贴代码,producer生产配置类

package com.trs.idap.config;
    
    import org.apache.kafka.clients.producer.ProducerConfig;
    import org.apache.kafka.common.serialization.StringSerializer;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.kafka.annotation.EnableKafka;
    import org.springframework.kafka.core.DefaultKafkaProducerFactory;
    import org.springframework.kafka.core.KafkaTemplate;
    import org.springframework.kafka.core.ProducerFactory;
    
    import java.util.HashMap;
    import java.util.Map;
    
    @Configuration
    @EnableKafka
    public class KafkaProducerConfiguration {
        @Value("${spring.data.kafka.producer.servers}")
        private String servers;
        @Value("${spring.data.kafka.producer.retries}")
        private int retries;
        @Value("${spring.data.kafka.producer.batch-size}")
        private int batchSize;
        @Value("${spring.data.kafka.producer.linger}")
        private int linger;
        @Value("${spring.data.kafka.producer.buffer-memory}")
        private int bufferMemory;
        @Bean
        public KafkaTemplate<String, String> kafkaTemplate() {
            return new KafkaTemplate(producerFactory());
        }
        public ProducerFactory<String, String> producerFactory() {
            return new DefaultKafkaProducerFactory<>(producerConfigs());
        }
        public Map<String, Object> producerConfigs() {
            Map<String, Object> props = new HashMap<>();
            props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, servers);
            props.put(ProducerConfig.RETRIES_CONFIG, retries);
            props.put(ProducerConfig.BATCH_SIZE_CONFIG, batchSize);
            props.put(ProducerConfig.LINGER_MS_CONFIG, linger);
            props.put(ProducerConfig.BUFFER_MEMORY_CONFIG, bufferMemory);
            props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
            props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
            return props;
        }
    }

在其他模块调用的时候,只需要注入,直接调用使用就ok了......
