NodeBacked实体NPE-实体状态为null [英] NodeBacked entity NPE - entityState is null

问题描述

我有一个示例项目，该项目使用Spring Data Neo4j通过Aspectj进行的高级映射.在NullPointerException的测试中失败，这是因为在持久化实体时，entityState属性为null.

I've got a sample project which uses Spring Data Neo4j's advanced mapping using aspectj. It's failing in a test with NullPointerException due to the entityState attribute being null at the time when the entity is being persisted.

当服务器本身启动并执行时，我也可以复制此代码:

I can also replicate this when the server itself is spun up and I execute:

curl -i -X POST -H "Content-Type:application/json" -d '{  "firstName" : "Test",  "lastName" : "Person" }' http://localhost:8080/people

该项目位于 https://github.com/dhallam/spring-data- neo4j-demo ，带有日志的Travis构建位于 https://travis-ci.org/dhallam/spring-data-neo4j-demo/builds/22538972 .

The project is at https://github.com/dhallam/spring-data-neo4j-demo and the Travis build with the logs is at https://travis-ci.org/dhallam/spring-data-neo4j-demo/builds/22538972.

我不确定我是否缺少某些东西，或者是否存在需要我提出JIRA问题的错误.

I'm not sure whether I'm missing something or there is a bug that would require me to raise a JIRA issue.

有什么想法吗?预先非常感谢.

Any ideas? Many thanks in advance.

尝试从下面迈克尔的评论中将@JsonIgnoreProperties添加到Person(@NodeEntity)，但仍然失败.失败的代码是当我运行时:

Tried adding @JsonIgnoreProperties to the Person (@NodeEntity)from Michael's comment below and it's still failing. The bit of code that is failing is when I run:

Person p = new Person();
// setters ...
p.persist();

persist()调用

public <T extends NodeBacked> T NodeBacked.persist() {
    return (T)this.entityState.persist();
}

但entityState为空.

推荐答案

弄清楚了. Neo4jConfig类以前扩展了Neo4jConfiguration类.随着方面的引入，需要将该超类更新为Neo4jAspectConfiguration，以提供其他的neo4jRelationshipBacking和neo4jNodeBacking bean.

Figured it out. The Neo4jConfig class previously extended the Neo4jConfiguration class. With the introduction of aspects, that superclass needed to be updated to be Neo4jAspectConfiguration to provide the additional neo4jRelationshipBacking and neo4jNodeBacking beans.

我已经在 https://github.com/dhallam上更新了github参考项目./spring-data-neo4j-demo ，构建就通过了.

I've updated the github reference project at https://github.com/dhallam/spring-data-neo4j-demo and the build is passing.
