英文:
NoSuchBeanDefinitionException for NamedParameterJdbcTemplate in test class
问题
在我的 Spring Boot 应用程序中，我在使用 JdbcTemplate 运行单元测试时遇到了问题。我有以下用于配置的代码：
@Configuration
@ComponentScan("com.idoc.recon.persistence")
public class SpringJDBCConfig {
@Value("${spring.datasource.url}")
private String url;
@Value("${spring.datasource.username}")
private String username;
@Value("${spring.datasource.password}")
private String password;
@Value("${spring.datasource.driver-class-name:oracle.jdbc.pool.OracleDataSource}")
private String driverClassName;
@Bean(name = "OracleUniversalConnectionPool")
@Primary
public DataSource getDataSource() {
PoolDataSource dataSource = null;
try {
dataSource = PoolDataSourceFactory.getPoolDataSource();
dataSource.setConnectionFactoryClassName(driverClassName);
dataSource.setURL(url);
dataSource.setUser(username);
dataSource.setPassword(password);
dataSource.setFastConnectionFailoverEnabled(true);
dataSource.setInitialPoolSize(5);
dataSource.setMinPoolSize(5);
dataSource.setMaxPoolSize(10);
} catch (SQLException ea) {
System.err.println("Error connecting to the database: " + ea.getMessage());
}
return dataSource;
}
}
还有用于存储库类的代码：
@Repository
public class CompanyRepositoryImplementation implements CompanyRepository {
protected final Log logger = LogFactory.getLog(CompanyRepositoryImplementation.class);
@Autowired
private NamedParameterJdbcTemplate jdbcTemplate;
@Override
public long createMdCompany(CreateCompanyRequest company) throws DaoException { /* 一些代码 */ }
}
这段代码通过调用例如 Postman 中的 REST 服务来运行。我编写了以下单元测试来仅测试存储库部分：
@ExtendWith(SpringExtension.class)
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@ContextConfiguration(classes = {
com.idoc.recon.persistence.dao.interfaces.implementations.CompanyRepositoryImplementation.class,
com.idoc.recon.persistence.dao.configuration.SpringJDBCConfig.class })
public class CompanyRepositoryTest {
@Autowired
CompanyRepository companyRepository;
@Test
public void createMdCompanyTest() { /* 一些代码 */ }
}
但是当我运行 JUnit 测试时，我收到以下错误消息：
... （错误消息的详细内容）
有人能帮助我找出缺少了什么吗？
英文:
I have a problem with running unit tests with JDBCTemplate in my spring boot application. I have the following code for configuration:
@Configuration
@ComponentScan("com.idoc.recon.persistence")
public class SpringJDBCConfig {
@Value("${spring.datasource.url}")
private String url;
@Value("${spring.datasource.username}")
private String username;
@Value("${spring.datasource.password}")
private String password;
@Value("${spring.datasource.driver-class-name:oracle.jdbc.pool.OracleDataSource}")
private String driverClassName;
@Bean(name = "OracleUniversalConnectionPool")
@Primary
public DataSource getDataSource() {
PoolDataSource dataSource = null;
try {
dataSource = PoolDataSourceFactory.getPoolDataSource();
dataSource.setConnectionFactoryClassName(driverClassName);
dataSource.setURL(url);
dataSource.setUser(username);
dataSource.setPassword(password);
dataSource.setFastConnectionFailoverEnabled(true);
dataSource.setInitialPoolSize(5);
dataSource.setMinPoolSize(5);
dataSource.setMaxPoolSize(10);
} catch (SQLException ea) {
System.err.println("Error connecting to the database: " + ea.getMessage());
}
return dataSource;
}
and this is for repository class:
@Repository
public class CompanyRepositoryImplementation implements CompanyRepository {
protected final Log logger = LogFactory.getLog(CompanyRepositoryImplementation.class);
@Autowired
private NamedParameterJdbcTemplate jdbcTemplate;
@Override
public long createMdCompany(CreateCompanyRequest company) throws DaoException { stuff..}
}
that works by calling the Rest service from postman for example.
I wrote this unit test to test only the repository part:
@ExtendWith(SpringExtension.class)
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@ContextConfiguration(classes = {
com.idoc.recon.persistence.dao.interfaces.implementations.CompanyRepositoryImplementation.class,
com.idoc.recon.persistence.dao.configuration.SpringJDBCConfig.class })
public class CompanyRepositoryTest {
@Autowired
CompanyRepository companyRepository;
@Test
public void createMdCompanyTest() {stuff..}
}
but when i run the junit test i recive the following error:

could someone help me figure out what's missing?

使用带有DataSource参数的setter添加@Autowired：
private NamedParameterJdbcTemplate namedParameterJdbcTemplate;
@Autowired
public void setDataSource(DataSource dataSource) {
this.namedParameterJdbcTemplate = new NamedParameterJdbcTemplate(dataSource);
}
英文:
Add @Autowired using a setter with DataSource parameter:
private NamedParameterJdbcTemplate namedParameterJdbcTemplate;
@Autowired
public void setDataSource(DataSource dataSource) {
this.namedParameterJdbcTemplate = new NamedParameterJdbcTemplate(dataSource);
}
