Redis应用一例（存证数量用计数器实现）

    public Long getCreationCounter() {
        String host =PropertyUtils.getPropertyValue("redis.server.host");
        String port =PropertyUtils.getPropertyValue("redis.server.port");
        String password =PropertyUtils.getPropertyValue("redis.server.password");
        jedis = new Jedis(host,Integer.parseInt(port));
        if(password != null && password.length()>0){
            jedis.auth(password);
        }
        String count = jedis.get(REDIS_COUNT_STROAGEEVIDENCE);
        jedis.close();
        return Long.parseLong(count);
    }

 

<select id="getCount" resultType="long">
    select count(1) from m_storage_evidence
</select>

 

    @Override
    public long getCount() throws ServiceException {
        // TODO Auto-generated method stub
        return stroageEvidenceMapper.getCount();

    }

    @Override
    public void executeStroageEvidenceCount() throws ServiceException {
        // TODO Auto-generated method stub
        Long count = getCount();
        System.out.println(CybMain.properties_version);
        String host =PropertiesUtils.getValueByKey(CybMain.properties_version, "redis.server.host");
        String port =PropertiesUtils.getValueByKey(CybMain.properties_version, "redis.server.port");
        String password = PropertiesUtils.getValueByKey(CybMain.properties_version, "redis.server.password");
        jedis = new Jedis(host,Integer.parseInt(port));
        if(password != null && password.length()>0){
            jedis.auth(password);
        }
        jedis.set("countStroageEvidence", count+"");
        jedis.close();
        
    }
