我想在struts2 中实现基于表单的身份验证。
我的目录结构是:
我的 web.xml:
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<security-constraint>
<display-name>Example Security Constraint</display-name>
<web-resource-collection>
<web-resource-name>Protected Area</web-resource-name>
<url-pattern>/protected/*</url-pattern>
<http-method>DELETE</http-method>
<http-method>GET</http-method>
<http-method>POST</http-method>
<http-method>PUT</http-method>
</web-resource-collection>
<auth-constraint>
<role-name>manager</role-name>
</auth-constraint>
<user-data-constraint>
<transport-guarantee>NONE</transport-guarantee>
</user-data-constraint>
</security-constraint>
<!-- Default login configuration uses form-based authentication -->
<login-config>
<auth-method>FORM</auth-method>
<realm-name>Example Form-Based Authentication Area</realm-name>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/error.jsp</form-error-page>
</form-login-config>
</login-config>
<security-role>

<role-name>

</role-name>
</security-role>
<session-config>
<session-timeout>

</session-timeout>
</session-config>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
我的 login.jsp :
<form method="POST" action="j_security_check" >
<table border="0" cellspacing="5">
<tr>
<th align="right">Username:</th>
<td align="left"><input type="text" name="j_username"></td>
</tr>
<tr>
<th align="right">Password:</th>
<td align="left"><input type="password" name="j_password"></td>
</tr>
<tr>
<td align="right"><input type="submit" value="Log In"></td>
<td align="left"><input type="reset"></td>
</tr>
</table>
</form>
struts中的动作:
<action name= "j_security_check" class="action.LoginAction" >
<result name="success" >protected/index.jsp</result>
<result name="error" > error.jsp </result>
<result name="input" > login.jsp</result>
</action>
我的 LoginAction.java
public class LoginAction extends ActionSupport {
String j_username, j_password;
public String getJ_password() {
return j_password;
}
public void setJ_password(String j_password) {
this.j_password = j_password;
}
public String getJ_username() {
return j_username;
}
public void setJ_username(String j_username) {
this.j_username = j_username;
}
@Override
public String execute() throws Exception {
if (getJ_username().equals(getJ_password())) {
return SUCCESS;
} else {
this.addActionError("Error..!");
return ERROR;
}
}
@Override
public void validate() {
if ((getJ_username() == null) || (getJ_username().length() == 0)) {
this.addActionError("Username Empty");
}
if ((getJ_password() == null) || (getJ_password().length() == 0)) {
this.addActionError("Password Empty");
}
}
有了这个,当我插入相同的登录名和密码时,我被重定向到错误页面..
有人可以提供一个很好的链接吗?
该示例应包含一个受保护的文件夹,一个用于登录的操作类。
谢谢..
