Spring特性-如何在跨jar项目中公开对象字段:



我正在尝试排除此受影响的类型未暴露给weaver.com.test.as.Thing1（特权访问所需）[Xlint:typeNotExposedToWeaver]

我有两个Spring Roo项目。在"Jar One"中，我有一个具有基本函数的对象：

Thing1.java:

@RooJavaBean
@RooToString
@RooJpaActiveRecord
public class Thing1 {
    private String thingName;
}

Thing1_Roo_JavaBean.aj

privileged aspect Thing1_JsonFields {
    public String Thing1.getThingName() {
        return this.thingName;
    }
    public void Thing1.setThingName(String thingName) {
        this.thingName = thingName;
    }
}

在第二个项目"Jar Two"中，我想扩展Thing1的功能。"Jar Two"将"Jar One"配置为依赖项，并具有以下方面：

privileged aspect Thing1_Translate {
    public String Thing1.toSpanish() {
        return this.thingName;
    }
    public void Thing1.fromSpanish(String thingName) {
        this.thingName = thingName;
    }
}

不过，在Eclipse中，我得到了以下警告：

        this.thingName = thingName;
this affected type is not exposed to the weaver: com.test.as.Thing1 (needed for privileged access) [Xlint:typeNotExposedToWeaver]

在CLI中，mvn package单元测试抱怨找不到"fromSpanish"one_answers"toSpanish"方法。

如何在jar中公开私有元素，以便跨项目子类可以添加/更改基本行为

两个项目之间基本上有一个相同的pom.xml。即：

如果您想编织到另一个JAR或类文件中，后者应该在inpath上，以使其对ajc可见。在AspectJ Maven插件中，分别有weaveDependencies或weaveDirectories等选项。不过，您需要小心编织代码的去向（编译项目的目标目录），以及哪个模块取决于其他哪个项目，因为您编织，然后重新编织等等。

另一种解决方案（可能更好，这取决于您的项目结构）是以另一种方式进行，并将第二个项目添加到第一个项目的aspectpath中。在一个地方完成所有编织，并将方面直接编译到原始JAR中。插件中有一个名为aspectLibraries的参数用于此目的。

无论如何，依赖项目之间必须有一个逻辑链接，否则Java或AspectJ编译器就无法正常工作。
