Spring Data Neo4j and Grails 3

Question

是否有人拥有使用Grails v3的Spring Data Neo4j（3.3.0）并愿意共享配置？

我想让web界面正常工作（根据以下内容：如何在使用spring-data-neo4j时启用neo4j-webadmin？），但当我试图确定Application.groovy中应该包含什么时，我有点迷失了方向，因为Grails从GrailsAutoConfiguration扩展了它，所示的示例从Neo4jConfiguration扩展了它。

将以下依赖项添加到build.gradle:

compile("org.springframework.data:spring-data-neo4j")
compile "org.neo4j.app:neo4j-server:2.1.5"
compile "org.neo4j.app:neo4j-server:2.1.5:static-web"

下面的资源文件位于conf/spring中。

resources.xml:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <bean id="graphDbBuilder" factory-bean="graphDbFactory" factory-method="newEmbeddedDatabaseBuilder">
        <constructor-arg value="target/data/db"/>
    </bean>
    <bean id="graphDbBuilderFinal" factory-bean="graphDbBuilder" factory-method="setConfig">
        <constructor-arg ref="config"/>
    </bean>
    <bean id="graphDatabaseService" factory-bean="graphDbBuilderFinal" factory-method="newGraphDatabase"
    destroy-method="shutdown"/>
    <bean id="serverWrapper" class="org.neo4j.server.WrappingNeoServerBootstrapper" init-method="start"
        destroy-method="stop">
        <constructor-arg ref="graphDatabaseService"/>
    </bean>
</beans>

resources.groovy（我确信这可能会从resources.xml中添加很多内容，但我不确定该怎么办）：

import com.example.MyGraph;
// Place your Spring DSL code here
beans = {
    myGraph(MyGraph)
}

src/main/groovy/com/example/MyGraph.java:

package com.example;
import org.neo4j.graphdb.GraphDatabaseService;
import org.neo4j.graphdb.Transaction;
import org.neo4j.graphdb.factory.GraphDatabaseFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.neo4j.config.Neo4jConfiguration;
import org.springframework.data.neo4j.core.GraphDatabase;
@Configuration
public class MyGraph extends Neo4jConfiguration {
    @Autowired
    GraphDatabase graphDatabase;
}

我把Neo4J的域类放在了src/main/groovy/com/example/domain中，把存储库类放在src/main/groovy/com/example/repositories中。Spring示例代码工作正常。当您运行grails run-app时，端口7474上有一个Neo4J的web服务器管理界面。
