Spring DispatcherServlet：找不到HTTP请求的映射 [英] Spring DispatcherServlet: No mapping found for HTTP request

问题描述

我在使用spring mvc 3.2.4.RELEASE实现一个非常简单的页面时出现问题。

I have an issue implementing a very simple page using spring mvc 3.2.4.RELEASE.

我的控制器如下所示：

@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";
    }
}

当我致电

http://127.0.0.1:8080/member

正在根据需要执行相应的方法。但是，我打电话给

the respective method is being executed as desired. However, wenn I call

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：

I get a 404 with the log-output:

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

真正需要的是以前的日志说：

Whats really weired is the a previous log says:

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

这意味着根据我的理解，映射应该是正确的。

Which means that the mapping should be correct as far as I understand this.

这是我的web.xml：

有人可以告诉我这里出了什么问题吗？

Could anybody please give me a hint what went wrong here?

推荐答案

我认为问题与此处描述的问题相同 URL映射问题 - Spring Web MVC 。

I believe that the problem is the same one as described here URL Mapping issue - Spring web MVC .

除非你使用alwaysUseFullPath，否则mvc会将* part与你指定的映射匹配（例如/ member / member / test）。请参阅alwaysUseFullPath的文档（第17.4节） http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/mvc.html 。

Unless you use alwaysUseFullPath spring mvc will match * part to the mapping you specified (e.g. /member/member/test ). See docs for alwaysUseFullPath here (section 17.4) http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/mvc.html .

但是，遗憾的是，此属性不是通过xml配置元素公开的（如果您使用的是xml配置），那么如果您希望映射按照您在问题中描述的方式工作，则需要按照此处所述进行配置： http://blog.sarathonline.com/2013/07/enable- alwaysusefullpath-with.html

However, unfortunately, this property is not exposed through xml configuration element (if you're using xml configuration) so if you'd like your mappings to work the way you discribed in your question you'll need to configure it as described here: http://blog.sarathonline.com/2013/07/enable-alwaysusefullpath-with.html
