我目前正在尝试休眠以使用 EJB 在我的 postgresql 数据库中发送我的 Java EE 实体。我的实体代码（为了测试，我使用最简单的）是：


import java.io.Serializable;

@Entity

public class Coup implements Serializable {

    private static final long serialVersionUID = 1L;

    @Column(unique=true, nullable=false)
    @Id
    private String name;

    @Column(nullable=false)
    private String jeu;

    public Coup() {
    }

    public Coup(String name, String jeu) {
        this.name = name;
        this.jeu = jeu;
    }

    public String getName() {
        return this.name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getJeu() {
        return this.jeu;
    }

    public void setJeu(String jeu) {
        this.jeu = jeu;
    }

}

and my hibernate.xml file is

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" 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_1_0.xsd">
  <persistence-unit name="PostgresDSjeeux" transaction-type="JTA">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <jta-data-source>java:/PostgresDSjeeux</jta-data-source>
    <class>Equipe</class>
    <class>Joueur</class>
    <class>Salon</class>
    <class>Partie</class>
    <class>HautFait</class>
    <class>Coup</class>
    <properties>

    <!-- <property name="hibernate.connection.driver_class" value="org.postgresql.Driver"/>  -->  
      <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
      <property name="hibernate.show_sql" value="true" />
    <!-- <property name="transaction.factory_class" value="org.hibernate.transaction.JDBCTransactionFactory" /> --> 

    </properties>
  </persistence-unit>
</persistence>

However, after I execute this 

            Coup c = new Coup();
            c.setJeu("superjeu");
            c.setName("supername");
                em.persist(c);

code, the generated query that I see in the JBOSS6 log is : 

14:57:59,364 INFO  [STDOUT] Hibernate: insert into Coup (jeu, name) values (?, ?)

感谢您提供的任何答案。

我认为这只是来自 PreparedStatement 的日志消息，用于显示绑定参数。

您是否查看了数据库以查看插入的内容？这是唯一重要的事情，而不是日志。
