spring boot 跨域问题

这里采用编写Filter过滤器解决。

@Component
public class CorsFilter implements Filter {

    @Value("${spring.profiles.active}")
    private String active;

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {

    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse httpServletResponse = (HttpServletResponse) response;
        Set allowedOrigins= new HashSet();
        if (Constants.PROD.equals(active)){
            //生产环境
            allowedOrigins.add("http://xzh.xzh.com");
            allowedOrigins.add("http://47.98.86.111");
        }else{
            //其他环境
            allowedOrigins.add("http://test.xzh.com");
            allowedOrigins.add("http://localhost:4865");
        }
        String originHeader = ((HttpServletRequest) request).getHeader("Origin");
        if (allowedOrigins.contains(originHeader)){
            httpServletResponse.setHeader("Access-Control-Allow-Origin", originHeader);
            httpServletResponse.setHeader("Access-Control-Allow-Headers", "User-Agent,Origin,Cache-Control,Content-type,Date,Server,withCredentials,AccessToken");
            httpServletResponse.setHeader("Access-Control-Allow-Credentials", "true");
            httpServletResponse.setHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS, HEAD");
            httpServletResponse.setHeader("Access-Control-Max-Age", "1209600");
            httpServletResponse.setHeader("Access-Control-Expose-Headers", "accesstoken");
            httpServletResponse.setHeader("Access-Control-Request-Headers", "accesstoken");
        }
        chain.doFilter(request, response);
    }

    @Override
    public void destroy() {

    }

}
