项目结构如图：
主要类文件如下：
AdminAction.java
public class AdminAction extends ActionSupport{
/**
*
*/
private static final long serialVersionUID = 1L;
private Admin admin;
public Admin getAdmin() {
return admin;
}
public void setAdmin(Admin admin) {
this.admin = admin;
}
public String Login(){
// 使用request存值
ActionContext actionContext = ActionContext.getContext();
actionContext.put("Lili", "你好！");
// 使用session存值
actionContext.getSession().put("Jenny", "你好Jenny");
// 使用application存值
actionContext.getApplication().put("Nike", "谢谢Nike");
// 存入对象
// 使用request存值
actionContext.put("admin", admin);
// 使用session存值
actionContext.getSession().put("admin", admin);
// 使用application存值
actionContext.getApplication().put("admin", admin);
return "adminaction_login";
}
public String save(){
System.out.println("保存成功！！！！！！");
return "adminaction_save";
}
public String delete(){
System.out.println("删除成功！！！！！！");
return "adminaction_delete";
