Spring 启动 + Hibernate 搜索：无法构建 Hibernate SessionFactory
Spring Boot + Hibernate Search: Unable to build Hibernate SessionFactory
我正在使用 JPA 开发一个 Spring 启动项目，并希望使用 Hibernate Search (API) 来搜索全文查询。当我编译代码时没有错误，但是当我向我的实体类添加注释以启用全文搜索功能和 运行 代码时，我收到以下错误：

这是我的带有 JPA/Hibernate 注释的 POJO：
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？提前致谢！
有趣的错误是这个：
无法创建索引目录：索引 com.jdh.pilih2.domain.Product
的 /data/index/default
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，甚至可以创建该目录）。
我怀疑情况并非如此，因此无法正确初始化 Hibernate Search。
我正在使用 JPA 开发一个 Spring 启动项目，并希望使用 Hibernate Search (API) 来搜索全文查询。当我编译代码时没有错误，但是当我向我的实体类添加注释以启用全文搜索功能和 运行 代码时，我收到以下错误：

这是我的带有 JPA/Hibernate 注释的 POJO：
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？提前致谢！
有趣的错误是这个： 无法创建索引目录：索引 com.jdh.pilih2.domain.Product
的 /data/index/default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，甚至可以创建该目录）。
我怀疑情况并非如此，因此无法正确初始化 Hibernate Search。
