String spelExpr = nacosValueExpr.replaceAll("\\$\\{" + key + PLACEHOLDER_SUFFIX, newValue);

如果配置的value中包含$符号,String.replaceAll()会抛出异常,导致配置无法更新

正常情况下,配置内容包含$也是为了引用配置中的另一个值吧?还有配置内容本身就抱哈$的吗

这种情况可以把配置内容中的$换成 \$

感谢答复,我试配置内容本身就包含$,我试了一下换成\$ 符可以读取到$, 但是在使用@NacossValue刷新配置的时候会报错,刷新时使用\\$才不会报错,可以看一下这个链接 @hujun-w-2

我想说的就是换成 \\$ ,直接评论自动变成\$

启动应用读取配置,和使用@NacosValue刷新配置,读取规则不一样,导致使用\\$配置时,启动应用读取到\$,而刷新配置读取到$,二者不一致,具体可以看看上面的链接。
