自动装配sessionfactory时出错

Question

我是springmvc的新手，试图学习，我真的坚持这个错误。你可能认为这个问题是重复的，但我搜索了相关的问题，但对我没有用。我得到的错误低于;

从头开始在春天构建Web应用程序非常困难，我浪费了很多时间。什么是我的错，感谢任何帮助，谢谢

Answer 1

在你的web.xml中替换

<context-param>
    <param-name>ApplicationContext</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
...
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/xasweb-dispatcher-servlet.xml</param-value>
</context-param>

通过

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/applicationContext.xml
    </param-value>
</context-param>

您无需单独声明xasweb-dispatcher-servlet.xml，因为容器在web-inf内默认为文件名yourServletName-servlet.xml

还在应用程序上下文xml中添加以下代码，并使用正确的名称空间声明

<context:annotation-config />

或者

<mvc:annotation-driven />

Answer 2

在web.xml替换

中

<context-param>
    <param-name>ApplicationContext</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
...
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/xasweb-dispatcher-servlet.xml</param-value>
</context-param>

通过

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/xasweb-dispatcher-servlet.xml
        /WEB-INF/applicationContext.xml
    </param-value>
</context-param>

仅从上下文参数contextConfigLocation给出的文件中读取配置。
