我正在尝试使用Spring Boot 2.0.3版连接两个不同的数据源。一种是指向MySQL，另一种是PostgreSQL。 MySQL通过了所有测试。但是PostgreSQL有问题。
这里是应映射到PostgreSQL的Entity类。
@Entity
@Table(name = "order")
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Order {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String productName;
}
这是PostgreSQL的配置类。
@Configuration
@EnableJpaRepositories(
basePackageClasses = Order.class,
entityManagerFactoryRef = "orderEntityManager",
transactionManagerRef = "orderTransactionManager"
)
@PropertySource("classpath:application.properties")
public class OrderConfig {
@Autowired
Environment env;
@Bean
public DataSource getDataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(env.getProperty("order.datasource.class"));
dataSource.setUrl(env.getProperty("order.datasource.url"));
dataSource.setUsername(env.getProperty("order.datasource.username"));
dataSource.setPassword(env.getProperty("order.datasource.password"));
return dataSource;
}
@Bean(name = "orderEntityManager")
public LocalContainerEntityManagerFactoryBean getEntityManager() {
LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean =
new LocalContainerEntityManagerFactoryBean();
localContainerEntityManagerFactoryBean.setDataSource(this.getDataSource());
localContainerEntityManagerFactoryBean.setPackagesToScan("com.seal.multipledatasource.entity.order");
HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();
localContainerEntityManagerFactoryBean.setJpaVendorAdapter(hibernateJpaVendorAdapter);
Map<String, String> properties = new HashMap<>();
properties.put("hibernate.hbm2ddl.auto", env.getProperty("order.jpa.hibernate.ddl-auto"));
properties.put("hibernate.dialect", env.getProperty("order.jpa.hibernate.dialect"));
localContainerEntityManagerFactoryBean.setJpaPropertyMap(properties);
return localContainerEntityManagerFactoryBean;
}
@Bean(name = "orderTransactionManager")
public PlatformTransactionManager getTransactionManager() {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(getEntityManager().getObject());
return transactionManager;
}
}
Spring数据存储库。
@Repository
public interface OrderRepo extends JpaRepository<Order, Long>{
}
测试类
@RunWith(SpringRunner.class)
@ContextConfiguration(classes = OrderConfig.class)
public class OrderRepoTest {
@Autowired
private OrderRepo orderRepo;
@Test
@Transactional
public void testOrderRepo() {
Order order = orderRepo.save(new Order(null, "ACT LITE"));
Assertions.assertThat(order).isNotNull();
Assertions.assertThat(order.getId()).isNotZero();
}
}

==更新==
我已经通过MySQL数据库的Order实体进行了测试。订单表会导致相同的oo错误
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near
也没有发现bean异常。
然后我重命名了实体类，SQL错误消失了。但是，对于OrderRepo bean，找不到bean的异常仍然存在。
答案 0 :(得分：3)
我看过您的日志，看来'order'关键字有问题：
由以下原因引起：org.postgresql.util.PSQLException：错误：“订单”处或附近的语法错误
也许这可以帮助您：Error: syntax error at or near 'order'
已更新：
正如我们在下面的评论中看到的那样，该问题导致对软件包的不良扫描。 Spring找不到存储库。
您应该拥有
@EnableJpaRepositories(basePackages = {
"com.seal.multipledatasource.repo"})
