JAVA版本從1.8升級到1.9
有一些依賴庫河绽，從1.9中分離了，需要手動添加挪拟，不然會出現(xiàn)java.lang.NoClassDefFoundError錯誤
報錯如下
org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tomcatEmbeddedServletContainerFactory' defined in class path resource [org/springframework/boot/autoconfigure/web/EmbeddedServletContainerAutoConfiguration$EmbeddedTomcat.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.web.HttpEncodingAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'spring.http.encoding-org.springframework.boot.autoconfigure.web.HttpEncodingProperties': Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: javax/xml/bind/ValidationException
注意最后的
nested exception is java.lang.NoClassDefFoundError: javax/xml/bind/ValidationException
這是缺少依賴庫校坑，在pom.xml中加上依賴就搞定
