spring mvc 支持options方法

在web.xml中，添加

<init-param><param-name>dispatchOptionsRequest</param-name><param-value>true</param-value></init-param>

添加后

<servlet><servlet-name>springdispatcher</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springMvc-viewresolver.xml</param-value></init-param><init-param><param-name>dispatchOptionsRequest</param-name><param-value>true</param-value></init-param><load-on-startup>1</load-on-startup></servlet>
