At the moment I moved forward. In ROO-931 its says us "At the moment
the gwt setup command generates request objects for all finder
methods" (from here
https://jira.springsource.org/browse/ROO-931?page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#issue-tabs).
I added 'finder' using Roo shell command: finder add
findEmployeesByDepartmentEquals
After that Roo generated me an Aspect:
privileged aspect Employee_Roo_Finder {
public static Query
Employee.findEmployeesByDepartmentEquals(String department) {
if (department == null || department.length() == 0) throw new
IllegalArgumentException("The department argument is required");
EntityManager em = Employee.entityManager();
Query q = em.createQuery("SELECT Employee FROM Employee AS
employee WHERE employee.department = :department");
q.setParameter("department", department);
return q;
}
and added anotation to Employee.java: @RooEntity(finders =
{"findEmployeesByDepartmentEquals"})
but no request objects generated. My EmployeeRequest.java (generated
and maintained by Roo) looks as follows (I can't see finder methods
there):
@RooGwtMirroredFrom("org.springsource.roo.extrackgae.server.domain.Employee")
@ServiceName("org.springsource.roo.extrackgae.server.domain.Employee")
public interface EmployeeRequest extends RequestContext {
abstract Request<java.lang.Long> countEmployees();
abstract
Request<java.util.List<org.springsource.roo.extrackgae.client.managed.request.EmployeeProxy>>
findAllEmployees();
abstract
Request<java.util.List<org.springsource.roo.extrackgae.client.managed.request.EmployeeProxy>>
findEmployeeEntries(int firstResult, int maxResults);
abstract
Request<org.springsource.roo.extrackgae.client.managed.request.EmployeeProxy>
findEmployee(Long id);
abstract
InstanceRequest<org.springsource.roo.extrackgae.client.managed.request.EmployeeProxy,
java.lang.Void> remove();
abstract
InstanceRequest<org.springsource.roo.extrackgae.client.managed.request.EmployeeProxy,
java.lang.Void> persist();
}
Tell me please where I'm wrong? How to make finder methods works?
