在我们系统研发过程中经常需要发送短信、邮件、站内信等，笔者在本文给大家介绍下如何使用Oinone的消息模块。

准备工作

如果通过我们工程脚手架工具生成的则已经引入了无需做更多的配置，如果不是则需要按以下步骤先配置依赖和增加启动模块

pamirs-demo-boot的pom文件中引入pamirs-message-core包依赖

<dependency>
  <groupId>pro.shushi.pamirs.core</groupId>
  <artifactId>pamirs-message-core</artifactId>
</dependency>

pamirs-demo-boot的application-dev.yml文件中增加配置pamirs.boot.modules增加message，即在启动应用中增加message模块

pamirs:
    boot:
    modules:
      - message

消息参数设置

发送邮件和短信需要设置对应的发送邮箱服务器和短信云，短信目前默认阿里云短信。我们通过代码示例来完成对应邮箱和短信的参数设置

Step1 增加pamirs-message-api依赖

pamirs-demo-core的pom文件中引入pamirs-message-api包依赖

<dependency>
  <groupId>pro.shushi.pamirs.core</groupId>
  <artifactId>pamirs-message-api</artifactId>
</dependency>

Step2 消息参数设置

请自行替换邮箱服务器和短信通道的账号信息

消息发送举例

该例子以各种站内信、邮件、短信方式发送宠物商品库存记录信息为例，构建宠物商品库存信息发送服务并在宠物商品库存模型的表格页面创建发送入口

Step1 创建宠物商品库存信息发送服务接口

在Api工程新建PetItemInventoryMessageService接口，并定义发送站内信、邮件、短信的三个Function

package pro.shushi.pamirs.demo.api.service;

import pro.shushi.pamirs.demo.api.model.PetItemInventroy;
import pro.shushi.pamirs.meta.annotation.Fun;
import pro.shushi.pamirs.meta.annotation.Function;

@Fun(PetItemInventoryMessageService.FUN_NAMESPACE)
public interface PetItemInventoryMessageService {

    String FUN_NAMESPACE = "demo.PetItemInventoryMessageService";
    @Function
    void sendMail(PetItemInventroy data);
    @Function
    void sendEmail(PetItemInventroy data);
    @Function
    void sendSms(PetItemInventroy data);

}

Step2 发送站内信

在Core工程新建PetItemInventoryMessageService接口的实现类

package pro.shushi.pamirs.demo.core.service;

        } catch (Exception e) {
            // TODO: 可增加失败业务处理
            throw PamirsException.construct(DemoExpEnumerate.SYSTEM_ERROR, e).appendMsg("站内信发送失败").errThrow();
        }
    }

    @Override
    @Function
    public void sendEmail(PetItemInventroy data) {
        //发送一个邮件
        List<String> receiveEmails = new ArrayList<>();

        receivePhoneNumbers.add("13777899044");//接收手机号，自行提供 FIXME 

        //目前支持阿里云短信通道：获取短信模板，如没有短信模板，需要先创建模板，并审核通过

            // TODO: 可增加失败业务处理
        }
    }
}

Step3 为宠物商品库存模型的表格页面新增发送入口

把以下代码复制到PetItemInventroyAction类中

@Autowired
private PetItemInventoryMessageService petItemInventoryMessageService;
@Action(displayName = "发送站内信",bindingType = ViewTypeEnum.TABLE,contextType = ActionContextTypeEnum.SINGLE)
public PetItemInventroy sendMail(PetItemInventroy data) {
    petItemInventoryMessageService.sendMail(data);
    return data;
}

/**
 * 发送邮件
 */
@Action(displayName = "发送邮件",bindingType = ViewTypeEnum.TABLE,contextType = ActionContextTypeEnum.SINGLE)
public PetItemInventroy sendEmail(PetItemInventroy data){
    petItemInventoryMessageService.sendEmail(data);
    return data;
}

/**
 * 发送短息
 */
@Action(displayName = "发送短信",bindingType = ViewTypeEnum.TABLE,contextType = ActionContextTypeEnum.SINGLE)
public PetItemInventroy sendSms(PetItemInventroy data){
    petItemInventoryMessageService.sendSms(data);
    return data;
}

Step4 重启看效果

请分别点击发送邮件、发送短信、发送站内信测试效果，自行测试效果
