activiti兼容达梦数据库

1、继承

SpringProcessEngineConfiguration

重写方法

initDatabaseType(){ 

Connection connection = null;
try {connection = dataSource.getConnection();DatabaseMetaData databaseMetaData = connection.getMetaData();String databaseProductName = databaseMetaData.getDatabaseProductName();log.debug("database product name: '{}'", databaseProductName);if(databaseProductName.contains("DM DBMS")){databaseProductName="Oracle";}databaseType = databaseTypeMappings.getProperty(databaseProductName);if (databaseType==null) {throw new ActivitiException("couldn't deduct database type from database product name '"+databaseProductName+"'");}log.debug("using database type: {}", databaseType);} catch (SQLException e) {log.error("Exception while initializing Database connection", e);
} finally {try {if (connection!=null) {connection.close();}} catch (SQLException e) {log.error("Exception while closing the Database connection", e);}
}

}

2、修改activiti启动配置项
