Environment中获取配置
- 方式一：直接getProperties获取
String bootstrapServers = env.getProperty("hello.kafka.bootstrap-servers"); - 方式二：将属性直接绑定到对象上
BindResult<TestKafkaProperties> kafkaProperties = Binder.get(env).bind("hello.kafka", TestKafkaProperties.class); - 具体Properties类编写
@Data @ConfigurationProperties(prefix = "hello.kafka") public class TestKafkaProperties implements Serializable { private String bootstrapServers ; private List<TestProducerProperties> producers = new ArrayList<>(); @Data public static class TestProducerProperties implements Serializable { private String username ; private String password ; private Integer retries = 0; private Integer batchSize = 16384; private Integer linger = 1; } }
