Question

我有测试代码，我想在其中读取consul的配置。application.properties（src / main / resources）启用consul配置。我有一个POJO类名DBConfig（在src / main / java中），它从领事那里获取配置。我已经在测试类中自动连接了DBConfig，并且当我运行单元测试时，它给了我nullpointerexception，因为它没有从领事那里获取值。如何处理情况。请帮忙。

@Configuration
@ConfigurationProperties(prefix="db")
@RefreshScope

public class DBConfig {

    private String jdbcURL;
    private String username;
    private String password;
    private String driverClass;

...getter setters.

}

测试类---

@RunWith(MockitoJUnitRunner.class)
@Transactional(propagation=Propagation.REQUIRED,readOnly=false,rollbackFor=Exception.class)
@SpringBootTest(classes={DBConfig.class})
public class TestUserDao extends DBTestCase {

    @Autowired
    private DBConfig dbConfig;

    protected final Resource res = new ClassPathResource("actualDataSet.xml");

    @Bean
    @Profile("test")
    @RefreshScope
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(dbConfig.getDriverClass());
        dataSource.setUrl(dbConfig.getJdbcURL());
        dataSource.setUsername(dbConfig.getUsername());
        dataSource.setPassword(dbConfig.getPassword());

        return dataSource;
    }

    @Bean
    @Autowired
    public NamedParameterJdbcTemplate jdbcTemplate(DataSource dataSource) {
        return new NamedParameterJdbcTemplate(dataSource);
    }

    @Bean
    @Autowired
    public UserDAO userDAO(NamedParameterJdbcTemplate jdbcTemplate) {
        return new UserDAO(jdbcTemplate);
    }

    @Override
    protected IDataSet getDataSet() throws Exception {
        ClassLoader classLoader = getClass().getClassLoader();
        String file = classLoader.getResource("actualDataSet.xml").getFile();
        return new FlatXmlDataSetBuilder().build(new FileInputStream(file));
    }

    protected DatabaseOperation getSetUpOperation() throws Exception {
        return DatabaseOperation.REFRESH;
    }

    @Test
    public void insertTodo() throws Exception {

    }

    protected DatabaseOperation getTearDownOperation() throws Exception {
        return DatabaseOperation.DELETE;
    }

这可能是由于使用MockitoJUnitRunner类引起的，该类在启动时不会加载ApplicationContext，这意味着将无法访问您的bean。

一旦您将在SpringRunner批注中使用@RunWith()类，Spring应该能够注入DBConfig bean。

测试类无法读取领事配置
