由于提供整个系统的源代码不仅数量庞大，而且违反了Stack Overflow的原则，我将提供一个简化的示例，说明如何使用Spring Boot, JPA, Maven, jQuery和MySQL创建一个基本的进销存管理系统。
- 创建Maven项目并添加依赖
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
</dependencies>- 配置数据库和JPA
@Configuration
public class DatabaseConfig {
@Bean
public DataSource dataSource() {
EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
return builder.setType(EmbeddedDatabaseType.H2).build();
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, JpaVendorAdapter jpaVendorAdapter) {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSource);
em.setPackagesToScan("com.yourpackage.model");
em.setJpaVendorAdapter(jpaVendorAdapter);
em.setJpaProperties(additionalJpaProperties());
return em;
}
Properties additionalJpaProperties() {
Properties properties = new Properties();
properties.setProperty("hibernate.hbm2ddl.auto", "update");
properties.setProperty("hibernate.dialect", "org.hibernate.dialect.H2Dialect");
return properties;
}
}- 创建实体和Repository
@Entity
public class Product {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String name;
// getters and setters
}
public interface ProductRepository extends JpaRepository<Product, Long> {
}- 创建Service和Controller
@Service
public class ProductService {
@Autowired
private ProductRepository productRepository;
public List<Product> findAll() {
return productRepository.findAll();
}
}
@RestController
public class ProductController {
@Autowired
private ProductService productService;
