1.HttpServletRequest

@GetMapping("/getParameter")
String getString(HttpServletRequest request) {
    //获取一个参数
    String name=request.getParameter("appId");
    //获取所有参数
    Map map=request.getParameterMap();
    return name;
}

2.@RequestHeader

@GetMapping("/getParameter")
public String test(@RequestHeader("appId") String appId) {
    return appId;
}

3.RequestContextHolder的使用

/两个方法在没有使用JSF的项目中是没有区别的
RequestAttributes requestAttributes = RequestContextHolder.currentRequestAttributes();
//RequestContextHolder.getRequestAttributes();
HttpServletRequest request = ((ServletRequestAttributes)requestAttributes).getRequest();
HttpServletResponse response = ((ServletRequestAttributes)requestAttributes).getResponse();
String appId = request.getHeader("appId");


//从session里面获取对应的值
String str = (String) requestAttributes.getAttribute("name",RequestAttributes.SCOPE_SESSION);
