折腾:
【未解决】用vuejs搭建智能电力管理系统的前端页面
期间,先去运行服务端:
cd /Users/crifan/dev/dev_root/projects/xxx/src/server/xxx/xxx
java -jar target/xxx-0.0.1-SNAPSHOT.jar
结果接口不可用:
http://localhost:8080/iec104/add/

    "data": "68 59 F0 D2 00 00 15 A6 14 00 05 00 01 07 00 02 00 00 00 00 00 CF 5D 96 5D B2 5D 45 00 01 00 FE FF 7C 00 84 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 86 13 00 00 02 00 00 00 00 00 FE FF 00 00 00 00 98 00 00 00 00 00 02 00 00 00 00 00 "
}

    "status": 404,
    "error": "Not Found",
    "message": "No message available",
    "path": "/iec104/add/"
}
然后尝试去试试:
mvn spring-boot:run

mvn clean package
结果都是报错:
log太多:
最后好不容易,才从终端里面找到第一个error:
2020-02-24 21:15:40,560 INFO  HikariDataSource.java:110 - HikariPool-1 - Starting...
2020-02-24 21:15:40,708 ERROR HikariPool.java:595 - HikariPool-1 - Exception during pool initialization.

        at com.mysql.cj.jdbc.exceptions.SQLError.createCommunicationsException(SQLError.java:174) ~[mysql-connector-java-8.0.18.jar:8.0.18]
难道是此处mysql没启动?

问题依旧:
Sequel pro中去连接试试,结果也是连不上:
Connection failed!

Unable to connect to host 127.0.0.1, or the request timed out.

Be sure that the address is correct and that you have the necessary privileges, or try increasing the connection timeout (currently 10 seconds).

MySQL said: Can't connect to MySQL server on '127.0.0.1' (61)
去搞清楚,为何mysql此处没正常启动。
参考:
【未解决】Mac中Sequel连接MySQL失败:Authentication plugin ‘caching_sha2_password’ cannot be loaded: dlopen(/usr/local/lib/plugin/caching_sha2_password.so, 2): image not found
试试:
brew services restart mysql
结果报错:
➜  ~ brew services restart mysql

Error: Formula `mysql` is not installed.
然后再去看看之前的:
【记录】mac搭建开发环境:安装MySQL
【已解决】mac中/usr/local/mysql/support-files/mysql.server中的mysql的配置文件在哪里
再去试试
➜  ~ /usr/local/mysql/support-files/mysql.server status
 ERROR! MySQL is not running, but PID file exists
➜  ~ /usr/local/mysql/support-files/mysql.server start
Starting MySQL
 SUCCESS!
➜  ~ /usr/local/mysql/support-files/mysql.server status
 SUCCESS! MySQL running (24638)
然后看到设置中的MySQL状态也是running了:
此处127.0.0.1中的mysql可以用Sequel连接了:
重新去试试maven的spring boot
mvn spring-boot:run
就可以正常运行了:

再去
mvn clean package
是可以的:

}
就正常了。
【总结】
此处,去启动spring boot的服务端:
mvn spring-boot:run
或:
mvn clean package
java -jar target/xxx-0.0.1-SNAPSHOT.jar
但是报错:
ERROR HikariPool.java:595 – HikariPool-1 – Exception during pool initialization.
com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure
原因:
mysql没有启动。
导致此处mysql的jdbc的Hikari连接不上。
解决办法:
此处mac中启动mysql
/usr/local/mysql/support-files/mysql.server start
即可。
