【问题描述】:
在我提出问题 - Authorization and authentication on the web application with JSF, Hibernate and Tomcat 之后,我开发了一些代码,我相信我非常接近解决方案。
首先,我正在使用 Eclipse 和 Apache Tomcat 使用 Java EE、JSF、Hibernate、MySQL 编写一个 Web 应用程序。我不使用 Spring、EJB 等。我实现了“容器管理身份验证”。我分享了该项目的部分代码。 他们有标准的简单代码来开发 SERVLET 登录。当您看着它们时,您会很容易理解。
POJO 类;
public class User {
// Primary Key
private int USER_ID;
private String USER_NAME;
private String PASSWORD;
private String FIRST_NAME;
private String LAST_NAME;
...
public User(String uSER_NAME, String pASSWORD, String fIRST_NAME,
String lAST_NAME, ...) {
super();
USER_NAME = uSER_NAME;
PASSWORD = pASSWORD;
FIRST_NAME = fIRST_NAME;
...
}
/**
* Default empty constructor needed for hibernate entity
*/
public User() {
super();
// TODO Auto-generated constructor stub
}
/**
* Getters and setters
*/
...
...
}
public class UserGroup {
// Primary Key
private int USER_GROUP_ID;
// Reference for User table - foreign key
private Set<User> USERS;
private String USER_GROUP_NAME;
private boolean ADMINISTRATOR_SCR;
private boolean USER_SCR;
private boolean PLANNING_SCR;
...
public UserGroup(Set<User> uSERS, String uSER_GROUP_NAME,
boolean aDMINISTRATOR_SCR, boolean uSER_SCR, boolean pLANNING_SCR,
...) {
super();
USERS = uSERS;
USER_GROUP_NAME = uSER_GROUP_NAME;
ADMINISTRATOR_SCR = aDMINISTRATOR_SCR;
...
}
/**
* Default empty constructor needed for hibernate entity
*/
public UserGroup() {
// TODO Auto-generated constructor stub
}
/**
* Getters and setters
*/
...
...
}
休眠映射文件;

web.xml 配置;

server.xml tomcat 配置;
<Realm className="org.apache.catalina.realm.JDBCRealm"
driverName="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/authentication_db"
connectionName="..." connectionPassword="..."
userTable="user" userNameCol="USER_NAME" userCredCol="PASSWORD"
userRoleTable="usergroup" roleNameCol="USER_GROUP_NAME" />
最后是登录功能;
public String login(){
HttpServletRequest request = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
try {
//Login via the Servlet Context
request.login(getLoginName(), getLoginPass());
return "success";
} catch (ServletException e) {
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR, "Invalid Login", null));
e.printStackTrace();
}
return "failure";
}
在我将记录放在用户表和用户组上并运行应用程序后,它看起来工作正常。但是,我收到此错误;
2014 年 16 月 16 日下午 4:38:48 org.apache.catalina.realm.JDBCRealm getRoles
严重:执行身份验证时出现异常

请帮帮我!
编辑:

【问题讨论】:
-
你能把MySql的表定义也贴出来吗?
-
我添加了MySQL表信息。它们都是利用hibernate的持久化特性生成的。
