一、资金记录

（一）后端

TransFlowController

@Api(tags = "资金记录")
@RestController
@RequestMapping("/api/core/transFlow")
@Slf4j
public class TransFlowController {

    @Resource
    private TransFlowService transFlowService;

    @ApiOperation("获取列表")
    @GetMapping("/list")
    public R list(HttpServletRequest request) {
        String token = request.getHeader("token");
        Long userId = JwtUtils.getUserId(token);
        List<TransFlow> list = transFlowService.selectByUserId(userId);
        return R.ok().data("list", list);
    }
}

接口：TransFlowService

List<TransFlow> selectByUserId(Long userId);

 实现：TransFlowServiceImpl

@Override
public List<TransFlow> selectByUserId(Long userId) {

    QueryWrapper<TransFlow> queryWrapper = new QueryWrapper<>();
    queryWrapper
        .eq("user_id", userId)
        .orderByDesc("id");
    return baseMapper.selectList(queryWrapper);
}

（二）前端

脚本pages/user/fund.vue

fetchTransFlowList() {
  this.$axios.$get('/api/core/transFlow/list').then((response) => {
    this.transFlowList = response.data.list
  })
},

二、个人中心

（一）后端

创建VO

@Data
@ApiModel(description = "首页用户信息")
public class UserIndexVO {

    @ApiModelProperty(value = "用户id")
    private Long userId;

    @ApiModelProperty(value = "用户姓名")
    private String name;

    @ApiModelProperty(value = "用户昵称")
    private String nickName;

    @ApiModelProperty(value = "1：出借人 2：借款人")
    private Integer userType;

    @ApiModelProperty(value = "用户头像")
    private String headImg;

    @ApiModelProperty(value = "绑定状态（0：未绑定，1：绑定成功 -1：绑定失败）")
    private Integer bindStatus;

    @ApiModelProperty(value = "帐户可用余额")
    private BigDecimal amount;

    @ApiModelProperty(value = "冻结金额")
    private BigDecimal freezeAmount;

    @ApiModelProperty(value = "上次登录时间")
    private LocalDateTime lastLoginTime;

}

UserInfoController

@ApiOperation("获取个人空间用户信息")
@GetMapping("/auth/getIndexUserInfo")
public R getIndexUserInfo(HttpServletRequest request) {
    String token = request.getHeader("token");
    Long userId = JwtUtils.getUserId(token);
    UserIndexVO userIndexVO = userInfoService.getIndexUserInfo(userId);
    return R.ok().data("userIndexVO", userIndexVO);
}

接口：UserInfoService

UserIndexVO getIndexUserInfo(Long userId);

实现：UserInfoServiceImpl

@Override
public UserIndexVO getIndexUserInfo(Long userId) {
    
    //用户信息
    UserInfo userInfo = baseMapper.selectById(userId);

    //账户信息
    QueryWrapper<UserAccount> userAccountQueryWrapper = new QueryWrapper<>();
    userAccountQueryWrapper.eq("user_id", userId);
    UserAccount userAccount = userAccountMapper.selectOne(userAccountQueryWrapper);

    //登录信息
    QueryWrapper<UserLoginRecord> userLoginRecordQueryWrapper = new QueryWrapper<>();
    userLoginRecordQueryWrapper
        .eq("user_id", userId)
        .orderByDesc("id")
        .last("limit 1");
    UserLoginRecord userLoginRecord = userLoginRecordMapper.selectOne(userLoginRecordQueryWrapper);
    result.put("userLoginRecord", userLoginRecord);

    //组装结果数据
    UserIndexVO userIndexVO = new UserIndexVO();
    userIndexVO.setUserId(userInfo.getId());
    userIndexVO.setUserType(userInfo.getUserType());
    userIndexVO.setName(userInfo.getName());
    userIndexVO.setNickName(userInfo.getNickName());
    userIndexVO.setHeadImg(userInfo.getHeadImg());
    userIndexVO.setBindStatus(userInfo.getBindStatus());
    userIndexVO.setAmount(userAccount.getAmount());
    userIndexVO.setFreezeAmount(userAccount.getFreezeAmount());
    userIndexVO.setLastLoginTime(userLoginRecord.getCreateTime());

    return userIndexVO;
}

（二）前端

pages/user/index.vue

fetchUserData() {
  this.$axios
    .$get('/api/core/userInfo/auth/getIndexUserInfo')
    .then((response) => {
      this.userIndexVO = response.data.userIndexVO
    })
},

三、整合rabbitmq

（一）linux下rabbitmq 的安装

rpm -ivh erlang-21.3.8.9-1.el7.x86_64.rpm

rpm -ivh socat-1.7.3.2-1.el6.lux.x86_64.rpm

rpm -ivh rabbitmq-server-3.8.1-1.el7.noarch.rpm

以上按顺序安装

启用管理插件

rabbitmq-plugins enable rabbitmq_management

启动rabbitmq

systemctl start rabbitmq-server.service

查看后台进程

ps -ef | grep rabbitmq

因为linux下开启rabbitmq，默认的guest账户只能在本地访问，因此我们要新建用户

//添加管理员账户和密码

rabbitmqctl add_user admin 123456

// 分配账号角色
rabbitmqctl set_user_tags admin administrator

// 修改密码（要修改一次密码，否则无法登录）

rabbitmqctl  change_password admin admin

// 查看用户列表

rabbitmqctl  list_users

（二）整合rabbitmq发送短信

1、MQ服务器设置

创建用户 srbuser，配置管理员权限        

创建虚拟机 /srbhost，在Set permission中为新建的用户分配访问虚拟机 /srbhost 和 / 的权限

2、创建rabbit-mq模块

srb下创建rabbit-mq模块并引入依赖

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-amqp</artifactId>
    </dependency>

