Wildfly 14.0集成AspectJ无日志输出问题求助

我在基础HelloWorld Servlet项目中尝试使用AspectJ，部署到WildFly 14.0后，控制台看不到MyAspect类的日志输出，不确定是代码还是WildFly配置需要调整。相关代码和项目结构如下：

MyAspect类 #

@Aspect
public class MyAspect {

    static Logger logger = Logger.getLogger("MyAspect");

    @Before("execution(* org.jboss.as.quickstarts.helloworld.HelloService.*(..))")
    public void testModeOnlyMethods() {
        logger.info("AspectLog");
    }
} 

HelloWorldServlet类 #

public class HelloWorldServlet extends HttpServlet {

    static String PAGE_HEADER = "<html><head><title>helloworld</title></head><body>";

    static String PAGE_FOOTER = "</body></html>";

    @Inject
    HelloService helloService;

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        resp.setContentType("text/html");
        PrintWriter writer = resp.getWriter();
        writer.println(PAGE_HEADER);
        writer.println("<h1>" + helloService.createHelloMessage("World") + "</h1>");
        writer.println(PAGE_FOOTER);
        writer.close();
    }

}

HelloService类 #

public class HelloService {

    static Logger logger = Logger.getLogger("HelloService");

    String createHelloMessage(String name) {
        logger.info("Aspect");
        return "Hello " + name + "!";
    }
}

项目结构 #

│   ├── main/
│   │   ├── java/
│   │   │   └── org/
│   │   │       └── jboss/

│   │   │               └── quickstarts/

要让AspectJ在WildFly 14.0中生效，需从代码配置、依赖管理和容器配置三方面调整：

1. 代码调整 #

• 给MyAspect添加CDI注解（如@Named），让容器管理切面类：

@Aspect
@Named
public class MyAspect {
    // 原有代码不变
}

• 修改HelloService的createHelloMessage方法为public修饰符，AspectJ默认对非public方法的拦截支持有限：

public String createHelloMessage(String name) {
    // 原有代码不变
}

2. 依赖配置 #

在pom.xml中添加AspectJ核心依赖：

<dependencies>
    <!-- 其他依赖 -->
    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjrt</artifactId>
        <version>1.9.6</version>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjweaver</artifactId>
        <version>1.9.6</version>
    </dependency>
</dependencies>

3. WildFly容器配置 #

• 开启AspectJ模块全局可见：编辑WILDFLY_HOME/standalone/configuration/standalone.xml，找到<subsystem xmlns="urn:jboss:domain:ee:4.0">节点，添加：

<global-modules>
    <module name="org.aspectj.aspectjrt" slot="main"/>
</global-modules>

• 若WildFly中无AspectJ模块，需手动创建：
  1. 创建目录WILDFLY_HOME/modules/system/layers/base/org/aspectj/aspectjrt/main
  2. 在该目录下新建module.xml：

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="org.aspectj.aspectjrt">
    <resources>
        <resource-root path="aspectjrt-1.9.6.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.annotation.api"/>
        <module name="javax.ejb.api"/>
        <module name="javax.servlet.api"/>
    </dependencies>
</module>

3. 将aspectjrt-1.9.6.jar放入上述目录

4. 编译时织入（可选） #

若采用编译时织入，在pom.xml的<build>节点下添加AspectJ Maven插件：

<plugins>
    <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>aspectj-maven-plugin</artifactId>
        <version>1.14.0</version>
        <executions>
            <execution>
                <goals>
                    <goal>compile</goal>
                    <goal>test-compile</goal>
                </goals>
            </execution>
        </executions>
        <configuration>
            <source>1.8</source>
            <target>1.8</target>
            <aspectLibraries>
                <aspectLibrary>
                    <groupId>org.aspectj</groupId>
                    <artifactId>aspectjrt</artifactId>
                </aspectLibrary>
            </aspectLibraries>
        </configuration>
        <dependencies>
            <dependency>
                <groupId>org.aspectj</groupId>
                <artifactId>aspectjtools</artifactId>
                <version>1.9.6</version>
            </dependency>
        </dependencies>
    </plugin>
</plugins>
