Spring DispatcherServlet: No mapping found for HTTP request
提问by Randy
I have an issue implementing a very simple page using spring mvc 3.2.4.RELEASE.
我在使用 spring mvc 3.2.4.RELEASE 实现一个非常简单的页面时遇到了问题。
My controller looks like this:
我的控制器看起来像这样：
@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";
}
}
When I call
当我打电话
http://127.0.0.1:8080/member
the respective method is being executed as desired. However, wenn I call
正在根据需要执行相应的方法。然而，我叫
http://127.0.0.1:8080/member/test
or
或者
http://127.0.0.1:8080/member/test/
I get a 404 with the log-output:
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'
Whats really weired is the a previous log says:
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
Which means that the mapping should be correct as far as I understand this.
这意味着就我的理解而言，映射应该是正确的。

Could anybody please give me a hint what went wrong here?
有人可以给我一个提示这里出了什么问题吗？

I believe that the problem is the same one as described here URL Mapping issue - Spring web MVC.
我相信问题与此处描述的URL 映射问题 - Spring web MVC 相同。
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.
除非您使用 alwaysUseFullPath spring mvc 将匹配 * 部分到您指定的映射（例如 /member/member/test ）。请参阅此处的 alwaysUseFullPath 文档（第 17.4 节）http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/mvc.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
但是，不幸的是，此属性不会通过 xml 配置元素公开（如果您使用 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，则需要按照此处所述进行配置：http://blog.sarathonline.com/2013/07/enable-alwaysusefullpath-with.html

I was faced with the same problem and solved problem by using
我遇到了同样的问题并通过使用解决了问题
<mvc:annotation-driven/>
This tag will configure two beans DefaultAnnotationHandlerMapping and AnnotationMethodHandlerAdapter.
这个标签会配置两个 bean DefaultAnnotationHandlerMapping 和 AnnotationMethodHandlerAdapter。
Also I added tag to my dispatcher servlet config file.
我还向调度程序 servlet 配置文件中添加了标记。
<context:component-scan base-package="PATH WHERE FIND CONTROLLERS" />
