[huangheping520hhp]

域驱动模式出错，取不到页面的值，页面的值也无法注入到action里的实体类里

action代码：


private String username;
private String password;

private User user = new User();

private UserService userService;
public String isUser()throws Exception{
boolean isuser=userService.isUser(user.getUsername(), user.getPassword());
if(isuser)
super.addActionMessage(username+"登录成功!");
else
super.addActionMessage(username+"登录失败!");
return SUCCESS;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public UserService getUserService() {
return userService;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
@Autowired
public void setUserService(UserService userService) {
this.userService = userService;
}


jsp代码：

<body>
<form action="user/usermanage!isUser.action" method="post">
用户名:<input type="text" name="user.username"><br>
密码:<input type="password" name="user.password"><br>
<input type="submit" value="提交">
</form>
</body>

[酔笙梦死]

好bug

[基拉]

在哪里改了个user2啊！？我的是有name就会扔掉password。。。实体里只能收到其中一个值。。。

很奇怪的也。。。

[小时候可坏了]

private User user = new User();

private UserService userService;


改为：

private User user;

private UserService userService = new UserService();

[haiercs]

用户名:<input type="text" name="user.username"><br>
密码:<input type="password" name="user.password"><br>
改为
用户名:<input type="text" name="username"><br>
密码:<input type="password" name="password"><br>

[Tommyzcg]

看看你的User类里有没有password这个属性，有get set 方法吗

[brightyq]

private User user = new User();
改成
private User user；

[frank825413747]

用户名:<input type="text" name="user.username"><br>
密码:<input type="password" name="user.password"><br>
改为
用户名:<input type="text" name="username"><br>
密码:<input type="password" name="password"><br>

[dengsilinming]

应该是页面出的问题，1L的解释感觉比较正确

[huangheping520hhp]

用户名:<input type="text" name="username"><br>
密码:<input type="password" name="password"><br>

属性注入没有问题，可以成功，
我现在想实现user实体类注入

[huangheping520hhp]

这个是user实体类


@Entity
@Table(name="t_users")
public class User {
private int id;
private String username;
private String password;

@Id @GeneratedValue(generator="system-uuid")
@GenericGenerator(name="system-uuid", strategy="uuid")
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
@Column(nullable=true, length=20)
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
@Column(nullable=true, length=20)
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}

[zuxianghuang]

要用<s:标签吧，你用的是html

[huangheping520hhp]

不是标签的问题
我另外写一个user，可以注入了，原来的user有注解，不明白用注解后，user怎么识别不了？

[huangheping520hhp]

FUCK，user改成user2就可以了，什么BUG？

[huangheping520hhp]

[Quote=引用 13 楼 的回复:]
private User user = new User();

private UserService userService;


改为：

private User user;

private UserService userService = new UserService();
[/Quote]

userService是spring注入的

[brightyq]

正因为是注入的，
private User user = new User(); 这里就不应该是new 出来的。

private UserService userService; 这句不应该动。

我在3楼的的回复，楼主试了不好用吗？
你说的改成user2，是改哪个地方的？
