用ArchUnit限制对静态方法的访问

Question

在我们的体系结构指南中，我们应该只从域模型或存储库实现（在基础结构层）中实例化业务异常

 noClasses().that().resideOutsideOfPackages(DOMAIN).or(areImplementing(Repository.class))
                .should().callMethodWhere(
                target(owner(isAnnotatedWith(BusinessException.class)))
                        .and(target(modifier(JavaModifier.STATIC))));

methods().that().areStatic()
              .and().areDeclaredInClassesThat().areAnnotatedWith(BusinessException.class)
              .should().onlyBeCalled().byClassesThat(areImplementing(Repository.class))

同样，这不会编译，onlybeCalled不存在。

有人有主意吗？

我不完全确定是否有更短的形式来表达您想要的内容，但我相信下面使用自定义谓词的代码片段可以完成这项工作。

noClasses().that()
            // Restriction applies to all classes outside DOMAIN package that are not Repository classes
            .resideOutsideOfPackages(DOMAIN)
            .and()
            .areNotAssignableFrom(Repository.class)
            .should()
            .callMethodWhere(describe("static methods in BusinessExceptions",
                              // Target method may not reside in class annotated with BusinessException
                methodCall -> methodCall.getTarget().getOwner().isAnnotatedWith(BusinessException.class) 
                       // And target method may not have the static modifier
                    && methodCall.getTarget()
                        .resolve()
                        .stream()
                        .anyMatch(m -> m.getModifiers().contains(JavaModifier.STATIC))));

我唯一不确定的一点是methodcall.gettarget().resolve()返回一组JavaMethod类。
