Question

我想使用泽西创建一个宁静的网络服务。我有一个由spring + maven + hibernate制作的现有项目。我想使用Hibernate的CRUD方法来创建我的Web服务。

这是我的服务类的代码：

@Component
public class MotServices {

@Autowired
private SessionFactory sessionFactory;

public SessionFactory getSessionFactory() {
    return sessionFactory;
}

public void setSessionFactory(SessionFactory sessionFactory) {
    this.sessionFactory = sessionFactory;
}
@Transactional
public Mot getMotByNom(String nom) {
    Mot mot = new Mot();
    // Acquire session
    Session session = sessionFactory.getCurrentSession();
    try {
        String queryString = "from Mot where nom = :nom";
        Query query = session.createQuery(queryString);
        query.setString("nom", nom);
        mot = (Mot) query.uniqueResult();
    } catch (RuntimeException e) {
        e.printStackTrace();
    } 
    System.out.println(mot);
    return mot;
}
}

这是我的webservice的代码：

@Path("/hello")
public class HelloWS {


@Resource(name="motservices")
private MotServices motservices;

Mot mot = new Mot();


public MotServices getMotservices() {
    return motservices;
}

public void setMotservices(MotServices motservices) {
    this.motservices = motservices;
}

public Mot getMot()
{
    return mot;
}

public void setMot(Mot mot) {
    this.mot = mot;
}
@GET
@Path("/Mot1/mot/{param}")
@Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public Mot getMot(@PathParam("param") String param) {
    try{
         mot = motservices.getMotByNom(param);
    //  mot = motservices.Recherccher("Arbeit", "");
    }
    catch(NullPointerException e)
    {
         mot = new Mot("motAAAA","motBBBB", "motCCCC");         
    }
    return mot;
}
}

但是当我通过此链接调用webservice时的结果＆＃34; http://localhost:8080/Worterbuch/rest/hello/Mot1/mot/Arbeit＆＃34; 我只有一个空值;结果就像这样

<?xml version="1.0" encoding="UTF-8" standalone="true"?>
-<mot>
<definition>motBBBB</definition> 
<example>motCCCC</example>
<id>0</id>
<nom>motAAAA</nom>
</mot>

你知道吗？

这是applicationcontext-web.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"           xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context   http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<!-- This file contains all the imports to other Spring application context 
    files. -->
<import resource="classpath:spring/applicationContext.xml" />


<context:annotation-config />

 <context:component-scan base-package="com.zied.langue.controllers,   com.zied.langue.WS" />



  </beans>
