调用redis空指针异常
redis.properties 文件放在项目的 resources/custom目录下
redis.host=localhost
redis.port=6379
redis.timeout=2000
redis.database=0
redis类：
@IocBean(name="redis")
@IocBy(args={
"*js", "ioc/",
"*anno", "demo.hello",
"*jedis" // 是的,并没有什么参数
})
public class cust_redis {
@Aop("redis")
public Long getSize() {
return jedis().dbSize();
}
}
调用方法：
public static void main(String[] args) {
System.out.println(new cust_redis().getSize());
}
看了redis.js的实例文件，我这样做可以了
redis.js
var ioc = {
// 参考 https://github.com/xetorthio/jedis/wiki/Getting-started
conf : {
type : "org.nutz.ioc.impl.PropertiesProxy",
fields : {
paths : ["custom/"]
}
},
jedisPoolConfig : {
type : "redis.clients.jedis.JedisPoolConfig",
fields : {
testWhileIdle : true, // 空闲时测试,免得redis连接空闲时间长了断线
maxTotal : {java : "$conf.getInt('redis.maxTotal', 100)"} // 一般都够了吧
}
},
jedisPool : {
type : "redis.clients.jedis.JedisPool",
args : [
{refer : "jedisPoolConfig"},
// 从配置文件中读取redis服务器信息
{java : "$conf.get('redis.host', 'localhost')"},
{java : "$conf.getInt('redis.port', 6379)"},
{java : "$conf.getInt('redis.timeout', 2000)"},
{java : "$conf.get('redis.password')"},
{java : "$conf.getInt('redis.database', 0)"}
],
fields : {},
events : {
depose : "destroy" // 关闭应用时必须关掉呢
}
},
redis : {
type : "org.nutz.integration.jedis.RedisInterceptor",
fields : {
jedisPool : {refer:"jedisPool"}
}
},
redisService : {
type : "org.nutz.integration.jedis.RedisService"
},
pubSubService : {
type : "org.nutz.integration.jedis.pubsub.PubSubService",
fields : {
jedisPool : {refer:"jedisPool"}
},
events : {
depose : "depose"
}
}
};
public static Ioc ioc;
private static final Log log = Logs.getLog(bind_ppv_asset.class);
static {
ioc = new NutIoc(new JsonLoader("ioc/jedis.js"));
}
public static void main(String[] args) {
RedisService redisService = ioc.get(RedisService.class, "redisService");
System.out.println(redisService.dbSize());
}
```
