使用springboot 2 構(gòu)建項(xiàng)目，調(diào)試代碼的時(shí)候出現(xiàn)了如下的報(bào)錯(cuò)信息

第一眼看到這個(gè)問(wèn)題的時(shí)候感覺(jué)頭都比較大，那只能調(diào)試斷定，新建一個(gè)斷點(diǎn)，類(lèi)型是Java Exception Breakpoint，異常類(lèi)是上面拋出來(lái)的java.lang.ArrayStoreException，

通過(guò)調(diào)試查看是找不到org.springframework.boot.actuate.autoconfigure.EndpointAutoConfiguration這個(gè)類(lèi)，而AnnotationParser.parseClassValue把異常包裝成為Object，然后在sun.reflect.annotation.AnnotationParser.parseClassArray(int, ByteBuffer, ConstantPool, Class

result[i] = parseClassValue(buf, constPool, container);

而這里數(shù)組越界了，ArrayStoreException只有越界的Object的類(lèi)型信息，也就是上面的

java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy

發(fā)現(xiàn)是java.lang.ClassNotFoundException: org.springframework.boot.actuate.autoconfigure.EndpointAutoConfiguration，則加上@ConditionalOnClass的檢查就可以了.
