SpringBoot:配置解决跨域请求

spring boot解决跨域的方式有多种，此文用的是通过增加配置类来解决跨域。

• 项目中增加配置类：CorsConfig.java

package com.yych.zyysys.config.cors;

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
public class CorsConfig {
    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurer() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**")
                        .allowedOrigins("*")
                        .allowCredentials(true)
                        .allowedMethods("GET", "OPTION", "POST", "DELETE", "PUT","PATCH")
                        .allowedHeaders("*")
                        .maxAge(3600);
            }
        };
    }
}