    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>fastjson</artifactId>
    </dependency>

    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
    </dependency>
</dependencies>

MQConfig

@Configuration
public class MQConfig {

    @Bean
    public MessageConverter messageConverter(){
        //json字符串转换器
        return new Jackson2JsonMessageConverter();
    }
}

 MQConst

public class MQConst {

    public static final String EXCHANGE_TOPIC_SMS = "exchange.topic.sms";//交换机
    public static final String ROUTING_SMS_ITEM = "routing.sms.item";//路由
    public static final String QUEUE_SMS_ITEM  = "queue.sms.item";//消息队列
}

MQService

@Service
@Slf4j
public class MQService {

    @Resource
    private AmqpTemplate amqpTemplate;

    /**
     *  发送消息
     * @param exchange 交换机
     * @param routingKey 路由
     * @param message 消息
     */
    public boolean sendMessage(String exchange, String routingKey, Object message) {
        log.info("发送消息...........");
        amqpTemplate.convertAndSend(exchange, routingKey, message);
        return true;
    }
}

3、service-base中创建SmsDTO

@Data
@ApiModel(description = "短信")
public class SmsDTO {

    @ApiModelProperty(value = "手机号")
    private String mobile;

    @ApiModelProperty(value = "消息内容")
    private String message;
}

4、service-core中发送消息

引入依赖

<!--rabbitmq消息队列-->
<dependency>
    <groupId>com.atguigu</groupId>
    <artifactId>rabbit-mq</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</dependency>

yml配置

  #spring:
  rabbitmq:
    host: 192.168.100.103
    port: 5672
    virtual-host: /srbhost
    username: srbuser
    password: 123456

 根据bindCode获取手机号

UserInfoService接口：

String getMobileByBindCode(String bindCode);

UserInfoServiceImpl实现：

@Override
public String getMobileByBindCode(String bindCode) {
    QueryWrapper<UserInfo> userInfoQueryWrapper = new QueryWrapper<>();
    userInfoQueryWrapper.eq("bind_code", bindCode);
    UserInfo userInfo = baseMapper.selectOne(userInfoQueryWrapper);
    return userInfo.getMobile();
}

 向MQ发送信息：UserAccountServiceImpl 充值回调方法的最后添加发送消息的代码：

@Resource
private UserInfoService userInfoService;
@Resource
private MQService mqService;

@Transactional(rollbackFor = Exception.class)
@Override
public void notify(Map<String, Object> paramMap) {

    log.info("充值成功：" + JSONObject.toJSONString(paramMap));

    ......

    //发消息
    log.info("发消息");
    String mobile = userInfoService.getMobileByBindCode(bindCode);
    SmsDTO smsDTO = new SmsDTO();
    smsDTO.setMobile(mobile);
    smsDTO.setMessage("充值成功");
    mqService.sendMessage(MQConst.EXCHANGE_TOPIC_SMS, MQConst.ROUTING_SMS_ITEM, smsDTO);
}

5、service-sms中监听消息

引入依赖

<!--rabbitmq消息队列-->
<dependency>
    <groupId>com.atguigu</groupId>
    <artifactId>rabbit-mq</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</dependency>

yml配置

  #spring:
  rabbitmq:
    host: 192.168.100.103
    port: 5672
    virtual-host: /srbhost
    username: srbuser
    password: 123456

创建MQ监听器

package com.atguigu.srb.sms.receiver;

@Component
@Slf4j
public class SmsReceiver {

    @Resource
    private SmsService smsService;

    @RabbitListener(bindings = @QueueBinding(
            value = @Queue(value = MQConst.QUEUE_SMS_ITEM, durable = "true"),
            exchange = @Exchange(value = MQConst.EXCHANGE_TOPIC_SMS),
            key = {MQConst.ROUTING_SMS_ITEM}
    ))
    public void send(SmsDTO smsDTO) throws IOException {
        log.info("SmsReceiver 消息监听");
        Map<String,Object> param = new HashMap<>();
        param.put("code", smsDTO.getMessage());
        smsService.send(smsDTO.getMobile(), SmsProperties.TEMPLATE_CODE, param);
    }
}

距尚融宝第一篇博客发布已经过去了一个半月，终于完成了尚融宝这个项目，这个项目主要是在业务上难以理解，后面的投资和放款，还款也涉及多张表的改动，需要保持头脑清晰，理清思路。

接下来继续沉淀，学习一下新的知识，复习旧知识夯实自己的基础。

山高路远，有缘再会！
