启用Spring数据源仅用于一个测试。

Enable spring datasource only for ONE test

问题

以下是翻译好的部分：

我有一个非常庞大的项目，其中一个类中只有3个测试使用了数据源连接，而这个连接是可选的，因此我只想在这个测试中通过Spring启用数据源连接。

在查找Spring手册时，我看到了在@SpringBootTest中使用properties = {}选项可以启用一些属性，我想在这里启用，

@SpringBootTest(classes = Application.class, webEnvironment = WebEnvironment.RANDOM_PORT, properties = {
    "spring.datasource.url=
",
    "spring.datasource.username=[user]",
    "spring.datasource.password=
		

			
输入密码查看隐藏内容

			

				
				
			

		
",
    "spring.jpa.database-platform = org.hibernate.dialect.PostgreSQLDialect",
    "hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect",
    "spring.jpa.database=postgresql"})

但是当我使用mvn clean install运行测试时，其他测试返回了以下错误;

org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (the profiles "test" are currently active).
...

有什么帮助吗？

英文:

I have a project so big in which only 3 tests in a class uses a datasource connection, and this connection is optional, so I am interested in only enable the datasource connection by spring in this test.

Looking for the Spring manual I see the option properties = {} in @SpringBootTest to enable some properties and I thought to enable here,

@SpringBootTest(classes = Application.class, webEnvironment = WebEnvironment.RANDOM_PORT, properties = {
    "spring.datasource.url=
",
    "spring.datasource.username=[user]",
    "spring.datasource.password=

",
    "spring.jpa.database-platform = org.hibernate.dialect.PostgreSQLDialect",
    "hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect",
    "spring.jpa.database=postgresql"})

But when I execute the tests with mvn clean install, in others test it returns me the error;

org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (the profiles "test" are currently active).

Any help?

我找到并适用于我的解决方案是在应用程序属性中排除2个自动配置类，

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration,org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration

因为在我的情况下，我不想在应用程序的其余部分连接数据库，并且在我想要连接数据库的测试中，我添加了以下属性以使用"profile"数据库运行此测试，并在注释@SpringBootTest中添加了以下属性，

@ActiveProfiles("database")
@SpringBootTest(classes = Application.class, webEnvironment = WebEnvironment.RANDOM_PORT, properties = {
    "spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration",
    "spring.datasource.url=
",
    "spring.datasource.username=[username]",
    "spring.datasource.password=

",
    "spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect",
    "hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect",
    "spring.jpa.database=postgresql",
    "spring.datasource.driver-class-name=org.postgresql.Driver"
})

在我想要测试的类中，我有一个使用@Autowired注解的EntityManagerFactory，位于@Component类内部。因此，当Spring尝试构建应用程序的所有组件以避免数据库未启用时可能发生的失败时，我将其标记为

@Autowired(required = false)

此外，为了创建连接的Bean，我创建了一个仅在启用"profile"数据库的情况下创建DataSource的Bean，正如我之前在测试中设置的那样，

@Bean
@Profile("database")
public DataSource dataSourceProfile(Environment env)
{
  return DataSourceBuilder.create().url(env.getProperty("spring.datasource.url"))
                            .driverClassName(env.getProperty("spring.datasource.driver-class-name"))
                            .password(env.getProperty("spring.datasource.password"))
                            .username(env.getProperty("spring.datasource.username")).build();
}

因此，通过这个配置，只有这个测试尝试与数据库连接，其余的测试不尝试连接。

英文:

The solution that I found and works for me it's to exclude for in the application properties 2 autoconfigures classes,

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration,org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration

because in my case, I don't want to connect the database in the rest of the application, and in the test that I want to connect the database I added to run this test with the profile "database" and the following properties in the annotation @SpringBootTest,

@ActiveProfiles("database")
@SpringBootTest(classes = Application.class, webEnvironment = WebEnvironment.RANDOM_PORT, properties = {
"spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration",
"spring.datasource.url=
",
"spring.datasource.username=[username]",
"spring.datasource.password=



输入密码查看隐藏内容








",
"spring.jpa.database-platform = org.hibernate.dialect.PostgreSQLDialect",
"hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect",
"spring.jpa.database=postgresql",
"spring.datasource.driver-class-name = org.postgresql.Driver"})

and in the class that I want to test I have an EntityManagerFactory annotated with @Autowired, inside a @Component class. So when Spring tries to construct all the Components of the application to avoid a failure that can occur here if the databases are not enabled, I put

@Autowired(required = false)

Also, to create the bean of the connection I created a bean to create a DataSource only if the profile "database" is enabled, as I put before in the test to run that test with the profile "database",

@Bean
@Profile("database")
public DataSource dataSourceProfile(Environment env)
{
return DataSourceBuilder.create().url(env.getProperty("spring.datasource.url"))
.driverClassName(env.getProperty("spring.datasource.driver-class-name"))
.password(env.getProperty("spring.datasource.password"))
.username(env.getProperty("spring.datasource.username")).build();
}

So with this configuration, only this test tries to connect with the database and the rest of the test doesn't try.
