我在使用 spring mvc 3.2.4.RELEASE 实现一个非常简单的页面时遇到问题。

我的 Controller 看起来像这样:

@Transactional
@Controller
public class MembersDetailsController {
    @Autowired
    private MemberService memberService;

    @RequestMapping(value = "/member/{name}", method = RequestMethod.GET)
    public String displayMember(@PathVariable String name) {
        System.out.println(name);
        return "member";
    }

    @RequestMapping(value = "/member", method = RequestMethod.GET)
    public String displayMember() {
        System.out.println("Empty");
        return "member";
    }
}

当我打电话

http://127.0.0.1:8080/member

相应的方法正在按要求执行。然而，我调用

http://127.0.0.1:8080/member/test

或

http://127.0.0.1:8080/member/test/

我得到一个带有日志输出的 404:

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

真正奇怪的是之前的日志说:

INFO  org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Mapped "{[/member/{name}],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String 
INFO  org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Mapped "{[/member],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String

这意味着据我所知映射应该是正确的。

这是我的 web.xml:

谁能告诉我这里出了什么问题？

最佳答案

我认为问题与此处描述的问题相同 URL Mapping issue - Spring web MVC .

除非您使用 alwaysUseFullPath spring mvc 会将 * 部分匹配到您指定的映射(例如/member/member/test )。请在此处查看 alwaysUseFullPath 的文档(第 17.4 节)http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/mvc.html .

但是，不幸的是，此属性未通过 xml 配置元素公开(如果您使用的是 xml 配置)，因此如果您希望映射按照您在问题中描述的方式工作，则需要将其配置为此处描述:http://blog.sarathonline.com/2013/07/enable-alwaysusefullpath-with.html
