Spring Boot Main 类 Junit 测试抛出错误
Posted
技术标签:
【中文标题】Spring Boot Main 类 Junit 测试抛出错误【英文标题】：Spring Boot Main class Junit test throwing error 【发布时间】：2018-06-27 01:35:34 【问题描述】：这是 Spring boot 主类
@SpringBootApplication
@EnableDiscoveryClient
public class Application
private static final Logger LOGGER = LoggerFactory.getLogger(Application.class);
public static void main(String[] args)
LOGGER.info("Starting Application");
ConfigurableApplicationContext context = new SpringApplicationBuilder(Application.class)
.properties("spring.config.name:application,db-config")
.build().run(args);
ConfigurableEnvironment environment = context.getEnvironment();
LOGGER.info("OpendoorServiceApplication config file loaded successfully: ", environment.getProperty("spring.application.name"));
LOGGER.info("Database config file loaded successfully: ", environment.getProperty("mes.db.environment"));
这是这个类的junit类
@RunWith(SpringRunner.class)
@SpringBootTest(classes=Application.class)
public class ApplicationTests
@Test
public void applicationContextLoaded()
得到这个异常
更新应用程序的配置

有人可以帮我解决这个问题吗？
【问题讨论】：
发布完整的堆栈跟踪.. @M.Deinum 更新了完整的堆栈跟踪 【参考方案1】：这是您的堆栈跟踪的摘录：
3 errors
Field error in object 'mes.db' on field 'password': rejected value [null]; codes [NotNull.mes.db.password,NotNull.password,NotNull.java.lang.String,NotNull]; arguments
[org.springframework.context.support.DefaultMessageSourceResolvable: codes [mes.db.password,password]; arguments []; default message [password]]; default message [may not be null]
Field error in object 'mes.db' on field 'url': rejected value [null]; codes [NotNull.mes.db.url,NotNull.url,NotNull.java.lang.String,NotNull]; arguments
[org.springframework.context.support.DefaultMessageSourceResolvable: codes [mes.db.url,url]; arguments []; default message [url]]; default message [may not be null]
Field error in object 'mes.db' on field 'username': rejected value [null]; codes [NotNull.mes.db.username,NotNull.username,NotNull.java.lang.String,NotNull]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [mes.db.username,username]; arguments []; default message [username]]; default message [may not be null]
基本上这意味着您必须为以下各项指定值：
密码 网址 用户名在您的数据库配置中
【讨论】：
它们已被指定。在运行应用程序时它工作正常。但是在junit测试期间它不起作用 你可以尝试在 src/test/resources 文件夹中复制粘贴相同的配置吗？ 我也试过了。还有什么我需要添加到junit测试类 您使用的是哪个 JUnit 跑步者？你试过使用@SpringBootTest 吗？ 请看我上面的junit类。我正在使用@SpringBootTest以上是关于Spring Boot Main 类 Junit 测试抛出错误的主要内容，如果未能解决你的问题，请参考以下文章
我是不是需要使用 Kotlin Junit5 和 Spring Boot 将 Spring 注释复制到内部类？
