Spring DispatcherServlet：找不到HTTP请求的映射

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";
    }
}

当我打电话

http://127.0.0.1:8080/member

各个方法正在按需执行。但是，我打电话给

http://127.0.0.1:8080/member/test

要么

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

我得到一个404的日志输出：

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

真正奇怪的是以前的日志说：

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

就我所知，这意味着映射应该是正确的。

这是我的web.xml：

    <welcome-file>/login</welcome-file>
  </welcome-file-list>

有人可以给我提示这里出了什么问题吗？

回答：

我相信问题与此处描述的URL映射问题-Spring WebMVC相同。除非您使用alwaysUseFullPath，否则spring mvc将*部分与您指定的映射（例如/ member /member/test）匹配。请在此处（第17.4节）中查看有关alwaysUseFullPath的文档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，如果您希望映射以问题中描述的方式工作，则需要按以下说明进行配置：http://blog.sarathonline.com/2013/07/enable-

alwaysusefullpath-with.html
