Springboot跨域问题三种解决方案

使用vue+axios+spring boot前后端分离项目时会出现跨域问题

解决方式:

一: 全局配置

  @Override
  public void addCorsMappings(CorsRegistry registry) {
    registry
 .addMapping("
 @RestController
 @RequestMapping("/user")
 @RequiredArgsConstructor
 @CrossOrigin(origins = "*",maxAge = 3600)
 public class UserController {
   final UserMapper userMapper;
   @GetMapping("/getOne/{id}")
   public User getOne(@PathVariable("id") Integer id) {
     return userMapper.getById(id);
   }
 }

三: 自定义跨域过滤器

1,编写过滤器

class CrosFilter implements Filter {

  @Override
  public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
    HttpServletResponse res = (HttpServletResponse) response;
    /
  @Bean
  public FilterRegistrationBean registerFilter(){
    FilterRegistrationBean bean = new FilterRegistrationBean();
    bean.addUrlPatterns("/*");
    bean.setFilter(new CrosFilter());
    return bean;
  }
