Question

我定义了以下实体：

@Entity
@Table(name = "EmailTemplate")
public class EmailTemplate {

尽管有表格注释，但我收到了java.sql.SQLException: Invalid object name 'email_template'。如何防止将诸如EmailTemplate之类的实体类转换为email_template表名？

编辑：

我正在使用Spring Boot：启动JPA。从我的build.gradle文件

compile("org.springframework.boot:spring-boot-starter-data-jpa")

Answer 1

Spring默认使用org.springframework.boot.orm.jpa.SpringNamingStrategy，它使用下划线分割驼峰案例名称。尝试在spring.jpa.hibernate.naming-strategy=org.hibernate.cfg.EJB3NamingStrategy中设置application.properties。查看this和this了解详情。

Answer 2

hibernate v5 ：

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

Answer 3

对于 Spring Boot 2 （已通过2.2.6.RELEASE选中），它应该是配置yml文件：

spring
  jpa:
    hibernate:
      naming:
        physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

所以您可以使用以下模型：

@Table(name = "tblDepartments")
public class Department {
    @Id
    @Column(name = "dpID")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;

    @NotEmpty
    @Size(min = 1, max = 25)
    @Column(name = "dpName", length = 25)
    private String name;

，并在启动时使用data.sql填充表：

INSERT INTO tblDepartments (dpName) VALUES ('Gryffindor');
INSERT INTO tblDepartments (dpName) VALUES ('Hufflepuff');

Answer 4

在您的appplication.properties.

中使用它

spring.jpa.hibernate.naming.physical-strategy=
org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

spring.jpa.hibernate.naming.implicit-strategy=
org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyJpaImpl

Answer 5

使用

spring.jpa.hibernate.naming-strategy=org.hibernate.cfg.DefaultNamingStrategy

Answer 6

在application.properties组中

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

Answer 7

已解决。

无效的对象名称：带有JPA（SQL服务器）的Springboot

在application.yaml / properties中指定

spring.jpa.hibernate.naming.implicit-strategy spring.jpa.hibernate.naming.physical-strategy

jpa： show-sql：错误休眠： ddl-auto：none＃不处于嵌入式模式时默认为“ none” 命名：隐式策略：org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyJpaImpl 物理策略：org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

Answer 8

org.springframework.dao.InvalidDataAccessResourceUsageException: could not execute statement; SQL [n/a];     
nested exception is org.hibernate.exception.SQLGrammarException: could not execute statement

两者都是必需的：

implicit-strategy 
physical-strategy

实体类名称转换为带有下划线的SQL表名称
