1.递归查询树形结构
@Override
public List<CategoryEntity> listWithTree() {
//1.查出所有分类
List<CategoryEntity> all = this.list();
//2.组装成父子的属性结构
List<CategoryEntity> level1Menus = all
.stream()
.filter(c -> c.getParentCid().equals(0L))
.map(categoryEntity -> categoryEntity.setChildren(getChildrenCategory(all,categoryEntity.getCatId())))
//大于放后面 升序
.sorted(Comparator.comparing(CategoryEntity::getSort))
.collect(Collectors.toList());
return level1Menus;
}
private List<CategoryEntity> getChildrenCategory(List<CategoryEntity> allList, long pCatId) {
List<CategoryEntity> collect = allList.stream()
.filter(a -> a.getParentCid() == pCatId)
.sorted(Comparator.comparing(CategoryEntity::getSort))
.collect(Collectors.toList());
if (collect.isEmpty()) {
return new ArrayList<>();
} else {
for (CategoryEntity categoryEntity : collect) {
Long catId = categoryEntity.getCatId();
List<CategoryEntity> childrenCategory = getChildrenCategory(allList, catId);
categoryEntity.setChildren(childrenCategory);
}
return collect;
}
}
2.网关统一配置跨域问题
2.1添加 网关过滤器
package com.jmj.gulimall.gateway.config;
import org.springframework.context.annotation.Bean;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.reactive.UrlBasedCorsConfigurationSource;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.reactive.CorsWebFilter;
@Configuration
public class GulimallCorsConfiguration {
//网关gateway是使用webflex 进行编程的 响应式 所以用的都是reactive 包下
@Bean
public CorsWebFilter corsWebFilter() {
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
CorsConfiguration corsConfiguration = new CorsConfiguration();
//1.配置跨域
corsConfiguration.addAllowedHeader("*");//允许哪些头跨域
corsConfiguration.addAllowedMethod("*");//允许哪些请求跨域
corsConfiguration.addAllowedOrigin("*");//允许哪些请求来源 跨域
corsConfiguration.setAllowCredentials(true);//是否允许携带cookie进行跨域 允许 否则跨域请求将会丢失一些相关cookie信息
source.registerCorsConfiguration("/**", corsConfiguration);
return new CorsWebFilter(source);
}
}
但是我们发现还是出现了问题
这是因为网关配置了跨域，而网关转发的微服务也配置了跨域，所以返回了两个响应头被允许，
但是浏览器只希望有一个，所以报错，这时，我们只需要去把微服务的跨域注释掉就好了。
这是人人fast 服务的跨域配置，也是Spring MVC的 配置

package io.renren.config;
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", "PUT", "DELETE", "OPTIONS")
.maxAge(3600);
}
} 
这是网关的路由，是有优先级的，从上优先级最高，如果匹配不上就会依次遍历。
如果不调换优先级，路径会被网关转发到 renrenfast 服务当中，导致没有token 返回invalid token
