# [传智健康全栈项目](https://www.bilibili.com/video/BV1Bo4y117zV?p=9&spm_id_from=pageDriver)

- spring 项目
- mybatis
- dubbo
- ZooKeeper 服务注册中心

环境：java11

## 项目结构

- health_parent：父工程，打包方式为pom，统一锁定依赖的版本，同时聚合其他子模块便于统一执行 maven命令
- health_common：通用模块，打包方式为jar，存放项目中使用到的一些工具类、实体类、返回结果和 常量类
- health_interface：打包方式为jar，存放服务接口
- health_service_provider：Dubbo服务模块，打包方式为war，存放服务实现类、Dao接口、Mapper 映射文件等，作为服务提供方，需要部署到tomcat运行
- health_backend：传智健康管理后台，打包方式为war，作为Dubbo服务消费方，存放Controller、 HTML页面、js、css、spring配置文件等，需要部署到tomcat运行
- health_mobile：移动端前台，打包方式为war，作为Dubbo服务消费方，存放Controller、HTML页 面、js、css、spring配置文件等，需要部署到tomcat运行

## 启动方式

启动两个服务+zookeeper

- health_backend ---> 插件 tomcat7指令 ---> `tomcat7:run` D启动：
- health_service_provider ---> 插件 tomcat7指令 ---> `tomcat7:run` D启动：
- 本地开启 zoopeeker服务 ： D:\Asoftware\apache-zookeeper-3.6.3-bin\apache-zookeeper-3.6.3-bin\bin\zkServer.cmd

### 警告异常

1. Java版本为11时，执行 maven install 会出现非法反射 警告。可以忽略

```bash
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.thoughtworks.xstream.core.util.Fields (file:/C:/Users/dell/.m2/repository/com/thoughtworks/xstream/xstream/1.3.1/xstream-1.3.1.jar) to field java.util.Properties.defaults
WARNING: Please consider reporting this to the maintainers of com.thoughtworks.xstream.core.util.Fields
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release
```

2. [`CheckItemService` 空指针，服务发现错误. 因为 注解@Reference引用的包错了，应该重新引用dubbo提供的注解类](https://blog.csdn.net/qq_38853759/article/details/114763579)

```java
package com.itheima.controller;

import com.alibaba.dubbo.config.annotation.Reference;
import com.itheima.constant.MessageConstant;
import com.itheima.pojo.CheckItem;
import com.itheima.service.CheckItemService;
import com.itheima.utils.Result;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
@RequestMapping("/checkitem")
public class CheckItemController {

    @Reference
    private CheckItemService checkItemService;

    @RequestMapping("/add")
    public Result addItem(@RequestBody CheckItem checkItem) {
        try {
            checkItemService.add(checkItem);

        } catch (Exception e) {
            e.printStackTrace();
            return new Result(false, MessageConstant.ADD_CHECKITEM_FAIL);
        }

        return new Result(false, MessageConstant.ADD_CHECKITEM_SUCCESS);
    }
}

```

3. DAO 找不到 查看 dao接口名与 Mapper 文件的名称一致,xml文件中的 namespace 与 paramtype 是否一样

```bash
[DUBBO] Got unchecked and undeclared exception which called by 192.168.2.29. service: com.itheima.service.CheckItemService, method: add, exception: org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.itheima.dao.CheckItemDao.add, dubbo version: 2.6.0, current host: 127.0.0.1
org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.itheima.dao.CheckItemDao.add
```
