下载struts2.5.26jar包

官网下载

更新jar

新增或替换

asm-7.3.1.jar asm-analysis-7.3.1.jar asm-commons-7.3.1.jar asm-tree-7.3.1.jar commons-lang3-3.8.1.jar commons-io-2.6.jar commons-fileupload-1.4.jar javassist-3.20.0-GA.jar log4j-api-2.12.1.jar ognl-3.1.28.jar struts2-core-2.5.26.jar struts2-json-plugin-2.5.26.jar struts2-junit-plugin-2.5.26.jar struts2-spring-plugin-2.5.26.jar xpp3_min-1.1.4c.jar xstream-1.4.11.1.jar xmlpull-1.1.3.1.jar 

删除

xwork-core-2.3.32.jar 2.5.X已把xwork-core整合到struts2-core，所以删除 

修改web.xml

<filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> 

修改weblogic.xml(如果有)

新增session-descriptor

<weblogic-web-app> <session-descriptor> <cookie-name>JSESSIONID1</cookie-name> </session-descriptor> </weblogic-web-app> 

修改struts.xml

2.1–》2.5

<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN" "http://struts.apache.org/dtds/struts-2.5.dtd"> 

新增配置

• package标签添加strict-method-invocation=”false”和下列标签。
• global-allowed-methods：放最下面，过滤自定义action的方法，不然不能访问
• 如果已经配置struts.properties，可不加constant标签

<constant name="struts.enable.DynamicMethodInvocation" value="true"/> <constant name="struts.enable.SlashesInActionNames" value="true"/> <constant name="struts.action.extension" value="do" /> <package extends="struts-default" strict-method-invocation="false"> <global-results> </global-results> <global-allowed-methods>regex:.*</global-allowed-methods> </package> 

修改struts.xml的result-types配置

• 注释部分为struts2.3.32配置

如果重写了ParametersInterceptor.java类

原方法

protected Map<String, Object> retrieveParameters(ActionContext ac) { 
    return ac.getParameters(); } 

新方法

protected Map<String, String[]> retrieveParameters(ActionContext ac) { 
    HttpParameters httpParameters = ac.getParameters(); return httpParameters.toMap(); }
