Question

当我尝试将我的动态Web项目从eclipse发布到apache TomCat时，我收到以下错误：

严重：StandardWrapper.Throwable org.springframework.beans.factory.UnsatisfiedDependencyException：创建名为'roleDAOImpl'的bean时出错：通过字段'sessionFactory'表示的不满意的依赖关系;嵌套异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：没有类型为'org.hibernate.SessionFactory'的限定bean可用：预计至少有1个bean可以作为autowire候选者。依赖注释：{@ org.springframework.beans.factory.annotation.Autowired（required = true）} 在org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor $ AutowiredFieldElement.inject（AutowiredAnnotationBeanPostProcessor.java:592）

我在互联网上搜索但我无法理解为我的类似问题提供的答案。希望有人可以帮助我。

我的web.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
  <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

  <servlet-mapping>
      <servlet-name>Toturial</servlet-name>
      <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

我的Toturial-servlet.xml如下：

    <beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

我的spring-security.xml如下：

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

            <password-encoder hash="plaintext" />
        </authentication-provider>
    </authentication-manager>

</beans:beans>

我的RoleDAO类实现如下：

    package toturial.dao;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import toturial.model.Role;

@Repository
public class RoleDAOImpl implements RoleDAO {

    @Autowired
    private SessionFactory sessionFactory;

    private Session getCurrentSession() {
        return sessionFactory.getCurrentSession();
    }

    public Role getRole(int id) {
        Role role = (Role) getCurrentSession().load(Role.class, id);
        return role;
    }

}

我的TutorialController类实现如下：

    package toturial.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class ToturialController {

    @RequestMapping("/welcome")
    public ModelAndView firstMethod() {
        String message = "<br><div style='text-align:center;'>"
                + "<h3>********** Hello World, Spring MVC Tutorial</h3>This message is coming from CrunchifyHelloWorld.java **********</div><br><br>";
        return new ModelAndView("welcome", "message", message);
    }

    @RequestMapping(value="/sec/moderation", method=RequestMethod.GET)
    public ModelAndView moderatorPage() {
        return new ModelAndView("moderation");
    }

    @RequestMapping(value = "/admin**", method = RequestMethod.GET)
    public ModelAndView adminPage() {

        ModelAndView model = new ModelAndView();
        model.addObject("title", "Spring Security Hello World");
        model.addObject("message", "This is protected page - Admin Page!");
        model.setViewName("admin");

        return model;
    }

    @RequestMapping(value="/admin/first", method=RequestMethod.GET)
    public ModelAndView firstAdminPage() {
        return new ModelAndView("admin-first");
    }

    @RequestMapping(value="/admin/second", method=RequestMethod.GET)
    public ModelAndView secondAdminPage() {
        return new ModelAndView("admin-second");
    }

    @RequestMapping(value="/user-login", method=RequestMethod.GET)
    public ModelAndView loginForm() {
        return new ModelAndView("login-form");
    }

    @RequestMapping(value="/error-login", method=RequestMethod.GET)
    public ModelAndView invalidLogin() {
        ModelAndView modelAndView = new ModelAndView("login-form");
        modelAndView.addObject("error", true);
        return modelAndView;
    }

    @RequestMapping(value="/success-login", method=RequestMethod.GET)
    public ModelAndView successLogin() {
        return new ModelAndView("success-login");
    }
}

我的App.Config类实现如下：

    package toturial.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;
import org.springframework.context.annotation.ImportResource;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate4.HibernateTransactionManager;
import org.springframework.orm.hibernate4.LocalSessionFactoryBean;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.web.servlet.view.UrlBasedViewResolver;


@Configuration
@EnableTransactionManagement
@ComponentScan("tutorial.*")
@PropertySource("classpath:application.properties")
@ImportResource("classpath:spring-security.xml")
@EnableWebMvc
@ComponentScan({ "toturial.*" })
public class AppConfig {

    private static final String PROPERTY_NAME_DATABASE_DRIVER = "db.driver";
    private static final String PROPERTY_NAME_DATABASE_PASSWORD = "db.password";
    private static final String PROPERTY_NAME_DATABASE_URL = "db.url";
    private static final String PROPERTY_NAME_DATABASE_USERNAME = "db.username";

    private static final String PROPERTY_NAME_HIBERNATE_DIALECT = "hibernate.dialect";
    private static final String PROPERTY_NAME_HIBERNATE_SHOW_SQL = "hibernate.show_sql";
    private static final String PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN = "entitymanager.packages.to.scan";

    @Resource
    private Environment env;

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();

        dataSource.setDriverClassName(env.getRequiredProperty(PROPERTY_NAME_DATABASE_DRIVER));
        dataSource.setUrl(env.getRequiredProperty(PROPERTY_NAME_DATABASE_URL));
        dataSource.setUsername(env.getRequiredProperty(PROPERTY_NAME_DATABASE_USERNAME));
        dataSource.setPassword(env.getRequiredProperty(PROPERTY_NAME_DATABASE_PASSWORD));

        return dataSource;
    }

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
        sessionFactoryBean.setDataSource(dataSource());
        sessionFactoryBean.setPackagesToScan(env.getRequiredProperty(PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN));
        sessionFactoryBean.setHibernateProperties(hibProperties());
        return sessionFactoryBean;
    }

    private Properties hibProperties() {
        Properties properties = new Properties();
        properties.put(PROPERTY_NAME_HIBERNATE_DIALECT, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_DIALECT));
        properties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));
        return properties;  
    }

    @Bean
    public HibernateTransactionManager transactionManager() {
        HibernateTransactionManager transactionManager = new HibernateTransactionManager();
        transactionManager.setSessionFactory(sessionFactory().getObject());
        return transactionManager;
    }

    @Bean
    public InternalResourceViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver
                          = new InternalResourceViewResolver();
        viewResolver.setViewClass(JstlView.class);
        viewResolver.setPrefix("/WEB-INF/jsp/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }
}

我的初始化程序类如下：

package toturial.config.core;

import toturial.config.AppConfig;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration.Dynamic;

import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;

public class Initializer implements WebApplicationInitializer {

    public void onStartup(ServletContext servletContext)
            throws ServletException {
        AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
        ctx.register(AppConfig.class);

        servletContext.addListener(new ContextLoaderListener(ctx));

        ctx.setServletContext(servletContext);

        Dynamic servlet = servletContext.addServlet("dispatcher",
                new DispatcherServlet(ctx));
        servlet.addMapping("/");
        servlet.setLoadOnStartup(1);
    }
}

我做错了什么？！任何人都可以帮我解决这个问题。我非常感谢你的时间。
