Question

我正在尝试将neo4j与spring-data和scala一起使用，但我得到了这个例外：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'neo4jTemplate': Invocation of init method failed; nested exception is java.lang.NoSuchMethodError:scala.collection.JavaConverters$.mapAsScalaMapConverter(Ljava/util/Map;)Lscala/collection/JavaConverters$AsScala;

目前，我不确定如何“注入”JavaConverters ......

有什么想法吗？

更新：

我试图简单地将导入放在Test类中：

导入scala.collection.JavaConverters ._

但是没有用，这是完整的代码：

WordsTest.scala

package com.dimeder.llull.security

import org.junit.runner.RunWith
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner
import org.springframework.test.context.ContextConfiguration
import org.junit.Test
import org.slf4j.LoggerFactory
import org.springframework.transaction.annotation.Transactional
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.data.neo4j.support.Neo4jTemplate
import com.dimeder.llull.models.Word
import scala.collection.JavaConverters._

@RunWith(classOf[SpringJUnit4ClassRunner])
@ContextConfiguration(Array("classpath:applicationContext-test.xml"))
class WordsTest {
         val logger = LoggerFactory.getLogger(classOf[WordsTest])

  @Autowired
  var template:Neo4jTemplate = _

  @Test
  @Transactional
  def speak(){
      val word:Word = new Word
    word.text="sustancia"
    template.save(word)
    val backWord:Word = template.findOne(word.id,classOf[Word])
    logger.info(word.text.equalsIgnoreCase(backWord.text).toString)
  }
}

的applicationContext-的test.xml

更新

我解决了！

问题是scalaversión，我使用的是2.10，但它必须是2.9.2

spring-data-neo4j - 创建名为'neo4jTemplate'的bean时出错
