我试图配置DispatcherServlet中的URL以映射到没有扩展名的URL。我终于明白了这一点,但我不明白为什么URL正在按照这种方式工作。了解使用DispatcherServlet使用alwaysUseFullPath属性的URL映射
假设'foobar'的上下文...如果DispatcherServlet的url模式是/ rest/*并且我有一个/ rest/js的RequestMapping,那么为了进入页面,我必须转到主机名:port/foobar/rest/rest/js。为什么网址有双重/休息/休息?
这没有任何意义,因为如果我有多个DispatcherServlets,不能将相同的RequestMapping转到不同的URL吗?即如果RequestMapping是'/ js',并且我有一个DispatcherServlet设置为/ rest/*,另一个设置为/ json/*,那么hostname:port/foobar/rest/js和hostname:port/foobar/json/js返回相同的页面?
如果@RequestMapping位于类定义上,我无法得到URL,它只能在方法上使用。

JServicesController.java:
@Controller
public class JServicesController {
@Autowired
private TheService theService;
@ResponseBody
@RequestMapping("/rest/js")
public TheContent getTheContent() {
return theService.getTheContent();
}
}
任何想法为什么当我将@RequestMapping放在类型定义上时,我无法完成这项工作?它只适用于该方法,而不像我见过的众多示例。 – acvcu 2012-02-03 17:26:42
粘贴相关代码 – soulcheck 2012-02-03 17:47:00
这是我已发布的相同代码,除非您将@RequestMapping(“/ rest/js”)移至课程级别。 – acvcu 2012-02-03 17:57:13
