为什么jcabi-aspects注解不起作用

Question

我有这样的代码：

public static void main(String[] args)
{
    testAnnotation();
}

@RetryOnFailure(attempts = 2)
public static void testAnnotation() {
    System.out.println("enter here");
    int x = 1/0;
}

但它只运行函数一次。这是输出：

enter here
Exception in thread "main" java.lang.ArithmeticException: / by zero
at Main.testAnnotation(Main.java:16)
at Main.main(Main.java:10)

这是我的pom：

<dependency>
        <groupId>com.jcabi</groupId>
        <artifactId>jcabi-aspects</artifactId>
        <version>0.22.6</version>
    </dependency>
    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjrt</artifactId>
        <version>1.9.2</version>
        <scope>runtime</scope>
    </dependency>

再加上这个插件：

       <plugin>
            <groupId>com.jcabi</groupId>
            <artifactId>jcabi-maven-plugin</artifactId>

                    </goals>
                </execution>
            </executions>
            <dependencies>
                <dependency>
                    <groupId>org.aspectj</groupId>
                    <artifactId>aspectjtools</artifactId>
                    <version>1.9.2</version>
                </dependency>
                <dependency>
                    <groupId>org.aspectj</groupId>
                    <artifactId>aspectjweaver</artifactId>
                    <version>1.9.2</version>
                </dependency>
            </dependencies>
        </plugin>

除了重试之外，我的程序不能识别任何注释。我怎样才能让它识别注释呢？谢谢

Answer 1

有类似的问题。将注释添加到项目的方法中，并尝试在junit测试中调用它，但当发生模拟异常时，它不会重试。它应该尝试执行两次。

我的方法

@RetryOnFailure(attempts = 2, //
    delay = 5, //
    unit = TimeUnit.SECONDS, //
    types = {DataRequestException.class, HttpHostConnectException.class})
protected String post(final String postContent, final String url, final CloseableHttpClient httpClient,
    final Map<String, String> headers) throws DataRequestException {

    final HttpPost httpPost = new HttpPost(url);
    headers.forEach(httpPost::addHeader);
    httpPost.setEntity(new StringEntity(postContent, StandardCharsets.UTF_8));

    try (final CloseableHttpResponse httpResponse = httpClient.execute(httpPost)) {
        return handleResponse(httpResponse);
    } catch (final DataRequestException e) {
        e.setRequest(postContent);
        throw e;
    } catch (final Exception e) {
        throw new DataRequestException(e, postContent);
    }
}

我的测试

CloseableHttpClient httpClient;

@Before
public void setup() {
    httpClient = Mockito.mock(CloseableHttpClient.class);
}


@Test
public void test() throws ClientProtocolException, IOException {
    assertThrows(DataRequestException.class, () -> {
        Mockito.when(httpClient.execute(Mockito.any(HttpPost.class))).thenThrow(DataRequestException.class);
        new RestRequest().post("", "http://teste.com", httpClient, new HashMap<>());
    });

    Mockito.verify(httpClient, Mockito.times(2)).execute(Mockito.any(HttpPost.class));
}
