如何在Java中为字段的动态数据类型创建POJO类？

public class DynamicField<T> {
    private String fieldName;
    private T value;

    // 构造函数
    public DynamicField(String fieldName, T value) {
        this.fieldName = fieldName;
        this.value = value;
    }

    // Getter和Setter方法
    public String getFieldName() {
        return fieldName;
    }

    public void setFieldName(String fieldName) {
        this.fieldName = fieldName;
    }

    public T getValue() {
        return value;
    }

    public void setValue(T value) {
        this.value = value;
    }
}

DynamicField<Integer> intField = new DynamicField<>("fieldName", 10);

int value = intField.getValue();
intField.setValue(20);
