Struts2的使用注解配置Action（零配置）

忘是亡心i 2022-08-14 02:48 226阅读 0赞

1，首先引入struts2注解的jar包：struts2-convention-plugin.jar

<dependency>
    		<groupId>org.apache.struts</groupId>
    		<artifactId>struts2-convention-plugin</artifactId>
    		<version>${struts2-version}</version>
    	</dependency>

2，classpath下struts.xml配置文件

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE struts PUBLIC
    	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    	"http://struts.apache.org/dtds/struts-2.3.dtd">
    <struts>
    
    	
    	
    	
    	   
        <constant name="struts.serve.static.browserCache" value="false" />
    	 
    	<constant name="struts.configuration.xml.reload" value="true"/>
    	  	
    	 
        <constant name="struts.i18n.encoding" value="UTF-8"/> 
    	
    	<constant name="struts.action.extension" value="html"/>
    	
    	<constant name="struts.ui.theme" value="simple" />
    	
    	<constant name="struts.multipart.maxSize" value="2097152000"></constant>
    	
    	<constant name="struts.objectFactory" value="spring" /> 
    	  
        <constant name="struts.enable.DynamicMethodInvocation" value="false"/> 
    	
    
    	
    	<constant name="struts.convention.result.path" value="/WEB-INF/jsp" />
    	
    	
    	
    	<constant name="struts.convention.package.locators"  value="action,actions,struts,struts2,controller" /> 
    	
    	<constant name="struts.convention.action.suffix"  value="Action" /> 
    	
    	
    	
    	
        
        
    	<package name="mypackage" extends="json-default">
    		
    		
    		
    		
    		
    		
    		
    		<global-results>
    			
    			<result type="json" name="ajax">
    				<param name="root">message</param>
    			</result>
    			
    			<result type="json" name="ajax2">
    				<param name="root">message2</param>
    			</result>
    			
    			<result type="json" name="jsonResult">
    				<param name="root">jsonMap</param>
    			</result>
    			
    			<result name="downloadFiles" type="stream">
    				
    				<param name="contentType">application/octet-stream;charset=UTF-8</param>
    				<param name="inputName">inputStreamFile</param>
    				
    				<param name="contentDisposition">attachment;filename=${fileName}</param>
    				
    				<param name="bufferSize">1024</param>
    			</result>
    			
    			<result name="index" type="redirect">/index.jsp</result>
    			
    			<result name="loginUI">/login.jsp</result>
    			
    			<result name="clientMessage">/message.jsp</result>
    			
    			<result name="error">/error.jsp</result>
    		</global-results>
    		
    		
    		
    	</package>
    	
    	
    	
    	
    </struts>

3,action中写法

controller包下

package cn.hl.s2sh.user.controller;
    
    
    
    import net.sf.ehcache.Cache;
    
    import org.apache.commons.logging.Log;
    import org.apache.commons.logging.LogFactory;
    import org.apache.struts2.convention.annotation.Action;
    import org.apache.struts2.convention.annotation.ExceptionMapping;
    import org.apache.struts2.convention.annotation.ExceptionMappings;
    import org.apache.struts2.convention.annotation.Namespace;
    import org.apache.struts2.convention.annotation.ParentPackage;
    import org.apache.struts2.convention.annotation.Result;
    import org.apache.struts2.convention.annotation.Results;
    import org.springframework.context.annotation.Scope;
    import org.springframework.stereotype.Controller;
    
    import cn.hl.s2sh.base.controller.struts2.BaseAction;
    import cn.hl.s2sh.base.plugins.cache.CachedManager;
    
    /**
     * @Description: user控制器
     * @author hl
     * @date 2014-11-18 下午11:10:21
     *
     */
    @Controller
    @Scope("prototype")
    @ParentPackage("mypackage")
    @Results({
    	@Result(name="test1",location="test.jsp"),
    	@Result(name="test2",location="/WEB-INF/jsp/test2.jsp"),
    	@Result(name="main_postTalk",type="redirectAction",location="main_mindex",params={"uid","${uid}"})
    })
    @ExceptionMappings({@ExceptionMapping(exception = "java.lange.RuntimeException", result = "error") })
    @Namespace(value="/u")
    public class UserAction extends BaseAction{
    	
    	
    	//log4j
    	private static final Log log = LogFactory.getLog(UserAction.class);
    	
    	
    	
    	
    	
    	@Action("/test1")
    	public String test1(){
    		
    		CachedManager.putObjectCache("phoneCode", "a", "aaa");
    		Cache c = CachedManager.getCache("phoneCode");
    		Cache c2 = CachedManager.getCache("phoneCode2");
    		System.out.println("--------test1---1");
    		//log.debug("--manager-" + manager);
    		
    			
    		
    		return "test1";
    	}
    	
    	
    	
    	
    	
    	@Action(value="test2")
    	public String test2(){
    		
    		String s = (String) CachedManager.getObjectCache("phoneCode", "a");
    		
    		System.out.println(s);
    		
    		
    		CachedManager.remove("phoneCode", "a");
    		
    		System.out.println("--------test2---2");
    		
    		return "test2"; 
    	}
    	
    	
    	
    	
    	
    	
    
    }

部署启动tomcat，访问

localhost:8080/项目名/u/test1.html

localhost:8080/项目名/u/test2.html

localhost:8080/项目名/test1.html
