@RequestMapping("/admin") public String index(ModelMap modelMap,HttpServletRequest req){ String scheme = req.getScheme(); String serverName = req.getServerName(); int serverPort = req.getServerPort(); String path = req.getContextPath(); String basePath = scheme+"://"+serverName+":"+serverPort+path+"/"; modelMap.put("basePath",basePath); modelMap.put("adminPath", basePath+"admin/"); modelMap.put("staticPath", basePath+"static/admin/common"); return "admin/index"; } @RequestMapping("/admin/login") public String login(ModelMap modelMap,HttpServletRequest req){ String scheme = req.getScheme(); String serverName = req.getServerName(); int serverPort = req.getServerPort(); String path = req.getContextPath(); String basePath = scheme+"://"+serverName+":"+serverPort+path+"/"; modelMap.put("basePath",basePath); modelMap.put("adminPath", basePath+"admin/"); modelMap.put("staticPath", basePath+"static/admin/common"); return "admin/login"; } 獲取路徑的代碼寫了兩份 ,感覺好臃腫啊,怎么讓只寫一份,然后給共用?

1.首先中間件概念你沒弄清楚，不能亂用
2.回到你的問題，就是一個(gè)方法抽取的場(chǎng)景，建議看一下<<代碼重構(gòu)>>這本書

代碼隨便重構(gòu)一下就好看多了

public String index(ModelMap modelMap,HttpServletRequest req){
    String basePath = getBasePath(req);
    modelMap.put("basePath",basePath);
    modelMap.put("adminPath", basePath+"admin/");
    modelMap.put("staticPath", basePath+"static/admin/common");
    return "admin/index";
}
private String getBasePath(HttpServletRequest req) {
    String scheme = req.getScheme();
    String serverName = req.getServerName();
    int serverPort = req.getServerPort();
    String path = req.getContextPath();
    String basePath = scheme+"://"+serverName+":"+serverPort+path+"/";
    return basePath;
}
