自定义Source
package com.dist.ytgz.approve.rocketmq; import org.springframework.cloud.stream.annotation.Output; import org.springframework.messaging.MessageChannel; /** * 自定义Source * * @author <a href="mailto:[email protected]">Zhang Xiao</a> * @since */ public interface MySource { String GIS_GROUP_OUT = "gis_group_out"; @Output(MySource.GIS_GROUP_OUT) MessageChannel gisGroupOut(); } -
发送消息
// spring cloud stream里面发消息通过 Source 发送 @Autowired private MySource source; // 发送消息的方法 withPayload(T payload) 所以是传任意类型, 把对应的CONTENT_TYPE, APPLICATION_JSON设置好就行 source.gisGroupOut().send( MessageBuilder .withPayload(messagePayload) .setHeader(MessageHeaders.CONTENT_TYPE, MimeTypeUtils.APPLICATION_JSON).build() ); -
启动类
/** * 记得添加@EnableBinding注解指定消息信道 * Sink.class 表示信道 input , Source.class 表示信道 output * 这两个分别与application.yml中的spring.cloud.stream.bindings.input和spring.cloud.stream.bindings.output对应 * 如果信道名称换成是sender和receiver，就得配置spring.cloud.stream.bindings.sender和spring.cloud.stream.bindings.receiver * * * 而我这里是gis_group_out 所以 spring.cloud.stream.bindings.gis_group_out */ // @EnableBinding(value = {Sink.class, Source.class}) @EnableBinding(value = Source.class) @SpringBootApplication public class ApproveApplication { public static void main(String[] args) { SpringApplication.run(ApproveApplication.class, args); } }
