我使用 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,我开始使用 JPA 注释(@NotNull @OneToOne、@OneToMany 等)在我的 IDE(IntelliJ 想法)中创建它们之间的关系。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,我的一项测试因 java.lang.NullPointerException 而失败。我发现,roo 以某种方式改变了先前生成的 Roo_DataOnDemand 方面,因此所有引用的实体都变成了“空”初始化。

我可以进行 Push-In 重构并手动初始化所​​有引用实体,但这太慢了。roo 方面生成器发生了什么?我该如何解决这个问题,以便 roo 生成器正确初始化所有引用?

看起来 Roo 在“分组导入语句”方面存在问题,例如:

import javax.persistence.*

为了解决这个问题,只需在您的实体中展开星号。示例如下。

“越野车”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>();

}

该实体的无效自动生成方面(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);
        }

    }
