Ich versuche, eine Tabelle über Liquibase, Spring Boot Application und H2 -Datenbank zu erstellen ⇐ Java

[Anonymous]

Dies ist meine Migration < /p>




















< /code>
Und das ist mt db.changelog-master.xml < /p>



< /code>
Dies ist meine Entität < /p>
package ecommerce_app.ecom;

import jakarta.persistence.Column;
import jakarta.persistence.Entity;
import jakarta.persistence.GeneratedValue;
import jakarta.persistence.GenerationType;
import jakarta.persistence.Id;
import jakarta.persistence.Table;

import java.time.LocalDateTime;

@Entity
@Table(name = "users")
public class User {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

@Column(name = "username", nullable = false, unique = true)
private String username;

@Column(name = "password", nullable = false)
private String password;

@Column(name = "created_at", nullable = false, updatable = false)
private LocalDateTime createdAt;

// Constructors
public User() {}

public User(String username, String password) {
this.username = username;
this.password = password;
}

// Getters and Setters
public Long getId() {
return id;
}

public void setId(Long id) {
this.id = id;
}

public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username = username;
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public LocalDateTime getCreatedAt() {
return createdAt;
}

public void setCreatedAt(LocalDateTime createdAt) {
this.createdAt = createdAt;
}
}

< /code>
Und dies ist meine Liquibase -Konfigurationsdatei < /p>
package ecommerce_app.ecom;

import com.zaxxer.hikari.HikariConfig;
import com.zaxxer.hikari.HikariDataSource;
import liquibase.integration.spring.SpringLiquibase;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;

import jakarta.annotation.PostConstruct;

import javax.sql.DataSource;

@Configuration
public class LiquibaseConfig {

@Bean
@Primary
public DataSource dataSource() {
HikariConfig hikariConfig = new HikariConfig();
hikariConfig.setJdbcUrl("jdbc:h2:mem:ecomdb");
hikariConfig.setUsername("sa");
hikariConfig.setPassword("k6oS3aLoR4tbL3wsgRfEXRIdb6GzSulMcg6adLV6TOQ");
hikariConfig.setDriverClassName("org.h2.Driver");

hikariConfig.setMaximumPoolSize(10);
hikariConfig.setMinimumIdle(5);

return new HikariDataSource(hikariConfig);
}

@Bean
public SpringLiquibase liquibase(DataSource dataSource) {
SpringLiquibase liquibase = new SpringLiquibase();
liquibase.setDataSource(dataSource);
liquibase.setChangeLog("classpath:db/changelog/db.changelog-master.xml");
return liquibase;
}

@PostConstruct
public void initLiquibase() {
SpringLiquibase liquibase = liquibase(dataSource());
try {
liquibase.afterPropertiesSet();
} catch (Exception e) {
e.printStackTrace();
}
}
}

Ich versuche, es über Chat -GPT zu beheben, aber der Vorschlag funktioniert nicht für mich. Ich habe Erfahrung mit Liquibase -Migrationen, aber nicht mit dem Setup. Bitte helfen Sie
