休眠：javax.naming.NoInitialContextException（通过注释进行组件映射）（java休眠函数）

有人可以告诉我为什么出现以下错误吗？

javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial    at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)    at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source)    at javax.naming.InitialContext.getURLOrDefaultInitCtx(Unknown Source)    at javax.naming.InitialContext.getNameParser(Unknown Source)    at org.hibernate.util.NamingHelper.bind(NamingHelper.java:75)    at org.hibernate.impl.SessionFactoryObjectFactory.addInstance(SessionFactoryObjectFactory.java:113)    at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:348)    at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1341)    at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:867)    at com.transbinary.main.Client.main(Client.java:13)

我得到期望的结果，并用数据填充人员表，但出现此错误。

这是我正在使用的代码： Person.java

@Entitypublic class Person implements Serializable {    private Integer id;    private Address homeAddress;    @Id    @GeneratedValue    public Integer getId() {        return id;    }    public void setId(Integer id) {        this.id = id;    }    public Address getHomeAddress() {        return homeAddress;    }    public void setHomeAddress(Address homeAddress) {        this.homeAddress = homeAddress;    }}

地址.java

@Embeddablepublic class Address implements Serializable {    private String city;    private String Country;    public Address() {}     public Address(String city, String country) {        super();        this.city = city;        Country = country;    }    public String getCity() {        return city;    }    public void setCity(String city) {        this.city = city;    }    public String getCountry() {        return Country;    }    public void setCountry(String country) {        Country = country;    }}

hibernate.cfg.xml

<hibernate-configuration> <session-factory name="">  <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>  <property name="hibernate.connection.password">password</property>  <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/mydb</property>  <property name="hibernate.connection.username">root</property>  <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>  <property name="hibernate.hbm2ddl.auto">create</property>  <property name="hibernate.show_sql">true</property>  <property name="hibernate.format_sql">true</property>  <mapping/> </session-factory></hibernate-configuration>

客户端程序

public class Client {    public static void main(String[] args) {                SessionFactory sessionFactory =  new AnnotationConfiguration().configure().buildSessionFactory();        Session session = sessionFactory.openSession();        Transaction txn = session.beginTransaction();        Person person = new Person();        Address homeAddress = new Address("Mumbai", "India");        person.setHomeAddress(homeAddress);        session.save(person);        txn.commit();        session.close();                }}

有人可以帮助我了解我为什么会收到该错误吗？

谢谢。

小编典典

我猜这是由于您在中指定了name属性造成的<session-factory>，因此Hibernate尝试以SessionFactory该名称绑定到JNDI，但是JNDI在您的环境中不可用。因此，删除name属性。

Comm库异常：java.lang.RuntimeException：javax.comm.NoSuchPortException

如何解决Comm库异常：java.lang.RuntimeException：javax.comm.NoSuchPortException？

自两个星期以来，我一直在尝试启动网关服务，并且我引用的是以下提到的代码。说实话，我对此并没有太多想法，

.toPromise().then()

它给我的错误是NoSuchPortException。经检查，我提到的端口已存在，并且已与系统连接。我在另一个系统中运行jar文件。我不明白是什么原因

 public void readLastRecievedMessage(final String modem,final String port,final int bitrate,final String donglenum) throws SMSLibException,TimeoutException,GatewayException,IOException,InterruptedException{
