Java @Converter 注释的类没有被 jpa 自动检测到

@Converter annotated class not getting auto detected by jpa

提问by azi

@Converter(introduced since JPA2.1)seems to be a very handy way to switch database values to the value we want to see in our java code. However, I am unable to get this thing working. JPA seems to be unaware to the converter I have written and is trying to convert the values to the appropriate class by itself.

@Converter(introduced since JPA2.1)似乎是将数据库值切换为我们希望在 Java 代码中看到的值的一种非常方便的方法。但是，我无法让这件事发挥作用。JPA 似乎不知道我编写的转换器，并试图自行将值转换为适当的类。

This is the code I have written:

这是我写的代码：

@Converter(autoApply = true)
public class DateConverter implements AttributeConverter<Date, String> {
    @Override
    public String convertToDatabaseColumn(Date b) {
        System.out.println("Converting to Database Columns");
        return "";
    }

    @Override
    public Date convertToEntityAttribute(String string) {
        System.out.println("Converting to Entity Attribute");
        return new Date();
    }
}

Corresponding part written in model is:

model中对应的部分是：

@Entity
@Table(name = "test_table")
public class TestClass extends BaseModel {
    private static final long serialVersionUID = 1L;

    @Id
    private Integer           id;

    @Convert(converter = DateConverter.class)
    @Column(name = "is_dominant_project_unit_type")
    private Date              isDominantProjectUnitType;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public Date getIsDominantProjectUnitType() {
        return isDominantProjectUnitType;
    }

    public void setIsDominantProjectUnitType(Date isDominantProjectUnitType) {
        this.isDominantProjectUnitType = isDominantProjectUnitType;
    }
}

I get the following error when I run the query:

运行查询时出现以下错误：

I have found references to explicitly register the converter in persistence.xml. But, I am not using persistence.xml so far and want to continue this way. My model classes with annotation @Entityare getting detected automatically. This is the code I am using for this:

我找到了在persistence.xml. 但是，到目前为止我还没有使用persistence.xml 并且想继续这种方式。我的带有注释的模型类@Entity会被自动检测到。这是我为此使用的代码：

factory.setPackagesToScan("com.abcd.data.model")

All my @Entityclasses inside this package(or any subpackage) are getting detected. But, not by DateConverter annotated with @Converter. What am I missing here.

我@Entity在这个包（或任何子包）中的所有类都被检测到。但是，不是由 DateConverter 注释的@Converter。我在这里错过了什么。

I have also tried adding the following in properties:

我还尝试在属性中添加以下内容：

Properties properties = new Properties();
properties.put("hibernate.archive.autodetection", "class, hbm");
factory.setJpaProperties(properties);

PS: Please don't get into the details of why I want to convert a random string into date. This is just an example.

PS：请不要深入我为什么要将随机字符串转换为日期的细节。这只是一个例子。

I'm actually not yet familiar with JPA 2.1. However according to your stacktrace you are using hibernate 4.2.1.

我实际上还不熟悉 JPA 2.1。但是，根据您的堆栈跟踪，您使用的是 hibernate 4.2.1。

According to the SO post listed below and the hibernate version list, JPA 2.1 support is added in Hibernate 4.3.0

根据下面列出的 SO 帖子和休眠版本列表，在 Hibernate 4.3.0 中添加了 JPA 2.1 支持

Have you tried updating your version of Hibernate?

您是否尝试过更新您的 Hibernate 版本？

回答by Karol Król

If you decide to configure JPA manually (eg. you want to configure multiple data sources), then LocalContainerEntityManagerFactoryBean should scan package where Converter is placed.

如果您决定手动配置 JPA（例如，您想要配置多个数据源），那么 LocalContainerEntityManagerFactoryBean 应该扫描放置 Converter 的包。

@Bean
LocalContainerEntityManagerFactoryBean yourEntityManagerFactory() {
    final LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();
    factoryBean.setDataSource(arcEditorsDataSource());
    final HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();
    jpaVendorAdapter.setDatabase(Database.POSTGRESQL);
    factoryBean.setJpaVendorAdapter(jpaVendorAdapter);
    factoryBean.setPackagesToScan(
            "your.model",
            "your.jpa.config" //where converter is placed
    );
    return factoryBean;
}
