Eclipselink characterEncoding等价

Question

我在JPA中遇到问题 - EclipseLink characterEncoding问题.我的项目的persistent.xml是;

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
  <persistence-unit name="jpa-1" transaction-type="RESOURCE_LOCAL">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <class>com.usta.jpa1.KITAPLAR</class>
    <properties>
      <property name="javax.persistence.jdbc.url" value="jdbc:derby://localhost:1527/dBase"/>
      <property name="javax.persistence.jdbc.password" value="app"/>
      <property name="javax.persistence.jdbc.driver" value="org.apache.derby.jdbc.ClientDriver"/>
      <property name="javax.persistence.jdbc.user" value="app"/>
      <property name="eclipselink.ddl-generation" value="create-tables"/>
    </properties>
  </persistence-unit>
</persistence>

但是,我运行我的应用程序,保存到我的数据库中的对象,然后我的土耳其字符不能正确显示.我想将编码字符集更改为UTF-8.我找到了;

<property name="hibernate.connection.useUnicode" value="true" />
<property name="hibernate.connection.characterEncoding" value="UTF-8" />

然后找不到eclipseLink等价

看起来 EclipseLink 确实没有用于编码的特定于实现的配置参数：

但是，请确保您的项目是以 UTF-8 格式编译的。检查 Eclipse 是否正确配置：Window->Preferences->General->Workspace 文本文件编码为 UTF-8。另外，如果是这种情况，请将您的 Maven 项目配置为以 UTF-8 进行编译：
