一、NullPointerException

@SpringBootTest public class TestDemo {@Autowiredprivate ITCompanyService companyService;@Testpublic void getCom(){try {CompanyPkSearchRespVo vo = companyService.getCompanyPkSearchByCompanyId("257949626441666560");System.out.println("這是一個測試類");} catch (Exception e) {e.printStackTrace();}} }

出錯：NullPointerException
原因：service層依賴注入不進來
解決：@SpringBootTest，加入啟動類Application后就可以了
參考鏈接

二、org.springframework.context.ApplicationContextException

出錯：org.springframework.context.ApplicationContextException

三、java.lang.NoClassDefFoundError

錯誤：java.lang.NoClassDefFoundError: org/springframework/core/annotation/MergedAnnotations$SearchStrategy
原因：spring的版本導致的問題，引入了spring的其他包包含了spring-core，且版本為4.0.3.RELEASE，而我自己引入的spring-test版本為4.0.0.RELESASE，這個包里也包含了spring-core，從而導致spring-core包版本不一致產生了沖突，最后運行報錯。

四、Error:(9,45) java: 程序包org.springframework.boot.test.context不存在

明明自己倉庫有這個jar報，但就是install項目的時候報Error:(9,45) java: 程序包org.springframework.boot.test.context不存在，
解決方法：將本地倉庫spring-boot-test文件夾刪除，重新下載install

六、java.lang.Exception: No runnable methods

com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70)

原因：@Test導入的包錯了，spring-test需要的Junit是org.junit.Test，但是在@Test有兩個包，另一個是org.junit.jupiter.api.Test，如果將org.junit.Test導錯成了org.junit.jupiter.api.Test就會報這個錯誤，改正包之后問題解決

解決辦法：包改成org.junit.Test
