弹簧启动的百万美元自动配置问题试图解决休息应用程序的错误模板

标签： spring spring-boot thymeleaf

我的Spring Boot REST应用程序仅将Thymeleaf用于邮件模板。

不幸的是，当遇到错误时，我的启动配置会尝试解析错误模板。

见下面的例外情况：

这似乎表明Spring Boot已经为页面配置了Thymeleaf视图解析器（而我只使用Thymeleaf作为邮件模板）。

如何确保Spring Boot仅将Thymeleaf用于邮件模板，从而避免上述异常？

修改：我的application.properties

有以下一行 
server.error.whitelabel.enabled=false

但它似乎没有任何区别。

2 个答案:

答案 0 :(得分：2)

在application.properties中使用此属性：

spring.thymeleaf.enabled=false

似乎禁用了春天mvc的百日咳 - 同时仍然保留了百万美元的邮件模板。

请参阅spring boot源代码here。

修改：

此外，似乎需要禁用Spring Boot注册的默认错误控制器：请参阅here。

例如，可以实现如下所述的自定义错误控制器：https://stackoverflow.com/a/25362790/536299

答案 1 :(得分：0)

@SpringBootApplication(
        exclude = {
                ThymeleafAutoConfiguration.class,
        })
public class ApiApplication {
    public static void main(String[] args) {
        SpringApplication.run(ApiApplication.class, args);
    }
}
