Java中SSM框架解决跨域请求问题

@CrossOrigin // 允许所有ip跨域
@CrossOrigin(origins = "192.168.0.1") //只允许指定ip跨域

<!-- 接口跨域配置 -->
<mvc:cors>
	<!-- allowed-methods="*" --> <!-- 表示所有请求都有效 -->
	<mvc:mapping path="/**" allowed-origins="*"
		allowed-methods="POST, GET, OPTIONS, DELETE, PUT"
		allowed-headers="Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With"
		allow-credentials="true" />
</mvc:cors>
