我正在嘗試學習如何在服務器上運行Spring MVC項目（在此處仍然很新），並且出現http 404錯誤。我正在使用Eclipse Luna 4.4.1，Java 7，Spring 4.1.4和Windows 7機器上的Pivotal tc server 3.0.2。在我進一步討論之前，讓我說我在使用Tomcat 7創建一個簡單的練習項目時遇到了同樣的404錯誤，所以我認爲問題出在我的服務器配置中（在tc服務器和Tomcat中）。下面是顯示我的項目目錄，我試過運行的服務器和錯誤頁面的屏幕截圖：
在Eclipse項目中獲取HTTP 404錯誤
程序代碼似乎很好。當我運行我的HomeControllerTest（我基本上從Craig Walls的Spring in Action的第四版中獲得）時，它編譯並通過。我還需要考慮解決這個問題嗎？ ` package com.kwalker.practicewellness;
import org.junit.Test;
import org.springframework.test.web.servlet.MockMvc;
import static org.springframework.test.web.servlet.setup.MockMvcBuilders.*;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
import com.kwalker.practicewellness.web.HomeController;
public class HomeControllerTest {
@Test
public void testHomePage() throws Exception {
HomeController controller = new HomeController();
MockMvc mockMvc = standaloneSetup(controller).build();
mockMvc.perform(get("/")).andExpect(view().name("home"));
}
}
` 這裏是HomeController類：
package com.kwalker.practicewellness.web;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class HomeController {
@RequestMapping(value="/", method=RequestMethod.GET)
public String home() {
return "home";
}
}
這裏是WellnessWebAppInitializer：
package com.kwalker.practicewellness.config;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
public class WellnessWebAppInitializer extends
AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class<?>[] { RootConfig.class };
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class<?>[] { WebConfig.class };
}
@Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}
這裏是RootConfig：
package com.kwalker.practicewellness.config;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.ComponentScan.Filter;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
@Configuration
@ComponentScan(basePackages={"practicewellness"},
excludeFilters={@Filter(type=FilterType.ANNOTATION, value=EnableWebMvc.class)})
public class RootConfig {
}
這裏爲W ebConfig：
package com.kwalker.practicewellness.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
@Configuration
@EnableWebMvc
@ComponentScan("practicewellness.web")
public class WebConfig extends WebMvcConfigurerAdapter {
@Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".jsp");
resolver.setExposeContextBeansAsAttributes(true);
return resolver;
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
}
下面是針對home.jsp頁：
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" %>
<html>
<head>
<title>Welcome</title>
<link rel="stylesheet"
type="text/css"
href="<c:url value="/resources/style.css"/>">
</head>
<body>
<h1>
Welcome to Vital Potential!
</h1>
<P> The time on the server is ${serverTime}. </P>
</body>
</html>
這裏是Maven構建輸出：

這裏是控制檯輸出：（只有一個警告，這是他們對我正在觀看的訓練視頻的相同警告，對他們來說運行良好）：

根據上面發佈的代碼，您正在嘗試編寫一個單元測試用例。發佈實際的控制器和你的spring配置文件。 –
同時檢查控制檯，這可能是因爲啓動時出現錯誤，導致整個Web應用程序無法加載。 –
我沒有看到控制檯中會顯示問題的任何內容。控制檯輸出頂部附近的一個警告也出現在我正在觀看的培訓視頻的輸出中，並且在他們運行示例時它們運行良好。我還能看到其他地方嗎？ –
