一:Struts开发步骤:
1. web项目,引入struts - jar包
2. web.xml中,引入struts的核心功能
配置过滤器
3. 开发action
4. 配置action
src/struts.xml
二:详细配置
1.引入8个jar文件
commons-fileupload-1.2.2.jar 【文件上传相关包】
commons-io-2.0.1.jar
struts2-core-2.3.4.1.jar 【struts2核心功能包】
xwork-core-2.3.4.1.jar 【Xwork核心包】
ognl-3.0.5.jar 【Ognl表达式功能支持表】
commons-lang3-3.1.jar 【struts对java.lang包的扩展】
freemarker-2.3.19.jar 【struts的标签模板库jar文件】
javassist-3.11.0.GA.jar 【struts对字节码的处理相关jar】
2.web.xml详细配置

3.开发Action(3种方式)
1种:直接继承ActionSupport

package cn.itcast.a_config;
import com.opensymphony.xwork2.ActionSupport;
public class UserAction extends ActionSupport {
// Action中业务处理方法
public String login() {
System.out.println( "UserAction.login()" );
return "success" ;
}
}
|
2种:继承Action接口

import com.opensymphony.xwork2.ActionSupport;
public class UserAction implements Action {
// Action中业务处理方法
public String login() {
System.out.println( "UserAction.login()" );
return "success" ;
}
@Override
public String execute() throws Exception {
return null ;
}
}
|
3种:不继承任何类,不实现任何接口

import com.opensymphony.xwork2.ActionSupport;
public class UserAction {
private String userName;
public void setUserName(String userName) {
this .userName = userName;
}
// Action中业务处理方法
public String login() {
System.out.println( "UserAction.login()" + userName);
return "login" ;
}
public String register() {
System.out.println( "register()" + userName);
return "register" ;
}
}

4. 配置action : src/struts.xml
