Java 在名为的DispatcherServlet中找不到URI为[]的HTTP请求的映射

java eclipse spring servlets

Java 在名为的DispatcherServlet中找不到URI为[]的HTTP请求的映射,java,eclipse,spring,servlets,Java,Eclipse,Spring,Servlets,我在SpringWebServices上做示例，当我运行这个示例时，我发现下面的错误在名为“springrest”的DispatcherServlet中找不到URI为[/SpringRestfulWebServicesExample/]的HTTP请求的映射 web.xml <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/

我在SpringWebServices上做示例，当我运行这个示例时，我发现下面的错误

在名为“springrest”的DispatcherServlet中找不到URI为[/SpringRestfulWebServicesExample/]的HTTP请求的映射

web.xml

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >
 <web-app>
  <display-name>Archetype Created Web Application</display-name>
  <servlet>  
  <servlet-name>springrest</servlet-name>  
<servlet-class>  
 org.springframework.web.servlet.DispatcherServlet

</servlet>  
<servlet-mapping>  
<servlet-name>springrest</servlet-name>  
<url-pattern>/*</url-pattern>  
</servlet-mapping>  
</web-app>

在springrest-servlet.xml中，我得到以下错误

1. cvc-elt.1: Cannot find the declaration of element 'beans'
2. Multiple annotations found at this line:
- schema_reference.4: Failed to read schema document   'http://www.springframework.org/schema/context/spring-context-3.0.xsd', because    1) could 
 not find the document; 2) the document could not be read; 3) the root   element of the document is not <xsd:schema>.
- cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'context:component-scan'.

如何解决这些问题。欢迎提供任何帮助。

将您的

springrest

servlet url模式更改为以下任一模式

/SpringRestfulWebServicesExample/*

或

/

因为带有

/*

的servlet url模式将匹配

 http://<ip>:<port>/*

还要将这些依赖项添加到pom中，然后重试：

 <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-beans</artifactId>
    <version>${spring.version}</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>${spring.version}</version>
</dependency>


org.springframework
春豆
${spring.version}
org.springframework
spring上下文
${spring.version}

问题在于您在

src>main>资源中放置了java文件的项目结构
您需要将其放置在src>main>java
您请求的url是什么？@Tom Sebastian我也收到错误cvc elt.1:在springrest-servlet.xml中找不到元素“beans”的声明更改模式后url是否有效？@allDroid查看我的更新。它是一个xml工作副本，显示了相同的错误，因此我无法运行服务器进行上述更改后，您是否可以触发maven构建并在tomcat webapps中手动部署生成的war文件，然后运行以查看eclipse是否存在问题
