Spring + AspectJ使用aspectj-maven-plugin编织java 8 [英] Spring + AspectJ weaving for java 8 using aspectj-maven-plugin
问题描述
我正在将我的项目从java 7迁移到java 8，我遇到的问题与使用 aspectj-maven-plugin 的aspectj编织有关。
I'm migrating my project from java 7 to java 8 and the problem I have is related to aspectj weaving using aspectj-maven-plugin.
根据 Haus文档。但问题是我没有找到任何方法来使用（和找到）支持java 8的插件版本7.我看到这里插件7添加了java 8支持，但找不到使用它的方法。
I could configure successfuly the weaving using this plugin running on Java 6 and 7 according to Haus documentation. But the problem is that I haven't found any way to use (and find) plugin version 7 that supports java 8. I saw here that plugin 7 adds java 8 support but couldn't find a way to use it.
这是配置插件我需要：
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<version>1.7</version> <!-- AspectJ weaver plugin 7 is for java 8 (version 1.6 is for java 7) -->
<configuration>
<complianceLevel>1.8</complianceLevel>
<source>1.8</source>
<target>1.8</target>
</configuration>
<executions>
<execution>
<goals>
<goal>compile</goal>
<goal>test-compile</goal>
</goals>
</execution>
</executions>
</plugin>
我确认使用1.6版的上述代码适用于Java 7，但没有运气试图使用版本1.7。
I confirmed that above code using version 1.6 works fine for Java 7, but had no luck trying to use version 1.7.
您知道如何在Java 8上运行spring + aspectj的weaver吗？
Do you know how to run the weaver for spring+aspectj running on Java 8?
推荐答案
2015年9月之前正式发布前的解决方案
之后很多头疼和许多小时都在努力对付这个，幸运的是我可以解决这个问题。这是我做的：
Solution before the official release prior to Sep 2015
After many headaches and many hours struggling against this, fortunately I could solve this problem. Here is what I did:
要使用Java 8我可以配置版本方面的 aspectj-maven-plugin maven-plugin 1.7（注意，aspectj-maven-plugin 1.6适用于Java 7）。
To use aspectj-maven-plugin with Java 8 I could configure version aspectj-maven-plugin 1.7 (Note that aspectj-maven-plugin 1.6 works for Java 7).
因此，maven插件配置必须是：
So, the maven plugin configuration needs to be:
<!-- AspectJ configuration -->
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<version>1.7-SNAPSHOT</version>
<configuration>
<complianceLevel>1.8</complianceLevel>
<source>1.8</source>
<target>1.8</target>
</configuration>
<executions>
<execution>
<goals>
<goal>compile</goal>
<goal>test-compile</goal>
</goals>
</execution>
</executions>
</plugin>
顺便说一句，所需的aspectJ罐子是：
By the way, the aspectJ jars needed are:
<!-- Spring AOP + AspectJ -->
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjrt</artifactId>
<version>1.8.1</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>4.0.4.RELEASE</version>
</dependency>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.8.1</version>
</dependency>
我遇到的最重要的事情是安装aspectj-maven-plugin 1.7 jar I必须手动完成，因为这些jar / pom文件尚未在maven repo上。
The most important thing I've struggled was that to install the aspectj-maven-plugin 1.7 jar I had to do it manually since these jar/pom files aren't on maven repo yet.
更新：因此，jar文件可以是从 Haus Jira 链接下载（查看附件部分）。如果Haus不再可用，你可以从我的github下载：
Update: So, the jar file can be downloaded from Haus Jira link (look at the Attachment section). If Haus is not available anymore you can download it from my github:
https://github.com/fedepia/aspectj-maven-plugin-1.7
下载后将其复制到我当地的仓库我需要在目录中创建拥有 aspectj-maven-plugin-1.7-SNAPSHOT.pom 文件：
After download it and copy it to my local repo I needed to create my own aspectj-maven-plugin-1.7-SNAPSHOT.pom file within the directory:
.m2\repository\org\codehaus\mojo\aspectj-maven-plugin\1.7-SNAPSHOT\aspectj-maven-plugin-1.7-SNAPSHOT.pom
我基于版本1.6的副本但是有修改以下内容：
I based on a copy from version 1.6 but had to modify the following content:
<version>1.7-SNAPSHOT</version>
<properties>
<aspectjVersion>1.8.1</aspectjVersion>
<mavenVersion>2.2.1</mavenVersion>
<changesPluginVersion>2.9</changesPluginVersion>
</properties>
这就是你要去的地方，希望能提供帮助。
That's all here you go, hope to help.
更新：（在评论中添加了Xtreme Biker提供的更多详细信息）
Update: (adding more details as Xtreme Biker asked in the comments)
在我的上下文配置中，我有：
In my context configuration I have:
<aop:aspectj-autoproxy />
<bean id="notificationAspect" class="com.integration.core.aspect.NotificationAspect" factory-method="aspectOf" scope="singleton"></bean>
对于我的java方面，我使用：
For my java aspect I use:
@Aspect
public class NotificationAspect
{
...
@AfterThrowing(pointcut="@annotation(com.integration.core.meta.NotifyOnFailure)", throwing="ex")
public void executeOnException(JoinPoint joinPoint, ExternalApiExecutionException ex) throws Throwable
{
...
最后官方插件自2015年9月发布
这是官方插件版本的答案更新。为了将Java 8与AspectJ一起使用，官方aspectj maven插件可以在以下链接中找到：
Finally official plugin released since Sep 2015
This is an update to the answer with the official plugin release. In order to use Java 8 with AspectJ, the official aspectj maven plugin can be found on this link:
http://www.mojohaus.org/aspectj-maven-plugin/usage.html
以下是maven存储库的链接：
Here is the link to maven repository:
http://mvnrepository.com/artifact/org.codehaus.mojo/aspectj-maven-plugin/1.8
正如文件所述使用它的代码是：
As the documentation stated the code to use it is:
<project>
...
<dependencies>
...
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjrt</artifactId>
<version>1.8.7</version>
</dependency>
...
</dependencies>
...
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<version>1.8</version>
<executions>
<execution>
<goals>
<goal>compile</goal> <!-- use this goal to weave all your main classes -->
<goal>test-compile</goal> <!-- use this goal to weave all your test classes -->
</goals>
</execution>
</executions>
</plugin>
...
</plugins>
<build>
...
</project>
