如何在Spring Boot中将配置属性注入到Spring Retry注释中?
在spring boot应用程序中,我在yaml文件中定义了一些配置属性,如下所示.
In spring boot application, I define some config properties in yaml file as below.
my.app.maxAttempts = 10
my.app.backOffDelay = 500L
还有一个示例豆
@ConfigurationProperties(prefix = "my.app")
public class ConfigProperties {
private int maxAttempts;
private long backOffDelay;
public int getMaxAttempts() {
return maxAttempts;
}
public void setMaxAttempts(int maxAttempts) {
this.maxAttempts = maxAttempts;
}
public void setBackOffDelay(long backOffDelay) {
this.backOffDelay = backOffDelay;
}
public long getBackOffDelay() {
return backOffDelay;
}
如何将my.app.maxAttempts
和my.app.backOffdelay
的值注入Spring Retry批注?在下面的示例中,我想用相应的配置属性引用替换maxAttempts的值10
和退避值的500L
.
How can I inject the values of my.app.maxAttempts
and my.app.backOffdelay
to Spring Retry annotation? In the example below, I want to replace the value 10
of maxAttempts and 500L
of backoff value with the corresponding references of config properties.
@Retryable(maxAttempts=10, include=TimeoutException.class, backoff=@Backoff(value = 500L))
从 spring-retry-凝视1.2.0 我们可以在@Retryable批注中使用可配置的属性.
Staring from spring-retry-1.2.0 we can use configurable properties in @Retryable annotation.
使用"maxAttemptsExpression",请参考以下代码以使用
Use "maxAttemptsExpression", Refer the below code for usage,
@Retryable(maxAttemptsExpression = "#{${my.app.maxAttempts}}",
backoff = @Backoff(delayExpression = "#{${my.app. backOffDelay}}"))
如果使用低于1.2.0的任何版本,它将不起作用.此外,您不需要任何可配置的属性类.
It will not work if you use any version less than 1.2.0.Also you don't require any configurable property classes.
