我正在使用JPA开发Spring Boot项目，并希望使用Hibernate Search（API）来搜索全文查询。编译代码时没有错误，但是当我向实体类添加注释以启用全文搜索功能并运行代码时，我收到以下错误：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

这是我的POJO和JPA / Hibernate注释：
import org.hibernate.search.annotations.*;
import javax.persistence.*;
import java.io.Serializable;
import java.util.Objects;
@Entity
@Table(name="products")
@Indexed
public class Product implements Serializable{
/** int value that represents the id of the product */
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;
/** String value that represents the brandname */
@Field
private String brand;
/** String value that represents the model */
@Field
private String model;
/** String value that represents the sku */
@Field
private String sku;
public Product() {
}
public Product(String brand, String model, String sku) {
this.brand = brand;
this.model = model;
this.sku = sku;
}
/** GETTERS AND SETTERS */
}
我还在application.properties文件中添加了这两行：
spring.jpa.properties.hibernate.search.default.directory_provider = filesystem
spring.jpa.properties.hibernate.search.default.indexBase = /data/index/default
有人可以帮我解决这个问题吗？提前谢谢！
答案 0 :(得分：3)
有趣的错误是这个： 无法创建索引目录：/ data / index / default for index com.jdh.pilih2.domain.Product
您的Java应用程序需要具有在/ data / index / default中创建新目录的权限（如果缺少该目录，甚至需要创建该目录）。
我怀疑情况并非如此，因此无法正确初始化Hibernate Search。
