我正在使用Spring,Hibernate和Maven配置工具編寫MVC應用程序。但是,一旦我試圖通過在eclipse maven install建立我的代碼,我不斷收到錯誤Maven安裝錯誤找不到符號addServlet

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project SampleMVCApp: Compilation failure 
[ERROR] /C:/newworkspace/SampleMVCApp/src/com/javacodegeeks/configuration/AppInitializer.java:[19,56] cannot find symbol 
[ERROR] symbol: method addServlet(java.lang.String,org.springframework.web.servlet.DispatcherServlet) 

這裏是我的AppInitializer.java

package com.sampleapp.configuration; 

import javax.servlet.ServletContext; 
import javax.servlet.ServletException; 
import javax.servlet.ServletRegistration; 

import org.springframework.web.WebApplicationInitializer; 
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext; 
import org.springframework.web.servlet.DispatcherServlet; 

public class AppInitializer implements WebApplicationInitializer { 

    @Override 
    public void onStartup(ServletContext container) throws ServletException { 
     AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext(); 
     ctx.register(AppConfig.class); 
     ctx.setServletContext(container); 

     ServletRegistration.Dynamic servlet = container.addServlet("dispatcher", new DispatcherServlet(ctx)); 

     servlet.setLoadOnStartup(1); 
     servlet.addMapping("/"); 

    } 
} 

這裏是我的pom.xml文件

不知道我在哪裏將javax.servlet-api多次。

我猜問題是Servlet的API包含在依賴層次多次嘗試MVN依賴:樹並找到該servlet-API快到了,排除他們這樣的例子,

<dependency> 
 
      <groupId>org.springframework</groupId> 
 
      <artifactId>spring-web</artifactId> 
 
      <version>${springframework.version}</version> 
 
    <exclusions> 
 
     <exclusion> 
 
      <groupId>javax.servlet</groupId> 
 
      <artifactId>servlet-api</artifactId> 
 
     </exclusion> 
 
    </exclusions> 
 

 
</dependency>
