　　既然我们看到了注解@Retryable中有这么多参数可以设置，那我们就来介绍几个常用的配置。

@Retryable(include = IllegalAccessException.class, maxAttempts = 5)public void service2() throws IllegalAccessException { log.info("do something... {}", LocalDateTime.now()); throw new IllegalAccessException("manual exception");}

2021-01-06 09:30:11.263 INFO 15612 --- [ main] org.example.RetryService : do something... 2021-01-06T09:30:11.2636219002021-01-06 09:30:12.265 INFO 15612 --- [ main] org.example.RetryService : do something... 2021-01-06T09:30:12.2656291002021-01-06 09:30:13.265 INFO 15612 --- [ main] org.example.RetryService : do something... 2021-01-06T09:30:13.2657012021-01-06 09:30:14.266 INFO 15612 --- [ main] org.example.RetryService : do something... 2021-01-06T09:30:14.2667054002021-01-06 09:30:15.266 INFO 15612 --- [ main] org.example.RetryService : do something... 2021-01-06T09:30:15.266733200

　　java.lang.IllegalAccessException: manual exception....

　　

　　下面来介绍maxAttemptsExpression的设置

@Retryable(value = IllegalAccessException.class, maxAttemptsExpression = "${maxAttempts}")public void service3() throws IllegalAccessException { log.info("do something... {}", LocalDateTime.now()); throw new IllegalAccessException("manual exception");}

maxAttempts: 4

@Retryable(value = IllegalAccessException.class, maxAttemptsExpression = "#{1+1}")public void service3_1() throws IllegalAccessException { log.info("do something... {}", LocalDateTime.now()); throw new IllegalAccessException("manual exception");}@Retryable(value = IllegalAccessException.class, maxAttemptsExpression = "#{${maxAttempts}}")//效果和上面的一样public void service3_2() throws IllegalAccessException { log.info("do something... {}", LocalDateTime.now()); throw new IllegalAccessException("manual exception");}

@Retryable(value = IllegalAccessException.class, exceptionExpression = "message.contains(test)")public void service4(String exceptionMessage) throws IllegalAccessException { log.info("do something... {}", LocalDateTime.now()); throw new IllegalAccessException(exceptionMessage);} @Retryable(value = IllegalAccessException.class, exceptionExpression = "#{message.contains(test)}")public void service4_3(String exceptionMessage) throws IllegalAccessException { log.info("do something... {}", LocalDateTime.now()); throw new IllegalAccessException(exceptionMessage);}

　　但这里值得注意的是, Spring Retry 1.2.5之后exceptionExpression是可以省略掉#{...}

Since Spring Retry 1.2.5, forexceptionExpression, templated expressions (#{...}) are deprecated in favor of simple expression strings (message.contains('this can be retried')).
