前后端分离状态下，出现跨域问题
1：全局结局
在启动类上加上
private CorsConfiguration buildConfig() {
CorsConfiguration corsConfiguration = new CorsConfiguration();
corsConfiguration.setAllowCredentials(true);
corsConfiguration.addAllowedOrigin("");
corsConfiguration.addAllowedHeader("");
corsConfiguration.addAllowedMethod("*");
corsConfiguration.addExposedHeader(HttpHeaders.ACCEPT);
return corsConfiguration;
}
/**
* 跨域过滤器
*
* @return
/
@Bean
public CorsFilter corsFilter() {
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", buildConfig()); // 4
return new CorsFilter(source);
}
2：单个controller解决办法
加上注解
//@CrossOrigin(origins = "",maxAge = 3600)
