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

Question

我认为这会非常简单，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。这是我所做的：

我在 web.xml 中添加了以下内容：

<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>

然后我创建了以下控制器（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？ :( 我在 /setting/fruit?setting_family=foods

尝试执行 GET 请求时收到 404 not found 异常

Answer 1

当您向您的调度程序声明 url 模式为“/setting/*”，然后在控制器中您将“/setting”声明为该控制器的根 requestMapping，您应该能够访问您的控制器使用这个 url: /setting/setting/fruit?setting_family=foods :)
