Creating Timestamp column with ormlite

问题

I have a column like this:

@DatabaseField(dataType = DataType.TIME_STAMP)
Timestamp time;

When I create the DAO I get this exception:

java.lang.IllegalArgumentException: Field class class java.sql.Timestamp for
    field FieldType:name=time,class=Vote is not valid for data persister
    com.j256.ormlite.field.types.TimeStampType@334ecfe8

It's been one day that I'm trying different methods and none is working. Note that I have updated my ormlite jar to 4.41.

回答1:

Support for java.sql.Timestamp and java.sql.Date fields was added in ORMLite version 4.41 but they had an associated bug. These were fixed in version 4.42.

In the meantime, I think you might be able to fix it by removing the dataType specifier. I think that it should be able to auto-detect the type. The problem is when you are specifying the data-type.

// no dataType specified
@DatabaseField
Timestamp time;
