struts2使用手册中例子

package tutorial; import java.sql.SQLException; import javax.servlet.http.HttpServletRequest; import org.apache.struts2.ServletActionContext; import com.opensymphony.xwork2.ActionContext; import com.opensymphony.xwork2.ActionSupport; public class HelloWorld extends ActionSupport { /** * */ private static final long serialVersionUID = 1L; private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } private String nextAction; public String getNextAction() { return nextAction; } public void setNextAction(String nextAction) { this.nextAction = nextAction; } public String login() throws SQLException { ActionContext context = ActionContext.getContext(); ActionContext.getContext().getSession().put("user" , "FY"); System.out.print(context.getSession().get("Name")); System.out.print("DDDD"); name = "Hello,login " + name + "!"; if(1==1)throw new java.sql.SQLException("没有数据库驱动程序"); return SUCCESS; } public String login2() { HttpServletRequest request = ServletActionContext.getRequest(); request.setAttribute("pid","123456"); String id=request.getAttribute("id")+""; System.out.print("login2"); name = "Hello,login2 " + name + "!"; setNextAction("login_login");//动态转向 return "next"; } }
