Question

IDE版本：struts2.5.8 + spring4.3.6 + hibernate5.2.8。我是Java Web的新工作者。我仔细检查了我的代码后，但行动无法正常工作。每次我在Tomcatv9.0中运行我的代码时，我的chrome web浏览器都会显示“HTTP Status 404”类型状态报告。 description：请求的资源不可用。

行动代码：

    private String username;
    private String password;
    private String password2;

    public UserManager getUm() {
    return um;

public void setUm(UserManager um) {
    this.um = um;
}
@Override

    User u = new User();
    u.setUsername(username);
    u.setPassword(password);        
    if(um.exists(u)) {         
        return "fail";
    }
    um.add(u);      
    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 String getPassword2() {
    return password2;
}
public void setPassword2(String password2) {
    this.password2 = password2;
}

}

Answer 1

今天，我再次检查我的代码，并在register.jsp页面代码中找到错误代码，如下所示：

<body>
<form method="post" action="user.Action">
    UserName:<input type="text" name="username"><br>
    Password:<input type="text" name="password"><br>
    Password2:<input type="password" name="password2"><br>
    <input type="submit" value="Login"/>
</form>

更改大写＆＃34; user.Action＆＃34;小写＆＃34; user.action＆＃34;，然后struts动作可以工作。

<body>
<form method="post" action="user.action">
    UserName:<input type="text" name="username"><br>
    Password:<input type="text" name="password"><br>
    Password2:<input type="password" name="password2"><br>
    <input type="submit" value="Login"/>
</form>

为什么我的动作不能在我的javaWeb项目中工作？
