Set CSS variables from model object in Thymeleaf

阅读更多关于 Set CSS variables from model object in Thymeleaf

问题 I'm setting CSS color variables inside a style tag in a Thymeleaf template. The color values are coming from the model object. I also want to apply a default color, in case the model attirbute is not there. But when I render the template, Thymeleaf doesn't evaluate the expression, but assigns the entire expression as a string literal, instead of the color value. Below is my style tag. I've done the same thing in Apache Freemarker, and it worked fine. I'm pretty new to Thymeleaf, what should I

JAR冲突问题的解决

阅读更多关于 JAR冲突问题的解决

今天碰到群里小伙伴问，线上程序好像有多个不同版本的Netty包，怎么去看到底加载了哪一个? 在说如何看之前，先来说说，当你开始意识到项目里有多个不同版本的Jar包，都是因为遇到了这几个异常： 1、java.lang.NoSuchMethodException：自己代码中调用了某个方法，因为加载了其他版本的jar，这个版本正好没这个方法。 2、java.lang.NoClassDefFoundError：编译时候是好的，但是运行的时候，因为加载的jar版本问题，没有这个类。 3、java.lang.ClassNotFoundException：在动态加载某个Class的时候，因为要加载的jar不是正确的版本，而导致找不到这个类。当你在本地运行ok，但到服务器上发现出现这些错误的时候，就要意识到很可能是jar冲突了(有相同依赖存在多个版本)。这个问题往往也会有这样的表现：多实例部署的时候，有的实例是好的，有的实例则不行。查看加载的类和方法根据之前分析的异常种类，我们可以去运行中的现场确认当前加载的问题。这里我们可以使用阿里开源的Arthas工具，如果第一次用，那么按下面操作先安装再运行： curl -O https://arthas.aliyun.com/arthas-boot.jar java -jar arthas-boot.jar 运行好之后
