Spring boot 使用Spring boot和Apache Camel连接Kafka群集时获取SSL异常

我的要求是通过SSL将Kafka主题与Spring Boot和Apache Camel连接起来，我已经编写了以下代码，但我遇到了一个错误，如由sun.security.validator.ValidatorException引起的错误：PKIX路径生成失败：sun.security.provider.certpath.SunCertPathBuilderException:找不到请求的目标的有效认证路径此

任何人，请帮助我如何解决这个错误

//in this code i'm configured the SSL
    @Configuration
    public class Testing {
        @Bean
         SSLContextParameters sslContextParameters(){
            KeyStoreParameters store = new KeyStoreParameters();
            store.setResource("kafka.client.truststore.jks");
            store.setPassword("123456");
    
            TrustManagersParameters trust = new TrustManagersParameters();
            trust.setKeyStore(store);
    
            SSLContextParameters parameters = new SSLContextParameters();
            parameters.setTrustManagers(trust);
    
            return parameters;
          }
    
    }

在下面的文件中，我使用sslContextParameters参数调用路由器

    @Autowired
    SSLContextParameters params;
@Override
    public void configure() throws Exception {
    from("{{timerOnce}}").process(consumerCreate).to(
                "https://xx.xx.xx.xxx/consumers/group-id?sslContextParameters=params");

}

******我使用了另一种方法通过SSL连接Kafka群集，但不幸的是它遇到了这样的异常*********org.apache.camel.spring.boot.CamelSpringBootInitializationException:java.io.IOException:无效的密钥库格式

在下面的代码中，我启用了SSL

下面是我使用的路由器端点中的代码

    public void configure() throws Exception {

        Endpoint createEndpoint = cdcHelper.setupSSLConext(context);

        from("{{timerOnce}}").process(consumerCreate)
                .to(createEndpoint);    // calling kafka consumer 

    }
}

您可以按照以下方法使用ApacheCamel和SpringBoot设置Kafka使用者

将以下属性添加到应用程序中。属性

# kafka configuration
kafka.topic=iot1
kafka.camelKafkaOptions.groupId=grp1
kafka.camelKafkaOptions.brokers=kafka.localtest:9093
kafka.camelKafkaOptions.consumersCount=10
kafka.camelKafkaOptions.autoOffsetReset=latest
kafka.camelKafkaOptions.autoCommitEnable=false
kafka.camelKafkaOptions.allowManualCommit=true
kafka.camelKafkaOptions.metadataMaxAgeMs=5000
kafka.camelKafkaOptions.securityProtocol=SSL
kafka.camelKafkaOptions.sslEndpointAlgorithm=HTTPS
kafka.camelKafkaOptions..sslKeyPassword=<ssl key password>
kafka.camelKafkaOptions..sslKeystoreLocation=<keystorepath>
kafka.camelKafkaOptions.sslKeystorePassword=<sslkeystore password>
kafka.camelKafkaOptions.sslTruststoreLocation=<truststore path>
kafka.camelKafkaOptions.sslTruststorePassword=<password>

and create a utility method, to construct a kafka url

@Component
public class KafkaUtility {
      public String getKafkaEndpoint(String topicName ){
       StringBuilder urlBuilder = new StringBuilder("kafka:" + topicName);

        if (!getCamelKafkaOptions().isEmpty()) {
            urlBuilder.append("&");
            getCamelKafkaOptions().forEach(
                (key, value) -> {
                    if (StringUtils.isNotBlank(value)) {
                        appendConfig(urlBuilder, key, value);
                    }
                }
            );
        }
        // strip the last "&" symbol
         String kafkaURL = stripLastAnd(urlBuilder.toString());
        return kafkaURL;
   }
}

In your route builder, implement the below

    @Autowired
    private KafkaUtility kafkaUtility;

  from(kafkaUtility.getKafkaEndpoint())
  .process("yourprocessor")
  .to("tourl");

#卡夫卡配置

卡夫卡。卡夫卡选项..sslKeystoreLocation=
kafka.camelKafkaOptions.sslKeystorePassword=
kafka.camelKafkaOptions.sslTruststoreLocation=

并创建一个实用方法，以构造卡夫卡url
@组成部分
公共级卡夫卡{
公共字符串getKafkaEndpoint（字符串主题名）{
StringBuilder urlBuilder=新的StringBuilder（“卡夫卡：+topicName”）；
如果（！getCamelKafkaOptions（）.isEmpty（））{
urlBuilder.append（“&”）；
getCamelKafkaOptions（）.forEach(
（键、值）->{
if（StringUtils.isNotBlank（值））{
appendConfig（urlBuilder、键、值）；
}
}
);
}
//去掉最后一个“&”符号
字符串kafkaull=stripLastAnd（urlBuilder.toString（））；
返回卡夫卡尔；
}
}
在管线生成器中，执行以下步骤
@自动连线
