java - ArchUnit：如何避免对 java 类的依赖冲突

Question

我想验证，给定包中的类仅指驻留在包本身中的类。但是我得到了违反，告诉我a类依赖于例如java.lang.String，这对我来说完全没问题。有没有办法忽略基本的java包？

        @ArchTest
        static final ArchRule zeroDependencyOfDomain = noClasses().that()
            .resideInAPackage("..domain..")
            .should().dependOnClassesThat()
            .resideOutsideOfPackages("..domain..");

Answer 1

与其他答案类似，我也没有找到比这更好的方法：

private static final String[] COMMON_PACKAGES = {
    "java..",
    "javax..",
    "com.google..",
    "org.springframework.."};

@ArchTest
final ArchRule classesInProdutPackageNoOutsideAccess =
    classes()
        .that()
        .resideInAnyPackage(PACKAGE_FOO)
        .should()
        .onlyAccessClassesThat()
        .resideInAnyPackage(commonPackagesAnd(PACKAGE_FOO));


private static String[] commonPackagesAnd(String... packages) {
    return ArrayUtils.addAll(packages, COMMON_PACKAGES);
}

Answer 2

您可以显式地允许依赖于 java 包：

@ArchTest
static final ArchRule zeroDependencyOfDomain = noClasses().that()
    .resideInAPackage("..domain..")
    .should().dependOnClassesThat()
    .resideOutsideOfPackages("..domain..", "java..");

您也可以使用classes()and onlyDependOnClassesThat()，在我看来这更容易阅读：

@ArchTest
static final ArchRule zeroDependencyOfDomain = classes().that()
    .resideInAPackage("..domain..")
    .should().onlyDependOnClassesThat()
    .resideInAnyPackage("..domain..", "java..");
