跨域访问（cors） access-control-allow-origin 多个域名

1.首先要了解问什么访问要跨域

2.配置多个作用访问

资源文件中修改app.allowOrigin = http:XXX,HTTP:kkk,..

或者app.allowOrigin = * 这种相对来说风险极大

public void doFilter(ServletRequest servletRequest,
ServletResponse servletResponse, FilterChain filterChain)
throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) servletRequest;
HttpServletResponse response = (HttpServletResponse) servletResponse;
HttpSession session = request.getSession();

if ("true".equals(PropertiesUtils.getProperty("app.debug"))) {
// 允许跨域访问
response.setHeader("Access-Control-Allow-Origin",
PropertiesUtils.getProperty("app.allowOrigin"));
response.setHeader("Access-Control-Allow-Headers",
"Origin, X-Requested-With, Content-Type, Accept, Cookie");
response.setHeader("Access-Control-Allow-Methods",
"GET, POST, PUT, DELETE, OPTIONS");
response.setHeader("Access-Control-Allow-Credentials", "true");
}
}
