4 springboot集成Cors,在appliction.java中添加这段

	@Bean
	public WebMvcConfigurer corsConfigurer() {
		return new WebMvcConfigurerAdapter() {
			@Override
			public void addCorsMappings(CorsRegistry registry) {
				registry.addMapping("/**")
						.allowedOrigins("*")
						.allowedMethods("PUT", "DELETE","GET","POST")
						.allowedHeaders("*")
						.exposedHeaders("access-control-allow-headers",
								"access-control-allow-methods",
								"access-control-allow-origin",
								"access-control-max-age",
								"X-Frame-Options")
						.allowCredentials(false).maxAge(3600);
			}
		};

	}
