1、如果只是一个简单的springboot demo,用以下配置就行
新建config类

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
/**
* @author yk
* @date 2021/7/19 14:36
*/
@Configuration
public class WebConfig implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping( "/**" )
.allowedOriginPatterns( "*" )
.allowedMethods( "*" )
.maxAge( 3600 )
.allowCredentials( true );
}
}
```

2、但是实际开发中我们需要结合,spring-security、oauth2等等,就会发现上面的配置失效了,那是因为前面的Filter优先级太高了,那我们可以采取如下配置

11

import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.Ordered;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;
/**
* @author yk
* @date 2021/7/19 16:21
*/
@Configuration
public class CrosConfig {
@Bean
public FilterRegistrationBean corsFilter() {
CorsConfiguration config = new CorsConfiguration();
config.setAllowCredentials( true );
config.addAllowedOriginPattern( "*" );
config.addAllowedHeader( "*" );
config.addAllowedMethod( "*" );
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration( "/**" , config);
FilterRegistrationBean bean = new FilterRegistrationBean( new CorsFilter(source));
//这里设置优先级最高
bean.setOrder(Ordered.HIGHEST_PRECEDENCE);
return bean;
}
}
