thymeleaf常见的坑

一、事件传值

Thymeleaf：如何用 th：onclick 给方法传递参数值

一、th:onclick= "|javascript:edit('${noticemodel.mid}')|"
二、th:onclick= "|edit(${noticemodel.mid})|"

二、解决script引用 ,引用型变量,解析Object内存地址解析失败

var 变量名 = [[${后台保存变量}]]

三、值为null时报错

2020-11-12 22:55:06.613 ERROR 12280 --- [p-nio-80-exec-4] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: "class path resource [templates/user/edit.html]")] with root cause

org.springframework.expression.spel.SpelEvaluationException: EL1011E: Method call: Attempted to call method getId() on null context object
	at org.springframework.expression.spel.ast.MethodReference.throwIfNotNullSafe(MethodReference.java:154) ~[spring-expression-5.2.10.RELEASE.jar:5.2.10.RELEASE]

解决方案：

加上"?"

四、thymeleaf标签中的值爆红

解决方案：
开头加上：<!--suppress ThymeleafVariablesResolveInspection -->

说明：以上均是自己踩过的坑，忘各位少走弯路。。。
