Question

我正在尝试编写一个切入点来围绕：com.fasterxml.jackson.databind.DeserializationContext.reportMappingException()方法。

这是我到目前为止所做的事情，而且它不起作用，即maven抱怨：

[WARNING] advice defined in com.charter.aesd.videocatalog.client.interceptor.ContactManagerLogger has not been applied [Xlint:adviceDidNotMatch]
    /Users/rhasija/dev/projects/video/videocatalog-middle/client/src/main/java/com/charter/aesd/videocatalog/client/interceptor/ContactManagerLogger.java:36

试验1：

@Pointcut("execution(* com.fasterxml.jackson.databind.DeserializationContext+.*(..))")
public void servicePointcut() {}

试验2：

@Pointcut("execution( * com.fasterxml.jackson.databind.*.*(..) )")
public void servicePointcut() {}

下面是我的pom.xml。是不是可以通过AspectJ对外部库进行切入点？

Answer 1

您是否尝试过配置maven插件？添加：

<configuration>

  ....

  <weaveDependencies>
    <weaveDependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-databind</artifactId>
    </weaveDependency>
  <weaveDependencies>
<configuration>

Weaving already compiled JAR artifacts

weaveDependencies对应ajc -inpath，请记住它的作用是获取jar文件中的类，将它们展开，然后将它们包含在输出target/classes中。

The AspectJ compiler/weaver

Maven aspectj:compile

您也可以使用加载时编织，在类加载期间将方面指令注入字节代码。

AspectJ切换表达式用于Jackson DeserializationContext reportMappingException
