1.下载strtuts2.5包

2.替换工程中的附件目录文件

a.freemarker-2.3.23.jar


b.log4j-api-2.5.jar
  

c.ognl-3.1.2.jar

h.struts2-spring-plugin-2.5-BETA3.jar

i、javassist-3.20.0-GA.jar

j、slf4j-api-1.7.12.jar

   备注:
   删除slf4j-api-1.5.2.jar对应slf4j-log4j12.jar

l、commons-lang3-3.4.jar
   commons-fileupload-1.3.2.jar
   commons-io-2.4.jar
   commons-logging-1.1.3.jar

3.添加:asm-3.3.jar
       asm-commons-3.3.jar
       asm-tree-3.3.jar


4.删除原工程“xwork-core-2.3.16.jar”

5.修改web.xml,把“<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>”修改成“<filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>”

6.修改jsp的struts标签，新版本里有两处明显区别

a.类似 <s:bean name="com.whb.common.DictItem" id="dictItem" /> 要修改成 <s:bean name="com.whb.common.DictItem" var="dictItem" />

b.类似<s:property value="result" escape="false"/>  要修改成 <s:property value="result" escapeHtml="false"/>








import org.apache.logging.log4j.Logger;
import org.apache.logging.log4j.LogManager;
private static Logger log =LogManager.getLogger(login.class);
