Question

我的申请

我的applicationContext与WEB_INF / spring / root-context.xml中的root-context.xml一样。它在web.xml中使用

声明

<context:component-scan base-package="com.sat.spring">
    </context:component-scan>   
    <annotation-driven />
    <resources mapping="/resources/**" location="/resources/" />
    <beans:bean     class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <beans:property name="prefix" value="/WEB-INF/views/" />
        <beans:property name="suffix" value=".jsp" />
    </beans:bean>
</beans:beans>

我的调度程序servlet xml位于WEB-INF / spring / appServlet.servlet-context.xml中，其中包含我的

<!-- Root Context: defines shared resources visible to all other web components -->   
    <context:property-placeholder location="classpath:jdbc.properties" />

    <context:component-scan base-package="com.sat.spring">
        <context:exclude-filter expression="org.springframework.stereotype.Controller"
            type="annotation" />
    </context:component-scan>    
    <bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource"
        destroy-method="close">
        <property name="driverClassName" value="${jdbc.driverClassName}" />
        <property name="url" value="${jdbc.databaseurl}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
    </bean>    
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="packagesToScan" value="com.sat.spring.model" />
        <property name="annotatedClasses">
            <list>
                <value>com.sat.spring.model.User</value>
            </list>
        </property>
        <!-- <property name="configLocation"> <props > <prop key="hi"></prop> </props> 
            </property> -->
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.hbm2ddl.auto">hibernate.hbm2ddl.auto</prop>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="show_sql">true</prop>
                <prop key="format_sql">true</prop>
            </props>
        </property>
    </bean>    
    <bean id="transactionManager"           class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>    
    <bean id="persistenceExceptionTranslationPostProcessor"
        class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor">
    </bean>     
    <bean id="userDao" class="com.sat.spring.daoImpl.UserDaoImpl">
    <property name="sessionFactory" ref="sessionFactory"></property>
</bean>    
</beans>

位于WEB-INF / spring文件夹中的我的root-context.xml是：

<body>

 <form:form action="submit" modelAttribute="userForm" method="POST">
        <table>
            <tr>
                <td><form:input path="name" /></td>
                <td><form:label path="name"> Name </form:label></td>
            </tr>
            <tr>
                <td><form:input path="id" /></td>
                <td><form:label path="id"> password </form:label></td>
            </tr>
            <tr>
            <td><form:input path="password" /></td>
            <td><form:label path="password"> password </form:label></td>
            </tr>       
            <tr>
                <td><input type="submit" value="Submit" />      </table>
    </form:form>
</body>

我的登录jsp是

@RequestMapping(value = "/submit", method = RequestMethod.POST)
    public String saveOrUpdateUser(@ModelAttribute("userForm") User user,
            BindingResult result, Model model) {        
        ApplicationContext ac = new FileSystemXmlApplicationContext("WEB-INF/spring/root-context.xml");     
    UserDao dao = (UserDao) ac.getBean("UserDao");      
        Session session;        
        int status = userdao.save(user);    
        System.out.println("----status---" + status);       
        System.out.println("name is: "+user.getName()+ "password is"+user.getPassword());       
        String name = user.getName();
        int id = user.getId();  
        String pw = user.getPassword();     
        model.addAttribute("name", name);   
        model.addAttribute("pw", pw);       
        model.addAttribute("ID", id);       
                return "registered";        
    }

名称，ID和密码中的用户密钥以及login.jsp使用action = / submit

命中mvc控制器

public class UserDaoImpl implements UserDao {
    @Autowired
    private SessionFactory sessionFactory;
    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }
    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }
    public UserDaoImpl() {
    }
    public UserDaoImpl(SessionFactory sessionFactory) {     
        this.sessionFactory = sessionFactory;
    }
    @Transactional
    public int save(User user) {        
         Session session;   
        try {           
            session = sessionFactory.getCurrentSession();           
         session.saveOrUpdate(user);            
        } catch (HibernateJdbcException e) {
            session = sessionFactory.openSession();
        }       
        return 0;
    }
}

我的DaoImpl是

# MYSQL Driver
jdbc.driverClassName =com.mysql.jdbc.Driver
jdbc.databaseurl =jdbc:mysql://localhost:3306/uniprojectdb
jdbc.username=root
jdbc.password=root

我的jdbc.properties文件是

HTTP Status 500 - Request processing failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from file [B:\STS\sts-bundle\sts-3.7.1.RELEASE\WEB-INF\spring\root-context.xml]; nested exception is java.io.FileNotFoundException: WEB-INF\spring\root-context.xml (The system cannot find the path specified

和maven依赖是：

当我运行应用程序时，我转到使用java1.8在Tomcat 7上运行的login.jsp页面。填写login.jsp上的字段后，点击提交按钮后，我得到：

并在控制台上：

fileprivate func getCurrenUserHighResImageURL() -> String? {
    var photoURLOutput : String?
    let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields" : "picture.type(large)"])
    graphRequest.start(completionHandler: { connection, result , error -> Void in

        if ((error) != nil) {
            print("Error: \(error)")
        } else {
            let castedResult = result as? [String : AnyObject]
            if let castedResult = castedResult {

                if let photURL = castedResult["picture"] as? [String : AnyObject] {
                    let photoData = photURL["data"] as? [String : AnyObject]
                    photoURLOutput = photoData?["url"] as? String
                    if let photoURLOutput = photoURLOutput {
                        CURRENT_USER_URL.updateChildValues(["highResImageURL" : "\(photoURLOutput)"])
                    }
                }
            }
        }
    })
    return photoURLOutput
}

我正在使用mySQL数据库但没有保存/持久存在。我做错了什么？请帮忙......谢谢

如果您点击＆＃34;提交＆＃34; - 按钮，则调用方法saveOrUpdateUser()。您构造一个FileSystemXmlApplicationContext指向＆＃34; WEB-INF / spring / root-context.xml＆＃34;那里。但是这个位置评估为＆＃34; B：\ STS \ sts-bundle \ sts-3.7.1.RELEASE \ WEB-INF \ spring \ root-context.xml＆＃34;在运行时期间在您的系统上由于您的应用程序打包在war文件中，因此无法找到文件root-context.xml。

解决方案：

没有必要创建FileSystemXmlApplicationContext，因为已经创建了使用root-context.xml的WebApplicationContext（请参阅您的日志），因为您的web.xml。您应该使用此上下文并让Spring为UserDao（@Autowired）注入依赖项。

applicationContext，classpath和servlet [appServlet]在带有路径的上下文中
