Service builder results not matching database values

[11年前 に Ron J によって更新されました。]

Hi everyone,

I've written a few portlets now using service builder, and all have worked wonderfully except for this last one. I have two entities; eventlist and events, one to many relationship. So I added some logic to the localserviceimpl method and reran service builder, entered some values into the db, and they're in my db if I look w/ psql. So now I'm testing and some of my simple finder methods don't return anything, they match the eventlist id which I grabbed from the db for testing purposes. Now if I use the findAll method, I get a bunch of entities, 13 to be exact although I only have one db entry for the eventlist table. So to get something working I was able to loop through the 13 results and use the newest inserted eventlist. When I now query for my events from that id, I get the correct number of results only their IDs don't match what's in the database, my values in the db are 10,11,12,13,14 but I see in my debug statements

events found by eventlistid : 5
eventId: 2306
eventId: 2307
eventId: 2308
eventId: 2309
eventId: 2310

After tons of experimentation I created a new LR instance to test on and now but didn't seem to make a difference. Anyone experience something similar?

Liferay by default will use caching and lucene (sometimes) for entities getting persisted.

Have you tried reindexing all of the search indexes?

Yup, reindexed searches, cleared db cache, and cleared content caches.

I feel like I have create a new portlet and remake the services. If I modified my service.xml and changed some column names and types, would the old indexes and sql for those columns remain? Can I just delete all the service packages and jar, the sql folder, and drop all the tables in my db to get a 'fresh' service?

OK so I know what the problem is but not sure where or why it's the case. I followed a tutorial for connecting to an existing database, so in my portlet's ext-spring.xml I configured another database, but I did not reference the bean id anywhere in my project (I got it working then commented out refs). So now I just moved my dev to a different computer and I didn't have the tables in my db but if I connected to my external db it was grabbing those values...???? Where could it possibly keep this configuration?

Oh, I see...

You have the datasource defined in ext-spring, but you didn't define the datasource for your entity reference. In this case, the SB code will create a table for the entity in the Liferay database. I'm sure that's happened in both environments now. If you check the Liferay database, you'll find a table "Namespace_Entity" where all of your values are located.

To use the external datasource, you have to add it to the xml definition of the entity. There's an attribute, datasource, which you set to be the bean name for the external datasource.

Build and redeploy the service and you'll see that you're now pulling the values from that datasource rather than the Liferay datasource.
