Spring Data Neo4j java.lang.reflect.MalformedParameterizedTypeException

Question

我是 spring 数据 neeo4j 的新手。我正在尝试测试一个节点，但是当我运行测试时，发生了与 java.lang.reflect.MalformedParameterizedTypeException 相关的错误。

这是我的配置：

大陆.java

import org.springframework.data.neo4j.annotation.Indexed;
import org.springframework.data.neo4j.annotation.NodeEntity;
import org.springframework.data.neo4j.support.index.IndexType;
import org.springframework.roo.addon.javabean.RooJavaBean;

@NodeEntity
@RooJavaBean
public class Continent extends AbstractEntity {

    @Indexed(indexType = IndexType.FULLTEXT)
    private String code;
    @Indexed(indexType = IndexType.FULLTEXT)
    private String name;

}

ContinentRepository.java

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

import com.glx.partycore.domain.Continent;

public interface ContinentRepository extends GraphRepository<Continent>{

}

错误是：

看起来我的 neo4j 配置有任何问题，因为“节点”弹簧数据没有错误......我不知道可能是什么

Answer 1

项目终于开始运作了。我正在使用没有 spring roo 的相同代码，它的工作。 spring roo 似乎与 Spring Data Neo4j 有任何冲突。

我向 Spring Project 创建了一个问题。
