Question

Most databases allow to have field with current timestamp (act as creation timestamp), for example in MySQL:

CREATE TABLE t (ts TIMESTAMP DEFAULT CURRENT_TIMESTAMP)

How to achieve this in Spring Roo? Can’t find hint from Roo manual.

Thanks.

Answer 1

This would be created with:

field date --fieldName ts --type java.util.Date --persistenceType JPA_TIMESTAMP

This will add:

 @Temporal(TemporalType.TIMESTAMP) 

to the field, which should cause the auto-generator to create a TIMESTAMP field. If you want more control, you can always annotate the generated entity field further with

 @Column(name="ts", columnDefinition="TIMESTAMP DEFAULT CURRENT_TIMESTAMP")
