我有一个基本的SpringBoot应用程序。使用Spring Initializer,嵌入式Tomcat,Thymeleaf模板引擎和包作为可执行的JAR文件 在其中一个模板中,我想要连接2个值
<td class="col_name" th:text="${user.firstName} ${user.lastName}"></td><!-- NAME -->
但我得到了这个例外
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.thymeleaf.exceptions.TemplateProcessingException: Could not parse as expression: "${user.firstName} ${user.lastName}" (/noentenimnicinc/user/userList:83)

答案 0 :(得分:4)
包含加号以解决异常:
<td class="col_name" th:text="${user.firstName} + ${user.lastName}"></td>
或者您可能希望添加一个易读性空间:
<td class="col_name" th:text="${user.firstName} + ' ' + ${user.lastName}"></td>
