java - Spring 中未找到默认构造函数

Question

我刚刚将我的类移动到一个使用 Spring Security Authentication User 类扩展的对象，但我无法弄清楚我需要构建哪个默认构造函数!如果我输入类的参数，它会将它们转换为静态并使 hibernate 无法映射该类，如果我什么都不输入，它会抛出错误!

@Entity
@Table(name="USER") 
public class UserData extends User {


    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    int iduser;
    int accountstatus;
    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPass(String password) {
        this.password = password;
    }
     String username;
     String password;

    //Profile Data
    String nomprofile;
    String prenprofile;
    String mailprofile;
    String adressprofile;
    int phoneprofile;
    Date datenaissanceprofile;
    char sexeuser;
    String imagepath;

    public UserData() {
        super(username, password, authorities); //throws error 
    }

    public UserData(String username, 
            String password, 
            boolean enabled, 
            boolean accountNonExpired, 
            boolean credentialsNonExpired, 
            boolean accountNonLocked, 
            Collection<? extends GrantedAuthority> authorities, 
            int iduser,     
            int accountstatus,
            String nomprofile, 
            String prenprofile,
            String mailprofile,
            String adressprofile,
            int phoneprofile, 
            Date datenaissanceprofile, 
            char sexeuser,
            String imagepath) {
        super(username, password, enabled, accountNonExpired, credentialsNonExpired, accountNonLocked, authorities);
        this.username = username;
        this.password = password;
        this.iduser = iduser;
        this.accountstatus = accountstatus;
        this.nomprofile = nomprofile;
        this.prenprofile = prenprofile;
        this.mailprofile = mailprofile;
        this.adressprofile = adressprofile;
        this.phoneprofile = phoneprofile;
        this.datenaissanceprofile = datenaissanceprofile;
        this.sexeuser = sexeuser;
        this.imagepath = imagepath;
    }

    public int getIduser() {
        return iduser;
    }
    public void setIduser(int iduser) {
        this.iduser = iduser;
    }


    public int getAccountstatus() {
        return accountstatus;
    }
    public void setAccountstatus(int accountstatus) {
        this.accountstatus = accountstatus;
    }


    public String getNomprofile() {
        return nomprofile;
    }
    public void setNomprofile(String nomprofile) {
        this.nomprofile = nomprofile;
    }
    public String getPrenprofile() {
        return prenprofile;
    }
    public void setPrenprofile(String prenprofile) {
        this.prenprofile = prenprofile;
    }
    public String getMailprofile() {
        return mailprofile;
    }
    public void setMailprofile(String mailprofile) {
        this.mailprofile = mailprofile;
    }
    public String getAdressprofile() {
        return adressprofile;
    }
    public void setAdressprofile(String adressprofile) {
        this.adressprofile = adressprofile;
    }
    public int getPhoneprofile() {
        return phoneprofile;
    }
    public void setPhoneprofile(int phoneprofile) {
        this.phoneprofile = phoneprofile;
    }
    public Date getDatenaissanceprofile() {
        return datenaissanceprofile;
    }
    public void setDatenaissanceprofile(Date datenaissanceprofile) {
        this.datenaissanceprofile = datenaissanceprofile;
    }
    public char getSexeuser() {
        return sexeuser;
    }
    public void setSexeuser(char sexeuser) {
        this.sexeuser = sexeuser;
    }
    public String getImagepath() {
        return imagepath;
    }
    public void setImagepath(String imagepath) {
        this.imagepath = imagepath;
    }
}

与其从 spring-security 扩展用户类，不如实现 spring security 给出的 UserDetails 接口(interface)。请阅读下面的代码。为您的项目提供自定义 userDetailsS​​ervice 实现。我希望这对您有帮助-http://docs.spring.io/spring-security/site/docs/3.0.x/reference/technical-overview.html#d0e1613

 public class User implements UserDetails{

private UserData userData;
private List<String> roles;

public User(UserData user){
    this.userData=user;

}



public Collection<? extends GrantedAuthority> getAuthorities() {
    List<SimpleGrantedAuthority> authorities=new ArrayList<SimpleGrantedAuthority>();
    for (String role : userData.getRoles()) {
        authorities.add(new SimpleGrantedAuthority(role));
    }
    return authorities;
}

public String getPassword() {
    return user.getPassword();
}

public String getUsername() {
    // TODO Auto-generated method stub
    return user.getUsername();
}

public boolean isAccountNonExpired() {
    // TODO Auto-generated method stub
    return true;
}

public boolean isAccountNonLocked() {
    // TODO Auto-generated method stub
    return true;
}

public boolean isCredentialsNonExpired() {
    // TODO Auto-generated method stub
    return true;
}

public boolean isEnabled() {
    // TODO Auto-generated method stub
    return true;
}

}
