SpringFramework和Hibernate应用程序HTTP状态404 Java

时间：2016-03-01 11:30:42

标签： java spring hibernate

我正在尝试编写一个Web应用程序。我已经用hibernate建立了一个数据库，我用3层写了应用程序 - dao，service和controller。项目编译，但当我在浏览器中打开网址时，我有 - HTTP状态404 - / ticket-system / person / home。我没有例外。我将在这里复制代码。

当我尝试在eclipse中打开 http://localhost:8080/ticket-system/prson/home 时，我发出此警告 - 警告：找不到带URI的HTTP请求的映射[/ ticket-system / prson / home]在DispatcherServlet中，名称为“app-config”

控制器 

@Controller
@RequestMapping("/person")
public class PersonController {

    @Autowired
    private PersonService personService;

    @RequestMapping(value = "/home")
    public ModelAndView home() {
        List<Person> listUsers = personService.list();
        ModelAndView model = new ModelAndView("home");
        model.addObject("personList", listUsers);
        return model;
    }

}

DaoImpl 

@Repository("personDao")
public class PersonDaoImpl implements PersonDao {

    @Autowired
    private SessionFactory sessionFactory;

    @Override
    @Transactional
    public List<Person> list() {
        @SuppressWarnings("unchecked")
        List<Person> listUser = (List<Person>) sessionFactory.getCurrentSession().createCriteria(Person.class)
                .setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY).list();

        return listUser;
    }

}

ServiceImpl 

@Service("personService")
public class PersonServiceImpl implements PersonService {

    @Autowired
    private PersonDao personDao;

    @Override
    public List<Person> list() {
        return personDao.list();
    }


}

2 个答案:

答案 0 :(得分：1)

/ticket-system/person/home未映射到任何网址，因为您在下面的web.xml中提到了这一点：

<servlet-mapping>
        <servlet-name>app-config</servlet-name>
        <url-pattern>*.html</url-pattern>
    </servlet-mapping>

将其更改为

<servlet-mapping>
            <servlet-name>app-config</servlet-name>
            <url-pattern>*</url-pattern>
        </servlet-mapping>

答案 1 :(得分：0)

您的servlet名为app-config，配置文件的名称为app-config.xml。默认情况下，Spring正在类路径中查找<servlet-name>-servlet.xml文件。因此，将配置文件重命名为app-config-servlet.xml

然后将servlet-mapping更改为

<servlet-mapping>
    <servlet-name>app-config</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

此外，您应在@RequestMapping中指定HTTP方法

@RequestMapping(value = "/home", method = RequestMethod.GET)
public ModelAndView home() {
    List<Person> listUsers = personService.list();
    ModelAndView model = new ModelAndView("home");
    model.addObject("personList", listUsers);
    return model;
}

然后尝试访问http://localhost:8080/ticket-system/person/home

应用程序的上下文根是ticket-system对吗？
