今天完成的事:

       配置好Redis但是进行压测的时候,仅有几十条数据成功剩下的全部error

     判断是连接池的问题

     连接池的配置

#redis的服务器地址
redis.host=127.0.0.1
#redis的服务端口
redis.port=6379
#最大空闲数
redis.maxIdle=400
#最小空闲数
redis.minIdle=0
#链接数据库
redis.default.db=0
#最大连接数
redis.maxTotal=400
#最大建立连接等待时间
redis.maxWaitMillis=200
#指明是否在从池中取出连接前进行检验,如果检验失败,则从池中去除连接并尝试取出另一个
redis.testOnBorrow=true

重写get方法

@Override
public Category get(Category category) {
    Category c = new Category();
    String key = "category_id("+category.getId()+")";
    c = (Category) SerializeUtil.unserialize(jedis.get(key.getBytes()));
    System.out.println("从缓存中读取");
    /**从缓存中读取如果为空则从数据库中读取*/
    if(c == null){
    System.out.println("从数据库中读取");
        c = categoryMapper.get(category);
        if(c != null){
            jedis.set(key.getBytes(), SerializeUtil.serialize(c));  
        }
    }
    return c;
}

崩溃错误

Exception

Root Cause

遇到的困难:

      以上

收获:

     学会配置Redis,感觉腰快断了

明天计划:

     发呆,或者继续做任务
