为什么 HSQLDB 和 Spring Data JDBC 声称我的 table 不存在？
Why does HSQLDB and Spring Data JDBC claim my table does not exist?
我 post 几天前就同一问题编辑了一些类似的东西，但现在我想我（在一些对 post 发表评论的人的帮助下）将它缩小到确切地知道我需要什么帮助。我正在尝试在我的应用程序中使用 Spring 数据 JDBC 和 HSQLDB（我没有尝试使用 Web 服务器）。但是驱动程序不支持 get/set 连接超时。因此，我什至无法使用数据库。

这是 schema.sql 文件：
CREATE TABLE Students (
id INTEGER IDENTITY PRIMARY KEY,
fName VARCHAR(50),
lName VARCHAR(50),
rank VARCHAR(50)
);
这是 application.properties 文件：
logging.level.sql=debug
spring.datasource.generate-unique-name=false
这里是主要的class:
package com.example.demo;
import org.springframework.boot.ApplicationRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
@SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
@Bean
ApplicationRunner applicationRunner(StudentRepo studentRepo) {
return args -> {
var s1 = Student.createStudent("John", "Doe");
s1.setId(1l);
var s2 = Student.createStudent("Jane", "Doe");
s2.setId(2l);
System.out.println(studentRepo.save(s1));
System.out.println(studentRepo.save(s2));
System.out.println(studentRepo.findByFName("John"));
};
}
}
这是 StudentRepo 界面：
package com.example.demo;
import org.springframework.data.jdbc.repository.query.Query;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;
import org.springframework.stereotype.Repository;
import java.util.List;
@Repository
public interface StudentRepo extends CrudRepository<Student, Long> {
@Query("SELECT * FROM Students WHERE fName = :name")
List<Student> findByFName(@Param("name") String fName);
}
这是 INFO 日志语句：

所以在尝试重现并使其工作之后，我可以通过以下更改完成它：
在schema.sql中：
CREATE TABLE "Student"
(
"id" INTEGER GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
"fName" VARCHAR(50),
"lName" VARCHAR(50),
"rank" VARCHAR(50)
);
第一个更改是删除 Student 末尾的 s，第二个更改是使 id 列自动生成。我还为所有名称添加了双引号，以便 HSQLDB 在这里使用不区分大小写。
在学生中class:
@Data
@Table("Student")
public class Student {
@Id
@Column("id")
private long id;
@Column("fName")
private String fName;
@Column("lName")
private String lName;
@Column("rank")
private String rank;
}
基本上我指定了列和 table 名称，否则 Spring 数据将使用默认命名策略，例如使用下划线转换驼峰式字段名称（例如，对于字段名称 fName，映射的列名称将是 F_NAME）。
我还在 Id 字段中添加了 Id 注释，以便 Spring Data 可以正确处理检查是否为新实体（基于 Spring Data 将使用 Insert 或 Update 语句）。如果没有该注释，您将不得不实现另一个接口来提供该功能（我在这里找到了一个解释：https://prog.world/how-spring-data-jdbc-determines-when-an-object-is-new/）
在 StudentRepo 中：
public interface StudentRepo extends CrudRepository<Student, Long> {
@Query("SELECT * FROM \"Student\" WHERE \"fName\" = :name")
List<Student> findByFName(@Param("name") String fName);
}
我这里也去掉了table名字的后缀s，加了双引号
如何让它发挥作用。我试着解释一下为什么它有效，这也允许其他解决方案。
首先要意识到的是 Spring Data JDBC 在它生成的语句中引用了所有 table 和列名。
这有两个作用：
它允许 user 和 order 和 spaces in names 这样的名称。前两个通常被禁止，因为它们是关键字，第三个因为它包含空格。
这也使名称区分大小写。
您通常不必担心这一点，只要您使用 Spring Data JDBC 的生成名称，因为它们使用数据库默认使用的任何字母大小写。 SQL 标准说这应该是大写，但我们都知道数据库供应商对 SQL 标准的看法。
如果您在 @Column 或 @Table 注释中指定名称，则会逐字使用该名称。因此 @Table("Student") is different from @Table("student") 和 @Table("STUDENT") 以及您的模式创建脚本必须完全匹配。因此，您必须使用数据库使用的默认字母大小写，或者必须在脚本中使用引号，包括注释中的自定义查询。
我 post 几天前就同一问题编辑了一些类似的东西，但现在我想我（在一些对 post 发表评论的人的帮助下）将它缩小到确切地知道我需要什么帮助。我正在尝试在我的应用程序中使用 Spring 数据 JDBC 和 HSQLDB（我没有尝试使用 Web 服务器）。但是驱动程序不支持 get/set 连接超时。因此，我什至无法使用数据库。

