45-51三类分类的操作
吸引⼈的有⼏点
1.⽗⼦节点的查，⼀般都是sql进⾏递归，视频中是⽤⽅法查的，但是有部分代码相似
@Override
public List<CategoryEntity> listWithTree() {
// 查出全部数据
List<CategoryEntity> entities = categoryDao.selectList(null);
//2、组装成⽗⼦的树形结构
List<CategoryEntity> level1Menus = entities.stream().filter(categoryEntity ->
).map((menu)->{
menu.setChildren(getChildrens(menu,entities));
return menu;
}).sorted(Comparatorparing(CategoryEntity::getSort)).List());
return level1Menus;
}
/**
* 说明：把主节点带进来，查到他的⼦节点的同时，再查出⼦节点的下⾯节点
* @param root
* @param all
* @return
*/
public List<CategoryEntity> getChildrens(CategoryEntity root,List<CategoryEntity> all){
List<CategoryEntity> children = all.stream().filter(categoryEntity -> ParentCid() == CatId())
.map(categoryEntity -> {
categoryEntity.setChildren(getChildrens(categoryEntity, all));
return categoryEntity;
}).sorted(Comparatorparing(CategoryEntity::getSort))
.List());
return children;
}
2.就是⽹关的配置，我之前博客也写过
spring:
cloud:
gateway:
routes:
- id: product
uri: lb://gulimall-product
predicates:
- Path=/api/product/**
filters:
-
RewritePath=/api/(?<segment>.*), /$\{segment}
- id: admin_route
uri: lb://renren-fast
predicates:
- Path=/api/**
filters:
- RewritePath=/api/(?<segment>.*), /renren-fast/$\{segment}
3.就是路由转发以后，会有跨域问题，我也写过转发过博客
import t.annotation.Bean;
import t.annotation.Configuration;
import org.s.CorsConfiguration;
import org.s.reactive.CorsWebFilter;
import org.s.reactive.UrlBasedCorsConfigurationSource;
/**
* @author WGR
* @create 2020/5/27 -- 21:54
*/
@Configuration
public class GulimallCorsConfiguration {
@Bean
public CorsWebFilter corsWebFilter(){
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(); CorsConfiguration corsConfiguration = new CorsConfiguration();
//1、配置跨域
corsConfiguration.addAllowedHeader("*");
corsConfiguration.addAllowedMethod("*");
corsConfiguration.addAllowedOrigin("*");
corsConfiguration.setAllowCredentials(true);
return new CorsWebFilter(source);
}
}
mybatisplus的逻辑删除也⽐较简单，底层就是update⽅法，sql打印如下
