Spring Boot 中实现跨域的多种方式小结

@RestController
@CrossOrigin(origins = "http://localhost:3000")
public class MyController {
    // Controller methods
}

@Configuration
public class WebConfig implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/api/**")
                .allowedOrigins("http://localhost:3000")
                .allowedMethods("GET", "POST", "PUT", "DELETE")
                .allowCredentials(true);
    }
}

@Component
public class CorsFilter implements Filter {
    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        HttpServletResponse httpResponse = (HttpServletResponse) response;
        httpResponse.setHeader("Access-Control-Allow-Origin", "http://localhost:3000");
        httpResponse.setHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE");
        httpResponse.setHeader("Access-Control-Allow-Credentials", "true");
        chain.doFilter(request, response);
    }
}

spring.mvc.cors.allowed-origins=http://localhost:3000
spring.mvc.cors.allowed-methods=GET,POST,PUT,DELETE
spring.mvc.cors.allow-credentials=true
