我正在尝试将HardSoftScore作为整数列保留，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
Only a type can be imported. org.optaplanner.persistence.jpa.impl.score.buildin.hardsoft.HardSoftScoreHibernateType resolves to a package
添加TypeDef注释。
构建时出错
$(document).ready(function () {
function reorient(e) {
var orientation = window.screen.orientation.type;
$("body > div").css("-webkit-transform", (orientation == 'landscape-primary' || orientation == 'landscape-secondary') ? "rotate(-90deg)" : "");
}
$(window).on("orientationchange",function(){
reorient();
});
window.setTimeout(reorient, 0);
});
我正在使用kie-wb 7.0.0.Beta6来创建optaplanner项目。
答案 0 :(得分：0)
在optaplanner-persistence-jpa中添加pom.xml依赖项，以便将该jpa支持用于optaplanner。
Xstream是通过optaplanner-core的瞬态依赖 - 您不必手动添加它。
Jettison通常不需要。
请mvn help:effective-pom检查您的有效pom - 您可能会从降低XStream版本等的某个父pom继承。还要mvn dependency:tree -Dverbose确定谁在确定xstream版本。< / p>
答案 1 :(得分：0)
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。
