Question

我有一个小项目，我想与lucene和hibernate集成：这是bean文件： package com.domain.java;

 import javax.persistence.Entity;
  import javax.persistence.GeneratedValue;
   import javax.persistence.Id;

    import org.hibernate.search.annotations.Analyzer;
      import org.hibernate.search.annotations.DocumentId;
       import org.hibernate.search.annotations.Field;
      import org.hibernate.search.annotations.Indexed;
       import org.hibernate.search.annotations.Store;

     @Entity
     @Indexed
 @Analyzer(impl = org.apache.lucene.analysis.standard.StandardAnalyzer.class)

public class TempFile {
    @Field(store = Store.YES)
    private String iconName;

    @Field(store = Store.YES)
    private String name;

    @Id
    @DocumentId
    @Field(store = Store.YES)

    private String path;

    @Field(store = Store.YES)
    private boolean mightHaveThumbnail;

    @Field(store = Store.YES)
    private boolean folder;

    @Field(store = Store.YES)
    private boolean file;

    public String getIconName() {
        return iconName;
    }
    public String getName() {
        return name;
    }
    public String getPath() {
        return path;
    }
    public boolean isMightHaveThumbnail() {
        return mightHaveThumbnail;
    }
    public boolean isFolder() {
        return folder;
    }
    public boolean isFile() {
        return file;
    }
    public void setIconName(String iconName) {
        this.iconName = iconName;
    }
    public void setName(String name) {
        this.name = name;
    }
    public void setPath(String path) {
        this.path = path;
    }
    public void setMightHaveThumbnail(boolean mightHaveThumbnail) {
        this.mightHaveThumbnail = mightHaveThumbnail;
    }
    public void setFolder(boolean folder) {
        this.folder = folder;
    }
    public void setFile(boolean file) {
        this.file = file;
    }

}

这是Hibernate文件：

        Session session = sessionFactory.openSession();
        session.beginTransaction();

            // get the property value and print it out

            Enumeration<?> e = prop.propertyNames();
            while (e.hasMoreElements()) {
                String key = (String) e.nextElement();
                String value = prop.getProperty(key);
                System.out.println("Key : " + key + ", Value : " + value);
            }

        } catch (IOException ex) {

Answer 1

真正的问题在于： org.apache.lucene.index.IndexWriterConfig.setWriteLockTimeout（J）Lorg /阿帕奇/ lucene的/索引/ IndexWriterConfig;

您有依赖性问题：您使用的Lucene版本与您正在使用的Hibernate Search版本不兼容。

检查您的依赖项并修复它们，您的问题应该消失。

没有创建lucene搜索索引文件的hibernate：IndexWriterConfig.setWriteLockTimeout（J）Lorg / apache / lucene / index / IndexWriterConfig;
