Spring测试:为org.springframework.test.context.jdbc.Sql配置数据源

Question

在我的Spring Boot项目中，我有两个数据源：

@Primary
@Bean(name = "pgDatasource")
public BasicDataSource dataSource() {
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName(env.getProperty("spring.datasource.dbcp2.driver-class-name"));
dataSource.setUrl(env.getProperty("spring.datasource.dbcp2.url"));
dataSource.setUsername(env.getProperty("spring.datasource.dbcp2.username"));
dataSource.setPassword(env.getProperty("spring.datasource.dbcp2.password"));
dataSource.setMaxActive(Integer.valueOf(env.getProperty("spring.datasource.dbcp2.max-total")));
dataSource.setMaxIdle(Integer.valueOf(env.getProperty("spring.datasource.dbcp2.max-idle")));
dataSource.setInitialSize(Integer.valueOf(env.getProperty("spring.datasource.dbcp2.initial-size")));
return dataSource;
}
@Bean(name = "h2Datasource")
public BasicDataSource h2DataSource() {
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName(env.getProperty("spring.h2.datasource.driver-class-name"));
dataSource.setUrl(env.getProperty("spring.h2.datasource.url"));
dataSource.setUsername(env.getProperty("spring.h2.datasource.username"));
dataSource.setPassword(env.getProperty("spring.h2.datasource.password"));
Resource initData = new ClassPathResource("scripts/inmem.sql");
DatabasePopulator databasePopulator = new ResourceDatabasePopulator(initData);
DatabasePopulatorUtils.execute(databasePopulator, dataSource);
return dataSource;
}

这里PostgreSQL的数据源是一个主bean。在我的几个测试中，我想针对h2数据库运行一个脚本。为此，我尝试使用@Sql注释。不过，若我使用@Sql，它会针对pgDatasource运行脚本。我可以将h2配置为这些测试的主bean，但测试方法的主体取决于pgDatasource是主bean的配置。

测试样本：

@Test
@Sql(scripts = "/clean_login_attempts.sql", executionPhase = AFTER_TEST_METHOD)
void loginAttemptsIncrementTheCount() throws Exception {
unsuccessfulLoginRequest();
unsuccessfulLoginRequest();
unsuccessfulLoginRequest();
LoginAttempt loginAttempt = loginAttemptService.getAttempt("admin");
assertEquals(3, loginAttempt.getAttempt());
}

是否可以为org.springframework.test.context.jdbc.Sql注释配置数据源？

Answer 1

添加

config = @SqlConfig(dataSource = "h2Datasource", transactionManager = "h2tx") 

解决了这个问题。

@Test
@Sql(scripts = "/clean_login_attempts.sql", 
executionPhase = AFTER_TEST_METHOD, 
config = @SqlConfig(dataSource = "h2Datasource", transactionManager = "h2tx"))
void loginAttemptsIncrementTheCount() throws Exception {
unsuccessfulLoginRequest();
unsuccessfulLoginRequest();
unsuccessfulLoginRequest();
LoginAttempt loginAttempt = loginAttemptService.getAttempt("admin");
assertEquals(3, loginAttempt.getAttempt());
}
