Spring Security：跨域配置

1.在WebSecurityConfigurerAdapter的子类的方法

protected void configure(HttpSecurity http) throws Exception

中增加如下片段：

http.cors().and().    。。。。。。

2.增加如下配置Bean

package com.appbyte.config;


import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configuration(proxyBeanMethods = false)
public class MyCorsConfig {
    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurer() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**");

            }
        };
    }


}
