安裝Tomcat

1.拉取鏡像

docker pull centos/mysql-57-centos7

2.啟動容器設置密碼

docker run -di --name=user_mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=Gas123. centos/mysql-57-centos7

3.設置數據庫的編碼問題 修改為utf-8

SET NAMES 'utf8'; set charset_set_server=utf8set character_set_database=utf8mb4 set character_set_server=utf8mb4

SET NAMES ‘utf8’;它相當于下面的三句指令：
SET character_set_client = utf8;
SET character_set_results = utf8;
SET character_set_connection = utf8;

4.查看數據庫的編碼集

show variables like '%character%';

alter table tablename convert to character set utf8;

5.使用存儲過程修改所有表的編碼（）

CREATE PROCEDURE `pr_convert_dbtab_utf8`(IN dbName varchar(100))BEGINdeclare stop int default 0;declare tabCount int default 0;declare strSql varchar(1000);declare name varchar(100);declare cur CURSOR FOR select table_name from information_schema.tables where table_schema=dbName;declare CONTINUE HANDLER FOR SQLSTATE '02000' SET stop = null;OPEN cur;FETCH cur INTO name;WHILE ( stop is not null) DOset tabCount=tabCount+1;set strSql = concat('alter table `',name,'` convert to character set utf8');set @sql1 = strSql;prepare stmt_p from @sql1;execute stmt_p;FETCH cur INTO name;END WHILE;CLOSE cur;SELECT concat('table: ', tabCount);END;

6.運行函數，修改所有表的編碼

call pr_convert_dbtab_utf8('xianbao');

7.修改表的字段的編碼（單條命令，參考）

alter table `tablename` convert to character set utf8;

它可以修改一張表的所有字段的編碼格式

8.Java的配置文件

spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.datasource.url=jdbc:mysql://ip地址/xianbao?useUnicode=true&useSSL=false&&characterEncoding=utf8 spring.datasource.username=root spring.datasource.password=gaoyuan123. #druid spring.datasource.initial-size=1 spring.datasource.max-active=20 spring.datasource.max-idle=30 spring.datasource.min-idle=5 spring.datasource.max-wait=60000 spring.datasource.time-between-eviction-runs-millis=60000 spring.datasource.min-evictable-idle-time-millis=300000 spring.datasource.test-while-idle=true spring.datasource.test-on-borrow=false spring.datasource.test-on-return=false spring.datasource.pool-prepared-statements=false spring.datasource.max-open-prepared-statements=20 spring.datasource.filters=stat
