@Retryable spring重试注解使用

在类上增加@Retryable注解 application 增加@EnableRetryable注解 value 判断何种报错 maxAttempts指最大重试次数 backoff 为延时时间

代码实例

int i=0;
long startTime = System.currentTimeMillis();

@Retryable(
        value = {Exception.class},
        maxAttempts = 2,
        backoff = @Backoff(delay = 6000)
)
public void dosome(){
    while (true){
        this.a(startTime);
        System.out.println("没报错");
        break;
    }
}



public void a(Long a){
    long endTime = System.currentTimeMillis();
    i++;
    if(endTime - a<5000){
        System.out.println("第"+i+"次调用");
        int v = 1/0;
    }
    System.out.println("第"+i+"次调用");
    System.out.println("成功调用");

}
