我对使用EqualsVerifier库的Java 有一些疑问equals和hashCode合同.

想象一下,我们有类似的东西

public abstract class Person {

    protected String name;

    @Override
    public boolean equals(Object obj) {
        // only name is taken into account
    }

    @Override
    public int hashCode() {
        // only name is taken into account
    }

}

以下扩展课程:

public final class Worker extends Person {

    private String workDescription;

    @Override
    public final boolean equals(Object obj) {
        // name and workDescription are taken into account
    }

    @Override
    public final int hashCode() {
        // name …

tests我正在为共享数据列表的两个类创建。当我使用时EqualsVerifier，我收到一个错误，因为它要求我提供包含这两个类共享的数据的列表。

这是错误：

Recursive datastructure. Add prefab values for one of the following types: CustomerView, List<YearConfigView>, YearConfigView

这是@Test班级：

@Test
    public void CustomerViewTest() {
EqualsVerifier.forClass(CustomerView.class).withRedefinedSuperclass().withGenericPrefabValues(CustomerView.class).verify();
        }

@Test
    public void YearConfigViewTest() {
        EqualsVerifier.forClass(YearConfigView.class).suppress(Warning.ALL_FIELDS_SHOULD_BE_USED).verify();
    }

CustomerView.java:

public class CustomerView extends EntityBase<Integer> {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;
    private String name;
    private List<YearConfigView> yearConfigs;

    @JsonProperty("current_year_config")
    public YearConfigView getCurrentYearConfig() {
        if (this.getYearConfigs() == null || this.getYearConfigs().isEmpty()) {
            return null;
        }
        int currentYear = LocalDate.now().getYear();
        return this.yearConfigs.parallelStream().filter(yc …
