java - 解析 struts.xml 时在 Struts 2 中不使用速度的异常

Question

这是我的struts.xml 文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>

<constant name="struts.devMode" value="true" /> 
<constant name="struts.enable.DynamicMethodInvocation" value="true"/>
<constant name="struts.objectFactory" value="org.apache.struts2.spring.StrutsSpringObjectFactory" />  

<package name="Authentiate" extends="struts-default">

<global-results>

<result name="error">/error.jsp</result>

</global-results>

<action name="loginAuthenticate*" class="com.authenticate.actions.LoginAuthenticate" method="{1}">

<result name="success">/welcome.jsp</result>
<result name="error">/error.jsp</result>
<result name="redirectRegister" type="redirect">/registration.jsp</result>

</action>

</package>

我没有使用速度模板，但我收到以下错误。

java.lang.RuntimeException: com.opensymphony.xwork2.inject.DependencyException: com.opensymphony.xwork2.inject.ContainerImpl$MissingDependencyException: No mapping found for dependency [type=org.apache.struts2.views.velocity.VelocityManager, name='default'] in public void org.apache.struts2.osgi.OsgiConfigurationProvider.setVelocityManager(org.apache.struts2.views.velocity.VelocityManager). - Class: com.opensymphony.xwork2.inject.ContainerBuilder

Answer 1

首先尝试使用默认类型 dispatcher 明确指出结果类型:

<result name="success" type="dispatcher">/welcome.jsp</result>
<result name="error" type="dispatcher">/error.jsp</result>
<result name="redirectRegister" type="redirect">/registration.jsp</result>

如果这没有帮助，看起来有一些无法解决的 struts 依赖关系。根据this bug在 apache 的 bugtracker 中，您应该将 VelocityManager bean 添加到您的 struts.xml:

<bean class="org.apache.struts2.views.velocity.VelocityManager" name="default" optional="true" />
