递归树形结构获取数据
在注册中心中“product”命名空间中,创建“gulimall-product.yml”配置文件:
将“application.yml”内容拷贝到该配置文件中
server: port: 10000 spring: datasource: #MySQL配置 driverClassName: com.mysql.cj.jdbc.Driver url: jdbc:mysql://192.168.137.14:3306/gulimall_pms?useUnicode=true&characterEncoding=UTF-8&useSSL=false username: root password: root application: name: gulimall-product cloud: nacos: discovery: server-addr: 192.168.137.14:8848 mybatis-plus: global-config: db-config: id-type: auto mapper-locations: classpath:/mapper/**/*.xml
在本地创建“bootstrap.properties”文件,指明配置中心的位置和使用到的配置文件:
spring.application.name=gulimall-product spring.cloud.nacos.config.server-addr=192.168.137.14:8848 spring.cloud.nacos.config.namespace=3c50ffaa-010b-4b59-9372-902e35059232 spring.cloud.nacos.config.extension-configs[0].data-id=gulimall-product.yml spring.cloud.nacos.config.extension-configs[0].group=DEFAULT_GROUP spring.cloud.nacos.config.extension-configs[0].refresh=true
然后启动gulimall-product,查看到该服务已经出现在了nacos的注册中心中了
修改“com.bigdata.gulimall.product.service.CategoryService”类,添加如下代码:
/** * 列表 */ @RequestMapping("/list/tree") public List<CategoryEntity> list(){ List<CategoryEntity> categoryEntities = categoryService.listWithTree(); return categoryEntities; }
测试:http://localhost:10000/product/category/list/tree
