SpringBoot3集成RocketMq场景分析

1、下载5.0版本源码包
rocketmq-all-5.0.0-source-release.zip
2、解压后进入目录，编译打包
mvn -Prelease-all -DskipTests -Dspotbugs.skip=true clean install -U

在distribution/target/rocketmq-5.0.0/rocketmq-5.0.0/bin/runserver.sh

distribution/target/rocketmq-5.0.0/rocketmq-5.0.0/bin/runbroker.sh

1、该目录下
distribution/target/rocketmq-5.0.0/rocketmq-5.0.0/bin/
2、启动NameServer
sh mqnamesrv
输出日志
The Name Server boot success. serializeType=JSON
3、启动Broker+Proxy
sh mqbroker -n localhost:9876 --enable-proxy
输出日志
rocketmq-proxy startup successfully
4、关闭服务
sh mqshutdown namesrv
Send shutdown request to mqnamesrv(18636) OK
sh mqshutdown broker
Send shutdown request to mqbroker with proxy enable OK(18647)

1、下载master源码包
rocketmq-dashboard-master
2、解压后进入目录，编译打包
mvn clean package -Dmaven.test.skip=true
3、启动服务
java -jar target/rocketmq-dashboard-1.0.1-SNAPSHOT.jar
4、输出日志
INFO main - Tomcat started on port(s): 8080 (http) with context path ''
5、访问服务：localhost:8080
