struts2中的jsp值传到后台action接收的三种方法由刀豆文库小编整理，希望给你工作、学习、生活带来方便，猜你可能喜欢“后台如何接收ajax传值”。
1.Action中的属性与表单中的属性一致就可以
JSP中的表单
用户名:
密码:
Action中的属性
publicclaLoginActionextends ActionSupport {
private String username;
private String paword;
public String getUsername(){
returnusername;}
publicvoid setUsername(String username){
this.username = username;}
public String getPaword(){
returnpaword;} publicvoid setPaword(String paword){
this.paword = paword;}
public String execute(){
if(username.equalsIgnoreCase(“aaa”)&&paword.equals(“aaaaaa”)){
returnSUCCESS;}
else{
returnERROR;} } }
2.使用一个VO类
在表单中提交的属性名改为user.username
用户名:
密码:
LoginAction中的属性改为user
publicclaLoginActionextends ActionSupport{ private User user;
public User getUser(){
returnuser;}
publicvoid setUser(User user){
this.user = user;}
public String execute(){
if(user.getUsername().equalsIgnoreCase(“aaa”)&&user.getPaword().equals(“aaaaaa”)){
returnSUCCESS;}
else{
returnERROR;} } }
3.使用Struts2中的ModelDriven数据模式
Action类要实现一个泛型接口,前台表单与1相同
publicclaLoginActionextends ActionSupport implements ModelDriven {
private User user = new User();
public String execute(){
if(user.getUsername().equalsIgnoreCase(“aaa”)&&user.getPaword().equals(“aaaaaa”)){
returnSUCCESS;}
else{
returnERROR;} }
public User getModel(){
returnuser;} }
