如何将util java类重用到其他空手道项目中？

Question

    * def kafkaProducer = read('../js/KafkaProducer.js')

function(kafkaConfiguration){
var Producer = Java.type('x.y.core.producer.Producer');
var producer = new Producer(kafkaConfiguration);
return producer;
}

public class Producer {

private static final Logger LOGGER = LoggerFactory.getLogger(Producer.class);

private static final String KEY = "C636E8E238FD7AF97E2E500F8C6F0F4C";
private KafkaConfiguration kafkaConfiguration;
private ObjectMapper mapper;
private AESEncrypter aesEncrypter;


public Producer(KafkaConfiguration kafkaConfiguration) {
    kafkaConfiguration.getProperties().put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringSerializer");
    kafkaConfiguration.getProperties().put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.ByteArraySerializer");
    this.kafkaConfiguration = kafkaConfiguration;
    this.mapper = new ObjectMapper();
    this.aesEncrypter = new AESEncrypter(KEY);
}


public String produceMessage(String payload) {

  // Just notify kafka with payload and return id of payload
}

public class KafkaConfiguration {

private static final Logger LOGGER = LoggerFactory.getLogger(KafkaConfiguration.class);

private Properties properties;

public KafkaConfiguration(String host) {

    try {
        properties = new Properties();
        properties.put(BOOTSTRAP_SERVERS_CONFIG, host);
        properties.put(ConsumerConfig.GROUP_ID_CONFIG, "karate-integration-test");
        properties.put(ConsumerConfig.CLIENT_ID_CONFIG, "offset123");
        properties.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, true);
        properties.put(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "earliest");
    } catch (Exception e) {
        LOGGER.error("Fail creating the consumer...", e);
        throw e;
    }
}

public Properties getProperties() {
    return properties;
}

public void setProperties(Properties properties) {
    this.properties = properties;
}
}

@Then("^Notify kafka with payload (-?\\d+)$")
    public void validateResult(String payload) throws Throwable {
        new Producer(kafkaConfiguration).produceMessage(payload);
    }

Then Notify kafka with payload "{example:value}"

Answer 1

答案很简单，使用普通的Java/Maven概念。将通用Java代码移动到“main”包(src/main/Java)。现在您所需要做的就是构建一个JAR并将其作为依赖项添加到任何空手道项目中。

最后一个难题是：使用类路径:前缀引用JAR中的任何特性或JS文件。空手道就能把他们捡起来。

编辑：抱歉空手道不支持cucumber或步骤定义。它有一个简单得多的方法。详情请阅读:https://github.com/intuit/karate/issues/398
