关于SpringBoot 整合freemarker报错问题

错误信息:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'freeMarkerConfigurer' defined in class path resource [org/springframework/boot/autoconfigure/freemarker/FreeMarkerServletWebConfiguration.class]: Invocation of init method failed; nested exception is java.lang.NoSuchFieldError: DEFAULT_INCOMPATIBLE_IMPROVEMENTS

报错原因:freemarker版本问题

通常情况下将其换为2.3.23

如下所示:

 <dependency>
             <groupId>org.freemarker</groupId>
             <artifactId>freemarker</artifactId>
             <version>2.3.23</version>
  </dependency>

 

即可解决该问题
