2. 测试代码

创建/更新主题

    @Test
    @DisplayName("创建/修改主题")
    public void rocketMQCreateTopic() throws Exception {
        DefaultMQAdminExt adminExt = new DefaultMQAdminExt();
        adminExt.setNamesrvAddr("localhost:9876");
        adminExt.start();
        TopicConfig topicConfig = new TopicConfig();
        topicConfig.setTopicName("testTopic0");
        topicConfig.setReadQueueNums(8);
        topicConfig.setWriteQueueNums(8);
        topicConfig.setPerm(6);
        Set<String> brokerAddress = CommandUtil.fetchMasterAddrByClusterName(adminExt, "DefaultCluster");
        for (String address : brokerAddress) {
            System.out.printf("Broker地址：%s\n", address);
            adminExt.createAndUpdateTopicConfig(address, topicConfig);
        }
    }

查询主题

    @Test
    @DisplayName("查询主题")
    public void rocketMQGetTopic() throws Exception {
        DefaultMQAdminExt adminExt = new DefaultMQAdminExt();
        adminExt.setNamesrvAddr("localhost:9876");
        adminExt.start();
        TopicList topicList = adminExt.fetchAllTopicList();
        Set<String> topicNameList = topicList.getTopicList();
        for (String topicName : topicNameList) {
            System.out.printf("主题：%s\n", topicName);
        }
    }

删除主题

    @Test
    @DisplayName("删除主题")
    public void rocketMQDeleteTopic() throws Exception {
        DefaultMQAdminExt adminExt = new DefaultMQAdminExt();
        adminExt.setNamesrvAddr("localhost:9876");
        adminExt.start();
        adminExt.deleteTopic("testTopic0", "DefaultCluster");
        // 删除之后再查一遍
        TopicList topicList = adminExt.fetchAllTopicList();
        Set<String> topicNameList = topicList.getTopicList();
        for (String topicName : topicNameList) {
            System.out.printf("主题：%s\n", topicName);
        }
    }
