@Override
public int addDiscussPost(DiscussPost discussPost) {
    if (discussPost == null) throw new IllegalArgumentException("参数内容不得为空");

    //对特殊字符进行转义
    discussPost.setTitle(HtmlUtils.htmlEscape(discussPost.getTitle()));
    discussPost.setContent((HtmlUtils.htmlEscape(discussPost.getContent())));
    //对敏感词进行过滤
    discussPost.setTitle(sensitiveWordsFilter.filter(discussPost.getTitle()));
    discussPost.setContent(sensitiveWordsFilter.filter(discussPost.getContent()));

    return discussPostMapper.insertDiscussPost(discussPost);
}

如何对敏感词进行过滤？

public static String getJSONString(int code, String msg, Map map) {
    JSONObject json = new JSONObject();
    json.put("code", code);
    json.put("msg", msg);
    if (map != null) {
        for (String key : map.keySet()) {
            json.put("key", map.get(key));
        }
    }
    return json.toJSONString();
}

public static String getJSONString(int code, String msg) {
    return getJSONString(code, msg, null);
}

public static String getJSONString(int code) {
    return getJSONString(code, null, null);
}

@PostMapping("/add")
@ResponseBody
public String addDiscussPost(String title, String content) {
    User user = hostHolder.getUser();
    if (user == null) {
        return CommunityUtil.getJSONString(403, "您还未登录！");
    }

    DiscussPost discussPost = new DiscussPost();
    discussPost.setUserId(user.getId());
    discussPost.setTitle(title);
    discussPost.setContent(content);
    discussPost.setCreateTime(new Date());
    discussPostService.addDiscussPost(discussPost);

    return CommunityUtil.getJSONString(0,"发布成功！");
}

如何用ThreadLocal（HostHolder工具）保存用户登录数据？

$(function(){
	$("#publishBtn").click(publish);
});

function publish() {
	$("#publishModal").modal("hide");
	//获取标题和内容
	var title = $("#recipient-name").val();
	var content = $("#message-text").val();
	//发送异步请求
	$.post(
		//发送路径
		CONTEXT_PATH + "/discuss/add",
		//发送内容
		{"title":title,"content":content},
		//回调函数
		function (data) {
			data = $.parseJSON(data);
			//在提示框中显示返回信息
			$("#hintBody").text(data.msg);
			//显示提示框
			$("#hintModal").modal("show");
			setTimeout(function(){
				$("#hintModal").modal("hide");
				// 刷新页面
				if(data.code == 0) {
					window.location.reload();
				}
			}, 2000);
		}
	);
}
