70 | if (!stream.isExists()) { 71 | // 如果stream键不存在，创建group的同时创建stream 72 | stream.createGroup(StreamCreateGroupArgs.name(Order.GROUP_NAME).makeStream()); 73 | } 74 | ``` 75 | 76 | ```shell 77 | if (Boolean.FALSE.equals(template.hasKey(Order.STREAM_KEY))) { 78 | redisConnectionFactory.getConnection().streamCommands() 79 | .xGroupCreate(Order.STREAM_KEY.getBytes(), 80 | Order.GROUP_NAME, 81 | ReadOffset.from("0-0"), 82 | true); 83 | } 84 | ``` 85 | 86 | ```shell 87 | client.getStream(Order.GROUP_NAME).ack(Order.GROUP_NAME, smid); 88 | ``` 89 | 90 | ```shell 91 | template.opsForStream().acknowledge(Order.GROUP_NAME, message); 92 | template.opsForStream().delete(Order.STREAM_KEY, message.getId()); 93 | ``` -------------------------------------------------------------------------------- /webflux-r2dbc-examples/pom.xml: -------------------------------------------------------------------------------- 1 | 2 | 4 | 4.0.0 5 | 6 | org.example 7 | springboot-course 8 | ${revision} 9 | 10 | webflux-r2dbc-examples 11 | 0.0.1-SNAPSHOT 12 | webflux-r2dbc-examples 13 | webflux-r2dbc-examples 14 | 15 | 16 | 17 | org.springframework.security 18 | spring-security-crypto 19 | 20 | 21 | 22 | com.auth0 23 | java-jwt 24 | 4.4.0 25 | 26 | 27 | 28 | org.junit.platform 29 | junit-platform-launcher 30 | test 31 | 32 | 33 | org.springframework.boot 34 | spring-boot-starter-data-r2dbc 35 | 36 | 37 | org.springframework.boot 38 | spring-boot-starter-webflux 39 | 40 | 41 | 42 | org.springframework.boot 43 | spring-boot-devtools 44 | runtime 45 | true 46 | 47 | 48 | com.mysql 49 | mysql-connector-j 50 | runtime 51 | 52 | 53 | io.asyncer 54 | r2dbc-mysql 55 | runtime 56 | 57 | 58 | org.projectlombok 59 | lombok 60 | true 61 | 62 | 63 | org.springframework.boot 64 | spring-boot-starter-test 65 | test 66 | 67 | 68 | io.projectreactor 69 | reactor-test 70 | test 71 | 72 | 73 | 74 | 75 | -------------------------------------------------------------------------------- /spring-examples/src/main/java/org/example/springexamples/example03/aopadvanced/MyAuthAspect.java: -------------------------------------------------------------------------------- 1 | package org.example.springexamples.example03.aopadvanced;
