帮我分析代码,并优化,接口性质不变。@Component public class PaymentSnowFlakeIdGenerator { private static UidSoaGenerateService uidSoaGenerateService; @Resource public void setUidSoaGenerateService(UidSoaGenerateService uidSoaGenerateService) { PaymentSnowFlakeIdGenerator.uidSoaGenerateService = uidSoaGenerateService; } public static long generateId64(){ return uidSoaGenerateService.getId(); } }

这段代码定义了一个名为PaymentSnowFlakeIdGenerator的Spring组件,其中包含了一个generateId64()方法用于生成64位ID。这个方法依赖于一个名为UidSoaGenerateService的bean,这个bean用于生成唯一ID。
为了优化这段代码,可以考虑使用构造函数注入来替代set方法注入,避免了可能的线程安全问题,并且更加简洁明了。同时,可以考虑使用final关键字来修饰uidSoaGenerateService变量,以保证其不可变性。下面是优化后的代码:
```
@Component
public class PaymentSnowFlakeIdGenerator {
private final UidSoaGenerateService uidSoaGenerateService;
public PaymentSnowFlakeIdGenerator(@Autowired UidSoaGenerateService uidSoaGenerateService) {
this.uidSoaGenerateService = uidSoaGenerateService;
}
public static long generateId64(){
return uidSoaGenerateService.getId();
}
}
```
这里使用了构造函数注入来注入UidSoaGenerateService的实例,使用@Autowired注解来自动注入bean。同时,将uidSoaGenerateService变量声明为final,以保证其不可变性。这样代码更加简洁明了,也更加安全。
