春季Redis删除不删除密钥

Question

我想删除一个redis键，但由于某种原因它不是删除，但也没有抛出异常。这里是我的代码删除：

import com.example.service.CustomerService; 
import com.example.model.Customer; 

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.data.redis.core.RedisTemplate; 
import org.springframework.stereotype.Service; 

import java.math.BigInteger; 
import java.util.*; 

@Service 
public class RedisCustomerService implements CustomerService { 

    @Autowired 
    private RedisTemplate<String, Object> redisTemplate; 

    private String uniqueIdKey = "customerId"; 

    private BigInteger uniqueId() { 
     long uniqueId = this.redisTemplate.opsForValue().increment(uniqueIdKey, 1); 
     return BigInteger.valueOf(uniqueId); 
    } 

    private String lastNameKey(BigInteger id) { 
     return "customer:ln:" + id; 
    } 

    private String firstNameKey(BigInteger id) { 
     return "customer:fn:" + id; 
    } 

    @Override 
    public void deleteCustomer(BigInteger id) { 
     redisTemplate.opsForValue().getOperations().delete(String.valueOf(id)); 
    } 
} 

Answer 1

没有getOperation使用：

@Override 
public void deleteCustomer(BigInteger id) { 
    redisTemplate.opsForValue().delete(String.valueOf(id)); 
} 

Answer 2

ValueOperations没有删除方法。所以下面将不起作用：

redisTemplate.opsForValue().delete(key); 

尝试

redisTemplate.delete(key); 

Answer 3

试试这个：

public void deleteCustomer(BigInteger id) { 
     redisTemplate.execute(new RedisCallback<String>() { 
       @Override 
       public String doInRedis(RedisConnection redisConnection) throws DataAccessException { 
         redisConnection.del(redisTemplate.getStringSerializer().serialize(String.valueOf(id))); 
         return null; 
       } 
     }); 
}
