我有一个应用程序在jboss上运行Hibernate4.2.21作为7.2
我们目前有一些@onetoone关系，由于已知的延迟加载的限制，它们总是急切地从相反的方面获取。
为了启用反向关系的延迟加载，我尝试启用构建时字节码插装。
这是我到目前为止所做的。。。
1） 使用激活检测 maven-antrun-plugin （我尝试了hibernate enhance maven插件，但无法使其工作，但这是另一个问题），我现在在构建日志中获得以下maven输出：

[INFO] --- maven-antrun-plugin:1.7:run (Instrument domain classes) @ MyApp-entities ---
[INFO] Executing tasks

instrument:
[instrument] starting instrumentation
[INFO] Executed tasks

2） 接下来，我将所有@onetoone关系注解如下。。。

@OneToOne(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "client", optional=false)
    @LazyToOne(LazyToOneOption.NO_PROXY)
    public ClientPrefs getClientPrefs() {
        return clientPrefs;
    }

    public void setClientPrefs(ClientPrefs clientPrefs) {
        this.clientPrefs = clientPrefs;
    }

3） 然后我加上 implement FieldHandled 到@entity类以及私有字段、getter和setter：

private FieldHandler fieldHandler;

成功…我现在在部署日志中获得以下输出：

15:54:09,720 INFO  [org.hibernate.tuple.entity.EntityMetamodel] (ServerService Thread Pool -- 56) HHH000157: Lazy property fetching available for: uk.co.myapp.entities.Session

15:54:10,054 INFO  [org.hibernate.tuple.entity.EntityMetamodel] (ServerService Thread Pool -- 57) HHH000157: Lazy property fetching available for: uk.co.myapp.entities.Pool
15:54:10,569 INFO  [org.hibernate.tuple.entity.EntityMetamodel] (ServerService Thread Pool -- 56) HHH000157: Lazy property fetching available for: uk.co.myapp.entities.User
15:54:10,624 INFO  [org.hibernate.tuple.entity.EntityMetamodel] (ServerService Thread Pool -- 57) HHH000157: Lazy property fetching available for: uk.co.myapp.entities.User

这些关系现在不再急切地加载…但它们也不懒惰地加载，它们只是默默地返回null。
我已经试着把它移走了 FieldHandled 接口和 FieldHandler 字段，因为我不确定这是否必要，在此之后我不再获得 'HHH000157: Lazy property fetching available for:' 消息，并在默认情况下返回到急切加载状态。
我是不是漏了什么？hibernate文档没有明确说明如何实际设置它
编辑：根据注解添加了ant任务配置：
