在Spring 4.1之前我们在准备测试数据时可能通过继承AbstractTransactionalJUnit4SpringContextTests,然后调用executeSqlScript()进行测试,其中存在一个主要问题:如果要同时执行多个数据源的初始化就靠不住了,而且使用起来也不是特别便利,Spring4.1提供了@Sql注解来完成这个任务。
1、初始化Spring配置:
<jdbc:embedded-database id="dataSource1" type="HSQL"/> <jdbc:embedded-database id="dataSource2" type="HSQL"/> <bean id="txManager1" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource1"/> </bean> <bean id="txManager2" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource2"/> </bean>
此处使用jdbc:embedded嵌入数据库来完成测试,数据库使用HSQL。
2、 方法级别的@Sql
@RunWith(SpringJUnit4ClassRunner.class) @FixMethodOrder(MethodSorters.NAME_ASCENDING) @ContextConfiguration(value = "classpath:spring-datasource.xml") @DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD) public class MethodLevelSqlTest { private JdbcTemplate jdbcTemplate1; private JdbcTemplate jdbcTemplate2; @Autowired @Qualifier("dataSource1") public void setDataSource1(DataSource dataSource1) { this.jdbcTemplate1 = new JdbcTemplate(dataSource1); } @Autowired @Qualifier("dataSource2") public void setDataSource2(DataSource dataSource2) { this.jdbcTemplate2 = new JdbcTemplate(dataSource2); } @Test @Sql(value = {"classpath:schema.sql", "classpath:init-data.sql", "classpath:updated-data.sql"}, config = @SqlConfig(encoding = "utf-8", separator = ";", commentPrefix = "--", dataSource = "dataSource1", transactionManager = "txManager1")) public void test01_simple() { Assert.assertEquals( Integer.valueOf(3), jdbcTemplate1.queryForObject("select count(1) from users", Integer.class)); } @Test @Sql(value = {"classpath:schema.sql", "classpath:init-data.sql"}, config = @SqlConfig(encoding = "utf-8", separator = ";", commentPrefix = "--", dataSource = "dataSource2", transactionManager = "txManager2")) public void test02_simple() { Assert.assertEquals( Integer.valueOf(2), jdbcTemplate2.queryForObject("select count(1) from users", Integer.class)); } }
方法级别的@Sql在每个方法上都会执行。其中@Sql可以指定多个sql文件,然后通过@SqlConfig指定其编码、分隔符、注释前缀、使用哪个数据源和事务管理器。
3、类级别的@Sql
@RunWith(SpringJUnit4ClassRunner.class) @FixMethodOrder(MethodSorters.NAME_ASCENDING) @ContextConfiguration(value = "classpath:spring-datasource.xml") @Sql(value = {"classpath:schema.sql", "classpath:init-data.sql", "classpath:updated-data.sql"}, config = @SqlConfig(encoding = "utf-8", separator = ";", commentPrefix = "--", dataSource = "dataSource1", transactionManager = "txManager1")) @DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD) public class ClassLevelSqlTest { private JdbcTemplate jdbcTemplate1; @Autowired @Qualifier("dataSource1") public void setDataSource1(DataSource dataSource1) { this.jdbcTemplate1 = new JdbcTemplate(dataSource1); } @Test public void test01_simple() { Assert.assertEquals( Integer.valueOf(3), jdbcTemplate1.queryForObject("select count(1) from users", Integer.class)); } }
类级别的对整个测试用例中的每个方法都起作用。
4、指定多个@Sql
Java8之前需要使用@SqlGroup,而Java8之后直接使用多个@Sql注解即可。
@RunWith(SpringJUnit4ClassRunner.class) @FixMethodOrder(MethodSorters.NAME_ASCENDING) @ContextConfiguration(value = "classpath:spring-datasource.xml") @Transactional() @SqlGroup( { @Sql(value = {"classpath:schema.sql", "classpath:init-data.sql", "classpath:updated-data.sql"}, config = @SqlConfig(encoding = "utf-8", separator = ";", commentPrefix = "--", dataSource = "dataSource1", transactionManager = "txManager1")), @Sql(value = {"classpath:schema.sql", "classpath:init-data.sql"}, config = @SqlConfig(encoding = "utf-8", separator = ";", commentPrefix = "--", dataSource = "dataSource2", transactionManager = "txManager2")) } ) @DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD) public class ClassLevelSqlGroupTest { private JdbcTemplate jdbcTemplate1; private JdbcTemplate jdbcTemplate2; @Autowired @Qualifier("dataSource1") public void setDataSource1(DataSource dataSource1) { this.jdbcTemplate1 = new JdbcTemplate(dataSource1); } @Autowired @Qualifier("dataSource2") public void setDataSource2(DataSource dataSource2) { this.jdbcTemplate2 = new JdbcTemplate(dataSource2); } @Test @Transactional() @Sql(value = {"classpath:schema.sql", "classpath:init-data.sql", "classpath:updated-data.sql"}, config = @SqlConfig(encoding = "utf-8", separator = ";", commentPrefix = "--", dataSource = "dataSource1", transactionManager = "txManager1")) public void test01_simple() { Assert.assertEquals( Integer.valueOf(3), jdbcTemplate1.queryForObject("select count(1) from users", Integer.class)); } @Test @Transactional() @Sql(value = {"classpath:schema.sql", "classpath:init-data.sql"}, config = @SqlConfig(encoding = "utf-8", separator = ";", commentPrefix = "--", dataSource = "dataSource2", transactionManager = "txManager2")) public void test02_simple() { Assert.assertEquals( Integer.valueOf(2), jdbcTemplate2.queryForObject("select count(1) from users", Integer.class)); } }
也可以通过元注解把注解合并:
@SqlGroup( { @Sql(value = {"classpath:schema.sql", "classpath:init-data.sql", "classpath:updated-data.sql"}, config = @SqlConfig(encoding = "utf-8", separator = ";", commentPrefix = "--", dataSource = "dataSource1", transactionManager = "txManager1")), @Sql(value = {"classpath:schema.sql", "classpath:init-data.sql"}, config = @SqlConfig(encoding = "utf-8", separator = ";", commentPrefix = "--", dataSource = "dataSource2", transactionManager = "txManager2")) } ) @Retention(RUNTIME) @Target(TYPE) @interface CompositeSqlGroup { }
直接使用@CompositeSqlGroup注解即可。
5、事务
@RunWith(SpringJUnit4ClassRunner.class) @FixMethodOrder(MethodSorters.NAME_ASCENDING) @ContextConfiguration(value = "classpath:spring-datasource.xml") @DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD) public class TransactionalTest { private JdbcTemplate jdbcTemplate1; private JdbcTemplate jdbcTemplate2; @Autowired @Qualifier("dataSource1") public void setDataSource1(DataSource dataSource1) { this.jdbcTemplate1 = new JdbcTemplate(dataSource1); } @Autowired @Qualifier("dataSource2") public void setDataSource2(DataSource dataSource2) { this.jdbcTemplate2 = new JdbcTemplate(dataSource2); } @Test @Transactional("txManager1") @Sql(value = {"classpath:schema.sql", "classpath:init-data.sql", "classpath:updated-data.sql"}, config = @SqlConfig(encoding = "utf-8", separator = ";", commentPrefix = "--", dataSource = "dataSource1", transactionManager = "txManager1")) public void test01_simple() { //判断是在事务中执行 Assert.assertTrue(TransactionSynchronizationManager.isActualTransactionActive()); Assert.assertTrue(TestTransaction.isActive()); Assert.assertEquals( Integer.valueOf(3), jdbcTemplate1.queryForObject("select count(1) from users", Integer.class)); } @Test @Transactional("txManager2") @Sql(value = {"classpath:schema.sql", "classpath:init-data.sql"}, config = @SqlConfig(encoding = "utf-8", separator = ";", commentPrefix = "--", dataSource = "dataSource2", transactionManager = "txManager2")) public void test02_simple() { Assert.assertEquals( Integer.valueOf(2), jdbcTemplate2.queryForObject("select count(1) from users", Integer.class)); } @Test @Transactional("txManager2") @Sql(value = {"classpath:schema.sql", "classpath:init-data.sql"}, config = @SqlConfig(encoding = "utf-8", separator = ";", commentPrefix = "--", dataSource = "dataSource2", transactionManager = "txManager2")) public void test03_simple() { Assert.assertEquals( Integer.valueOf(2), jdbcTemplate2.queryForObject("select count(1) from users", Integer.class)); TestTransaction.flagForRollback(); } @Rule public TestName testName = new TestName(); @AfterTransaction public void afterTransaction() { System.out.println(testName.getMethodName()); if("test03_simple".equals(testName.getMethodName())) { Assert.assertEquals( Integer.valueOf(0), jdbcTemplate2.queryForObject("select count(1) from users", Integer.class)); } } }
可以使用//判断是在事务中执行TransactionSynchronizationManager.isActualTransactionActive()或TestTransaction.isActive()来判断是否是在事务中执行;通过TestTransaction.flagForRollback();来回滚事务;在测试用例中@AfterTransaction来断言回滚后数据没有插入。
