这些天我遇到一个问题,我无法弄清楚,所以请帮助我......
我的实体: Utilisateur
这是一个法语单词,意思是用户
@Entity
@Inheritance(strategy = InheritanceType.JOINED)
public class Utilisateur implements Serializable
{
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
protected int id;
protected String login;
protected String password;
protected String nom;
protected String prenom;
protected String email;
protected String username;}
@OneToOne(mappedBy="user", cascade={CascadeType.ALL})
private Role role;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return login;
}
public void setUsername(String username) {
this.username = username;
}
public String getLogin() {
return login;
}
public void setLogin(String login) {
this.login = login;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getNom() {
return nom;
}
public void setNom(String nom) {
this.nom = nom;
}
public String getPrenom() {
return prenom;
}
public void setPrenom(String prenom) {
this.prenom = prenom;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public Role getRole() {
return role;
}
public void setRole(Role role) {
this.role = role;
}
}
和一个Role
实体。
在我的网络应用程序中,有一个控制器可以显示例如有关学生的信息(Etudiant
法语)
@EJB(mappedName = "Etudiant.EtudiantFacade")
EtudiantFacade etudiantF;
// Affiche le detail d'un Etudiant (show the infomations of the student)
@RequestMapping(value = "/Etudiant/{idEtudiant}/info")
public ModelAndView detail(@PathVariable String idEtudiant, Model m) {
m.addAttribute("etudiant",
etudiantF.trouver(Integer.parseInt(idEtudiant)));
return new ModelAndView("EtudiantInformation", "null", null);
}
CustomUseDetailService
我直接使用实体实现了我自己的Utilisateur
。
@Override
public UserDetails loadUserByUsername(String username)
throws UsernameNotFoundException, DataAccessException {
// TODO Auto-generated method stub
System.out.println("!!!!!!!!!!!!!!!!!");
System.out.println(username);
boolean enabled = true;
boolean accountNonExpired = true;
boolean credentialsNonExpired = true;
boolean accountNonLocked = true;
Utilisateur etudiant = etudiantF.trouverParLogin(username);
return new User(etudiant.getLogin(), etudiant.getPassword(), enabled,accountNonExpired,credentialsNonExpired,accountNonLocked,getAuthorities(etudiant.getRole().getRole()));
}
我的security.xml如下:
<http auto-config="true" use-expressions="true">
<intercept-url pattern="/app/Login" access="permitAll"/>
<intercept-url pattern="/app/*" access="hasAnyRole('ROLE_ADMIN','ROLE_USER')"/>
<form-login login-page="/app/Login"
authentication-success-handler-ref="authenticationSuccessHandler"/>
<logout logout-url="/app/Logout" logout-success-url="/"/>
</http>
<authentication-manager alias="authenticationManager">
<authentication-provider user-service-ref="customUserDetailsService"/>
</authentication-manager>
最后我的问题是:对于一个学生,他的id是1,他的用户名是stu1,要控制这个id为1的学生只能访问他自己的页面信息 /ProjetName/Student/{studentId}/Info
我该如何编写代码@PreAuthorize
,我已经看到了spring表单中的文档,有这样的例子@PreAuthorize(#contract.name = principal.username)
,因为principal中有一个属性username,但是在这里,我需要的是Id,我@RequestMapping(value = "/Etudiant/{idEtudiant}/info")
用来匹配学生而不是用户名。那么我该如何解决呢?非常感谢...我找不到教程。
