学习：尚硅谷Java项目之尚庭公寓（4）

五、移动端前后端联调

前端服务

后端服务

全部删除，重新上传

minio要开

Cannot read properties of undefined (reading 'Map')

在rentHouseH5中src\config\config.ts改高德地图 key

查找

地区筛选

价格筛选

排序

个人中心

浏览历史

浏览历史图片加载失败

后端返回的图片 URL 是完整的绝对路径：http://113.141.166.99:9000/lease/...

我的预约

我的租约

确认

六、项目优化

使用 Reids 保存缓存数据

common/src/main/java/org/example/lease/common/redis/RedisConfiguration.java

java 复制代码

package org.example.lease.common.redis;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.RedisSerializer;

@Configuration
public class RedisConfiguration {
    @Bean
    public RedisTemplate<String, Object> stringObjectRedisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        template.setKeySerializer(RedisSerializer.string());
        template.setValueSerializer(RedisSerializer.java());
        return template;
    }
}

编写缓存逻辑

web-app

web/web-app/src/main/java/org/example/lease/web/app/service/impl/RoomInfoServiceImpl.java

java 复制代码

    @Autowired
    private RedisTemplate<String, Object> redisTemplate;

getDetailById方法下

java 复制代码

 public RoomDetailVo getDetailById(Long id) {
        String key = RedisConstant.APP_ROOM_PREFIX + id;
        RoomDetailVo roomDetailVo = (RoomDetailVo) redisTemplate.opsForValue().get(key);
        //1.查询房间信息
        RoomInfo roomInfo = roomInfoMapper.selectById(id);
          if (roomDetailVo == null) {
            //1.查询房间信息
            RoomInfo roomInfo = roomInfoMapper.selectById(id);
            if (roomInfo == null) {
                return null;
            }
               roomDetailVo = new RoomDetailVo();
        ......

        redisTemplate.opsForValue().set(key, roomDetailVo);
    }

编写删除缓存逻辑

web-admin

web/web-admin/src/main/java/org/example/lease/web/admin/service/impl/RoomInfoServiceImpl.java

java 复制代码

@Autowired
private RedisTemplate redisTemplate;

saveOrUpdateRoom方法

java 复制代码

@Override
public void saveOrUpdateRoom(RoomSubmitVo roomSubmitVo) {
    boolean isUpdate = roomSubmitVo.getId() != null;
    super.saveOrUpdate(roomSubmitVo);

    //若为更新操作，则先删除与Room相关的各项信息列表
    if (isUpdate) {
       

        //6.删除原有leaseTermList
        ......

        //7.删除缓存
        redisTemplate.delete(RedisConstant.APP_LOGIN_PREFIX + roomSubmitVo.getId());
    }

  
    ......
}

removeRoomById方法

java 复制代码

@Override
public void removeRoomById(Long id) {

    //1.删除RoomInfo
    ......

    //2.删除graphInfoList
    ......

    //3.删除attrValueList
    ......

    //4.删除facilityInfoList
    ......

    //5.删除labelInfoList
    ......

    //6.删除paymentTypeList
    ......

    //7.删除leaseTermList
    ......

    //8.删除缓存
    redisTemplate.delete(RedisConstant.APP_ROOM_PREFIX + id);
}
