在SpringBoot项目中，使用thymeleaf模板中使用th:onclick来调用javascript方法时异常。异常信息如下：

org.thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: "class path resource [templates/index.html]")

Caused by: org.attoparser.ParseException: Only variable expressions returning numbers or booleans are allowed in this context, any other datatypes are not trusted in the context of this expression, including Strings or any other object that could be rendered as a text literal. A typical case is HTML attributes for event handlers (e.g. "onload"), in which textual data from variables should better be output to "data-*" attributes and then read from the event handler.

问题代码如下：

<button class="btn" th:onclick="'getName(\''+${person.name}+'\');'">获得名字</button>

解决方案:

<button class="btn" th:onclick="getName([[${person.name}]])">获得名字</button>
