spring - org.springframework.beans.factory.BeanCreationException : Error creating bean with name 'jedisClientPool' defined in class path resource

Question

我写了一个程序来练习redis。但是当我作为JUnit测试运行时，出现了问题:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jedisClientPool' defined in class path resource [spring/applicationContext-redis.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'jedisPool' of bean class [cn.e3mall.common.jedis.JedisClientPool]: Bean property 'jedisPool' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

这是我的 test:

这里是 applicationContext-redis.xml:

JedisClientPool.java:

package cn.e3mall.common.jedis;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;

    private JedisPool jedisPool;

    @Override

        Jedis jedis = jedisPool.getResource();
        String result = jedis.set(key, value);
        jedis.close();
        return result;
    }

    @Override
    public String get(String key) {
        Jedis jedis = jedisPool.getResource();
        String result = jedis.get(key);
        jedis.close();
        return result;
    }

    @Override
    public Boolean exists(String key) {
        Jedis jedis = jedisPool.getResource();
        Boolean result = jedis.exists(key);
        jedis.close();

    }

    @Override

        String result = jedis.hget(key, field);
        jedis.close();
        return result;
    }

    @Override
    public Long hdel(String key, String... field) {
        Jedis jedis = jedisPool.getResource();
        Long result = jedis.hdel(key, field);
        jedis.close();
        return result;
    }

    @Override
    public Boolean hexists(String key, String field) {
        Jedis jedis = jedisPool.getResource();
        Boolean result = jedis.hexists(key, field);
        jedis.close();
        return result;
    }

    @Override
    public List<String> hvals(String key) {
        Jedis jedis = jedisPool.getResource();
        List<String> result = jedis.hvals(key);
        jedis.close();
        return result;
    }

    @Override
    public Long del(String key) {
        Jedis jedis = jedisPool.getResource();
        Long result = jedis.del(key);
        jedis.close();
        return result;
    }

}

JedisClient.java:

package cn.e3mall.common.jedis;

import java.util.List;

public interface JedisClient {

    String set(String key, String value);
    String get(String key);
    Boolean exists(String key);
    Long expire(String key, int seconds);
    Long ttl(String key);
    Long incr(String key);
    Long hset(String key, String field, String value);
    String hget(String key, String field);
    Long hdel(String key, String... field);
    Boolean hexists(String key,String field);
    List<String> hvals(String key);
    Long del(String key);
}

你能帮我吗？谢谢!!

我在 JedisClientPool 中没有看到 JedisClient 实例的 getter/setter。

一定要创建它们。
