您可以通过实现Filter来允许所有标头。
试试这个：
@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class CORSFilter implements Filter {
@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
HttpServletResponse response = (HttpServletResponse) res;
HttpServletRequest request = (HttpServletRequest) req;
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods", "*");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "*");
//response.setHeader("Access-Control-Expose-Headers","yourCustomHeaderIfExist");
if ("OPTIONS".equalsIgnoreCase(request.getmethod())) {
response.setStatus(HttpServletResponse.SC_OK);
} else {
chain.doFilter(req, res);
}
}
@Override
public void init(FilterConfig filterConfig) {
}
@Override
public void destroy() {
}
}
并@CrossOrigin在控制器之前添加注释。
您也可以尝试添加以下bean：
@Bean
public WebMvcConfigurer corsConfigurer() {
return new WebMvcConfigurerAdapter() {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**").allowedOrigins("*").allowedMethods("GET", "POST","PUT", "DELETE");
}
};
}
