  • springboot的常见问题错误

    一:

    org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name

    2019-03-08 16:07:14.132 ERROR 9936 --- [ main] o.s.test.context.TestContextManager : Caught exception while allowing TestExecutionListener [org.springframework.boot.test.autoconfigure.SpringBootDependencyInjectionTestExecutionListener@2f7c2f4f] to prepare test instance [com.example.demo.DemoApplicationTests@5491f68b]

    org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.example.demo.DemoApplicationTests': Unsatisfied dependency expressed through field 'person'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.beans.Person' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
    at org.springframework.beans.factory.annotation

    是因为测试的application类访问不到autowired注解的属性的对象所在的包。

    application只能访问同一包下的文件,或者是同一包下的子文件

     二:

    java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test

    是因为application和junit所在的包名不一样导致

    三:是因为yml文件中存在tab键等yml文件有问题

    java.lang.IllegalStateException: Failed to load property source from location 'classpath:/application.yml'
