H2 Database Auto Configuration

Time：07-31

I am not sure what is happening with my H2 Database right now.

I was expecting to have my database auto configured when it does not exist yet (with all the tables and stuff) but i always got this exception.

Here is my User.java entity

import javax.persistence.GenerationType;

import javax.persistence.OneToMany;
import javax.persistence.Table;

import lombok.AllArgsConstructor;

import lombok.NoArgsConstructor;

@Entity
@Data
@NoArgsConstructor
@AllArgsConstructor
@Builder
@Table(name = "user")
public class User {


    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE)
    @Column(name = "user_id")
    private Long id;
    
    @Column(name = "name")
    private String name;
    
    @OneToMany(mappedBy = "user", cascade = CascadeType.ALL)
    private List<CashFlow> cashFlows;
    
    
    public void addCashFlow(CashFlow flow) {
        if (cashFlows == null) {
            cashFlows = new ArrayList<CashFlow>();
        }
        
        cashFlows.add(flow);
    }
    
    public void removeCashFlow(CashFlow flow) {
        cashFlows.removeIf((e) -> e.getId() == flow.getId());
    }
}

here is my properties file

spring.datasource.url=jdbc:h2:file:~/spring-boot-h2-db
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=password
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.jpa.hibernate.ddl-auto=update
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

So my question is that given the configuration above, why is it not working? can't understand the error Syntax error in SQL statement "create table [*]user (user_id bigint not null, name varchar(255), primary key (user_id))"; expected "identifier"; SQL statement:? What identifier is it looking for? i have already @Id declared on entity.

CodePudding user response：

'user' is a reserved keyword in H2.

You need to quote it or force quotation of all identifiers in configuration of Hibernate ORM.

You can also add ;NON_KEYWORDS=USER to JDBC URL as a workaround.
