逆水行舟

HttpServletRequest中方法getRequestURI和getRequestURI等的区别

项目在tomcat中的目录结构是这样子的: webapps/testApp/项目内容
webapps为tomcat容器的目录
testApp即为项目部署的名称
项目的代码片段是这样子的:

@RestController
@RequestMapping("/testController")
public class TestController {
    @RequestMapping("/testAPI.htm")
    public ModelAndView test(HttpServletRequest request, HttpServletResponse response) {
        Map<String, Object> map = Maps.newHashMap();
        map.put("getContextPath", request.getContextPath());
        map.put("getServletPath", request.getServletPath());
        map.put("getRequestURL", request.getRequestURL());
        map.put("getRequestURI", request.getRequestURI());
        map.put("getQueryString", request.getQueryString());
        return new ModelAndView(new MappingJackson2JsonView(), map);
    }
}

请求的URL为: http://localhost:8080/testApp/testController/testAPI.htm?a=1&b=2
得到的结果是:

{
    "getContextPath":"/testApp",
    "getServletPath":"/testController/testAPI.htm",
    "getRequestURL":"http://localhost:8080/testApp/testController/testAPI.htm",
    "getRequestURI":"/testApp/testController/testAPI.htm",
    "getQueryString":"a=1&b=2"
}

变量名称	变量值
ContextPath	项目部署路径，没有名称(如直接部署在在ROOT里)则为空串
ServletPath	请求地址(不包括项目名称)
RequestURL	整个URL(不包括查询参数)
RequestURI	请求地址(包括项目名称)
QueryString	?后面的那一堆查询串
