问题
I'm doing some tests on Liferay. For this, I'm following the MVC tutorial, and got stuck in the services stuff.
I created a simple entity for testing purposes, "Miclase":
public class Miclase {
int id;
int num1;
String string1;
}
Pretty simple, huh. Well, after this, I started the service builder and created a file like this, with the Overview pane:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE service-builder PUBLIC "-//Liferay//DTD Service Builder 6.2.0//EN" "http://www.liferay.com/dtd/liferay-service-builder_6_2_0.dtd">
<service-builder package-path="asd">
<author>hp</author>
<namespace>Miservicio</namespace>
<entity name="Miclase" local-service="true">
<column name="id" type="int"></column>
<column name="num1" type="int" primary="false"></column>
<column name="string1" type="String"></column>
<!-- PK fields -->
<column name="miclaseId" type="long" primary="true"></column>
<!-- Group instance -->
<column name="groupId" type="long"></column>
<!-- Audit fields -->
<column name="companyId" type="long"></column>
<column name="userId" type="long"></column>
<column name="userName" type="String"></column>
<column name="createDate" type="Date"></column>
<column name="modifiedDate" type="Date"></column>
<finder name="GroupId" return-type="Collection">
<finder-column name="groupId"></finder-column>
</finder>
</entity>
</service-builder>
Everything showed up without errors in the "Overview" pane, so I clicked the "Build service" button, it created a lot of source code:

Did I do something wrong here?
回答1:
I don't know if the "id" column is allowed on liferay or is one of the reserved identifiers for columns on service builder.
Could you try with id_ instead of id for this column?
Hope this helps.
Edit: I've seen you're using Java 8. Please test it with Java 7 and tell us.
回答2:
I'd recommend using Java 7. Seems like you have a tomcat or eclipse not completely Java 8 compatible. Try with Java 7, and if possible, invoking the build-service ant target from a console instead of the IDE.
By the way, please, don't create new threads for the same question (Liferay Service Builder throwing three weird errors). It's not getting more chances to be answered.
回答3:
Which java sdk version are you using? I've tested your service.xml and it worked fine.
I think you need to use java 7 or higher
