IDEA运行RocketMQ源码调试，该配置的文件都配置了，就是启动失败，broker.log记录的失败日志如下：
2022-02-23 11:58:46 ERROR main - persist file D:/Desktop/rocketmq-all-4.9.2-source-release/home/store configconsumerFilter.json exception java.io.FileNotFoundException: D:Desktoprocketmq-all-4.9.2-source-releasehomestore configconsumerFilter.json.tmp (文件名、目录名或卷标语法不正确。) at java.io.FileOutputStream.open0(Native Method) ~[na:1.8.0_301] at java.io.FileOutputStream.open(FileOutputStream.java:270) ~[na:1.8.0_301] at java.io.FileOutputStream.(FileOutputStream.java:213) ~[na:1.8.0_301] at java.io.FileOutputStream.

java.io.FileNotFoundException: D:Desktoprocketmq-all-4.9.2-source-releasehomestore configconsumerFilter.json.tmp (文件名、目录名或卷标语法不正确。)提示找不到文件。发现store后面多了个空格。原来broker.conf配置文件行尾不可以有空格，否则解析的时候会带上空格。
broker.conf配置文件如下：
brokerClusterName = DefaultCluster brokerName = broker-a brokerId = 0 deleteWhen = 04 fileReservedTime = 48 brokerRole = ASYNC_MASTER flushDiskType = ASYNC_FLUSH #namesrvAddr地址 namesrvAddr=127.0.0.1:9876 #存储路径 storePathRootDir=D:/Desktop/rocketmq-all-4.9.2-source-release/home/store #commitLog存储路径 storePathCommitLog=D:/Desktop/rocketmq-all-4.9.2-source-release/home/store/commitlog #消费队列存储路径 storePathConsumeQueue=D:/Desktop/rocketmq-all-4.9.2-source-release/home/store/consumequeue #消息索引存储路径 storePathIndex=D:/Desktop/rocketmq-all-4.9.2-source-release/home/store/index #checkpoint文件存储路径 storeCheckpoint=D:/Desktop/rocketmq-all-4.9.2-source-release/home/store/checkpoint #abort文件存储路径 abortFile=D:/Desktop/rocketmq-all-4.9.2-source-release/home/store/abort
