我有一个名为Shape的抽象类，还有三个名为Circle，Triangle和Rectangle的子类。我使用继承类型single来映射这些类。
@Entity
@Table(name = "shape")
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "shape_type")
public abstract class Shape{
public enum ShapeType {
RECTANGLE,
CIRCLE,
TRIANGLE
}
@Column(name = "LENGTH")
private String what;
@ManyToOne(fetch= FetchType.LAZY)
@JoinColumn(name = "color_id")
private Color color;
public Color getColor() {
return color;
}
public void setColor(Color color) {
this.color = color;
}
//getters and setters
}
@Entity
@DiscriminatorValue(value = "RECTANGLE")
public class Rectangle extends Shape {
//proerties
}
@Entity
@DiscriminatorValue(value = "CIRCLE")
public class Circle extends Shape {
//proerties
}
我的问题是，当我为属性“color”添加此getter方法时，我收到异常“无法启动bean documentationPluginsBootstrapper”;嵌套异常是com.google.common.util.concurrent.ExecutionError：java .lang.StackOverflowError “
这是我得到的完整堆栈跟踪

一旦我删除了颜色属性的getter方法，它就可以正常工作了。我通过互联网搜索但无法找到答案。 任何人都可以帮我解决这个问题吗？
