spring boot跨域设置

Posted 2023-05-06

参考技术A

方式一

在需要跨域的整个Controller或者单个方法上添加@CrossOrigin注解

方式二(全局配置)

方式三(通过filter)

@Component

@WebFilter(urlPatterns = "/*", filterName = "authFilter") //这里的“/*” 表示的是需要拦截的请求路径

public class PassHttpFilter implements Filter

    @Override

    public void init(FilterConfig filterConfig) throws ServletException

    @Override

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

        HttpServletResponse httpResponse = (HttpServletResponse)servletResponse;

        httpResponse.setHeader("Access-Control-Allow-Headers","Origin, X-Requested-With, Content-Type, Accept");

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

        httpResponse.addHeader("Access-Control-Allow-Origin", "http://127.0.0.1:8080");

        filterChain.doFilter(servletRequest, httpResponse);

   

    @Override

    public void destroy()
