springboot备忘

1.springboot中有ApplicationRunner类，如果项目中的启动类名称也是ApplicationRunner，单元测试时需要注意：import不要import到springboot的类了

@RunWith(SpringJUnit4ClassRunner.class)

@SpringBootTest(classes = ApplicationRunner.class)

import org.springframework.boot.ApplicationRunner;

2.Could not open windows registry node SoftwareJavaSoftPrefs at root 0x80000002 

=>regedit:HKEY_LOCAL_MACHINE->SOFTWARE->JavaSoft->Prefs

Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private java.lang.String org.springframework.boot.autoconfigure.web.ErrorMvcAutoConfiguration.errorPath;
