方法一： 1.把你的headers改成params
方法二：2.配置文件上面加上SimpleCORSFilter跨域请求的过滤器
axios({
url:url5,
method:"post",
headers:{
token:token
},
data:cart
}).then( res=>{
console.log("------购物车信息-----");
console.log(res);
}
);
可以把你的headers换成params试试看：
axios({
url:url5,
method:"post",
params:{
token:token
},
data:cart
}).then( res=>{
console.log("------购物车信息-----");
console.log(res);
}
);
2.加上SimpleCrosFileter过滤器
response.addHeader("Access-Control-Allow-Headers"," Access-Control-Allow-Headers,
token,Origin,Accept, X-Requested-With, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers");
我的加入了token这个请求头，从前端获取的数据。

chain.doFilter(req, res);