这是 schema.sql 文件：
CREATE TABLE Students (
id INTEGER IDENTITY PRIMARY KEY,
fName VARCHAR(50),
lName VARCHAR(50),
rank VARCHAR(50)
);
这是 application.properties 文件：
logging.level.sql=debug
spring.datasource.generate-unique-name=false
这里是主要的class:
package com.example.demo;
import org.springframework.boot.ApplicationRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
@SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
@Bean
ApplicationRunner applicationRunner(StudentRepo studentRepo) {
return args -> {
var s1 = Student.createStudent("John", "Doe");
s1.setId(1l);
var s2 = Student.createStudent("Jane", "Doe");
s2.setId(2l);
System.out.println(studentRepo.save(s1));
System.out.println(studentRepo.save(s2));
System.out.println(studentRepo.findByFName("John"));
};
}
}
这是 StudentRepo 界面：
package com.example.demo;
import org.springframework.data.jdbc.repository.query.Query;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;
import org.springframework.stereotype.Repository;
import java.util.List;
@Repository
public interface StudentRepo extends CrudRepository<Student, Long> {
@Query("SELECT * FROM Students WHERE fName = :name")
List<Student> findByFName(@Param("name") String fName);
}
这是 INFO 日志语句：

所以在尝试重现并使其工作之后，我可以通过以下更改完成它：
在schema.sql中：
CREATE TABLE "Student"
(
"id" INTEGER GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
"fName" VARCHAR(50),
"lName" VARCHAR(50),
"rank" VARCHAR(50)
);
第一个更改是删除 Student 末尾的 s，第二个更改是使 id 列自动生成。我还为所有名称添加了双引号，以便 HSQLDB 在这里使用不区分大小写。
在学生中class:
@Data
@Table("Student")
public class Student {
@Id
@Column("id")
private long id;
@Column("fName")
private String fName;
@Column("lName")
private String lName;
@Column("rank")
private String rank;
}
基本上我指定了列和 table 名称，否则 Spring 数据将使用默认命名策略，例如使用下划线转换驼峰式字段名称（例如，对于字段名称 fName，映射的列名称将是 F_NAME）。
我还在 Id 字段中添加了 Id 注释，以便 Spring Data 可以正确处理检查是否为新实体（基于 Spring Data 将使用 Insert 或 Update 语句）。如果没有该注释，您将不得不实现另一个接口来提供该功能（我在这里找到了一个解释：https://prog.world/how-spring-data-jdbc-determines-when-an-object-is-new/）
在 StudentRepo 中：
public interface StudentRepo extends CrudRepository<Student, Long> {
@Query("SELECT * FROM \"Student\" WHERE \"fName\" = :name")
List<Student> findByFName(@Param("name") String fName);
}
我这里也去掉了table名字的后缀s，加了双引号
首先要意识到的是 Spring Data JDBC 在它生成的语句中引用了所有 table 和列名。 这有两个作用：
它允许
user和order和spaces in names这样的名称。前两个通常被禁止，因为它们是关键字，第三个因为它包含空格。这也使名称区分大小写。 您通常不必担心这一点，只要您使用 Spring Data JDBC 的生成名称，因为它们使用数据库默认使用的任何字母大小写。 SQL 标准说这应该是大写，但我们都知道数据库供应商对 SQL 标准的看法。
如果您在 @Column 或 @Table 注释中指定名称，则会逐字使用该名称。因此 @Table("Student") is different from @Table("student") 和 @Table("STUDENT") 以及您的模式创建脚本必须完全匹配。因此，您必须使用数据库使用的默认字母大小写，或者必须在脚本中使用引号，包括注释中的自定义查询。
