DB connection for DDL in groovy

Yayınlanma tarihi 14 Aralık 2017 Yayınlanma zamanı 10:10.

Tarafından yazılmıştır Mustafa Kerim Yılmaz

DANGER!!!

In hybris hac, you cannot run DDL (data definition language) commands. You need unprotected connection to db. You can use below groovy example. Attention: DDL commands are dangerous!!!

import java.util.List;
import javax.sql.DataSource;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.DriverManagerDataSource;

def config = spring.getBean("configurationService").getConfiguration();

DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(config.getString("db.driver"));
dataSource.setUrl(config.getString("db.url"));
dataSource.setUsername(config.getString("db.username"));
dataSource.setPassword(config.getString("db.password"));
JdbcTemplate jdbc = new JdbcTemplate(dataSource)
jdbc.execute("ALTER TABLE MYTABLE ALTER (P_MYFIELD BIGINT)");

Tarafından yazılmıştır Mustafa Kerim Yılmaz

Below example logging flexiblesearch class to separate file with time based trigger policy. Also we can add rollover strategy for removing old files.

log4j2.appender.FlexlogAppender.type=RollingFile log4j2.appender.FlexlogAppender.name=FlexlogAppender
log4j2.appender.FlexlogAppender.fileName=${HYBRIS_LOG_DIR}/Flexlog.log
log4j2.appender.FlexlogAppender.filePattern=${HYBRIS_LOG_DIR}/Flexlog.log-%d{yyyy-MM-dd}.log
log4j2.appender.FlexlogAppender.ImmediateFlush=true log4j2.appender.FlexlogAppender.layout.type=PatternLayout
log4j2.appender.FlexlogAppender.layout.pattern=%m%n log4j2.appender.FlexlogAppender.policies.type = Policies
log4j2.appender.FlexlogAppender.policies.time.type = TimeBasedTriggeringPolicy log4j2.appender.FlexlogAppender.policies.time.interval = 1000000
log4j2.appender.FlexlogAppender.policies.time.modulate = true log4j2.logger.flexible.name = de.hybris.platform.jalo.flexiblesearch
log4j2.logger.flexible.level = DEBUG log4j2.logger.flexible.appenderRef.stdout.ref = FlexlogAppender log4j2.logger.flexible.additivity = false

Changing item attribute type in hybris

Yayınlanma tarihi 02 Kasım 2017 Yayınlanma zamanı 12:32.

Tarafından yazılmıştır Mustafa Kerim Yılmaz

Some times you need attribute type change in hybris. Hybris as own ORM and it is not support updating attribute type. If you change attribute type you will get error like this:

de.hybris.platform.servicelayer.exceptions.ModelSavingException: <########## NewPropError ##########> value type mismatch in unlocalized property ‘myproperty’ of ‘myitem’ : expected ‘class java.lang.Integer’ but got ‘class java.lang.Long’

If you don’t want to adding new field than migrating data and removing old, you can use below procedure.

Change column type in DB. You cannot do this on hac because DDL disabled (solution added as related pot).
Update system in hac (Platform -> Update without Create essential data option).
