为什么模板“Spring MVC 项目"在“SpringSource工具套件"中不适用于Tomcat? [英] Why Template "Spring MVC Project" in "SpringSource Tool Suite" not work with Tomcat?

问题描述

当我在 SpringSource 工具中创建 Spring MVC 模板项目并尝试在 Tomcat 服务器上运行时出现此错误:

When Im create Spring MVC Template project in SpringSource Tool and try to Run on the Tomcat server I have this error:

WARN : org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/test/] in DispatcherServlet with name 'appServlet'.

这是默认的:/test/src/main/java/ru/test/test/HomeController.java

This is default: /test/src/main/java/ru/test/test/HomeController.java

@Controller
public class HomeController {

    private static final Logger logger = LoggerFactory
            .getLogger(HomeController.class);

    /**
     * Simply selects the home view to render by returning its name.
     */
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String home(Locale locale, Model model) {
        logger.info("Welcome home! the client locale is " + locale.toString());

        Date date = new Date();
        DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG,
                DateFormat.LONG, locale);

        String formattedDate = dateFormat.format(date);

        model.addAttribute("serverTime", formattedDate);

        return "home";
    }

}

默认/test/src/main/webapp/WEB-INF/spring/root-context.xml 为空

Default /test/src/main/webapp/WEB-INF/spring/root-context.xml is empty

推荐答案

我遇到了完全相同的问题，我解决了.基本上，在创建 Spring MVC 项目时，Eclipse 默认不会将 src/main/webapp 配置为源目录.它可能需要是一个源目录，因为这样 Eclipse 在构建它时会以不同的方式对待这些文件.

I was getting the exact same issue and I solved it. Basically, when the Spring MVC Project gets created, Eclipse does not configure src/main/webapp as a source directory by default. It likely needs to be a source directory because then Eclipse will treat the files differently when it builds it.

右键单击webapp"文件夹并单击构建路径 -> 用作源文件夹"为我解决了这个问题.这里的其他评论是错误的:我不必更改我的 RequestMapping 或 servlet url-pattern.'/' 两者都适用于我的 'localhost:8080/test/'.

Right clicking on the 'webapp' folder and clicking 'Build Path -> Use as Source Folder' solved this issue for me. The other comments here are wrong: I did NOT have to change my RequestMapping or servlet url-pattern. '/' for both worked for my 'localhost:8080/test/'.
