我开发了一个提供 Spring MVC REST 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。

我想要达到的目标：

  • /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

我也希望 index.html 默认加载。

目前我正在使用以下配置，但默认情况下它不加载 index.html 。但我不知道这是否真的是我应该在 Spring Container 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>

应用程序上下文.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如何配置这样的设置吗？

下面你可以看到我的 debug.log。这里的问题似乎如下：

没有找到 [/] 的处理程序方法

所以我猜 DispatcherServlet 正在尝试将路径映射到控制器。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。

我遇到了同样的问题，我按照您的建议解决了，为 Spring 管理的其余 api 模式添加前缀。

唯一的区别是我没有使用 url 重写器，因为我所有的 angular 文件都部署在 web 应用程序的根目录中，因此可以直接访问。

我的 Angular 项目实际上位于不同的文件夹中，作为不同的模块，并在战争构建期间使用此配置添加：

<plugin>
     <artifactId>maven-war-plugin</artifactId>
     <version>2.3</version>
     <configuration>
         <webResources>
             <resource>
                 <directory>${project.parent.basedir}/ANGULAR-PROJECT-NAME
             </resource>
         </webResources>
     </configuration>
</plugin>

就像这里解释的那样。希望这会有所帮助，问候。

主要问题是 <mvc:resource> 注册的 ResourceHttpRequestHandler 在请求 foo/ 时没有解析为 foo/index.html

启用此行为的参数会很好。

我已经通过以下方式解决了我的问题。

  • 首先，我将路径从 servlet-mapping 更改为 /api/*。我不得不将 MVC 控制器中的路径从 @RequestMapping("/api/role") 调整为 @RequestMapping("/role")。否则 URL 会响应 /api/api/role。
  • 然后我集成了 urlrewrite http://tukey.org/urlrewrite/。我正在使用 Maven，所以我将它添加到 pom.xml 中。我这样做是因为 mvc:resource 映射指令似乎只在使用 DispatcherServlet 时才起作用。这就是我想为我的静态 html 页面禁用的内容。
  • 然后我将过滤器添加到 web.xml 文件中，并在 WEB-INF 目录中创建了一个 urlrewrite.xml 文件，如下所示。
  • 使用 urlrewrite 我可以设置一个条件，排除 /api/**（我的基于 Spring MVC 的 REST 控制器的目录），但将 /** 中的任何其他内容重写到 /resources/ang2/app 目录（我的 angularjs 目录）。
  • 我还从 applicationContext.xml 中删除了 mvc:resource 指令。

web.xml

<!-- Setup urlrewrite filter -->
<filter>
    <filter-name>UrlRewriteFilter</filter-name>
    <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
    <init-param>
        <param-name>logLevel</param-name>
        <param-value>WARN</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>UrlRewriteFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<!-- Spring related section -->
<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>/api/*</url-pattern>
</servlet-mapping>

urlrewrite.xml

<!-- Use urlrewritefilter to redirect / requests to angularjs directory -->
<urlrewrite default-match-type="wildcard">
<rule>
    <!-- exclude everything in /api/** directory -->
    <condition type="request-uri" operator="notequal">/api/**</condition>
    <!-- everything else from / is redirected to the angularjs directory -->
    <from>/**</from>
    <to>/resources/ang2/app/$1</to>
</rule>
</urlrewrite>
