您好我正在尝试在我的应用程序上放置一个登录页面。 我的login.jsp是
<form name='f' action="<c:url value='j_spring_security_check' />"
method='POST'>
<table>
<tr>
<td>User:</td>
<td><input type='text' name='j_username' value=''>
</td>
</tr>
<tr>
<td>Password:</td>
<td><input type='password' name='j_password' />
</td>
</tr>
<tr>
<td colspan='2'><input name="submit" type="submit"
value="submit" />
</td>
</tr>
<tr>
<td colspan='2'><input name="reset" type="reset" />
</td>
</tr>
</table>
</form>
</body>
</html>
登录控制器
@Controller 公共类LoginController {
@RequestMapping("/user/login.do")
public ModelAndView handleLoginForm(HttpServletRequest request) {
String errParam = request.getParameter("error");
ModelAndView mv = new ModelAndView("login");
if(errParam != null) {
mv.addObject("error", "Benutzer oder Kennwort unzulässig");
}
return mv;
}
}

现在我什么时候点击http://localhost:8080/springhibernate/user/login.do 它显示了我的登录页面，但是当点击登录时它总是给我错误
请求的资源（/ springhibernate / user / j_spring_security_check）不可用。 该页面将重定向到http://localhost:8080/springhibernate/user/j_spring_security_check
请帮我解决这个问题并建议我如何在我的应用程序中使用这个登录功能我坚持使用

我使用单独的登录表单设置相同，但在登录操作时，会调用以下方法：
（见编辑）
不太确定它是如何工作的，但显然它是必要的： http://ocpsoft.com/java/jsf-java/spring-security-what-happens-after-you-log-in/
编辑：
我的表格：
<h:form id="loginForm" prependId="false">
<label for="j_username"><h:outputText value="Username:" /><br />
</label>
<h:inputText id="j_username" required="true">
</h:inputText>
<br />
<br />
<label for="j_password"><h:outputText value="Password:" /><br />
</label>
<h:inputSecret id="j_password" required="true">
</h:inputSecret>
<br />
<br />
<label for="_spring_security_remember_me"> <h:outputText
value="Remember me" /> </label>
<h:selectBooleanCheckbox id="_spring_security_remember_me" />
<br />
<h:commandButton type="submit" id="login"
action="#{loginBean.doLogin}" value="Login" />
</h:form>
登录bean：
@SessionScope
public class LoginBean implements Serializable
{
private String j_username;
private String j_password;
private String _spring_security_remember_me;
public String getJ_username() {
return j_username;
}
public void setJ_username(String j_username) {
this.j_username = j_username;
}
public String getJ_password() {
return j_password;
}
public void setJ_password(String j_password) {
this.j_password = j_password;
}
public String get_spring_security_remember_me() {
return _spring_security_remember_me;
}
public void set_spring_security_remember_me(String _spring_security_remember_me) {
this._spring_security_remember_me = _spring_security_remember_me;
}
// This is the action method called when the user clicks the "login" button
public String doLogin() throws IOException, ServletException
{
ExternalContext context = FacesContext.getCurrentInstance().getExternalContext();
RequestDispatcher dispatcher = ((ServletRequest) context.getRequest())
.getRequestDispatcher("/j_spring_security_check");
dispatcher.forward((ServletRequest) context.getRequest(),
(ServletResponse) context.getResponse());
FacesContext.getCurrentInstance().responseComplete();
// It's OK to return null here because Faces is just going to exit.
return null;
}
}

以下是我的工作配置供您参考。它们似乎完全相同。这些是针对Spring 3.0的。没试过2.x，但认为这可能对你有所帮助。
