Question

我有 Eclipse Maven web项目，我使用 Spring mvc 和 Spring security 。当我试图推出它时，它并没有超越上下文：

Could not open ServletContext resource [/WEB-INF/spring-dispatcher-servlet.xml]

我的问题是当我启动应用程序时出现错误，如

它说找不到/WEB-INF/spring-dispatcher-servlet.xml但是我没有把它放在web.xml中，我的配置文件是app-config.xml

Answer 1

来自Spring reference doc：

的引用

在初始化DispatcherServlet时，Spring MVC在Web应用程序的WEB-INF目录中查找名为[servlet-name] -servlet.xml的文件，并创建在那里定义的bean ...

您的servlet名为spring-dispatcher，因此它会查找/WEB-INF/spring-dispatcher-servlet.xml。您需要具有此servlet配置，并在其中定义与Web相关的bean（如控制器，视图解析器等）。有关servlet上下文与全局应用程序上下文（在您的案例中为app-config.xml）之间关系的说明，请参阅链接文档。

还有一件事，如果你不喜欢servlet config xml的命名约定，你可以明确指定你的配置：

<servlet>
    <servlet-name>spring-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

Answer 2

如果您使用Java配置收到此错误，通常是因为您忘记将应用程序上下文传递给DispatcherServlet构造函数：

AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(WebConfig.class);

ServletRegistration.Dynamic dispatcher = sc.addServlet("dispatcher", 
    new DispatcherServlet()); // <-- no constructor args!
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/*");

通过添加上下文作为构造函数arg来修复它：

AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(WebConfig.class);

ServletRegistration.Dynamic dispatcher = sc.addServlet("dispatcher", 
    new DispatcherServlet(ctx)); // <-- hooray! Spring doesn't look for XML files!
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/*");

确保pom.xml中的maven war插件块在构建战争时包含所有文件（尤其是xml文件）。但是，您不需要包含.java文件。

             <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>2.5</version>                
                <configuration>     
                      <webResources>
                        <resources>
                            <directory>WebContent</directory>
                            <includes>
                              <include>**/*.*</include><!--this line includes the xml files into the war, which will be found when it is exploded in server during deployment -->
                            </includes>
                            <excludes>
                               <exclude>*.java</exclude>
                            <excludes>
                        </resources>                         
                      </webResources>               
                  <webXml>WebContent/WEB-INF/web.xml</webXml>                                    
                </configuration>
            </plugin>

Answer 4

我在WebLogic中遇到此异常，结果证明这是WebLogic中的一个错误。有关详细信息，请参阅此处：Spring Boot exception: Could not open ServletContext resource [/WEB-INF/dispatcherServlet-servlet.xml]

Answer 5

The file name u used spring-dispatcher-servlet.xml
kindly check in web.xml
servlet name as spring-dispatcher at both tag  <servlet> and <servlet-mapping>
in your case it should be

<servlet>
<servlet-name>spring-dispatcher</servlet-name>
<servlet-class></servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>spring-dispatcher</servlet-name>
<url-pattern></url-pattern>
</servlet-mapping>
