两个 servlet 中的 Spring、MVC 和 REST
Posted
技术标签:
【中文标题】两个 servlet 中的 Spring、MVC 和 REST【英文标题】：Spring, MVC and REST in two servlets 【发布时间】：2016-01-18 07:08:02 【问题描述】：长话短说： 我有正确处理请求的 MVC servlet，但 REST servlet 似乎根本不处理任何请求。好像它不存在，或者请求不匹配。
更多详情：
我的spring版本是4.2.1。
我有一个带有 Spring MVC 的应用程序，它已经可以工作了。问题是我要添加的第二个 servlet，因此它可以处理 REST 请求。
这是web.xml 之前我尝试将 REST servlet 添加到其中（所以到目前为止一切正常）：
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1">
<display-name>My app</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/core-context.xml /WEB-INF/spring-security.xml</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<servlet-mapping>
<servlet-name>AccServlet</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.do</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>RestServlet</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<session-config>
<session-timeout>10</session-timeout>
</session-config>
</web-app>
简而言之 - 所有对*.do 的请求都将由 MVC servlet 处理，所有请求通常都会通过 Spring Security。
我有一个简单的 MVC 控制器来处理它：
@Controller
public class JspController
@Autowired
private UserService userService;
@RequestMapping(value = "/index.do", method = RequestMethod.GET)
public String provideIndexModel(ModelMap model)
User user = userService.getLoggedUser();
model.addAttribute("user", user.getUsername());
if (user.getBusiness() != null)
model.addAttribute("business", user.getBusiness().getCompanyName());
return "index";
@RequestMapping(value = "/login.do", method = RequestMethod.GET)
public String provideLoginModel(ModelMap model)
return "login";
public UserService getUserService()
return userService;
public void setUserService(UserService userService)
this.userService = userService;
控制器位于通过 servlet 的上下文 xml 文件中的正确扫描声明扫描的包中。
现在，我启用 REST 的方法是将以下 servlet 添加到 web.xml：
<servlet>
<servlet-name>AccServlet</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>RestServlet</servlet-name>
<url-pattern>*.rest</url-pattern>
</servlet-mapping>
然后我创建了另一个 servlet 上下文文件 RestServlet-servlet.xml，我在其中放置了 <context:component-scan base-package="my.app.rest"/> - 这就是包，然后我在其中放置了一个 RestController，如下所示：
@RestController
public class RestService
public RestService()
System.out.println("yes!");
@RequestMapping(value = "/user.rest", method = RequestMethod.GET)
public String getUser()
return "abc";
确实创建了其余控制器（我调试了构造函数），所以 spring 确实看到了它，但是当我尝试从 Postman（Chrome 扩展）调用它时，我得到 404 响应。我的请求是 URL：localhost:8080/acc/user.rest（acc 是我的应用名称）。
为什么我的匹配 *.rest 的呼叫没有被重定向到正确的控制器？ （我试图在调试中停止 - 它从未被调用）。

我在my.app.web 中有用于MVC 的@Controller，在my.app.rest 中有@RestController。

请注意，日志中的最后一行来自我的 GET 请求尝试到其余服务。
【问题讨论】：
您的 web.xml 是针对 Servlet 2.3 的，因此即使您的目标容器是较新版本，很多东西也很有可能以回退兼容性方式运行。去掉 doctype 并升级<web-app> 声明以匹配目标容器支持的最新版本（Tomcat 6 = Servlet 2.5，Tomcat 7 = Servlet 3.0，Tomcat 8 = Servlet 3.1）然后重试。
好点。我已经修复它（到 3.1 版），但核心问题仍然存在。
当我升级到 servlet 3.1 时，一个有趣的事情开始出现在 tomcat 日志中。现在它在启动时打印：Mapped URL path [/acc/rest/user] onto handler 'restService'，但后来当我调用我在日志中看到的其余路径时：org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/acc/rest/user] in DispatcherServlet with name 'RestServlet'。我玩过几个映射（前面包含/acc，没有它等等 - 不幸的是没有任何效果）。
在映射中尝试 /*.rest/*。
我相信您应该在您的应用上下文 xml 中包含 <mvc:annotation-driven>，但似乎您可能错过了它。
【参考方案1】：
发现问题。事实证明，两个 *-servlet.xml 上下文文件都应该有 <mvc:annotation-driven /> 声明，以便控制器正常工作。没有它，servlet 可以工作，但映射没有正确处理。
【讨论】：
【参考方案2】：在我看来，servlet 定义和映射（<servlet-name>RestServlet</servlet-name> 和 <servlet-name>AccServlet</servlet-name>）中 servlet 名称的差异导致了问题。
您将调度程序 servlet 命名为 AccServlet 并且为 RestServlet 提供映射将不起作用。
在 spring-mvc 中，所有委托都由 DispatcherServlet 完成。可能的组合是：
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/core-context.xml /WEB-INF/spring-security.xml</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<servlet>
<servlet-name>AccServlet</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>AccServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<session-config>
<session-timeout>10</session-timeout>
</session-config>
那么你的 REST 控制器可能是这样的：
@RestController
@RequestMapping("/rest")
public class RestService
你所有的其他客户都会使用http://ip:port/yourapp/rest/something模式的URL
MVC 控制器可以是：
@Controller
@RequestMapping("/mvc")
public class JspController
@RequestMapping(value = "/index.do", method = RequestMethod.GET)
public String provideIndexModel(ModelMap model)
User user = userService.getLoggedUser();
model.addAttribute("user", user.getUsername());
if (user.getBusiness() != null)
model.addAttribute("business", user.getBusiness().getCompanyName());
return "index";
对 MVC 内容使用模式 localhost:8080/acc/mvc/index.do 的 URL。
【讨论】：
我已经尝试过了，但现在它们都不起作用。既不是mvc，也不是rest。两者都返回 404。我尝试打开http://ip:port/yourapp/mvc/、http://ip:port/yourapp/ 和 http://ip:port/yourapp/mvc/index.do - 没有成功。
而且我没有为单个 servlet 做 2 个映射 - 请注意我声明了 2 个 servlet，它们为每个 servlet 定义了一个映射。
我看不到这 2 个 servlet。你能分享统一的 web.xml 吗？此外，我更新了应该与我建议的配置一起使用的 URL。您使用的是 REST 客户端/工具吗？
另外，你能用日志语句更新你的问题吗？
我已经添加了您要求的所有信息（连同上下文文件）。关于两个 servlet - 我有两个定义为“AccServlet”和“RestServlet”的 servlet - 每个在 <servlet> 中都有自己的声明，在 <servlet-mapping> 中定义了自己的映射。以上是关于两个 servlet 中的 Spring、MVC 和 REST的主要内容，如果未能解决你的问题，请参考以下文章
