RedisCacheConfig.java:
@Bean(name="jedisConnectionFactory")
JedisConnectionFactory jedisConnectionFactory() {
JedisConnectionFactory factory = new JedisConnectionFactory();
return factory;
}
@Bean
RedisTemplate<String, Object> redisTemplate() {
RedisTemplate<String, Object> redisTemplate = new RedisTemplate<String, Object>();
redisTemplate.setConnectionFactory(jedisConnectionFactory());
return redisTemplate;
}
工具類:
@SuppressWarnings("unchecked")
@Component
public class RedisUtil {
@SuppressWarnings("rawtypes")
@Autowired
private RedisTemplate redisTemplate;
public void test() {
redisTemplate.opsForValue().set("q", 123);//这里的redisTemplate=null 不知为何?
}
}
呼叫test()方法 報java.lang.NullPointerException 求指點明燈
你用的是springboot集成,單元測試卻是junit的,沒有納入springboot的環境,當然是有問題的了。
