SpringBoot测试junit遇到的坑及解决

目录一、NullPointerException原因解决二、org.springframework.context.ApplicationContextException三、java.lang.NoClassDefFoundError原因四、Error:(9,45) java: 程序包org.springframework.boot.test.context不存在解决方法五、java.lang.IllegalStateException: Failed to load ApplicationContext原因解决方法六、java.lang.Exception: No runnable methods原因解决办法

一、NullPointerException

@SpringBootTest

public class TestDemo {

@Autowired

private ITCompanyService companyService;

@Test

public void getCom(){

try {

CompanyPkSearchRespVo vo = companyService.getCompanyPkSearchByCompanyId("257949626441666560");

System.out.println("这是一个测试类");

} catch (Exception e) {

e.printStackTrace();

}

出错：NullPointerException

原因

service层依赖注入不进来

解决

@SpringBootTest，加入启动类Application后就可以了

二、org.springframework.context.ApplicationContextException

出错：org.springframework.context.ApplicationContextException

三、java.lang.NoClassDefFoundError

错误：java.lang.NoClassDefFoundError: org/springframework/core/annotation/MergedAnnotations$SearchStrategy

原因

spring的版本导致的问题，引入了spring的其他包包含了spring-core，且版本为4.0.3.RELEASE，而我自己引入的spring-test版本为4.0.0.RELESASE，这个包里也包含了spring-core，从而导致spring-core包版本不一致产生了冲突，最后运行报错。

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

明明自己仓库有这个jar报，但就是install项目的时候报Error:(9,45) java: 程序包org.springframework.boot.test.context不存在，

解决方法

将本地仓库spring-boot-test文件夹删除，重新下载install

六、java.lang.Exception: No runnable methods

五月 12, 2020 11:37:07 上午 org.junit.vintage.engine.descriptor.RunnerTestDescriptor warnAboutUnfilterableRunner警告: Runner org.junit.internal.runners.ErrorReportingRunner (used on class wwfww.warehouse.TestDemo) does not support filtering and will therefore be run completely.

原因

@Test导入的包错了，spring-test需要的Junit是org.junit.Test，但是在@Test有两个包，另一个是org.junit.jupiter.api.Test，如果将org.junit.Test导错成了org.junit.jupiter.api.Test就会报这个错误，改正包之后问题解决

解决办法

包改成org.junit.Test
