Spring 告诉您它正在尝试使用 com.siemens.plm.it.configurator.DatasourceConfigurator.createDatasourceBean 创建一个 bean，并且该方法需要一个字符串，并且不确定从哪里获取该字符串。因此，要么您需要提供一个可以自动装配的字符串，要么您必须弄清楚为什么 Spring 试图在上下文加载期间调用该方法。
你说这只是在测试期间失败 运行 而不是在加载应用程序时，这...表明 jndi 名称以某种方式可用于应用程序启动期间的应用程序上下文自动连接但不是当测试是 运行ning 时。关于为什么会这样，我没有很好的建议。如果我此时尝试调试，我可能会在 createDatasourceBean 上放置一个断点并在调试器中启动应用程序并找出 Spring 从哪里获取 jndiName ，也许那会告诉我为什么它在 运行测试时不能做同样的事情。
Spring 有很多方法可以解析属性和组件，这是超级灵活的，但这种灵活性是有代价的。如果您对应用程序不太熟悉，可能很难猜出某些内容的来源。
尝试在测试中声明一个模拟的 DataSource bean class:
@MockBean
DataSource dataSource;
然后使用 Mockito.when 模拟它的方法。
我遇到问题 运行 我的 Spring 启动测试， ApplicationContext 加载失败，完全错误 -

测试class在我的src/test/java根项目包下-
-com.someproject //SpringApplication.run
--com.someproject.test
并包含一些基本的 MVC 测试，但在我的 contextLoad() -
@RunWith(SpringRunner.class)
@SpringBootTest
public class SapConnectionApplicationTests {
@Test
public void contextLoads() {
}
}
///编辑
运行 没有测试的构建（-dSkipTest）有效，并且 运行 项目有效，它只是测试 classes 失败。

Spring 告诉您它正在尝试使用 com.siemens.plm.it.configurator.DatasourceConfigurator.createDatasourceBean 创建一个 bean，并且该方法需要一个字符串，并且不确定从哪里获取该字符串。因此，要么您需要提供一个可以自动装配的字符串，要么您必须弄清楚为什么 Spring 试图在上下文加载期间调用该方法。
你说这只是在测试期间失败 运行 而不是在加载应用程序时，这...表明 jndi 名称以某种方式可用于应用程序启动期间的应用程序上下文自动连接但不是当测试是 运行ning 时。关于为什么会这样，我没有很好的建议。如果我此时尝试调试，我可能会在 createDatasourceBean 上放置一个断点并在调试器中启动应用程序并找出 Spring 从哪里获取 jndiName ，也许那会告诉我为什么它在 运行测试时不能做同样的事情。
Spring 有很多方法可以解析属性和组件，这是超级灵活的，但这种灵活性是有代价的。如果您对应用程序不太熟悉，可能很难猜出某些内容的来源。
尝试在测试中声明一个模拟的 DataSource bean class:
@MockBean
DataSource dataSource;
然后使用 Mockito.when 模拟它的方法。
