一、get类方法
通过实际输出验证方法：
请求路径http://10.20.20.184:8080/firstssm/test
请求主机地址：10.20.20.169
前端代码：
<body> <h1>Hello</h1> <form action="test" method="post"> <input name="test" value="测试"> <input id="sayHello" type="submit" value="say Hello"> </form> </body>
后台代码：
@RequestMapping("test")
@ResponseBody
public String test(HttpServletRequest request) {
JSONObject json = new JSONObject();
json.put("remoteHost", request.getRemoteHost());
json.put("remoteAddr", request.getRemoteAddr());
json.put("remotePort", request.getRemotePort());
json.put("remoteUser", request.getRemoteUser());
json.put("localPort", request.getLocalPort());
json.put("localAddr", request.getLocalAddr());
json.put("localName", request.getLocalName());
json.put("requestURL", request.getRequestURL());
json.put("contentLength", request.getContentLength());
json.put("contextPath", request.getContextPath());
json.put("servletPath", request.getServletPath());
json.put("realPath", request.getRealPath("test"));
json.put("CharacterEncoding",request.getCharacterEncoding());
json.put("serverPort", request.getServerPort());
json.put("authType", request.getAuthType());
json.put("contentType", request.getContentType());
json.put("pathInfo", request.getPathInfo());
json.put("pathTranslated", request.getPathTranslated());
json.put("protocol", request.getProtocol());
json.put("queryString", request.getQueryString());
json.put("scheme", request.getScheme());
json.put("serverName", request.getServerName());
logger.info(json.toString());
return json.toString();
}
输出结果：
