From: Roland Häder Date: Sat, 9 Sep 2017 12:18:10 +0000 (+0200) Subject: Please cherry-pick: X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=596ad96c7c2085adda9f6560093412745794ce02;p=jfinancials-ejb.git Please cherry-pick: - introduced isSameCompanyNameAdded() which encapsulates checking for if a company name has already been used. This is, together with the thrown checked exception a last effort to prevent bad bad SqlException or any other "low-level" exception as they are more severage than this. - thumb of a rule: always pre-validate if all conditions are met (return "okay") prior doing risky things where uncontrolled exceptions may be thrown. - make company-owner (User), founder (Employee) and contact person (dito) managed before persisting the whole BasicData instance as this makes sure that no duplicates will end up in database Signed-off-by: Roland Häder --- diff --git a/src/java/org/mxchange/jcontactsbusiness/basicdata/FinancialsAdminBusinessDataSessionBean.java b/src/java/org/mxchange/jcontactsbusiness/basicdata/FinancialsAdminBusinessDataSessionBean.java index c00b268..c786968 100644 --- a/src/java/org/mxchange/jcontactsbusiness/basicdata/FinancialsAdminBusinessDataSessionBean.java +++ b/src/java/org/mxchange/jcontactsbusiness/basicdata/FinancialsAdminBusinessDataSessionBean.java @@ -22,8 +22,10 @@ import java.util.List; import java.util.Objects; import javax.ejb.EJB; import javax.ejb.Stateless; +import org.mxchange.jcontactsbusiness.employee.Employee; import org.mxchange.jcontactsbusiness.exceptions.basicdata.BusinessDataAlreadyAddedException; import org.mxchange.jfinancials.database.BaseFinancialsDatabaseBean; +import org.mxchange.jusercore.model.user.User; /** * An administrative stateless session bean for business data @@ -64,25 +66,40 @@ public class FinancialsAdminBusinessDataSessionBean extends BaseFinancialsDataba } else if (basicData.getBasicDataId() != null) { // Should be null throw new IllegalArgumentException(MessageFormat.format("basicData.basicDataId={0} - is not null", basicData.getBasicDataId())); //NOI18N + } else if (this.isSameCompanyNameAdded(basicData)) { + // Throw exception + throw new BusinessDataAlreadyAddedException(basicData); } - // Get all available entries - final List list = this.businessDataBean.allCompanyBasicData(); + // Now add current date + basicData.setCompanyCreated(new GregorianCalendar()); - // Is the list filled? - if (!list.isEmpty()) { - // Then check each entry - for (final BusinessBasicData entry : list) { - // Is the company name matching? - if (Objects.equals(entry.getCompanyName(), basicData.getCompanyName())) { - // Found match - throw new BusinessDataAlreadyAddedException(basicData); - } - } + // Is there a owner set? + if (basicData.getCompanyUserOwner() instanceof User) { + // Get managed instance + final User managedUser = this.createManaged(basicData.getCompanyUserOwner()); + + // Set it back + basicData.setCompanyUserOwner(managedUser); } - // Now add current date - basicData.setCompanyCreated(new GregorianCalendar()); + // Is a founder set? + if (basicData.getCompanyFounder() instanceof Employee) { + // Get managed instance + final Employee managedEmployee = this.createManaged(basicData.getCompanyFounder()); + + // Set it back + basicData.setCompanyFounder(managedEmployee); + } + + // Is a contact person set? + if (basicData.getCompanyContactEmployee() instanceof Employee) { + // Get managed instance + final Employee managedEmployee = this.createManaged(basicData.getCompanyContactEmployee()); + + // Set it back + basicData.setCompanyContactEmployee(managedEmployee); + } // Persist it this.getEntityManager().persist(basicData); @@ -94,4 +111,31 @@ public class FinancialsAdminBusinessDataSessionBean extends BaseFinancialsDataba return basicData; } + /** + * Checks if given basic data is already added by it's company name + *
