的JavaFX桌面應用程序 - 使用HSQLDB（嵌入式）和Hibernate

Question

是否有使用HSQLDB，休眠和JavaFX很好的教程。我使用eclipse作爲我的IDE。我的項目模型具有如下定義的變量：

@Id 
@GeneratedValue(strategy = GenerationType.AUTO) 
@Column(name = "PROJECTID") 
private long projectId; 

@Column(name = "PROJECTNAME") 
private final StringProperty projectName; 

@Column(name = "PROJECTJIBP") 
private final StringProperty projectJIBP; 

這是在JavaFX中使用Hibernate的有效方法嗎？

persistance.xml是：

<?xml version="1.0" encoding="UTF-8"?> 

<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" 
    version="2.0" xmlns="http://java.sun.com/xml/ns/persistence"> 
    <persistence-unit name="test" transaction-type="RESOURCE_LOCAL"> 
    <class> handwrittencode.eiar.model.Project</class> 
    <properties> 
     <property name="javax.persistence.jdbc.driver" value="org.hsqldb.jdbcDriver" /> 
     <property name="javax.persistence.jdbc.url" value="jdbc:hsqldb:mem:test" /> 
     <property name="javax.persistence.jdbc.user" value="sa" /> 
     <property name="javax.persistence.jdbc.password" value="" /> 
     <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/> 
     <property name="show_sql" value="true"/> 
     <property name="hibernate.temp.use_jdbc_metadata_defaults" value="false"/> 
    </properties> 
    </persistence-unit> 
</persistence> 

我收到此錯誤信息：

Answer 1

使用具有休眠的這種有效方式JavaFX？

號：使用屬性訪問而非字段訪問：

private final StringProperty projectName; 

@Column(name = "PROJECTNAME") 
public final String getProjectName() { 
    return projectName.get(); 
} 

public final void setProjectName(String projectName) { 
    this.projectName.set(projectName); 
} 

public StringProperty projectNameProperty() { 
    return projectName; 
} 

等等

這使得Hibernate來從返回類型get方法，而不是從確定各類實際字段的類型;所以它可以堅持String而不是StringProperty s，依此類推。
