SpringBoot配置Access-Control-Allow-Origin

1. 配置过滤器

@Component
@WebFilter(urlPatterns = "/*", filterName = "CorsFilter")
public class CorsFilter implements Filter {@Overridepublic void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {HttpServletResponse response = (HttpServletResponse) res;HttpServletRequest reqs = (HttpServletRequest) req;String curOrigin = reqs.getHeader("Origin");response.setHeader("Access-Control-Allow-Origin", curOrigin == null ? "true" : curOrigin);response.setHeader("Access-Control-Allow-Credentials", "true");response.setHeader("Access-Control-Allow-Methods", "POST, GET, PATCH, DELETE, PUT");response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");chain.doFilter(req, res);}@Overridepublic void init(FilterConfig filterConfig) {}@Overridepublic void destroy() {}}

2. webconfig 配置文件

@Configuration
public class CorsConfig  extends WebMvcConfigurerAdapter {@Overridepublic void addCorsMappings(CorsRegistry registry) {registry.addMapping("/**").allowedOrigins("*").allowedMethods("GET", "HEAD", "POST","PUT", "DELETE", "OPTIONS").allowCredentials(true).maxAge(3600);}}

@Configuration
public class XXXXMvcConfigurer implements WebMvcConfigurer {@Overridepublic void addCorsMappings(CorsRegistry registry) {registry.addMapping("/**").allowedOrigins("*").allowCredentials(true).allowedMethods("GET", "POST", "DELETE", "PUT","PATCH").maxAge(3600);}
}
