java - 使用 Spring 提供静态页面和 REST 服务

Question

我开发了一个为 Spring MVC REST 服务提供服务的 Spring 应用程序。现在我想在我的 Spring 应用程序的 webapp 目录中实现 Angularjs。问题是我不知道如何正确配置它。

我想要实现的目标:

• /api/... = 通过 Spring MVC 提供 REST 服务的 URL，例如 localhost:8080/api/user/1
• /... = 包含静态 html 页面的 URL，例如 localhost:8080/index.html

我还希望默认加载 index.html。

目前我正在使用以下配置，但默认情况下它不会加载 index.html。但是我不知道这是否真的是我应该在 Spring 容器中配置静态页面的方式:

web.xml

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>dispatchOptionsRequest</param-name>
        <param-value>true</param-value>
    </init-param>
</servlet>

<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

applicationContext.xml

<context:property-placeholder properties-ref="deployProperties" />

<!-- Activates various annotations to be detected in bean classes -->
<context:annotation-config />

<!-- Scans the classpath for annotated components that will be auto-registered as Spring beans.
For example @Controller and @Service. Make sure to set the correct base-package -->
<context:component-scan base-package="com.eerra" />

<!-- Configures the annotation-driven Spring MVC Controller programming model.
Note that, with Spring 3.0, this tag works in Servlet MVC only! -->
<mvc:annotation-driven/>

<!-- Tell Spring what to treat as resources -->
<mvc:resources mapping="/" location="/resources/ang2/app/"/>

使用当前配置，一切正常，但是当我尝试将浏览器指向 localhost:8080/时，会出现 404 not found 而不是加载 index.html 文件。当我尝试使用 localhost:8080/index.html 时，一切正常。

有人可以指出正确的方向来配置这样的设置吗？

在下面你可以看到我的 debug.log。这里的问题似乎如下:

没有找到 [/] 的处理方法

所以我猜想 DispatcherServlet 正在尝试将路径映射到 Controller 。但我不知道如何避免这种情况。

您是否在 web.xml 中定义了欢迎文件？

例如

<welcome-file-list>
    <welcome-file>index.html</welcome-file>
</welcome-file-list>

其中 index.html 是项目根文件夹中的一个文件。
