問題は、ログインページに移動すると、ログインするためのユーザー名/パスワードを入力すると、それらを正しく書いてもエラーが発生することです (データベースを確認し、エントリが存在します)。ロガーを使用する必要があることはわかっていますが、Hibernate で Spring Framework をまだ学習中です。
編集:
1.テストの最初の部分で、空のユーザー名/パスワードを入力しました(空/空の場合に機能します)。2番目の部分では、機能するはずのものを使用しました。
2.他のDAOはHibernateで正しく動作します（たとえば、データを正しく取得し、問題はありません）
コンソール出力は次のようになります。
-----------------------------------
User Service INVOKED

これはセッション タイムアウトの問題ですか?
ログイン コントローラからのメソッド:
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String Login(@RequestParam(value="error", required=false) boolean error,ModelMap model) {
if (error == true) {
model.put("error", "You have entered an invalid username or password!");
} else {
model.put("error", "");
}
System.out.println(error);
return "login";
}
ユーザーエンティティ:
@Entity
@Table(name = "USER")
public class User implements Serializable {
/**
*
*/
private static final long serialVersionUID = -1963505165125499005L;
private long id;
private int secGrade;
private String userName;
private String accountName;
private String password;
private String userEmail;
public User(String name,
String user_name,
String password,
String email,
int secGrade){
this.userName = name;
this.accountName = user_name;
this.password = password;
this.userEmail = email;
this.secGrade = secGrade;
}
@Id
@GeneratedValue
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public int getSecGrade() {
return secGrade;
}
public void setSecGrade(int secGrade) {
this.secGrade = secGrade;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getAccountName() {
return accountName;
}
public void setAccountName(String accountName) {
this.accountName = accountName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUserEmail() {
return userEmail;
}
public void setUserEmail(String userEmail) {
this.userEmail = userEmail;
}
}
DB エンティティの処理に使用されるプロキシ クラス:
public class UserProxyImpl implements UserProxy {
private int secGrade;
private String name;
private String user_name;
private String password;
private String email;
public UserProxyImpl() { }
public UserProxyImpl(User usr){
if( usr != null){
System.out.println("USER PROXY--- constru from "+usr.getAccountName());
this.secGrade = usr.getSecGrade();
this.name = usr.getUserName();
this.user_name = usr.getAccountName();
this.password = usr.getPassword();
this.email = usr.getUserEmail();
}
}
+ GETTERS/SETTERS
}
User obj を作成し、Authorities を追加する UserServiceImpl のメソッド:
@Override
public UserDetails loadUserByUsername(String username)
throws UsernameNotFoundException,DataAccessException {
// Declare a null Spring User
UserDetails user = null;
System.out.println("-----------------------------------");
System.out.println("User Service INVOKED");
try {
System.out.println("User Service-- searching for User:"+username);
// Search database for a user that matches the specified username
UserProxyImpl dbUser = new UserProxyImpl(userDAO.searchDB(username));
System.out.println("User Service-- UserProxyImpl instantiated");
if(dbUser.getName() != null){
System.out.println("User Service-- FOUND,"+username);
}
else{
System.out.println("User Service-- NOT FOUND,"+username);
}
// Populate the Spring User object with details from the dbUser
// getAuthorities() will translate the access level to the correct role type
System.out.println(dbUser.getName());
user = new User(
dbUser.getUser_name(),
dbUser.getPassword().toLowerCase(),
true,
true,
true,
true,
getAuthorities(new Integer(dbUser.getSecGrade()))
);
System.out.println(user.toString());
} catch (Exception e) {
System.out.println("UserService-- Error in retrieving user");
throw new UsernameNotFoundException("Error in retrieving user");
}
// Return user to Spring for processing.
return user;
}
@Override
public Collection<GrantedAuthority> getAuthorities(Integer access) {
// Create a list of grants for this user
List<GrantedAuthority> authList = new ArrayList<GrantedAuthority>(2);
// All users are granted with ROLE_USER access
authList.add(new GrantedAuthorityImpl("ROLE_USER"));
// Check if this user has admin access
// We interpret Integer(3) as an admin user
if ( access.compareTo(3) == 0) {
authList.add(new GrantedAuthorityImpl("ROLE_ADMIN"));
}
else if ( access.compareTo(2) == 0) {
authList.add(new GrantedAuthorityImpl("ROLE_MOD"));
}
// Return list of granted authorities
return authList;
}
DB からオブジェクトを取得するために使用される DAO クラス メソッド:
public User searchDB(String username){
User u = (User)this.getSessionFactory().getCurrentSession()
.createCriteria(User.class)
.add(Restrictions.eq("accountName",username))
.uniqueResult();
System.out.println("DAO-- End search");
if(u != null){
System.out.println("DAO-- Found:"+u.getUserName());
return u;
}
else{
System.out.println("DAO--Not found");
return null;
}
}
