Spring Boot前后端分離跨域問題

在SpringBoot+Spring Security的服務器端加入如下代碼，已解決跨域帶來的問題

import java.io.IOException;

import javax.servlet.Filter;

import javax.servlet.FilterChain;

import javax.servlet.FilterConfig;

import javax.servlet.ServletException;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.springframework.context.annotation.Configuration;

import org.springframework.core.Ordered;

import org.springframework.core.annotation.Order;

@Order(Ordered.HIGHEST_PRECEDENCE)

@Configuration

public class CorsFilter implements Filter {

    @Override

    public void init(FilterConfig filterConfig) throws ServletException {

    }

    @Override

    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {

        HttpServletRequest request = (HttpServletRequest) servletRequest;

        HttpServletResponse response = (HttpServletResponse) servletResponse;

        response.setHeader("Access-Control-Allow-Origin","*");

        response.setHeader("Access-Control-Allow-Credentials","true");

        response.setHeader("Access-Control-Allow-Methods","POST,GET,OPTIONS,PUT,DELETE,PATCH,HEAD");

        response.setHeader("Access-Control-Allow-Max-Age","3600");

        response.setHeader("Access-Control-Allow-Headers","*");

        if("OPTIONS".equalsIgnoreCase(request.getMethod())){

            response.setStatus(HttpServletResponse.SC_OK);

        }else{

            filterChain.doFilter(servletRequest,servletResponse);

        }

    }

    @Override

    public void destroy() {

    }

}
