SpringDataNeo4j没有在Grails中创建唯一的索引/约束

在grails中使用spring-data-neo4j时，我在获取唯一约束方面遇到了一些问题

我怀疑这是因为我没有正确连接它，但是存储库正在被扫描和连接，CRUD正在工作，所以我不确定我做错了什么

我使用的是grails 2.4.3，具有以下依赖项：

  neo4jVerison="2.1.5"
  dependencies {
    compile("org.neo4j:neo4j-community:$neo4jVerison")
    compile("org.neo4j.app:neo4j-server:$neo4jVerison")
    compile("org.neo4j:neo4j-rest-graphdb:2.0.1")
    compile("org.neo4j:neo4j-spatial:0.13-neo4j-2.1.4")
    compile 'org.springframework.data:spring-data-neo4j:3.2.1.RELEASE'
    test group:"org.neo4j", name:"neo4j-kernel", version: "$neo4jVerison", classifier:"tests"
    test "org.grails:grails-datastore-test-support:1.0-grails-2.4"
    test "xmlunit:xmlunit:1.5"
} 

这些bean用于我的测试环境：

testGraphDatabaseFactory(org.neo4j.test.TestGraphDatabaseFactory)
graphDb(GraphDatabaseService) { bean ->
    bean.factoryBean = "testGraphDatabaseFactory"
    bean.factoryMethod = "newImpermanentDatabase"
    bean.destroyMethod = "shutdown"  }

xmlns neo4j:"http://www.springframework.org/schema/data/neo4j"
neo4j.'repositories'( 'base-package': "repositories" )
neo4jTemplate(Neo4jTemplate, graphDb)
neo4jMappingContext(Neo4jMappingContext)
tx(NeoTransactions, graphDb)

tx类只公开一个启动graphDb事务的“tx.tx{closure}”方法，即使关闭失败也会关闭它

我的域类是：

package repositories

import org.springframework.data.neo4j.annotation.GraphId
import org.springframework.data.neo4j.annotation.Indexed
import org.springframework.data.neo4j.annotation.NodeEntity

@NodeEntity
class Junction {
    @GraphId Long id;
    @Indexed(unique = true) Long legacyId
}

存储库是：

package repositories

import org.springframework.data.neo4j.repository.GraphRepository

interface JunctionRepository extends GraphRepository<Junction> {}

奇怪的是，虽然只保存了一个连接（即1==junctionRepository.count（）），但在我尝试保存修改后的j3时没有引发异常

此外，当我在Neo4J web控制台中打开数据库并运行：schema时，它不会显示为创建了任何索引/约束

我猜我的连接没有正确配置，因为我认为应该在连接时解析域对象时设置索引

有人知道少了什么吗

后续行动1：

我怀疑我不应该手动创建模板或映射上下文。标准弹簧配置似乎是

但是，当我尝试通过spring dsl执行此操作时，我遇到了一个奇怪的错误：

 xmlns neo4j:"http://www.springframework.org/schema/data/neo4j"
 neo4j.'repositories'( 'base-package': "repositories" )
 neo4j.'config'( 'graphDatabaseService': "graphDb" )

错误是：

| Error Fatal error running tests: Error creating bean with name 'junctionRepository':
  Cannot resolve reference to bean 'neo4jTemplate' while setting bean property 'neo4jTemplate';
  nested exception is org.springframework.beans.factory.BeanCreationException: Error creating
   bean with name 'neo4jTemplate' defined in class org.springframework.data.neo4j.config.Neo4jConfiguration:

嗯：没有定义名为“graphDatabaseService”的bean？那是虫子吗neo4j.config'（'graphDatabaseService'：“graphDb”）告诉它使用graphDbbean，不是吗

后续行动2：

如果我将bean名称更改为graphDatabaseService，它可以正常工作。看起来neo4j.config没有将命名的graphDb bean传递给它构造的所有对象。：）

是的，它确实依赖于名称

graphDatabaseService

（不幸的是）

还要确保你的tx类也调用了

tx.success（）

而不仅仅是

tx.close（）

，这在文档中并不清楚-花费了我几天的时间在黑暗中摸索：（[只有当我来写它的时候，我才真正解决了这个问题……令人惊讶的是，向别人解释它能巩固我的想法].是的，我的tx.tx确实调用success and close:）。Tnx。
