2.确保mysql-connector-java-版本高于5.1.1-bin.jar
3.正确配置数据库 utf8mb4
[client] port = 3306 socket = /var/run/mysqld/mysqld.sock default-character-set = utf8mb4 [mysqld_safe] socket = /var/run/mysqld/mysqld.sock nice = 0 [mysqld] # # * Basic Settings # user = mysql pid-file = /var/run/mysqld/mysqld.pid socket = /var/run/mysqld/mysqld.sock port = 3306 basedir = /usr datadir = /var/lib/mysql tmpdir = /tmp lc-messages-dir = /usr/share/mysql skip-external-locking collation-server = utf8mb4_general_ci init-connect=?.ET NAMES utf8mb4? character-set-server = utf8mb4 # # Instead of skip-networking the default is now to listen only on # localhost which is more compatible and is not less secure. bind-address = 127.0.0.1 # # * Fine Tuning # key_buffer = 16M max_allowed_packet = 16M thread_stack = 192K thread_cache_size = 8 # This replaces the startup script and checks MyISAM tables if needed # the first time they are touched myisam-recover = BACKUP #max_connections = 100 #table_cache = 64 #thread_concurrency = 10 # # * Query Cache Configuration # query_cache_limit = 1M query_cache_size = 16M # # * Logging and Replication # # Both location gets rotated by the cronjob. # Be aware that this log type is a performance killer. # As of 5.1 you can enable the log at runtime! #general_log_file = /var/log/mysql/mysql.log #general_log = 1 # # Error log - should be very few entries. # log_error = /var/log/mysql/error.log # # Here you can see queries with especially long duration #log_slow_queries = /var/log/mysql/mysql-slow.log #long_query_time = 2 #log-queries-not-using-indexes # # The following can be used as easy to replay backup logs or for replication. # note: if you are setting up a replication slave, see README.Debian about # other settings you may need to change. #server-id = 1 #log_bin = /var/log/mysql/mysql-bin.log expire_logs_days = 10 max_binlog_size = 100M #binlog_do_db = include_database_name #binlog_ignore_db = include_database_name # # * InnoDB # # InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/. # Read the manual for more InnoDB related options.

注意 innodb_large_prefix 、innodb_file_format
检查是否正确
show variables like '%character%'; show variables like 'innodb_large_prefix'; show variables like 'innodb_file_format';
创建UTF8MB4数据库、及测试数据表是否正常插入表情
create database databaseName CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
use databaseName;
create table test (value varchar(255));
insert into asdf values ('表情');
#此处无法粘贴进来。自己找
接下来正常的OFBiz导表流程
如果出现
Specified key was too long; max key length is 767 bytes 或 java.sql.SQLException -> Index Column Size too large。
Maximum Column Size is 767 Byte
--
That error means you are trying to add unique index on a varchar(255) utf8mb4 column. In utf8mb4 column, each character needs 4 bytes. So 255 characters means 1020 bytes. The max key length is 767 bytes.
增加 fieldtypemysql_utf8mb4.xml
详见附件
修改 entityengine.xml
详见附件
使配置适用 Utf8mb4
确保VISIT 等长字段业务正常使用即可。
