之前一段时间学习了springmvc+mybatis+spring框架,突然对之前的struts东西有点陌生, 所以这里简单记录下温故而知新的东西吧。
1. 首先建立一个Dynamic Web Project, 下面是我建立的StrutsDemo项目目录,使用的是maven构建的, 自己又增加了几个文件夹
2. 给出pom.xml文件:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com</groupId> <artifactId>StrutsDemo</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>StrutsDemo Maven Webapp</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.struts/struts2-core --> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-core</artifactId> <version>2.5.16</version> </dependency> <!--下面这两个插件,是注解方式必须要加载的--> <!-- https://mvnrepository.com/artifact/org.apache.struts/struts2-convention-plugin --> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-convention-plugin</artifactId> <version>2.5.16</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.struts/struts2-config-browser-plugin --> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-config-browser-plugin</artifactId> <version>2.5.16</version> </dependency> </dependencies> <build> <finalName>StrutsDemo</finalName> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.1</version> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build> </project>
3. 给出Struts.xml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> <!-- 所有匹配*.action的请求都由struts2处理 --> <constant name="struts.action.extension" value="action" /> <!-- 是否启用开发模式 --> <constant name="struts.devMode" value="true" /> <!-- struts配置文件改动后,是否重新加载 --> <constant name="struts.configuration.xml.reload" value="true" /> <!-- 设置浏览器是否缓存静态内容 --> <constant name="struts.serve.static.browserCache" value="false" /> <!-- 请求参数的编码方式 --> <constant name="struts.i18n.encoding" value="utf-8" /> <!-- 每次HTTP请求系统都重新加载资源文件,有助于开发 --> <constant name="struts.i18n.reload" value="true" /> <!-- 文件上传最大值 --> <constant name="struts.multipart.maxSize" value="104857600" /> <!-- 让struts2支持动态方法调用 --> <constant name="struts.enable.DynamicMethodInvocation" value="true" /> <!-- Action名称中是否还是用斜线 --> <constant name="struts.enable.SlashesInActionNames" value="false" /> <!-- 允许标签中使用表达式语法 --> <constant name="struts.tag.altSyntax" value="true" /> <!-- 对于WebLogic,Orion,OC4J此属性应该设置成true --> <constant name="struts.dispatcher.parametersWorkaround" value="false" /> <package name="basePackage" extends="struts-default"> </package> </struts>
4. 给出web.xml文件:
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app> <display-name>Archetype Created Web Application</display-name> <!-- add struts2 configiguration --> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> <!-- end add struts2 configuration--> <!-- 项目默认页 --> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> </web-app>
5. 给出TestAction.java文件:
package com.strutsdemo.action; import org.apache.struts2.convention.annotation.Action; import org.apache.struts2.convention.annotation.Namespace; import org.apache.struts2.convention.annotation.ParentPackage; import org.apache.struts2.convention.annotation.Result; @ParentPackage("basePackage") @Action @Namespace("/") public class TestAction { // http://localhost:8080/StrutsDemo/print!printSome.action // 这里是通过注解的方式来输出前台页面, // 大致的流程 // 1. 输入的url http://localhost:8080/StrutsDemo/print!printSome.action // 2. action定位到TestAction的printSome方法, 因为注解value="print" // 3. printSome方法返回print字符串, 而在我们注解results当中name="print",相互匹配, 所以会跳转到/page/print.jsp页面中 // 个人认为,通过注解方式可以很大程度上节省代码量,让代码更简单 @Action(value="print", results= {@Result(name="print", location="/page/print.jsp")}) public String printSome(){ System.out.println("TestAction printSome"); return "print"; } }
6. 给出print.jsp代码:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <h2>print something</h2> </body> </html>
7. 运行项目,并在浏览器中输入url: http://localhost:8080/StrutsDemo/print!printSome.action, 结果为:
print something
