redis zremove删除不掉
问题未解决
有没有大佬啊~
错误产生
redis zremove删除不掉
我看调试之后
在redis源码中
这个rawKey 和 rawValue
add和remove方法中是一致的
但是remove返回0
@Override
public Boolean add(K key, V value, double score) {
byte[] rawKey = rawKey(key);
byte[] rawValue = rawValue(value);
return execute(connection -> connection.zAdd(rawKey, score, rawValue), true);
}
@Override
public Long remove(K key, Object... values) {
byte[] rawKey = rawKey(key);
byte[][] rawValues = rawValues(values);
return execute(connection -> connection.zRem(rawKey, rawValues), true);
}

方法调用
测试入口
@Test
public void test2() {
System.out.println("1.");
testAddData5();
System.out.println("2.");
testRemoveData5();
}
测试调用
@Test
public void testAddData5(){
EldData eldData=new GeneralData(1.8,60);
eldData.setDate(date);
dataService.addData(userId,action,eldData);
testSearchMap(action);
}
@Test
public void testRemoveData5() {
EldData eldData=new GeneralData(1.8,60);
eldData.setDate(date);
System.out.println(dataService.removeData(userId, eldData));
testSearchMap(action);
}
@Test
public void testSearchMap(String action){
HashMap<String, ArrayList> map = dataService.searchMap(userId,action);
System.out.println(map);
}
Service查询
//返回数据链表
public HashMap<String,ArrayList> searchMap(Integer userId,String action){
HashMap<String,ArrayList> map=new LinkedHashMap<>();
List<EldData> dataList = search(userId,action);
Class<?> dataClass=null;

default: throw new BusinessException(PARAMETER_ERROR,"参数错误");
}
// 获取 EldData 子类的所有被ChineseName注解的属性名
List<String> fieldNames = new ArrayList<>();
Field[] subDataFields = dataClass.getDeclaredFields();
for (Field field : subDataFields) {
//添加是否有注解的判断
ChineseName chineseNameAnnotation = field.getAnnotation(ChineseName.class);
if (chineseNameAnnotation!=null){
fieldNames.add(field.getName());
map.put(field.getAnnotation(ChineseName.class).value(), new ArrayList<>());
}
}
//添加父类EldData的属性

map.put(field.getAnnotation(ChineseName.class).value(), new ArrayList<>());
}
}

}
}
return map;
}
//搜索数据
public List<EldData> search(Integer userId,String action) {
String key= ELD_DATA +action+":"+userId;
Set set = redisTemplate.opsForZSet().reverseRange(key, 0, limit-1);// 获取分数最高的limit个数据
if(set==null){
return new ArrayList<>();
}
ArrayList<EldData> resList = new ArrayList<>(set);
Collections.reverse(resList);
return resList;
}
Service增删改
// 将数据存储到有序集合中，分数为日期的时间戳
public boolean addData(Integer userId, String action,EldData data) {
String key= ELD_DATA + action + ":" + userId;
return redisTemplate.opsForZSet().add(key, data,data.getDate().getTime());
}
// 更新数据，先删除数据，后增加新数据
public boolean updateData(Integer userId,EldData oldData,EldData newData) {
long res=removeData(userId,oldData);
if (res==0){
//没有旧数据，就修改失败
return false;
}
return addData(userId, "",newData);
}
// 删除指定的数据
public long removeData(Integer userId, EldData data) {
String key= ELD_DATA +userId;
return redisTemplate.opsForZSet().remove(key, data);
}

return Objects.equals(HT, that.HT) && Objects.equals(WT, that.WT) && Objects.equals(BMI, that.BMI);
}
@Override

return Objects.hash(super.hashCode(), HT, WT, BMI);
}
}
解决
尝试添加了equals和hashCode()方法，还是解决不了
