java - @indexedEmbedded 的 includePaths 属性在放置在嵌套实例字段上时不会创建索引

Question

使用以下版本进行 hibernate 搜索:

• hibernate-core-4.2.0.Final.jar
• hibernate-search-engine-4.4.2.Final.jar
• hibernate-search-analyzers-3.3.0.Final.jar
• hibernate-search-orm-4.4.2.Final.jar
• lucene-core-3.6.2.jar

在放置实例的实例时，我遇到了 @indexedEmbedded 注释的 includePaths 属性问题。例如:(假设所有字段都有适当的 getter/setter)

根类:

@Indexed
public class RootClass {

@IndexedEmbedded
private Set<Instance> setOfInstances;

}

实例类:

public class Instance {

@Field(index = Index.YES, analyze = Analyze.YES, norms = Norms.NO, store = Store.NO)
private String name;

@Field(index = Index.YES, analyze = Analyze.YES, norms = Norms.NO, store = Store.NO)
private String vesion;

@IndexedEmbedded(includePaths={"type", "location", "users.name", "users.country"})
private InstanceDetail deltail;
}

InstanceDetail 类:

public class InstanceDetail{

@Field(index = Index.YES, analyze = Analyze.YES, norms = Norms.NO, store = Store.NO)
private int type;

@Field(index = Index.YES, analyze = Analyze.YES, norms = Norms.NO, store = Store.NO)
private String location;

@IndexedEmbedded
private Set<User> users;

@Field(index = Index.YES, analyze = Analyze.YES, norms = Norms.NO, store = Store.NO)
private String ref1;

@Field(index = Index.YES, analyze = Analyze.YES, norms = Norms.NO, store = Store.NO)
private String ref2

@IndexedEmbedded
private Set<Area> usersArea;
}

用户类别:

public class User{
    @Field(index = Index.YES, analyze = Analyze.YES, norms = Norms.NO, store = Store.NO)
    private String name;

    @Field(index = Index.YES, analyze = Analyze.YES, norms = Norms.NO, store = Store.NO)
    private String address;

    @Field(index = Index.YES, analyze = Analyze.YES, norms = Norms.NO, store = Store.NO)
    private String mobile;

    @Field(index = Index.YES, analyze = Analyze.YES, norms = Norms.NO, store = Store.NO)
    private String country;
}

因此，当我在 InstanceDetail 上定义 IndexedEmbedded 注释的 includePaths 属性时Instance，然后 InstanceDetail 的 NO 字段(其他字段如 name/vesion)正在为 RootClass 对象建立索引。 (通过日志确认)。没有任何异常(exception)。

所以这是按照 HibernateSearch 的设计或我的实现中磨损的东西。

它应该可以工作，但您可能会遇到与 https://hibernate.atlassian.net/browse/HSEARCH-1112 相关的错误
