一、只需在添加一下配置,即可解决
package com.liangjian.config; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.*; /** * 解决跨域访问 */ @Configuration public class WebConfig implements WebMvcConfigurer { @Override public void addCorsMappings(CorsRegistry registry) { //设置允许跨域的路径 registry.addMapping("/**") //设置允许跨域请求的域名 .allowedOrigins("*") //是否允许证书 不再默认开启 .allowCredentials(true) //设置允许的方法 .allowedMethods("*") //跨域允许时间 .maxAge(3600); } /** * 跨域配置后swagger2可能不能访问,需要增加如下配置 * @param registry */ @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { registry.addResourceHandler("swagger-ui.html") .addResourceLocations("classpath:/META-INF/resources/"); registry.addResourceHandler("/webjars/**") .addResourceLocations("classpath:/META-INF/resources/webjars/"); } }
