关于application.properties安全性的问题

问题：如果把application.properties也上传到Github仓库，那不是把数据库用户名密码和client_secret公开了吗？请问对于这个问题有没有什么比较通用的解决方法呢？

Flyway upgrade recommended: H2 1.4.199 is newer than this version of Flyway and support has not been tested.

我看到Flyway upgrade recommended: H2 1.4.199 is newer than this version of Flyway and support has not been tested.
我需要做些什么呢?

production.properties如何写

用词错误

要部署服务器吗，我这爆500了

前端的一个小bug

提问页面，添加标签时，若添加了"docker"就无法再添加"c", 因为字符串"c"在"docker"中出现过。
即添加一个标签时，如果这个标签之前并不存在，但是只要有一个包含了这个标签字符串的另一个标签存在，就无法添加这个标签。
community.js中的selectTag方法，

function selectTag(e) {
    var value = e.getAttribute("data-tag");
    var previous = $("#tag").val();
    if (previous.indexOf(value) == -1) {
        if (previous) {
            $("#tag").val(previous + ',' + value);
        } else {
            $("#tag").val(value);
        }
    }
}

目前只判断了待添加标签字符串value是否在previous中出现过，
可以改为:
找到previous中出现的所有value子串, 并判断每个value子串是一个独立标签还是另一个标签的一部分。若都只是另一个标签的一部分，那么这个新标签是可以添加的

搜索时，输入? 会有异常

TLS certificate of the live demo has expired

人家这个项目B站的视频播放量十几万，这群人有病吧，沃日。

评论这些人你们知道github是用来干啥的吗，你们居然一个仓库都没有，真搞笑

请问怎么解决？

搜索的内容有空格的时候,如何处理URL中的"+"

Cannot resolve method 'create' in 'RequestBody'

RequestBody body = RequestBody.create(mediaType, JSON.toJSONString(accessTokenDTO));
Request request = new Request.Builder()
.url("https://github.com/login/oauth/access_token")
.post((okhttp3.RequestBody) body)
.build();

create方法报错，如何解决啊？卡在这里了

目前项目是否是完整的

你好，今天我下载了项目，发现很多地方都是有错误的比如：AccessTokenDTO中字段并没有get和set方法，而在AuthorizeController.java中callback方法中却调用了AccessTokenDTO类的set方法

h2数据库新建comment表后报错

[WARNING] Table configuration with catalog null, schema null, and table comment did not resolve to any tables

跑起来的效果

开源不易，辛苦了

https证书

如何添加https证书呢?另外我想把这个社区名字改一下这个如何改动呢?

Gitee第三方授权登陆，回调函数出错。

出现提示：登录存在错误，无效的登录回调地址。怎么解决的，麻烦问一下【回调函数没问题】

发现NPE风险

您好，我正在用蚂蚁的单元测试用例自动生成工具（https://github.com/TRaaSStack/auto-unit-test-case-generator）
对这个项目进行测试，发现如下两个可能引发NPE的问题，期待得到您的反馈。
一 HotTagCache类中可能抛出NPE
被测方法的入参为Map，在其中一个添加的元素的value赋null值

被测方法：

源码中在遍历元素的时候，由于其中的一个元素的value值为空，而代码中未对null做非空校验，导致在进入compareTo的时候，this.getPriority()获取的值为null，从而报npe异常

二 UserStrategyFactory类中可能抛出NPE
调用被测方法之前，先对被测类的私有属性类型为list的strategies赋初值，即在list中添加null元素

被测方法：

在被测方法中，遍历list时，未对元素strategy做非空判断，导致strategy.getSupportedType()操作时报npe

zx

下载的代码打不开

通过 github 账户登录无法发表问题

经过调试发现在 src/main/java/life/majiang/community/controller/PublishController.java 的 user.getDisable() 中没有判断为 null 。

mvn flyway:migrate时报这个错误是什么原因啊？

mvn flyway:migrate 执行报错

看readme文档
3. 运行数据库脚本，创建本地数据库

mvn flyway:migrate

如果需要使用 MySQL 数据库，运行脚本前修改两处配置

# src/main/resources/application.properties 
spring.datasource.url=jdbc:h2:~/community
spring.datasource.username=sa
spring.datasource.password=123

# pom.xml
<properties>
    <db.url>jdbc:h2:~/community</db.url>
    <db.user>sa</db.user>
    <db.password>123</db.password>
</properties>

然后我改成了，

src/main/resources/application.properties

spring.datasource.url=jdbc:mysql://localhost:3306/community?useUnicode=true&characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

pom.xml

jdbc:mysql://localhost:3306/community?useUnicode=true&characterEncoding=utf8 root 123456 ```

执行

mvn flyway:migrate

报错：
