我有一个springboot应用程序，它使用springhateoas公开资源。所有的方法get，post，patch都可以正常工作，除了delete。当我向资源发送删除请求时，它不会返回任何内容响应，但当我请求所有资源时，我删除的项目会再次出现。控制台上没有记录异常。 Postman 请求中没有错误。
我试图删除的资源与另一个pojo有多对一的关联。但是那些没有多对一（有些是一对多）的资源正在被删除。
模式实体

@Entity
@Table(name="Modes")
public class Mode { 
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;
    private String name;

    @OneToMany(mappedBy = "mode", fetch=FetchType.EAGER, cascade = CascadeType.ALL)
    private Set<Expense> expense;

    public Mode() {}

    @Autowired
    public Mode(String name,Set<Expense> expense) {
        this.name = name;
        this.expense = expense;
    }

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

}

类别实体

@Entity
@Table(name="Categories")
public class Category {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;
    private String name;

    @OneToMany(mappedBy = "category", fetch=FetchType.EAGER, cascade = CascadeType.ALL)
    private Set<Expense> expense;

    public Category() { }

    @Autowired
    public Category(String name, Set<Expense> expense) {        
        this.setName(name);     
        this.expense = expense;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

费用主体

@Entity
@Table(name="Expenses")
public class Expense {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;
    private String name;    
    private BigDecimal amount;

    @ManyToOne
    @JoinColumn(name="categoryId")
    private Category category;  

    @ManyToOne
    @JoinColumn(name="modeId")
    private Mode mode;

    private Date date;

    public Expense() {}

    public Expense(String name, BigDecimal amount, Category category, Mode mode, Date date) {
        this.name = name;
        this.amount = amount;
        this.category = category;
        this.mode = mode;
        this.date = date;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public BigDecimal getAmount() {
        return amount;
    }

    public void setAmount(BigDecimal amount) {
        this.amount = amount;
    }

    public Category getCategory() {
        return category;
    }

    public void setCategory(Category category) {
        this.category = category;
    }

    public Mode getMode() {
        return mode;
    }

    public void setMode(Mode mode) {
        this.mode = mode;
    }

    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }

}

我使用的存储库

public interface CategoryRepository extends CrudRepository<Category, Integer> {

}

public interface ExpenseRepository extends CrudRepository<Expense, Integer> {

}

public interface ModeRepository extends CrudRepository<Mode, Integer> {

}

费用删除请求无效
我使用mysql作为数据库，并使用postman测试url
