整合thymeleaf渲染页面

将index放到product的资源下的static目录，index.html放到templates文件夹下

导入thymeleaf

<!--  模板引擎--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId></dependency>

关闭缓存，保证开发期间可以实时查看数据

thymeleaf:cache: false

将controller的name修改为app，新建一个web包

重启product服务，访问productr的端口即可

如果访问不到的可以添加

spring:
resources:static-locations: classpath:templates/,classpath:static/

1、添加坐标

2、

${}:取值表达式

<div th:text="${categorys}"></div>

3、

在web中创建IndexController类

@Controller
public class IndexController {@AutowiredCategoryService categoryService;@GetMapping({"/","/index.html"})public String indexPage(Model model){//查询所有的一级分类List<CategoryEntity> categoryEntities= categoryService.getLevel1Categorys();//视图解析器进行分类//classpath:/templates/ +返回值 +.htmlmodel.addAttribute("categorys",categoryEntities);return "index";}}

页面修改不重启服务器实时更新

引入devtools依赖

        <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId><optional>true</optional></dependency>

修改页面后按住ctrl+F9rebuild即可

渲染一级分类数据

<!--轮播主体内容-->
<div class="header_main"><div class="header_banner"><div class="header_main_left"><ul><li th:each="category:${categorys}"><a href="#" class="header_main_left_a" th:attr="ctg-data=${category.catId}"><b th:text="${category.name}">家用电器</b></a></li>

渲染二三级数据

在json包下的catelog.json下返回的数据为

需要模仿这个格式返回查询的数据

创建Vo

@Data
@NoArgsConstructor
@AllArgsConstructor
public class Catelog2Vo {private String catalog1Id;//一级分类的父idprivate List<Catelog3Vo> catalog3List;//三级子分类private String id;private String name;@Data@NoArgsConstructor@AllArgsConstructorpublic  static class Catelog3Vo{private String catalog2Id;private String id;private String name;}
}

在catalogLoader.js中修改请求

在web的IndexController中

@ResponseBody
@GetMapping("/index/catalog.json")
public  Map<String, List<Catelog2Vo>> getCatalogJson(){Map<String, List<Catelog2Vo>> map= categoryService.getCatalogJson();return map;
}

编写 getCatalogJson()方法

@Override
public Map<String, List<Catelog2Vo>> getCatalogJson() {//获取所有Catelog2Vo//1、获取所有一级分类,使用之前的方法getLevel1CategorysList<CategoryEntity> level1Categorys = getLevel1Categorys();//封装为一个mapMap<String, List<Catelog2Vo>> parent_cid = level1Categorys.stream().collect(Collectors.toMap(k -> k.getCatId().toString(), v -> {//根据一级分类id查询二级分类List<CategoryEntity> categoryEntities = baseMapper.selectList(new QueryWrapper<CategoryEntity>().eq("parent_cid", v.getCatId()));List<Catelog2Vo> Catelog2Vos=null;if (categoryEntities!=null){Catelog2Vos = categoryEntities.stream().map(level2Category -> {Catelog2Vo catelog2Vo = new Catelog2Vo(level2Category.getParentCid().toString() , null, level2Category.getCatId().toString(), level2Category.getName());//查找三级分类List<CategoryEntity> categoryEntities1 = baseMapper.selectList(new QueryWrapper<CategoryEntity>().eq("parent_cid", level2Category.getCatId()));List<Catelog2Vo.Catelog3Vo> Catelog3List=null;if (categoryEntities1!=null){Catelog3List = categoryEntities1.stream().map(level3Category -> {Catelog2Vo.Catelog3Vo catelog3Vo = new Catelog2Vo.Catelog3Vo(level2Category.getCatId().toString(), level3Category.getCatId().toString(), level3Category.getName());return catelog3Vo;}).collect(Collectors.toList());}catelog2Vo.setCatalog3List(Catelog3List);return catelog2Vo;}).collect(Collectors.toList());}return Catelog2Vos;}));return parent_cid;
}

测试：

在数据库中将电子书name变为电子书666

nginx-搭建域名访问环境一

使用swithHost添加一个映射

测试：

使用gulimall.com访问虚拟机上的elasticsearch

使用nginx进行反向代理

进入到nginx挂载的conf数据卷中/mydata/nginx/conf/conf.d

现将配置文件复制一份

cp default.conf gulimall.conf

修改gulimall.conf

重启nginx

访问gulimall.com即可访问首页

nginx-搭建域名访问环境二

修改nginx.conf

配置upstream

修改gulimall.conf

监听gulimall.com:80，转发给刚才配置的代理服务器

给网关添加配置信息

注意：主机断言要放在地址断言后面

- id: gulimall_host_routeuri: lb://gulimall-productpredicates:- Host=**.gulimall.com,gulimall.com

nginx代理给网关的时候会丢失host信息

添加配置,使其保存host信息

重启nginx

访问gulimall.com即可访问到首页
