Spring Framework RESTful services

Question

Я создаю свой первый API RESTful Spring на Eclipse. Я не могу назвать API. Я получаю: «Запрошенный ресурс недоступен». ошибка когда я использую http://localhost:8080/InterVUEService/api/Clinic/7.

Не могли бы вы рассказать мне, почему я не могу позвонить http://localhost:8080/api/Clinic/id? Почему этот Uri не работает на моем сервере Tomcat? Пожалуйста помоги. Я полный новичок и учился писать Restful services для моего следующего проекта на работе для размещения на AWS.

Благодаря Nalini

Answer 1

<context:component-scan base-package="com.abaxis.interVUEservice.*dao"/> 

может попытаться изменить к

<context:component-scan base-package="com.abaxis.interVUEservice" /> 

и использовать http://localhost:8080/InterVUEService/api/Clinic/7

Answer 2

Спасибо Murali помог мне решить эту проблему. Я изменил url-шаблон в web.xml на <url-pattern>/</url-pattern> с <url-pattern>/InterVUEService/*</url-pattern>, и мне удалось вызвать API и получить ответ json. Проблема была в том, что когда шаблон url был /InterVUEService/*, uri должен был быть http://localhost:8080/InterVUEService/InterVUEService/api/Clinic/7, и я пытался с http://localhost:8080/InterVUEService/api/Clinic/7.

Надеюсь, это поможет кому-то еще с той же проблемой.
