Come avviato automaticamente RedisTemplate <String,Long>

Question

Desidero utilizzare RedisTemplate per l'avvio a molla. Posso usare StringRedeisTemplate correttamente, ma quando non posso usare RedisTemplate. ecco il codice.

@Service 
public class MyService { 

    @Autowired 
    private RedisTemplate<String, Long> template; 

    public void execute() { 
     template.opsForValue().set("hoge", 1l); 
    } 
} 

Ma, quando avviare le app, ottenere errori.

Answer 1

Lo stacktrace suggeriscono che non è stata definita la Bean che si desidera utilizzare per l'iniezione in RedisTemplate .È possibile risolverlo creando un file di configurazione, ad esempio

import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory; 
import org.springframework.data.redis.core.RedisTemplate; 
import org.springframework.data.redis.serializer.GenericToStringSerializer; 
import org.springframework.data.redis.serializer.StringRedisSerializer; 

@Configuration 
public class AppConfig { 
@Bean 
JedisConnectionFactory jedisConnectionFactory() { 
    return new JedisConnectionFactory(); 
} 

@Bean 
RedisTemplate< String, Long > redisTemplate() { 
    final RedisTemplate< String, Long > template = new RedisTemplate< String, Long >(); 
    template.setConnectionFactory(jedisConnectionFactory()); 
    template.setKeySerializer(new StringRedisSerializer()); 
    template.setHashValueSerializer(new GenericToStringSerializer<Long>(Long.class)); 
    template.setValueSerializer(new GenericToStringSerializer<Long>(Long.class)); 
    return template; 
} 
} 

Una volta ottenuto il file di configurazione allora avete bisogno di passarlo a SpringApplication.run Ad es

Object[] sources = {AppConfig.class}; 
ApplicationContext ctx = SpringApplication.run(sources, args); 

Answer 2

Se si utilizza avvio Primavera, aggiungere una dipendenza in Primavera-boot-starter-Redis, che porterà nel chicco redisTemplate. Tuttavia, che Bean è di tipo RedisTemplate<Object, Object>,

Quindi creare un altro bean per le operazioni di cui avete bisogno, come mostrato qui enter link description here

Answer 3

Si può fare sol4me detto sulla parte superiore, ma è possibile gestire questo in un facile modo:

1, legare auto RedisTemplate

@Autowired 
private RedisTemplate redisTemplate; 

2, valore impostato in questo modo:

redisTemplate.opsForValue().set("yourkey", 12434L); 

3, ottenere il valore in questo modo:

(Long) redisTemplate.opsForValue().get("yourkey"); 

Non c'è bisogno di creare un fagiolo come RedisTemplate< String, Long >, se si esegue questa operazione del genere, si può creare un sacco di fagioli nel vostro sistema. Quindi usa il modo semplice.
