thymeleaf springboot-thymeleaf动态模板生成

thymeleaf动态模板：

import org.thymeleaf.context.Context;
import org.thymeleaf.spring5.SpringTemplateEngine;
import org.thymeleaf.templatemode.TemplateMode;
import org.thymeleaf.templateresolver.StringTemplateResolver;


Map data = new HashMap();
data.put("code", "1234");
SpringTemplateEngine springTemplateEngine = new SpringTemplateEngine();
//IDialect iDialect = new SpringStandardDialect();
//springTemplateEngine.setDialect(iDialect);
StringTemplateResolver stringTemplateResolver = new StringTemplateResolver();
stringTemplateResolver.setCacheable(true);
stringTemplateResolver.setTemplateMode(TemplateMode.HTML);
springTemplateEngine.setTemplateResolver(stringTemplateResolver);
Context context = new Context();
context.setVariables(data);
String content = "短信验证码为：<span th:utext=\"${code}\"></span>，5分钟内有效";
String result = springTemplateEngine.process(content, context);

pom文件引入：

<dependency>
  <groupId>org.thymeleaf</groupId>
  <artifactId>thymeleaf</artifactId>
  <version>3.0.9.RELEASE</version>
</dependency>

若直接引入：

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-thymeleaf</artifactId>
  <version>2.0.4.RELEASE</version>
</dependency>

那么如果spring-boot的版本是2.0以下的会有问题
