我有一个Spring引导项目，从导入的jar中提取数据库配置，并尝试连接自己的数据库配置以进行第二次数据库连接。 jar中的第一个DB配置标有@Primary，第二个不是。
当我尝试启动项目时，我收到此错误。
Not a managed type: class test.example.MyEntity
在我的第一个数据库配置中，它正在寻找一个完全不同的包，我们称之为com.example.test，这是这样配置的：
@Configuration
@EnableTransactionManagement
@PropertySource(value = { "classpath:/${app.execution.environment}/application.properties" })
@EnableJpaRepositories(basePackages = "com.example.test", entityManagerFactoryRef = "mysqlEntityManager", transactionManagerRef = "mysqlTransactionManager")
public class MysqlHibernateConfig {
@Primary
@Bean
public LocalContainerEntityManagerFactoryBean mysqlEntityManager() {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(mysqlDataSource());
em.setPackagesToScan(new String[] { "com.example.test" });
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
em.setJpaVendorAdapter(vendorAdapter);
em.setJpaPropertyMap(hibernateProperties());
return em;
}
.... other relevant methods below for configuring DB
}
在我的第二个数据库配置中，我指向一个完全不同的实体包
@Configuration
@EnableTransactionManagement
@EntityScan(basePackages = { "test.example" })
@EnableJpaRepositories(entityManagerFactoryRef = "myEntityManager", transactionManagerRef = "myTransactionManager", basePackages = {
"test.example" })
public class MyRepositoryConfig {
@Bean
public LocalContainerEntityManagerFactoryBean myEntityManager() {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(vspnetDataSource());
em.setPackagesToScan(new String[] { "test.example" });
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
em.setJpaVendorAdapter(vendorAdapter);
em.setJpaPropertyMap(vspnetHibernateProperties());
return em;
}
}
我不明白为什么它不会找到并管理测试中的bean。例如，这些实体看起来像这样：
@Entity
@Table(name = "employee")
public class MyEntity {
// column fields
}
我的配置如下：
@Configuration
@ComponentScan(basePackages = {"com.example.test", "test.example"})
public class WebMvcConfig extends WebMvcConfigurerAdapter {
}
如何让spring正确管理这些bean并允许我使用这些实体？
我检查了所有托管bean，发现我的第二个实体经理出现了我的第一个，所以我知道他们正在接线。不知道为什么他们不会抓住正确的实体。
