1、前沿

折腾了一天，终于把xsequence的jar发布到maven上去了。之后就有动力开始，维护一些文档，并不断的升级完善这个组件喽。以后每次升级一次版本都会维护一份文档，说明一些新的特性和使用方式。

2、源码地址

https://gitee.com/xuan698400/xsequence

3、Maven支持

com.xuanner

xsequence-core

1.0

4、DB方式使用说明

(1)API方式使用

public class SequenceTest_Api {

private com.xuanner.seq.sequence.Sequence userSeq;

@Before

public void setup() {

//数据源

DruidDataSource dataSource = new DruidDataSource();

dataSource.setUrl("jdbc:mysql://121.196.218.206:3306/admin?characterEncoding=UTF-8");

dataSource.setUsername("admin");

dataSource.setPassword("xxx");

dataSource.setMaxActive(300);

dataSource.setMinIdle(50);

dataSource.setInitialSize(2);

dataSource.setMaxWait(500);

//利用DB获取区间管理器

DbSeqRangeMgr dbSeqRangeMgr = new DbSeqRangeMgr();

dbSeqRangeMgr.setDataSource(dataSource);

dbSeqRangeMgr.setTableName("sequence");

dbSeqRangeMgr.setRetryTimes(100);

dbSeqRangeMgr.setStep(100);

dbSeqRangeMgr.setStepStart(0);

dbSeqRangeMgr.init();

//构建序列号生成器

DefaultRangeSequence defaultRangeSequence = new DefaultRangeSequence();

defaultRangeSequence.setName("user");

defaultRangeSequence.setSeqRangeMgr(dbSeqRangeMgr);

userSeq = defaultRangeSequence;

}

@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配置

第一步：配置spring的xml文件：

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">

第二步：直接在代码里面就可以使用了

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations = { "classpath:seq-test.xml" })

public class SequenceTest_Spring {

@Autowired

private Sequence userSeq;

@Test

public void test() {

for (int i = 0; i < 1000; i++) {

System.out.println("++++++++++id:" + userSeq.nextValue());

}

}

}
