faktor ips找不到产品组件类
提问于 2022-05-13 12:55:12
我想用Faktor做一个项目，它既是一个模型项目，也是一个产品开发项目。我想用Linkki创建一个UI。以下是我的项目结构：
项目结构 (堆栈溢出不会让我添加图像，我希望链接正常)
在src/main/java文件夹中，是生成linkki的类，而.model.hausrat是faktor为策略组件生成代码的包。
策略组件和产品组件位于rg/linkki_framework/fips/Hausrat_linkki_app/model/internal/faktorips-repository-toc.xml下文件夹src/main/resources中的faktorips存储库-toc.xml中。
它看起来是这样的：

</FaktorIps-TableOfContents>有一次，我尝试获取所有作为HausratProdukt.实例的产品组件的列表就像这样：
private final List<HausratProdukt> produkte;
private IRuntimeRepository repository;
this.repository = PolicyRuntimeRepositoryLookup.getInstance().getRuntimeRepository();

public class PolicyRuntimeRepositoryLookup implements IRuntimeRepositoryLookup {
private static final long serialVersionUID = 1L;
private static final PolicyRuntimeRepositoryLookup SINGLETON = new PolicyRuntimeRepositoryLookup();
private static final String TOC_PATH = "org/linkki_framework/fips/Hausrat_linkki_app/model/internal/faktorips-repository-toc.xml";
//"de/faktorzehn/ipm/core/model/internal/faktorips-repository-toc.xml";
private transient IRuntimeRepository runtimeRepository;
private PolicyRuntimeRepositoryLookup() {
runtimeRepository = ClassloaderRuntimeRepository.create(TOC_PATH);
}
public static PolicyRuntimeRepositoryLookup getInstance() {
return SINGLETON;
}
@Override
public IRuntimeRepository getRuntimeRepository() {
return runtimeRepository;
}
private Object readResolve() {
return SINGLETON;
}
}它在线路上崩溃：

... 60 more我注意到faktorips存储库-toc.xml使用implementationClass保存产品组件，而不管它们是哪个策略类的实例。
例如，HRD-Kompakt2022-1有一个Zusatzdeckungstyp的implementationClass，但是那些实际上是Zusatzdeckungstyp实例的产品组件被保存在toc.xml文件中，它们的实际名称在implementationClass中。
例如，...deckungen.Ueberspannung___2022__01而不是我所期望的...hasurat.HausratZusatzdekungstyp，。
我不知道为什么它只保存这些不同的，或如何改变它，因为这是一个内置的faktor组件。
也许内建方法repository.getAllProductComponents(.)搜索src/main/java文件夹中的类(所有其他类都在其中)，而没有找到这些特定的类，它们位于src/main/resources文件夹中？
但这也是自动生成的，我不知道如何改变它。当然，我可以手动地将类移动到src/main/java文件夹中，但这会使自动生成类的目的落空。有人能帮忙吗？

具体实现类的原因是在这些产品中使用公式。在使用Faktor-IPS公式时，有两个选项：
- 为它们生成和编译Java代码
- 在XML文件中生成Java代码，并在运行时使用Groovy公式计算器解释Java代码
您可以选择在“Faktor-IPS代码生成器设置”中使用的项目选项(右键单击项目->属性-> 'Faktor-IPS代码生成器设置“或.ipsproject文件的XML )。属性“公式编译”可以设置为第一个选项的“子类”或第二个选项的“XML”。默认值“双向”生成内容表条目和Java类，比如第一个选项，以及XML中的Java代码(比如第二个选项)。
在您的项目中使用Maven时，您需要适应所选择的变体。对于变体1，您需要确保src/main/resources中的Java文件也按照https://www.faktorzehn.org/dokumentation/verwendung-von-faktor-ips-projekten-als-maven-dependencies/中的描述进行编译：
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<executions>
<execution>
<id>add-source</id>
<phase>generate-sources</phase>
<goals><goal>add-source</goal></goals>
<configuration>
<sources>
<source>${project.basedir}/derived</source>
</sources>
</configuration>
</execution>
</executions>
</plugin>如果选择第二个选项，则需要向https://mvnrepository.com/artifact/org.faktorips/faktorips-runtime-groovy添加依赖项，并将公式计算器添加到存储库中。
