首先交代一下,我的jdk是1.8tomcat是8.0,我的项目是ssm+maven。
spring的框架是4.3.在使用的时候,只需要在controller的@controller注解之前注解@CrossOrigin,然后在springmvc.xml的配置文件添加
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
//与此次操作无关的配置都省略了
<mvc:cors>
<mvc:mapping path="/**"
allowed-origins=""
allowed-methods="POST,GET,OPTIONS,DELETE,PUT"
//header里面userName与passWord是由于项目的需要我自定义的请求头的内容。
allowed-headers="Origin,X-Mx-ReqToken,x-requested-with,userName,passWord,Authorization,Accept,content-type"
allow-credentials="true"/>
</mvc:cors>
</beans>
这里是controller层添加注解的截图
