Java 后台解决与前端的跨域问题

在deploy模块的config包里，添加CorsConfig类

import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.CorsRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;@Configurationpublic class CorsConfig extends WebMvcConfigurerAdapter {@Overridepublic void addCorsMappings(CorsRegistry registry) {registry.addMapping("/**").allowedOrigins("*").allowCredentials(true).allowedMethods("GET", "POST", "DELETE", "PUT","OPTIONS").maxAge(3600);}}

搞定~~
