java - 如何将 servlet 添加到 spring 框架 java web 应用程序？

Question

我认为这非常简单，但显然我遗漏了一些东西，而且我似乎无法弄清楚它是什么。

我正在尝试将 servlet 添加到使用 java 和 spring 编写的现有 Web 应用程序中。这是我所做的:

我将以下内容添加到 web.xml:

<servlet>
    <servlet-name>SettingServlet</servlet-name>
    <display-name>SettingServlet</display-name>
    <description>Provides a rest endpoint for getting and setting settings.</description>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/SettingServlet-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>SettingServlet</servlet-name>
  <url-pattern>/setting/*</url-pattern>
</servlet-mapping>

然后我创建了以下文件(.../WEB-INF/SettingServlet-servlet.xml):

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:p="http://www.springframework.org/schema/p"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd"
>

<bean id="settingController"
  class="com.my.package.path.SettingController"
  p:settingService-ref="settingService"/>

</beans>

然后我创建了以下 Controller (com.my.package.path.SettingController.java):

@Controller
@RequestMapping("/setting")
public class SettingController {
    private SettingService settingService;
    public void setSettingService(final SettingService settingService) {
        Validate.notNull(settingService, "SettingController::settingService cannot be null");
        this.settingService = settingService;
    }

    @ResponseBody
    @RequestMapping(value = "/{name}", method = RequestMethod.GET)
    @Secured({ "ROLE_ADMINISTRATOR", "ROLE_CURIOUS_GEORGE" })
    public ResponseEntity<String> getSettingRequest(@PathVariable("name") final String name, @RequestParam("setting_family") final String settingFamily) {
        final String jsonBody = "{\"setting\":\"" + name + "\", \"Setting Family\":\"" + settingFamily + "\", \"value\":\"test\"}";
        return new ResponseEntity<String>(jsonBody, HttpStatus.OK);
    }
}

我做错了什么？ :( 尝试在/setting/fruit?setting_family=foods 执行 GET 请求时收到 404 未找到异常

当您将调度程序的 url 模式声明为“/setting/*”，然后在 Controller 中声明“/setting”作为该 Controller 的根 requestMapping 时，您应该能够使用以下 url 访问您的 Controller :/setting/setting/fruit?setting_family=食物:)
