JPA大写表名

Question

我在Postgresql中有一个表:

CREATE TABLE "UTILISATEUR"(

 "IdUtilisateur" serial NOT NULL,
 "Nom" character varying(50),
 "Prenom" character varying(50),
 "Profil" character varying(50),
 "Pseudo" character varying(20),
 "IdSite" integer DEFAULT 0,
 "Password" character varying(1024),
  id_role integer,
  )

我在这张桌子上尝试Map所以我使用了@TableJPA注释(见下文).这是我的application.propreties:

spring.datasource.url = jdbc:postgresql://localhost/baseecu
spring.datasource.username = postgres
spring.datasource.password =root
spring.datasource.driverClassName=org.postgresql.Driver
spring.jpa.database = MYSQL 
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto=update 
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect

最后这是我的实体类:

@Entity
@Table(name="UTILISATEUR")
public class Utilisateur   {
@Id
@GeneratedValue(strategy=GenerationType.AUTO) 
@Column(name="IdUtilisateur")
public Long id ;
public String Nom ; 
public String Prenom ; 
public String Profil ; 
public String Pseudo ; 


public String Password ;
@ManyToOne
@JoinColumn(name="id_role")
public Role role ;
public Long getId() {
    return id;

如果我有这样的话,@Table(name="UTILISATEUR")我会从PostgreSQL获得消息

ERREUR: la relation « utilisateur » n'existe pas 

当我试图逃避报价 @Table(name="\"UTILISATEUR\"")

ERROR: syntax error at or near "`"

我试过这个问题的回答,但它不起作用

Spring引用JPA在TABLE中插入大写名称和Hibernate

更新

我一直在搜索ImprovedNamingstrategy它似乎是一个问题在春季启动而不是我使用EJB3NamingStrategy和DefaultNamingStrategy它不起作用,当Hibernate执行SQL时结果很混乱:

Hibernate: select utilisateu0_.IdUtilisateur as IdUtilis1_2_, utilisateu0_.Nom as Nom2_2_, utilisateu0_.Password as Password3_2_, utilisateu0_.Prenom as Prenom4_2_, utilisateu0_.Profil as Profil5_2_, utilisateu0_.Pseudo as Pseudo6_2_, utilisateu0_.id_role as id_role7_2_ from UTILISATEUR utilisateu0_ 

就像它知道表名是UPPERCASE但不想映射或我不知道它有什么问题这是使用的结果

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

以及EJB3NamingStrategy

当我使用这样的注释时,这也是结果

@Table(name="UTILISATEUR")  

我也是这样尝试过的

@Table(name="\"UTILISATEUR\"")

我得到了这个问题

ERROR: syntax error at or near "`"

Hibernate: select utilisateu0_.IdUtilisateur as IdUtilis1_2_, utilisateu0_.Nom as Nom2_2_, utilisateu0_.Password as Password3_2_, utilisateu0_.Prenom as Prenom4_2_, utilisateu0_.Profil as Profil5_2_, utilisateu0_.Pseudo as Pseudo6_2_, utilisateu0_.id_role as id_role7_2_ from `UTILISATEUR` utilisateu0_ 

最后这是我的 pom.xml

Answer 1

也许是因为你正在使用MYSQL5DIALECT,有一个Postgres方言就像这样使用post it和改进的命名策略使用EJB3像Spring引用 JPA插入TABLE中的大写名称和Hibernate

spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect

希望这对你有用

Answer 2

我在postgres 8.4和hibernate 5.0.3中复制了你的UTILISATEUR表(删除了角色).

它按预期使用显式表和列名称注释:

@Entity(name="\"UTILISATEUR\"")
public class Utilisateur {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO) 
    @Column(name="\"IdUtilisateur\"")
    private Long id ;

    @Column(name="\"Nom\"")
    private String Nom ; 
    @Column(name="\"Prenom\"")
    private String Prenom ; 
    @Column(name="\"Profil\"")
    private String Profil ; 
    @Column(name="\"Pseudo\"")
    private String Pseudo ; 

    @Column(name="\"Password\"")
    private String Password ;

    ... getter / setters

}
