struts 环节配置

因项目需求边学边开发,故特此记录下来,以便日后再次使用

环境分为3个部分
1.web.xml(WEB-INF根目录)
    1.添加filter节点           

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

    2.添加filter-mapping节点(过滤标签)

<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

    3.listener节点(可不加,tomcat启动时直接运行)

<listener> 
		<listener-class>Entity.SqlEntity</listener-class>
	</listener>

    4.完整xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
	http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

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

	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<listener> 
		<listener-class>Entity.SqlEntity</listener-class>
	</listener>
	
</web-app>

2.struts.xml(src根目录)
    1.默认结点

 <package name="struts" namespace="/" extends="struts-default">
		<action name="UserCheck" class="Action.UserCheckAction" method="GetUserCheckList">
			<result name="success">
				UserCheck.jsp
			</result>
			<result name="input">
				login.jsp
			</result>
		</action>
	</package>

        
    2.json节点(ajax使用)

	<package name="struts1" namespace="/" extends="json-default">
		<action name="SetUser" class="Action.UserCheckAction" method="text">
			<result name="success" type="json">
				<param name="root">SqlData</param>
			</result>
		</action>
	</package>

            
     3.多个struts.xml

<include file="struts-code.xml"></include>

       
3.BaseAction.java类(用于其他action继承)
     

package Action;

import java.util.Map;

import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.apache.struts2.interceptor.ApplicationAware;
import org.apache.struts2.interceptor.ParameterAware;
import org.apache.struts2.interceptor.RequestAware;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;
import org.apache.struts2.interceptor.SessionAware;
import org.apache.struts2.util.ServletContextAware;

import com.opensymphony.xwork2.ActionSupport;

public class BaseAction extends ActionSupport implements RequestAware,
		SessionAware, ServletContextAware, ParameterAware, ServletRequestAware,
		ServletResponseAware, ApplicationAware {
	private static final long serialVersionUID = 5952689219411916553L;
	protected HttpServletRequest request;
	protected HttpServletResponse response;
	protected HttpSession session;
	protected ServletContext application;

	@SuppressWarnings("unchecked")
	protected Map requestMap;
	@SuppressWarnings("unchecked")
	protected Map sessionMap;
	@SuppressWarnings("unchecked")
	protected Map applicationMap;
	@SuppressWarnings("unchecked")
	protected Map parameterMap;

	public void setRequest(Map<String, Object> arg0) {
		this.requestMap = arg0;
	}

	public void setSession(Map<String, Object> arg0) {
		this.sessionMap = arg0;
	}

	public void setServletContext(ServletContext arg0) {
		this.application = arg0;
	}

	public void setParameters(Map<String, String[]> arg0) {
		this.parameterMap = arg0;
	}

	public void setServletRequest(HttpServletRequest arg0) {
		this.request = arg0;
		this.session = request.getSession();
	}

	public void setServletResponse(HttpServletResponse arg0) {
		this.response = arg0;
	}

	public void setApplication(Map<String, Object> arg0) {
		this.applicationMap = arg0;
	}
}
