How to skip bind properties per profile in spring boot(@ConfigurationProperties, @ConstructorBinding-CodePudding

I want to optionally bind a field to specific class for each profile

the example code is as follows ...

spring:
  config:
    activate:
      on-profile: test1

app:
  cash:
    conn:
      connection-timeout: 1000
      response-timeout: 2000
...

---
spring:
  config:
    activate:
      on-profile: test2

@Getter
@Validated
@ConstructorBinding
@ConfigurationProperties(value = "app.cash.conn")
@RequiredArgsConstructor
public class CashBoxConnectionProperties {

    @NotNull
    @Positive
    private final Integer connectionTimeout;

    @NotNull
    @Positive
    private final Integer responseTimeout;

    @NotNull
    @PositiveOrZero
    private final Integer retryMaxAttempts;

    @NotNull
    @Positive
    private final Integer retryMaxDelay;

}

When running as test1 profile, the application runs normally because the properties value is set, but when running as test2 profile, the error 'Binding to target...' occurs because there is no app.cash.conn properties.

The CashBoxConnectionProperties is not required in test2 profile, so is there any other way than to remove @NotNull annotation?

CodePudding user response：

You can annotate the CashBoxConnectionProperties class with @Profile("test2"), which makes it only available when the test2 profile is active. To make it work, the class should be marked as @Component, since @Profile is only applicable to Spring beans.

For more details check the documentation.

CodePudding user response：

You can use validation groups, to turn off validation for specific fields.

I never used this myself, but you can find an explanation here: https://www.baeldung.com/javax-validation-groups
