无法为 HardSoftScoreHibernateType 添加 TypeDef 注释以保留分数

Question

我正在尝试将HardSoftScore保留为整数列，如 https://www.javacodegeeks.com/2015/09/integrating-jpa-hibernate-with-optaplanner.html 中所述。但是，在包含以下语句时，我收到以下错误

import org.optaplanner.persistence.jpa.impl.score.buildin.hardsoft.HardSoftScoreHibernateType;

以添加 TypeDef 注释。

构建时出错

Only a type can be imported. org.optaplanner.persistence.jpa.impl.score.buildin.hardsoft.HardSoftScoreHibernateType resolves to a package

我正在使用kie-wb 7.0.0.Beta6来创建optaplanner项目。

Answer 1

在pom.xml中添加optaplanner-persistence-jpa依赖项，以使用该 JPA 对 OptaPlanner 的支持。

Xstream 是通过 optaplanner-core 的瞬态依赖关系 - 您不必手动添加它。

通常不需要抛弃。

mvn help:effective-pom检查您的有效pom - 您可能继承自某些降级XStream版本等的父pom。还要mvn dependency:tree -Dverbose弄清楚谁在确定 xstream 版本。

Answer 2

下面是我的pom.xml。我只将 kie-maven-plugin 插件版本从 7.0.0-SNAPSHOT(由系统生成)更改为 7.0.0.Beta6，并添加了 optaplanner-persistence-jpa 依赖项。

mvn dependency：tree -dverbose 表明 com.thoughtworks.xstream：xstream：jar：1.4.9 是 org.optaplanner：optaplanner-core 的依赖关系
