java使用spring配置jedis及jedis测试

之前项目使用spring进行注入redis，连接需要每调用一次进行连接，所以代码改成直接通过spring初始化连接池，并封装基本的jedis操作，写了一个测试，将医师所有的信息放在hash中，医师信息使用json保存，men集合存放的是性别为男的医师id，women为性别为女的医师，organ集合中存放不同机构下的医师id。查询某机构下的男医师，只需要求该机构和男医师两个set的交集，在hash中查询便可获取数据。具体代码如下：  
redis.config中配置：

##redis数据库的相关配置
    ##连接地址ip
    redis.addr = ip
    ##端口号
    redis.port = 6379
    ##访问密码
    redis.auth = 密码
    ##控制一个pool最多可以有多少个状态为Idle(空)的jedis实例默认值为8
    redis.maxIdle = 200
    ##可用的最大连接实例数 默认为8
    redis.maxActive = 1024
    ##等待可用连接的最大时间单位为毫秒 默认为-1表示永不超时，一旦超过等待时间则直接抛出
    redis.maxWait = 10000
    redis.timeOut = 10000
    ##设置为true则会在borrow一个jedis实例时，提前做validate操作
    redis.testOnBorrow =true
    ##连接最小空闲时间(毫秒)
    redis.minEvictableIdleTimeMillis=1800000
    ##释放连接的扫描间隔（毫秒）
    redis.timeBetweenEvictionRunsMillis=30000
    ##每次释放连接的最大数目
    redis.numTestsPerEvictionRun=1024
    ##最大连接数
    redis.maxTotal=30
    ##在空闲时检查有效性, 默认false 
    redis.testWhileIdle=true
    ##连接耗尽时是否阻塞, false报异常,ture阻塞直到超时, 默认true
    redis.blockWhenExhausted=false

applicationContext.xml中代码：

<context:property-placeholder location="classpath:redis.properties" />
    
        <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
            
            <property name="maxTotal" value="${redis.maxTotal}"/>

            <property name="timeBetweenEvictionRunsMillis" value="${redis.timeBetweenEvictionRunsMillis}"/>

                    .listDoctorBySex("女");
            redisService.savedoctorBySex(doctorAccounts2, "women");
            List<Organ> organs = iOrganService.listOrgan();
            for (int i = 0; i < organs.size(); i++) { 
                List<DoctorAccount> doctorAccounts3 = doctorAccountService
                        .getDoctorAccountsByOrganId(organs.get(i).getOrgan_id());
                redisService.saveOrgan(doctorAccounts3,
                        "organ" + String.valueOf(organs.get(i).getOrgan_id()));
            }
            return null;
        }
    
        @Action("selectDoctor")
        public String selectDoctor() {
            String organId = Struts2Utils.getRequest().getParameter("organId");
            String doctorSex = Struts2Utils.getRequest().getParameter("sex");
            List<Object> doctorAccount = redisService.getDoctorAccount(organId,
                    doctorSex);
            msg.put("doctorAccount", doctorAccount);
            Struts2Utils.renderJson(msg);
            return null;
        }
    }

调用action中的方法就可以保存和查询，因为只是测试，所以代码并不完善，其中的action方法测试能够使用。  
以上代码频繁调用会出现java.net.SocketException: Broken pipe  
redis.clients.jedis.exceptions.JedisConnectionException: java.net.SocketException: Broken pipe  
后来修改将redisdao去掉，直接在service中使用jedis调用，在使用完后及时释放jedis并加线程同步：

@Resource
        private JedisPool jedisPool;
        private Jedis jedis;
        /** * 判断医师是否已被冻结 */
        public synchronized Boolean isPerssion(String doctorId){
            Boolean perssion = null;
            if (jedisPool != null ) {
                    try {
                        jedis = jedisPool.getResource();
                        if (doctorId != null) {
                            perssion = jedis.sismember("NoPerssion", doctorId);
                            jedis.close();;
                        }
                    } catch (Exception e) {
                        e.printStackTrace();
                        throw new BasicRuntimeException(this, "redis判断医师是否已被冻结异常" + e.getMessage());
                    }
                }
            return perssion;
        }
