使用 PathVariable 的 Spring RequestMapping 结果为 404

Question

我有一个 spring 应用程序，但无法解决问题。当我使用 PathVariable 时，我的 RequestMapping 中的值被添加到 URI，并且 DispatchHandler 变得困惑。

例如，当我请求/Dashboard/project/1131/

我得到 HTTP 状态 404 -/Dashboard/project/1131/WEB-INF/jsp/projectDetail.jsp

项目/1131 由于某种原因被添加到路径中

当我请求 /Dashboard/projects 时，Spring 找到我的 .jsp 并将其呈现。/project/{projectId} 不起作用 - 我遇到了上述行为。

这是我的 Controller

@Controller
public class ProjectController {

protected final Log logger = LogFactory.getLog(getClass());

@RequestMapping(value = "projects", method=RequestMethod.GET)
public String projects() {
    return "/projects";
}

@RequestMapping(value="/project/{projectId}", method=RequestMethod.GET)
public String project(@PathVariable("projectId") String projectId, ModelMap map) {
    map.put("projectId", projectId);
    logger.info("Project Id: " + projectId);
    return "/projectDetail";
}

}

我的配置

<!-- hand all requests to dispatcher service -->

    <servlet-name>dashboard</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

</web-app>

应用配置

@Configuration
public class AppConfig {

@Bean
ViewResolver viewResolver() {
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("WEB-INF/jsp/");
    resolver.setSuffix(".jsp");
    return resolver;
}

}

仪表板-servlet.xml...

<!-- Tell Spring that MVC components are @Annotation Driven -->

<bean id="messageSource"
    class="org.springframework.context.support.ResourceBundleMessageSource">

</beans>

这一定很简单 - 但我已经阅读了文档并在互联网上搜索了几个小时。从我所看到的看来，我所做的一切都是正确的。

Answer 1

我认为在 resolver.setPrefix("/WEB-INF/jsp/"); 中有一个前导斜杠应该可以为您修复它。
