ApplicationContext 加载失败,完全错误-

Description:

Parameter 0 of method createDatasourceBean in com.siemens.plm.it.configurator.DatasourceConfigurator required a bean of type 'java.lang.String' that could not be found.


Action:

Consider defining a bean of type 'java.lang.String' in your configuration.

-com.someproject //SpringApplication.run
--com.someproject.test

并且包含了一些基本的MVC测试,但是在我的测试中,这个应用程序失败了 contextLoad() -

@RunWith(SpringRunner.class)
@SpringBootTest
public class SapConnectionApplicationTests {

    @Test
    public void contextLoads() {
    }

}

运行没有测试的构建(-dSkipTest)可以工作,而运行项目可以工作,只有测试类失败。

public abstract class DatasourceConfigurator {
    @Bean
   public TomcatEmbeddedServletContainerFactory embeddedServletContainerFactory() {
      return new 1(this);
   }

    protected ContextResource createContextResource(DatasourceProperties dbp) {
        ContextResource resource = new ContextResource();
        resource.setName(dbp.getJndiname());
        resource.setType(DataSource.class.getName());
        resource.setProperty("driverClassName", dbp.getDriverClassName());
        resource.setProperty("factory", dbp.getFactory());
        resource.setProperty("url", dbp.getUrl());
        resource.setProperty("username", dbp.getUsername());
        resource.setProperty("password", dbp.getPassword());
        resource.setProperty("initialSize", dbp.getInitialSize());
        resource.setProperty("maxActive", dbp.getMaxActive());
        resource.setProperty("minIdle", dbp.getMinIdle());
        resource.setProperty("maxIdle", dbp.getMaxIdle());
        return resource;
    }

    @Bean(destroyMethod = "")
    protected DataSource createDatasourceBean(String jndiName) throws IllegalArgumentException, NamingException {
        JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
        bean.setJndiName(jndiName);
        bean.setProxyInterface(DataSource.class);
        bean.setLookupOnStartup(false);
        bean.setResourceRef(true);
        bean.afterPropertiesSet();
        return (DataSource) bean.getObject();
    }

    @Bean
    public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
        return new PersistenceExceptionTranslationPostProcessor();
    }

    protected abstract List<DatasourceProperties> getDatasourceProperties();
}

试着宣布一个被嘲笑的 DataSource 测试类中的bean:

@MockBean
DataSource dataSource;

然后用 Mockito.when .

Spring告诉您它正在尝试使用 com.siemens.plm.it.configurator.DatasourceConfigurator.createDatasourceBean

您说这只是在测试运行期间失败,而不是在加载应用程序时失败,这。。。表明jndi名称在应用程序启动期间可用于应用程序上下文自动连接,但在测试运行时不可用。我没有什么好的建议来解释为什么会这样。如果我在此时尝试调试,我可能会在 createDatasourceBean 并在调试器中启动应用程序,找出Spring从何处获取 jndiName
