freemarker.template.Configuration.(Lfreemarker/template/Version;)V

Spring3.x升级到Spring4.x时，后台报错

Caused by: java.lang.NoSuchMethodError: freemarker.template.Configuration.<init>(Lfreemarker/template/Version;)V

原因是freemaker版本不兼容，将其修改为如下版本即可

  <dependency>
            <groupId>org.freemarker</groupId>
            <artifactId>freemarker</artifactId>
            <version>2.3.28</version>
  </dependency>
