我尝试使用属性创建一个名为Neo4jPoint的类 @Indexed（indexType = IndexType.POINT，indexName =“geolocation” 字符串wkt;
当我运行junit测试用例时，遇到以下情况：
java.lang.IllegalArgumentException: No index provider 'spatial' found. Maybe the intended provider (or one more of its dependencies) aren't on the classpath or it failed to load.

我使用的是spring-data-neo4j 2.2.2.RELEASE
我在这里缺少什么？我试图遵循“迈克尔·亨格的良好关系”，但在空间部分迷失了......
非常感谢提前 大卫

您必须提供neo4j-spatial依赖项，因为它不包含在SDN或Neo4j中。
