配置struts2.0.6+spring2.0.3+hibernane3备忘
花了2个小时终于配置好struts2.0.6+spring2.0.3+hibernane3，为自己庆祝一下，分享一下经验
一、struts2。
跟webwork配置基本一致，主要是struts2.properties和struts.xml 2个配置文件，我的struts2.properties如下配置：
- <listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener>
Spring配置文件添加
<bean id="LoginAction" name="code"> <action name="login" name="code"> <bean id="LoginAction" name="code"> <bean name="code"> <constant name="objectFactory" value="spring"></constant>[b]<action name="Login" name="code"><beans> <bean id="helloWorld" name="code"><%@ page contentType="text/html; charset=UTF-8" %><%@ taglib prefix="s" uri="/struts-tags" %><html><head> <title>Sign On</title></head><body><s:form action="Login"> <s:textfield key="username"/> <s:password key="password" /> <s:submit/></s:form></body></html>
Login-validation.xml如下：
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.2//EN" "http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd"><validators> <field name="username"> <field-validator type="requiredstring"> <message key="requiredstring"/> </field-validator> </field> <field name="password"> <field-validator type="requiredstring"> <message key="requiredstring"/> </field-validator> </field></validators>
Login.java代码就不写了，因为程序根本就没进这个Action。每次提交时进行验证，然后返回到原拉的Login界面！如果不把action交给spring管理的话就能正确提交，为什么？<web-app id="WebApp_9" version="2.4"

struts.xml:

struts.properties:
struts.devMode = true
struts.enable.DynamicMethodInvocation = false
#struts.objectFactory = spring 这里有个问题，在struts.xml中已经定义了plugin，在这里还需要再定义这个吗？
以上是我的整合spring的配置文件，但是启动tomcat的时候会报如下错误：

log4j:WARN Please initialize the log4j system properly.

以下是我加入的jar包：
antlr-2.7.6.jar
asm-2.2.1.jar
cglib-nodep-2.1_3.jar
commons-beanutils-1.7.1-20061106.jar
commons-collections-3.2.jar
commons-dbcp-1.2.1.jar
commons-digester-1.7.jar
commons-lang-2.3.jar
commons-logging-1.1.jar
dom4j-1.6.1.jar
freemarker-2.3.8.jar
hibernate-3.2.0.ga.jar
jstl-1.1.2.jar
jta-1.0.1B.jar
jtds-1.2.jar
log4j-1.2.8.jar
ognl-2.6.11.jar
spring-2.0.jar
struts2-core-2.0.6.jar
struts2-spring-plugin-2.0.6.jar
xwork-2.0.1.jar
tomcat包就不列出来了
起初我看到是log4j的错误时，我就把web.xml中的log4j去掉，但是启动还报这个错误，我有点困惑，为何一加入spring之后就会报这个错误，为何去掉了log4j后还会报log4j的错误。value="/WEB-INF/classes/struts.xml"
/>
</plug-in>
那么strtus2提供的struts2-spring-plugin-2.0.8.jar是干嘛用的呢?
