neo4j图数据库中创建关系的时候动态修改@RelationshipEntity(type = “xxx“)的关系名称_neo4j@relationship

本方法是通过反射去获取类上注解的value值并修改

@Data
@NoArgsConstructor
@RelationshipEntity(type = "属于")
public class BelongToRelation extends AbstractRelation<CIType, CIType>{
}

 public Class<BelongToRelation> updateAnnotationValue(String str) throws IllegalAccessException, NoSuchFieldException {
        Class<BelongToRelation> belongToRelationClass = BelongToRelation.class;
 
        RelationshipEntity annotation = belongToRelationClass.getAnnotation(RelationshipEntity.class);
        String type = annotation.type();
 
        System.out.println(type);
        //获取这个代理实例所持有的 InvocationHandler
        InvocationHandler invocationHandler = Proxy.getInvocationHandler(annotation);
        // 获取 AnnotationInvocationHandler 的 memberValues 字段
        Field declaredField = invocationHandler.getClass().getDeclaredField("memberValues");
        // 因为这个字段事
