方式一:
package com.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;
/**
* 跨域配置
* @author
*/
@Configuration
public class CorsConfig {
private CorsConfiguration buildConfig() {
CorsConfiguration corsConfiguration = new CorsConfiguration();
// 1允许任何域名使用
corsConfiguration.addAllowedOrigin("*");
// 2允许任何头
corsConfiguration.addAllowedHeader("*");
// 3允许任何方法(post、get等)
corsConfiguration.addAllowedMethod("*");
corsConfiguration.setAllowCredentials(true);
return corsConfiguration;
}
@Bean
public CorsFilter corsFilter() {
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
// 4.添加到全局配置
source.registerCorsConfiguration("/**", buildConfig());
return new CorsFilter(source);
}
}
方式二:可以和拦截器配合使用
package com.adapter;
import com.interceptor.LoginInterceptor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configuration
public class LoginAdapter implements WebMvcConfigurer {
//解决跨域问题
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedHeaders("Content-Type","X-Requested-With","accept,Origin","Access-Control-Request-Method","Access-Control-Request-Headers","token")
.allowedMethods("*")
.allowedOrigins("*")
//是否允许使用cookie
.allowCredentials(true);
}
}
