休眠和彈簧xml配置麻煩

Question

你好傢伙我一直在玩彈簧mvc和冬眠。但是現在，當我嘗試連接hibernate和spring以及XML配置時，出現錯誤。我得到下面這個錯誤：

03-Nov-2015 22:22:19.675 WARNING [RMI TCP Connection(2)-127.0.0.1] org.springframework.web.context.support.XmlWebApplicationContext.refresh Exception encountered during context initialization - cancelling refresh attempt 
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'personService' defined in ServletContext resource [/WEB-INF/services.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/services.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Error accessing stax stream 

我創造了我的web應用程序文件夾中src/main。在我的webapp文件夾中，我創建了WEB-INF文件夾。和WEB-INF文件夾中包含的文件：service.xml，dispatcher-servlet.xml。現在我的hibernate.cfg.xml被放置在src/main文件夾結構中。但是，當我嘗試在加載調度程序時將其添加到service.xml中時，我的hibernate.cfg.xml似乎找不到。有誰知道爲什麼嗎？這是我有麻煩的地方：

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> 
    <property name="dataSource" ref="dataSource" /> 
     <property name="configLocation" value="" /> 
    </bean> 

我似乎無法找到configLocation的值。有沒有人遇到過這個問題。

下面是我的web.xml配置：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" 
     version="3.1"> 
    <display-name>Lab 2</display-name> 
    <context-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value>/WEB-INF/applicationContext.xml, /WEB-INF/services.xml</param-value> 

    </context-param> 
    <listener> 
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
    </listener> 
    <servlet> 
     <servlet-name>dispatcher</servlet-name> 
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 
    <servlet-mapping> 
     <servlet-name>dispatcher</servlet-name> 
     <url-pattern>/</url-pattern> 
    </servlet-mapping> 
</web-app> 

調度-servlet.xml中：

<?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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> 


    <context:component-scan base-package="edu.sjsu.cmpe275.lab2.controller" /> 


     <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping" /> 
     <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter" /> 

     <!-- <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
       <property name="prefix" value="/WEB-INF/views/" /> 
       <property name="suffix" value=".jsp" /> 
     </bean> --> 
</beans> 

service.xml中：

<?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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> 


     <bean name="personService" class="edu.sjsu.cmpe275.lab2.service.PersonImpl" autowire="byName"/> 

     <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" > 
       <property name="driverClassName" value="com.mysql.jdbc.Driver" /> 
       <property name="url" value="jdbc:mysql://localhost:3306/Lab2" /> 
       <property name="username" value="root" /> 
       <property name="password" value="root" /> 
     </bean> 
    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> 
    <property name="dataSource" ref="dataSource" /> 
     <property name="configLocation" value="" /> 
    </bean> 
    <bean name="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager" > 
     <property name="sessionFactory" ref="sessionFactory" /> 
      </bean> 
     <context:component-scan base-package="edu.sjsu.cmpe275.lab2.service" /> 
    <!-- <bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" /> --> 
</beans> 

Answer 1

我通過把hibernate.cfg.xml固定我的錯誤在WEB-INF的根目錄下。這是放在webapp文件夾中並解決了我的問題。

Answer 2

你已經定義了「DataSource」bean，我猜你不需要configLocation屬性。
