在测试中,我只需要测试方法insertData
:
@Component
public class DatabaseServiceImpl implements DatabaseService {
@Autowired
DataSource dataSource;
@Override
public int insertData(String var1, int var2, String var3, String var4, int var5, int var6) {
JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
return jdbcTemplate.update("INSERT INTO table_name_here VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)",
var1, var2, var3, var4, var5, var6,
null, null, null);
}
}
它使用dataSource,它是在java src的config类中的Bean中定义的,因此对于我的测试,我需要使用EmbeddedDataSource
,所以我这样编写测试:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = DatabaseServiceImplTestConfig.class, loader=AnnotationConfigContextLoader.class)
public class DatabaseServiceImplTest {
@Autowired
@Qualifier("embedded")
DataSource dataSource;
@Test
public void testInsertData() {
...........
DatabaseServiceImpl dsi = new DatabaseServiceImpl();
JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
assertEquals(1, dsi.insertData(var1, var2, var3, var4, var5, var6));
...........
}
当我调试它时,它说我正在使用EmbeddedDataSource
,但是JUint会抛出此异常:
java.lang.IllegalArgumentException: Property 'dataSource' is required
并指向此assertEquals
行。如何防止它从src包中要求DataSource
,以便可以使用此嵌入式代码完成测试?暂停
编辑
这是测试配置,我在其中指定需要使用的数据源(甚至设置名称):
@Bean(name="embedded")
public DataSource embeddedDataSource(DataSourceFactory embeddedDataSourceFactory) {
与src config类相同:
@Bean
public Datasource dataSource()
stackTrace是:
java.lang.IllegalArgumentException: Property 'dataSource' is required

但是我知道它指出了insertData方法内部的dataSource
答案 0 :(得分:2)
因为您在测试中正在执行new
,所以您失去了其他依赖项。对您的测试进行一些如下所示的重构将有助于修复。
@Autowired
private DatabaseService databaseService;
@Test
public void testInsertData() {
...........
JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
assertEquals(1, databaseService.insertData(datetime, days_rolling, host, start_or_stop, scenario_threadpool_size, days_rolling_weighted));
...........
}
,然后在测试配置中添加为databaseService创建的实例。
public class DatabaseServiceImplTestConfig {
@Bean
public DatabaseService databaseService() {
return new DatabaseServiceImpl();
}
}
