原springboot 解决跨域问题

package com.daoshu.involved.shared.core.configurer;

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 implements WebMvcConfigurer {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedOrigins("*")
                .allowCredentials(true)
                .allowedMethods("GET", "POST", "DELETE", "PUT","PATCH")
                .maxAge(3600);
    }
}

使用 tomcat 中的 Filter的方式解决跨域

/**
 * @author zhaopf@mti-sh.cn
 * @Description TODO HttpServletResponse HttpServletResponse 编码全局设置  and 跨域设置
 *
 *
 * springboot 中都能解决跨域的问题，但是在整合shiro后，跨域就失效了。
 *
 * 原因是：shiro的过滤器会在跨域处理之前执行，这就导致未允许跨域的请求先到达shiro过滤器，这样就会出现跨域错误。
 *
 * 解决方案
 * 使用 tomcat 中的 Filter的方式解决跨域
