修改web.xml

</filter>

修改weblogic.xml(如果有)

新增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

<struts>
	<package name="struts-default" abstract="true"  strict-method-invocation="false">
		<result-types>
            <result-type name="chain" class="com.opensymphony.xwork2.ActionChainResult"/>
            
            <result-type name="dispatcher" class="org.apache.struts2.result.ServletDispatcherResult" default="true"/>

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();
}
