spring java配置問題：拒絕的bean名稱'requestMappingHandlerMapping'：沒有標識的URL路徑

Question

我使用spring java configs來創建一個web應用程序。

當我在Tomcat上運行它說，資源/ MYAPP/MYAPP沒有找到

在控制檯輸出我注意到以下。我不確定這是否導致任何問題。

我只顯示那些奇怪的日誌行。作爲日誌這麼大

這裏是WebAppContextConfig.java

package com.example; 

import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.ComponentScan; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.web.servlet.config.annotation.EnableWebMvc; 
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry; 
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; 
import org.springframework.web.servlet.view.InternalResourceViewResolver; 

@Configuration 
@EnableWebMvc 
@ComponentScan(basePackages = "com.example") 
public class WebAppContextConfig extends WebMvcConfigurerAdapter{ 
//Resolve logical view names to .jsp resources in /WEB-INF/views directory 

@Bean 
public InternalResourceViewResolver configureInternalResourceViewResolver() { 
    InternalResourceViewResolver resolver = new InternalResourceViewResolver(); 
    resolver.setPrefix("WEB-INF/jsp/"); 
    resolver.setSuffix(".jsp"); 
    return resolver; 
} 

@Override 
public void addResourceHandlers(ResourceHandlerRegistry registry) { 
    registry.addResourceHandler("/scripts/**").addResourceLocations("/scripts/"); 
    registry.addResourceHandler("/css/**").addResourceLocations("/css/"); 
    registry.addResourceHandler("/images/**").addResourceLocations("/images/"); 
} 
} 

這裏是WebAppInitializer.java

package com.example; 

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

import org.springframework.context.annotation.ComponentScan; 
import org.springframework.web.WebApplicationInitializer; 
import org.springframework.web.context.ContextLoaderListener; 
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext; 
import org.springframework.web.servlet.DispatcherServlet; 
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer; 

public class WebAppInitializer implements WebApplicationInitializer { 

/* (non-Javadoc) 
* @see org.springframework.web.WebApplicationInitializer#onStartup(javax.servlet.ServletContext) 
*/ 
@Override 
public void onStartup(ServletContext servletContext) throws ServletException { 
    AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext(); 
    rootContext.register(WebAppContextConfig.class); 
    servletContext.addListener(new ContextLoaderListener(rootContext)); 

     AnnotationConfigWebApplicationContext dispatcherContext = 
       new AnnotationConfigWebApplicationContext(); 
       dispatcherContext.register(WebAppContextConfig.class); 

    ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispatcher", new DispatcherServlet(rootContext)); 
    dispatcher.setLoadOnStartup(1); 
    dispatcher.addMapping("/"); 


    DefaultServletHandlerConfigurer defaultConfig = new DefaultServletHandlerConfigurer(servletContext); 
    defaultConfig.enable(); 

} 

} 

也有基於任何好地方查找Java春天mvc配置？

感謝

這不是根本原因@ravi，但我看到，我想強調，開始有幾個問題：

一個。您似乎通過ContextLoaderListener和Dispatcher servlet兩次加載Spring Java Config文件，只通過ContextLoaderListener執行它，您可以用這種方式定義您的DispatcherServlet - 只需加載一個空的上下文（理想情況下有兩個java配置 - 一個用於核心應用，另一個用於網絡配置）：

ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispatcher", new GenericWebApplicationContext()); 
dispatcher.setLoadOnStartup(1); 
dispatcher.addMapping("/"); 

b。你可以用log4j啓用調試模式，看看還有什麼記錄 - 如果沒有足夠的信息，請在跟蹤級別登錄。

c。內部視圖解析器路徑看起來有點不對勁 - 你缺少前進「/」：

resolver.setPrefix("/WEB-INF/jsp/"); 

能否請您嘗試以下，看看你現在看到什麼。
