Spring Roo 1.2.4: Roo_DataOnDemand方面不填充引用实体

Question

我已经使用roo shell创建了几个带有测试的实体：

roo> entity jpa --class ~.model.Entity1 --testAutomatically --activeRecord
roo> entity jpa --class ~.model.Entity2 --testAutomatically --activeRecord
...
roo> entity jpa --class ~.model.EntityN --testAutomatically --activeRecord

然后，我开始在我的集成开发环境(IntelliJ idea)中创建它们之间的关系，使用JPA注解(@NotNull @OneToOne，@OneToMany等)。在这个过程中，我一直在运行我的集成测试，验证数据库架构。突然，我的一个java.lang.NullPointerException测试失败了。我发现，不知何故，-initized改变了之前生成的Roo_DataOnDemand方面，因此所有引用的实体都变成了“空”roo。

我可以手动执行推入重构并初始化所有引用实体，但这太慢了。roo方面生成器发生了什么？我如何修复这个问题，以便roo生成器正确地初始化所有引用？

看起来Roo在"grouping import语句“方面有问题，比如：

import javax.persistence.*

为了解决这个问题，只需在实体中扩展星号即可。示例如下。

"Buggy“实体：

...
import javax.persistence.*;
...


@RooJavaBean
@RooToString
@RooJpaActiveRecord
@RooEquals
@ValidAdvocateCount
public class Formation {

    @NotNull
    @ManyToOne
    private Acol registrationAcol;

    /**
     */
    @NotNull
    @OneToOne
    private Contacts contacts;

    /**
     */
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "formation")
    private Set<Advocate> advocates = new HashSet<Advocate>();

}

该实体自动生成的方面无效(删除了不相关的详细信息)：

    privileged aspect FormationDataOnDemand_Roo_DataOnDemand {

        declare @type: FormationDataOnDemand: @Component;

        private List<Formation> FormationDataOnDemand.data;

        public Formation FormationDataOnDemand.getNewTransientFormation(int index) {
            Formation obj = new Formation();
            setContacts(obj, index);
            setForm(obj, index);
            setName(obj, index);
            setRate(obj, index);
            setRegistrationAcol(obj, index);
            setResume(obj, index);
            setReviewDate(obj, index);
            setViews(obj, index);
            return obj;
        }

        public void FormationDataOnDemand.setContacts(Formation obj, int index) {
            Contacts contacts = null;
            obj.setContacts(contacts);
        }

        public void FormationDataOnDemand.setRegistrationAcol(Formation obj, int index) {
            Acol registrationAcol = null;
            obj.setRegistrationAcol(registrationAcol);
        }

    }

固定实体导入示例：

import javax.persistence.EnumType;
import javax.persistence.Enumerated;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
import javax.persistence.OneToOne;
import javax.persistence.OneToMany;
import javax.persistence.ManyToOne;
import javax.persistence.CascadeType;
import javax.validation.constraints.NotNull;

在修复之后，这是一个有效的自动生成的方面：

 privileged aspect FormationDataOnDemand_Roo_DataOnDemand {

        declare @type: FormationDataOnDemand: @Component;

        private List<Formation> FormationDataOnDemand.data;

        @Autowired
        ContactsDataOnDemand FormationDataOnDemand.contactsDataOnDemand;

        @Autowired
        AcolDataOnDemand FormationDataOnDemand.acolDataOnDemand;

        public Formation FormationDataOnDemand.getNewTransientFormation(int index) {
            Formation obj = new Formation();
            setContacts(obj, index);
            setForm(obj, index);
            setName(obj, index);
            setRate(obj, index);
            setRegistrationAcol(obj, index);
            setResume(obj, index);
            setReviewDate(obj, index);
            setViews(obj, index);
            return obj;
        }

        public void FormationDataOnDemand.setContacts(Formation obj, int index) {
            Contacts contacts = contactsDataOnDemand.getSpecificContacts(index);
            obj.setContacts(contacts);
        }

        public void FormationDataOnDemand.setRegistrationAcol(Formation obj, int index) {
            Acol registrationAcol = acolDataOnDemand.getRandomAcol();
            obj.setRegistrationAcol(registrationAcol);
        }

    }
