatis-hazelcast</artifactId>
  <version>1.1.1</version>
</dependency>

Bean：

  @Bean
  public Config hazelcastConfig(EurekaClient eurekaClient) {
    EurekaOneDiscoveryStrategyFactory.setEurekaClient(eurekaClient);

    Config config = new Config();
    config.getNetworkConfig().getJoin().getMulticastConfig().setEnabled(false);
    return config;
  }

mapper.xml：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.sjngm.blah.dao.mapper.AttributeMapper">

  <resultMap type="attribute" id="attributeResult">
    ...
  </resultMap>

  <cache type="org.mybatis.caches.hazelcast.HazelcastCache" eviction="LRU" size="100000" flushInterval="600000" />

  ...

我没有hazelcast.xml或eureka-client.properties。

启动正常，但记录以下内容：

它记录两个警告，我不知道为什么。首先，它尝试实例化一个独立实例，然后继续使用并使用Eureka和有关打开的端口5701的“抱怨”。

恕我直言，第一个块根本不应该在那里，这将导致第二个警告不被打印。似乎Hazelcast首先会初始化自己，然后Spring-Boot创建@Bean。

我在这里想念什么？

Answer 1

当您禁用多播时，您没有Hazelcast的连接器。这就是为什么打印

未启用任何加入方法！独立启动。

这是link如何为尤里卡启用它的方法

对于3.7之类的旧版本，您可以通过提供完全限定的类名来配置Eureka。

<network>
<discovery-strategies>
  <discovery-strategy class="com.hazelcast.eureka.one.EurekaOneDiscoveryStrategy" enabled="true">
    <properties>
      <property name="namespace">hazelcast</property>
    </properties>
  </discovery-strategy>
</discovery-strategies>
</network>

P.S：我建议您升级到最新的hazelcast，因为3.7.7版本已经很老了。这里列出了最新的Hazelcast版本。 https://hazelcast.org/download/

Hazelcast：运行群集时避免警告
