Maven Dependencies和webapp文件夹没有部署到Eclipse中的目标文件夹？

为了直截了当，我遇到的问题是，当我使用Spring Boot运行Spring Web Application时，我在转到localhost时收到以下消息：8080 

2014-03-11 18:56:31.614  WARN 7640 --- [nio-8080-exec-3] o.s.web.servlet.PageNotFound             : No mapping found for HTTP request with URI [/WEB-INF/views/index.jsp] in DispatcherServlet with name 'dispatcherServlet'

我认为可能的问题是我正在尝试使用eclipse运行我的Maven项目，但是webapp文件夹和Maven依赖项似乎没有正确部署到目标文件夹。

我通过执行以下操作创建了项目：文件＆gt;新＆gt; Maven项目＆gt;行家-原型-快速启动

以下是目录在创建时的注意事项：

src
    main
        java
            site
                site
                    App.java
    test
        java
            site
                site
                    AppTest.java
target
pom.xml

经过一些修改，更新pom.xml并运行命令

mvn eclipse:eclipse -Dwtpversion=2.0

我的项目结构如下所示：

src
    main
        java
            net
                site
                    config
                        Application.java
                        CoreConfig.java
                        MVCConfig.java
                        SecurityConfig.java
                    controller
                        IndexController.java
        resources
        webapp
            WEB-INF
                views
                    index.jsp
                    login.jsp
    test
        java
        resources
target
    m2e-wtp
        web-resources
            META-INF
                MANIFEST.MF
                maven
                    site
                        site
                            pom.properties
                            pom.xml
.classpath
.project
pom.xml

编译和运行时生成的目标目录结构如下所示：

target
    classes
        net
            site
                config
                    Application.class
                    CoreConfig.class
                    MVCConfig.class
                    SecurityConfig.class
                    WebAppInitializer.class
                controller
                    IndexController.class
    m2e-wtp
        web-resources
            META-INF
                MANIFEST.MF
                maven
                    site
                        site
                            pom.properties
                            pom.xml
    test-classes

也许我对在编译和运行应用程序时应该如何部署webapp和资源文件夹感到困惑，但根据我的Web部署程序集，应该发生以下情况：

Source                                  Deploy Path
/src/main/java/                   ->    /target/WEB-INF/classes/
/src/main/resources/              ->    /target/WEB-INF/classes/
/src/main/webapp/                 ->    /target/
/src/test/java/                   ->    /target/WEB-INF/classes/
/src/test/resources/              ->    /target/WEB-INF/classes/
/target/m2e-wtp/web-resources/    ->    /target/

至于我的构建路径，它目前看起来像这样：

site/src/main/java
    Output folder: site/target/classes
    Included: (All)
    Excluded: (None)
    Native library location: (None)
    Ignore optional compile problems: No
site/src/main/resources
    Output folder: site/target/classes
    Included: (All)
    Excluded: **
    Native library location: (None)
    Ignore optional compile problems: No
site/src/test/java
    Output folder: site/target/test-classes
    Included: (All)
    Excluded: (None)
    Native library location: (None)
    Ignore optional compile problems: No
site/src/test/resources
    Output folder: site/target/test-classes
    Included: (All)
    Excluded: **
    Native library location: (None)
    Ignore optional compile problems: No

也许构建路径和Web部署程序集彼此冲突，或者我可能只是没有以正确的方式构建它？我按下Eclipse的运行按钮运行这个应用程序，并使用Spring Boot，如下所示：

package net.site.config;

import java.util.Arrays;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application
{
    public static void main(String[] args) throws Throwable
    {
        ApplicationContext ctx = SpringApplication.run(Application.class, args);
        System.out.println("Inspecting the beans provided by Spring Boot:");

        String[] beanNames = ctx.getBeanDefinitionNames();
        Arrays.sort(beanNames);
        for(String beanName : beanNames)
        {
            System.out.println(beanName);
        }
    }
}

如果我的pom.xml可以使用：

你可以做的事情

  1. 检查<welcome-file-list>。{/ li>中的web.xml
  2. 启用DEBUG日志记录spring并检查服务器启动时是否映射IndexController控制器
