如何配置 AspectJ 以获得编译后编织？我只是在下面的插件中将“编译”替换为“后编译”：（不用说这是不安全的）

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>aspectj-maven-plugin</artifactId>
    <version>1.5</version>
    <configuration>
        <complianceLevel>1.6</complianceLevel>
        <source>1.6</source>
        <target>1.6</target>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>post-compile</goal>
                <goal>test-compile</goal>
            </goals>
        </execution>
    </executions>
</plugin>

但我错过了一些东西，因为它给出了以下错误：

'post-compile' was specified in an execution, but not found in the plugin

【问题讨论】：

您的帖子提到了编译后编织，但被标记为“加载时间编织”。这是两个不同的东西 - 来自文档，"the weaving process itself can take place at one of three different times: compile-time, post-compile time, and load-time."。你追求的是哪一个？

【解决方案1】：

包含要编织的类的 JAR 文件必须在 Maven 项目中列为 <dependencies/>，并在 aspectj-maven-plugin 的 <configuration> 中列为 <weaveDependencies/>。来自http://www.mojohaus.org/aspectj-maven-plugin/examples/weaveJars.html：

<project>
