## Distributed lock
### Features
- [x] High performance.
- [x] No deadlock.
- [x] Support Redis cluster, single.
- [x] Non-blocking lock.
- [x] blocking lock.
- [x] Support connection pool.
- [x] Suppport Spring4.x+.
### Quick start
maven dependency:
```xml
top.crossoverjie.opensource
distributed-redis-tool
1.0.4
```
Set bean:
```java
@Configuration
public class RedisLockConfig {
private Logger logger = LoggerFactory.getLogger(RedisLockConfig.class);
@Autowired
private JedisConnectionFactory jedisConnectionFactory;
@Bean
public RedisLock build() {
RedisLock redisLock = new RedisLock.Builder(jedisConnectionFactory,RedisToolsConstant.SINGLE)
.lockPrefix("lock_")
.sleepTime(100)
.build();
return redisLock;
}
}
```
#### Non-blocking lock:
```java
@Autowired
private RedisLock redisLock ;
public void use() {
String key = "key";
String request = UUID.randomUUID().toString();
try {
boolean locktest = redisLock.tryLock(key, request);
if (!locktest) {
System.out.println("locked error");
return;
}
//do something
} finally {
redisLock.unlock(key,request) ;
}
}
```
#### Blocking lock
```java
redisLock.lock(String key, String request);
```
#### Blocking lock, Custom block time
```java
redisLock.lock(String key, String request,int blockTime);
```

## Distributed limiting
### Features
- [x] High performance.
- [x] native API.
- [x] Annation API.
- [x] Support Redis cluster, single.
- [x] Suppport Spring4.x+
### Quick start
maven dependency:
```xml
top.crossoverjie.opensource
distributed-redis-tool
1.0.4
```
1. Set bean:
```java
@Configuration
public class RedisLimitConfig {
private Logger logger = LoggerFactory.getLogger(RedisLimitConfig.class);
@Value("${redis.limit}")
private int limit;
@Autowired
private JedisConnectionFactory jedisConnectionFactory;
@Bean
public RedisLimit build() {
RedisLimit redisLimit = new RedisLimit.Builder(jedisConnectionFactory, RedisToolsConstant.SINGLE)
.limit(limit)
.build();
return redisLimit;
}
}
```
2. Scan packages.
```java
@ComponentScan(value = "com.crossoverjie.distributed.intercept")
# RedisLimitConfig's package
@ComponentScan(value = "xx.xxx.config")
```
#### Native API:
```java
boolean limit = redisLimit.limit();
if (!limit){
res.setCode(StatusEnum.REQUEST_LIMIT.getCode());
res.setMessage(StatusEnum.REQUEST_LIMIT.getMessage());
return res ;
}
```
Other apis:
#### @CommonLimit
```java
@CommonLimit
@RequestMapping("/xx")
public void anyMethod(){}
```
#### @SpringControllerLimit
If you are using native Spring:
```java
@SpringControllerLimit(errorCode = 200,errorMsg = "request has limited")
@RequestMapping("/createOptimisticLimitOrderByRedis/{sid}")
@ResponseBody
public String createOptimisticLimitOrderByRedis(@PathVariable int sid) {
logger.info("sid=[{}]", sid);
int id = 0;
try {
id = orderService.createOptimisticOrderUseRedis(sid);
} catch (Exception e) {
logger.error("Exception",e);
}
return String.valueOf(id);
}
```
Spring xml:
```xml
```
It can be used for any methods.
