二、新版本特性說明

v1.2   支持雪花算法生成序列號

三、使用教程

（1）API使用方式

public class SnowflakeTest_Api {

    private Sequence userSeq;

    @Before
    public void setup() {

        SnowflakeSequence snowflakeSequence = new SnowflakeSequence();
        snowflakeSequence.setDatacenterId(1);
        snowflakeSequence.setWorkerId(2);
        userSeq = snowflakeSequence;
    }

    @Test
    public void test() {
        long start = System.currentTimeMillis();
        for (int i = 0; i < 100; i++) {
            System.out.println("++++++++++id:" + userSeq.nextValue());
        }
        System.out.println("interval time:" + (System.currentTimeMillis() - start));
    }
}

（2）Spring使用方式

xml配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.0.xsd" default-autowire="byName"
       default-lazy-init="false">
    
    <!-- 具體使用demo -->
    <bean id="userSeq" class="com.xuanner.seq.sequence.impl.SnowflakeSequence">
        <property name="workerId" value="1"/>
        <property name="datacenterId" value="2"/>
    </bean>
</beans>

代碼使用

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:snowflake-test.xml" })
public class SnowflakeTest_Spring {

    @Autowired
    private Sequence userSeq;

    @Test
    public void test() {
        for (int i = 0; i < 1000; i++) {
            System.out.println("++++++++++id:" + userSeq.nextValue());
        }
    }

}
