我正在开发一个 Spring-MVC 应用程序，我想在其中将 Redis 用于 Redis 键值对中的字符串和整数值。我的意图是在传递字符串时检索整数。当我试图检查我正在尝试的配置是否正确时，我收到了一个错误。

我有 2 个问题，当我尝试运行项目以查看我的配置是否正确时出现错误（错误日志发布在下面）。其次，除了传递XML文件并获取上下文之外，我不知道如何从spring中获取UserAppRegistration实例。这种方法对我不起作用。

错误日志：

组件类。请注意我在服务文件夹中有这个类：

@Component
public class UserAppRegistration {

    @Autowired
    private RedisTemplate<String,Integer> redisTemplate;

    public RedisTemplate<String, Integer> getRedisTemplate() {
        return redisTemplate;
    }

    public void setRedisTemplate(RedisTemplate<String, Integer> redisTemplate) {
        this.redisTemplate = redisTemplate;
    }

}

root-context.xml 中的 Redis 配置：

 <!-- Configuration for Spring-Data-Redis -->
    <beans:bean id="jedisConnFactory"
                class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" p:usePool="true"/>

    <beans:bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate" p:connectionFactory="jedisConnFactory"/>

现在，我想检索 UserAppRegistration 组件以从中推送和拉取值。建议的方式是这样的：

public static UserAppRegistration userAppRegistration;

public static ClassPathXmlApplicationContext context;

static {
   context = new ClassPathXmlApplicationContext("root-context.xml");
      }

出于某种原因，这种方式以前从未对我有用。xml 永远找不到，我尝试了很多路径。如果有更好的选择，我想知道。非常感谢。如果需要更多信息，请告诉我。非常感谢。

这一行是错误的：-

 <beans:bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate" p:connectionFactory="jedisConnFactory"/>

而不是上面它应该是： -

 <beans:bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate" p:connection-factory-ref="jedisConnFactory"/>

您可以检索 UserAppRegistration bean，如下所示：-

UserAppRegistration bean = (UserAppRegistration)context.getBean("userAppRegistration");

从完整路径加载 xml：-

context = new FileSystemXmlApplicationContext("C:/Users/project/root-context.xml");

您也可以在application.properties中配置它：

spring.redis.host=localhost
spring.redis.password=secret
spring.redis.port=6379
