序列号生成器

sequence-spring-boot-starter

spring boot starter依赖

方便在 web 环境下使用 sequence，已上传至 maven 仓库

 <dependency>
    <groupId>com.litong.boot</groupId>
    <artifactId>sequence-spring-boot-starter</artifactId>
    <version>1.0-SNAPSHOT</version>
</dependency>

使用方法

配置文件

cat:
  xsequence:
      #使用基于db的序列号生成器
    db:
      enable: true
      table-name: sys_test123
      retry-times: 3
    #使用基于redis的序列号生成器
    redis:
      enable: true
    #使用基于snowflake的序列号生成器
    snowflake:
      datacenter-id: 0
      worker-id: 0

代码使用

1.使用默认spring注入的三种序列号生成器

@Autowired
private Sequence snowflakeSequence;
@Autowired
private Sequence redisSequence;
@Autowired
private Sequence dbSequence;
@Autowired
private DataSource dataSource;
@GetMapping("/demo")
public String demo() {
    long sno1 = snowflakeSequence.nextValue();
    long sno2 = redisSequence.nextValue();
    long sno3 = dbSequence.nextValue();
    return "success";
}

2.不使用spring注入方式，自定义业务

@Autowired
private DataSource dataSource;
@Autowired
private RedisProperties redisProperties;
@Autowired
private SequenceDbProperties sequenceDbProperties;
@Autowired
private SequenceRedisProperties sequenceRedisProperties;
@GetMapping("/demo")
public String demo() {
    Sequence dbSequence = DbSeqBuilder
                .create()
                .bizName(new DefaultBizName("1"))
                .dataSource(dataSource)
                .step(properties1.getStep())
                .retryTimes(properties1.getRetryTimes())
                .tableName(properties1.getTableName())
                .build();
      Sequence redisSequence = RedisSeqBuilder
                .create()
                .bizName(new DateBizName("3"))
                .ip(redisProperties.getHost())
                .port(redisProperties.getPort())
                .auth(redisProperties.getPassword())
                .step(sequenceRedisProperties.getStep())
                .build();
    long sno2 = redisSequence.nextValue();
    long sno3 = dbSequence.nextValue();
    return "success";
}
