java - 两个 servlet 中的 Spring、MVC 和 REST

转载作者：行者123 更新时间：2023-11-30 10:55:47

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。就像它不存在一样，或者请求以某种方式不匹配。

更多详情:

我的spring版本是4.2.1。

我有一个使用 Spring MVC 的应用程序，它已经可以运行了。问题是第二个 servlet，我想添加它，以便它处理 REST 请求。

这是 web.xml 之前我尝试将 REST servlet 添加到其中(因此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 - 所有请求 *.do将由 MVC servlet 处理，一般所有请求都将通过 Spring Security。

我有一个简单的 MVC Controller 来处理:

@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;
    }
}

Controller 位于通过 servlet 上下文 xml 文件中的适当扫描声明扫描的包中。

现在，我为启用 REST 所做的是将以下 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 ，我把 <context:component-scan base-package="my.app.rest"/> 放在哪里- 这就是包，然后我将 RestController 放在那里，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";
    }
}

rest Controller 确实已创建(我调试了构造函数)，因此 spring 确实看到了它，但是当我尝试从 Postman(Chrome 扩展)调用它时，我收到 404 响应。我的请求是 URL:localhost:8080/acc/user.rest (其中 acc 是我的应用名称)。

为什么我的电话匹配*.rest没有被重定向到正确的 Controller ？ (我试图在调试中停在那里 - 它从未被调用过)。

这是我当前的完整 web.xml:

我有 @Controller用于 my.app.web 中的 MVC我有 @RestController在 my.app.rest .
