弹簧：如何将供应商函数<String>作为构造函数注入

Question

我已经对这个类进行了编码：

@Component
public class AuditFactory {
private Supplier<String> auditIdSupplier;
public AuditFactory(Supplier<String> auditIdSupplier) {
this.auditIdSupplier = auditIdSupplier;
}
}

它被用作@Service类的依赖项：

@Service
public class AuditService {
private AuditFactory auditFactory;
public AuditService(AuditFactory auditFactory) {
this.auditFactory = auditFactory;
}
}

当注入AuditFactory时，我如何告诉Spring注入Supplier<String>？

编辑

@Bean
public Supplier<String> auditIdSupplier(FrontOfficeProperties frontOfficeProperties) {
return () -> String.join(
"-",
frontOfficeProperties.getCpdId(),
frontOfficeProperties.getRedisAuditKeyPrefix(),
UUID.randomUUID().toString()
);
}

其中CCD_ 4是CCD_。

下面的方法可能会帮助您解决问题。你也可以分享供应商类。

@Component
public class AuditFactory {
private Supplier<String> auditIdSupplier;
public AuditFactory(Supplier<String> auditIdSupplier) {
this.auditIdSupplier = auditIdSupplier;
}
}

@Service
public class AuditService {
private AuditFactory auditFactory;
public AuditService(AuditFactory auditFactory) {
this.auditFactory = auditFactory;
}
}
