Question

我知道orphanRemoval中存在hibernate-jpa-2.1-api-1.0.0.Final.jar属性，这是我项目中使用的库。

我添加了Maven依赖：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>4.3.0.Final</version>
</dependency>

我仍然收到错误：The attribute orphanRemoval is undefined for the annotation type OneToMany在行中：

@OneToMany(fetch = FetchType.LAZY, mappedBy = "id.store", cascade = {
        CascadeType.PERSIST, CascadeType.MERGE }, orphanRemoval=true)

这里有什么问题，我该怎么做才能解决这个问题？

编辑：这些是我的依赖项：

    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-server</artifactId>
        <version>${jersey-version}</version>

Answer 1

glassfish web-all依赖项还包含JPA包，它包含旧版本（从2008-04-30开始，因为artefact的版本表示，所以可能是JPA 1.0）。

您可以在此处查看此依赖项中包含的软件包：http://mvnrepository.com/artifact/org.glassfish.distributions/web-all/10.0-build-20080430。

Answer 2

添加了hibernate-jpa-2.0-api-1.0.0.Final.jar并删除了persistence.jar在参考库中的orphanRemoval()包中没有javax.persistence方法的private static List<MyObj> teste; public static List<MyObj> Teste; { get {return Teste;} set { teste.Add(new MyObj{ Value = 1, Quant = 1 }); teste.Add(new MyObj{ Value = 2, Quant = 1 }); teste.Add(new MyObj{ Value = 99, Quant = 1 }); teste.Add(new MyObj{ Value = 33, Quant = 1 }); } }。这解决了错误
