spring.framework 版本从4.1.6.RELEASE升到5.0.20.RELEASE

将org.springframework 使用到的jar 版本号改为5.0.20.RELEASE后运行会报错：

Servlet.service() for servlet [springmvc] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'freemarkerConfig' defined in class path resource [springmvc-framework.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: freemarker.template.Configuration.<init>(Lfreemarker/template/Version;)V] with root cause
java.lang.NoSuchMethodError: freemarker.template.Configuration.<init>(Lfreemarker/template/Version;)V

 

说freemarker 版本不一至。然后找到org.freemarker 将其版本升级到2.3.21后启动项目。
