当我尝试使用方法[1]插入(增加或插入)文档时,我不时会收到此错误[2].

public NGram save(final NGram ngram) {
Criteria cr = where("_id").is(ngram.getNgram())
.and("f3c").is(ngram.getF3c())
.and("tokCount").is(ngram.getTokCount())

cr.and("second").is(ngram.getSecond());
}
if( ngram.getTokCount() > 2 ) {
cr.and("third").is(ngram.getThird());
}
final Query qry = new Query( cr );
final Update updt = new Update().inc("count", ngram.getCount());
template.upsert(qry, updt, NGram.class);
return ngram;
}

在包中com.x.record.persistence.impl我有一个需要存储库的组件com.x.record.persistence.repo.
这适用于spring-data-mongodb 1.5.2版.RELEASE
如果我升级到大于1.6.0的任何版本.RELEASE(我试过1.6.2和1.7.0)这不再有效.好像mongo存储库扫描不起作用,我收到错误:
org.springframework.beans.factory.BeanCreationException:

我有这个spring配置配置:

这会产生以下异常:
Caused by: java.lang.ClassNotFoundException: org.neo4j.kernel.impl.nioneo.store.StoreId
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1324)
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1177)
查看代码清楚地表明:SDN指的是在2.2.x中消除的neo4j库中的一个类:
org.neo4j.kernel.impl.nioneo.store.StoreId
在这种情况下我有什么选择？
在 mongo 控制台中，我有：
