springboot搭配thymeleaf访问html页面的时候，什么时候需要自定义前缀和后缀呢
为什么我全部使用默认配置会报错，必须自己定义前缀和后缀
解析器配置如下：
@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter implements ApplicationContextAware {
//实现的这个接口能帮助我们设置spring的上下文
private ApplicationContext applicationContext;
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.applicationContext=applicationContext;
}
//对模板资源进行解析(模板资源解析器
@Bean
@ConfigurationProperties(prefix = "spring.thymeleaf")
public SpringResourceTemplateResolver templateResolver() {
SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
templateResolver.setApplicationContext(this.applicationContext);
templateResolver.setCharacterEncoding("UTF-8");
return templateResolver;
}
@Bean
public SpringTemplateEngine templateEngine(){
SpringTemplateEngine templateEngine=new SpringTemplateEngine();
templateEngine.setTemplateResolver(templateResolver());
//设置支持spring el表达式
templateEngine.setEnableSpringELCompiler(true);
return templateEngine;
}
//配置视图解析器
@Bean
public ThymeleafViewResolver viewResolver(){
ThymeleafViewResolver viewResolver=new ThymeleafViewResolver();
viewResolver.setTemplateEngine(templateEngine());
return viewResolver;
}
}thymeleaf属性只配置
控制器代码为：
启动项目后，访问http://localhost:8080/helloword就会报解析thymeleaf错误如下
这个报错真的很懵。求问为什么？
