更新時間：2024年06月17日 15:32:28 作者：萬物~

這篇文章主要介紹了解決SpringBoot2.1.0+RocketMQ版本沖突問題,具有很好的參考價(jià)值,希望對大家有所幫助,如有錯誤或未考慮完全的地方,望不吝賜教

介紹
列一下主要的pom
application.properties配置
代碼
然后關(guān)鍵來了，項(xiàng)目啟動后報(bào)錯
下面列一下@ConditionalOnProperty注解參數(shù)的意思
將application中的配置改為
改完后啟動再次報(bào)錯
然后啟動項(xiàng)目，沒有報(bào)錯，完美解決

介紹

我的項(xiàng)目使用的是springboot2.1.0
rocketmq-spring-boot-starter 使用的是2.0.2
RocketMQ-client使用的版本是4.3.2
RocketMQ使用阿里云的docker搭建

列一下主要的pom

<!--RocketMQ相關(guān)-->
        <dependency>
            <groupId>org.apache.rocketmq</groupId>
            <artifactId>rocketmq-spring-boot-starter</artifactId>
            <version>2.0.2</version>
        </dependency>
        <dependency>
            <groupId>org.apache.rocketmq</groupId>
            <artifactId>rocketmq-client</artifactId>
            <version>4.4.0</version>
        </dependency>

application.properties配置

# RocketMQ相關(guān)配置
spring.rocketmq.nameServer=ip:9876
spring.rocketmq.producer.group=test

代碼

    @Autowired
    private RocketMQTemplate rocketMQTemplate;

     public void test(){
        try {
            // 使用rockMq發(fā)送消息
            HashMap<String, Object> msg = new HashMap<>(2);
            msg.put("id",user.getId());
            msg.put("mobile",mobile);
            msg.put("date",new Date());
            this.rocketMQTemplate.convertAndSend("login",msg);
        }catch (Exception e){
            LOGGER.error("發(fā)送消息出錯",e);
        }
}

然后關(guān)鍵來了，項(xiàng)目啟動后報(bào)錯

Description:

Field rocketMQTemplate in com.tanhua.sso.service.UserService required a bean of type 'org.apache.rocketmq.spring.core.RocketMQTemplate' that could not be found.

The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)

The following candidates were found but could not be injected:
- Bean method 'rocketMQTemplate' in 'RocketMQAutoConfiguration' not loaded because @ConditionalOnProperty (rocketmq.name-server) did not find property 'name-server'

Action:

Consider revisiting the entries above or defining a bean of type 'org.apache.rocketmq.spring.core.RocketMQTemplate' in your configuration.

這里網(wǎng)上查了很多資料都沒有解決，定位到問題的原因是因?yàn)閛rg.apache.rocketmq.spring.autoconfigure.RocketMQAutoConfiguration類的問題

@Configuration
@EnableConfigurationProperties(RocketMQProperties.class)
@ConditionalOnClass({ MQAdmin.class, ObjectMapper.class })
@ConditionalOnProperty(prefix = "rocketmq", value = "name-server")
@Import({ JacksonFallbackConfiguration.class, ListenerContainerConfiguration.class })
@AutoConfigureAfter(JacksonAutoConfiguration.class)
public class RocketMQAutoConfiguration {

    @Bean
    @ConditionalOnMissingBean(DefaultMQProducer.class)
    @ConditionalOnProperty(prefix = "rocketmq", value = {"name-server", "producer.group"})
    public DefaultMQProducer defaultMQProducer(RocketMQProperties rocketMQProperties) {
        RocketMQProperties.Producer producerConfig = rocketMQProperties.getProducer();
        String nameServer = rocketMQProperties.getNameServer();
        String groupName = producerConfig.getGroup();
        Assert.hasText(nameServer, "[rocketmq.name-server] must not be null");
        Assert.hasText(groupName, "[rocketmq.producer.group] must not be null");

        DefaultMQProducer producer;
        String ak = rocketMQProperties.getProducer().getAccessKey();
        String sk = rocketMQProperties.getProducer().getSecretKey();
        if (!StringUtils.isEmpty(ak) && !StringUtils.isEmpty(sk)) {
            producer = new DefaultMQProducer(groupName, new AclClientRPCHook(new SessionCredentials(ak, sk)),
                rocketMQProperties.getProducer().isEnableMsgTrace(),
                rocketMQProperties.getProducer().getCustomizedTraceTopic());
            producer.setVipChannelEnabled(false);
        } else {
            producer = new DefaultMQProducer(groupName, rocketMQProperties.getProducer().isEnableMsgTrace(),
                rocketMQProperties.getProducer().getCustomizedTraceTopic());
        }

        producer.setNamesrvAddr(nameServer);
        producer.setSendMsgTimeout(producerConfig.getSendMessageTimeout());
        producer.setRetryTimesWhenSendFailed(producerConfig.getRetryTimesWhenSendFailed());
        producer.setRetryTimesWhenSendAsyncFailed(producerConfig.getRetryTimesWhenSendAsyncFailed());
        producer.setMaxMessageSize(producerConfig.getMaxMessageSize());
        producer.setCompressMsgBodyOverHowmuch(producerConfig.getCompressMessageBodyThreshold());
        producer.setRetryAnotherBrokerWhenNotStoreOK(producerConfig.isRetryNextServer());

        return producer;
    }

從報(bào)錯信息發(fā)現(xiàn)可能是nameSever不匹配name-server導(dǎo)致，對應(yīng)類中是@ConditionalOnProperty(prefix = “rocketmq”, value = “name-server”)這個注解

下面列一下@ConditionalOnProperty注解參數(shù)的意思

prefix application.properties配置的前綴
name 屬性是從application.properties配置文件中讀取屬性值

所以猜測配置文件要修改成對應(yīng)的參數(shù)才行

將application中的配置改為

rocketmq.name-server=ip:9876
rocketmq.producer.group=test

改完后啟動再次報(bào)錯

Description:

An attempt was made to call the method org.apache.rocketmq.client.producer.DefaultMQProducer.<init>(Ljava/lang/String;ZLjava/lang/String;)V but it does not exist. Its class, org.apache.rocketmq.client.producer.DefaultMQProducer, is available from the following locations:

jar:file:/D:/maven/yycg_repository/org/apache/rocketmq/rocketmq-client/4.3.2/rocketmq-client-4.3.2.jar!/org/apache/rocketmq/client/producer/DefaultMQProducer.class

It was loaded from the following location:

file:/D:/maven/yycg_repository/org/apache/rocketmq/rocketmq-client/4.3.2/rocketmq-client-4.3.2.jar

這次的報(bào)錯是版本沖突問題，經(jīng)過我無數(shù)次的實(shí)驗(yàn)(流淚)，最終將RocketMQ-client使用的版本是4.3.2改為4.4.0解決
