出了什么问题：我尝试使用Spring Security实现登录。我使用的是Spring Security的默认端点login。我一直收到500，我相信这是由于错误的关节造成的，因为当我打印时
public Set<Role> getRoles() {
System.out.println("roles");
System.out.println(roles);
return roles;
}
角色为空。 ＆＃39;将在问题的最后显示我的堆栈跟踪。
我想拥有的内容：正确的工作联接。
我的代码 加入：
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
@JoinTable(
name = "userrole",
joinColumns = @JoinColumn(name = "iduser"),
inverseJoinColumns = @JoinColumn(name = "roleid"))
private Set<Role> roles;
整个用户模型：
@Entity
@Table(name = "user_1")
public class Users {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "iduser")
private Integer id;
@Column(name="id_points")
private Integer idPoints;
@Column(name="username")
private String userName;
@Column(name="isblocked")
private Boolean isBlocked;
@Column(name="email")
private String email;
@Column(name="lastname")
private String lastName;
@Column(name="firstname")
private String firstName;
@Column(name="password")
private String password;
@Column(name="token")
private String token;
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
@JoinTable(
name = "userrole",
joinColumns = @JoinColumn(name = "iduser"),
inverseJoinColumns = @JoinColumn(name = "roleid"))
private Set<Role> roles;
public Users() {
}
public Users(Users users) {
this.id = users.getId();
this.idPoints = users.getIdPoints();
this.userName = users.getUserName();
this.isBlocked = users.getBlocked();
this.email = users.getEmail();
this.lastName = users.getLastName();
this.firstName = users.getFirstName();
this.password = users.getPassword();
this.token = users.getToken();
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public Integer getIdPoints() {
return idPoints;
}
public void setIdPoints(Integer idPoints) {
this.idPoints = idPoints;
}
public String getUserName() {
System.out.println(userName);
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public Boolean getBlocked() {
return isBlocked;
}
public void setBlocked(Boolean blocked) {
isBlocked = blocked;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getToken() {
return token;
}
public void setToken(String token) {
this.token = token;
}
public Set<Role> getRoles() {
System.out.println("roles");
System.out.println(roles);
return roles;
}
public void setRoles(Set<Role> roles) {
this.roles = roles;
}
}
CustomUsersDetails：
package com.shareabook.model;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import java.util.Collection;
import java.util.stream.Collectors;
public class CustomUserDetails extends Users implements UserDetails {
public CustomUserDetails(final Users users) {
super(users);
}
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
return getRoles()
.stream()
.map(role -> new SimpleGrantedAuthority("ROLE_" + role.getRole()))
.collect(Collectors.toList());
}
@Override
public String getPassword() {
return super.getPassword();
}
@Override
public String getUsername() {
return super.getUserName();
}
@Override
public boolean isAccountNonExpired() {
return true;
}
@Override
public boolean isAccountNonLocked() {
return true;
}
@Override
public boolean isCredentialsNonExpired() {
return true;
}
@Override
public boolean isEnabled() {
return true;
}
}
角色模型
@Entity
@Table(name = "role")
public class Role {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "roleid")
private Integer role_id;
@Column(name = "role")
private String role;
public Role() {
}
public Integer getRole_id() {
return role_id;
}
public void setRole_id(Integer role_id) {
this.role_id = role_id;
}
public String getRole() {
System.out.println("role");
System.out.println(role);
return role;
}
public void setRole(String role) {
this.role = role;
}
}
我如何创建数据库：
CREATE TABLE Role (
roleId INTEGER NOT NULL,
role VARCHAR NOT NULL,
CONSTRAINT pkrole PRIMARY KEY (roleId)
);
CREATE SEQUENCE user_1_iduser_seq;
CREATE TABLE User_1 (
idUser INTEGER NOT NULL DEFAULT nextval('user_1_iduser_seq'),
id_points INTEGER NOT NULL,
userName VARCHAR NOT NULL,
isBlocked BOOLEAN DEFAULT False NOT NULL,
email VARCHAR NOT NULL,
lastName VARCHAR NOT NULL,
firstName VARCHAR NOT NULL,
password VARCHAR NOT NULL,
token VARCHAR,
CONSTRAINT pkuser PRIMARY KEY (idUser)
);
ALTER SEQUENCE user_1_iduser_seq OWNED BY User_1.idUser;
CREATE TABLE userRole (
idUser INTEGER NOT NULL,
roleId INTEGER NOT NULL
);
ALTER TABLE userRole ADD CONSTRAINT role_userrole_fk
FOREIGN KEY (roleId)
REFERENCES Role (roleId)
ON DELETE NO ACTION
ON UPDATE NO ACTION
NOT DEFERRABLE;
ALTER TABLE User_1 ADD CONSTRAINT points_us_fk
FOREIGN KEY (id_points)
REFERENCES Points (idPoints)
ON DELETE CASCADE
ON UPDATE CASCADE
NOT DEFERRABLE;
ALTER TABLE userRole ADD CONSTRAINT user_1_userrole_fk
FOREIGN KEY (idUser)
REFERENCES User_1 (idUser)
ON DELETE NO ACTION
ON UPDATE NO ACTION
NOT DEFERRABLE;
我如何使用数据填充数据库：
INSERT INTO Role VALUES(1, 'ADMIN');
INSERT INTO Role VALUES(2, 'USER');
INSERT INTO Publisher VALUES(1, 'Zielona Sowa');
INSERT INTO Category VALUES(1,'kryminal');
INSERT INTO Points VALUES(1,20);
INSERT INTO Author VALUES(1, 'Tolkien', 'John Ronald Reuel');
INSERT INTO User_1 VALUES(1,1,'oliwka',false,'oliwka@wp.pl','m','o','jakies');
INSERT INTO userRole VALUES(1,1);
INSERT INTO Book VALUES(1,1,1,'Hobbit',null,3,false,1937);
INSERT INTO BooksByAuthors VALUES(1,1,1);
INSERT INTO BooksByCategory VALUES(1,1,1);

答案 0 :(得分：0)
User和Role之间的关联是 多对多 而不是 一对多
在User实体
@ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
@JoinTable(
joinColumns = @JoinColumn(name = "iduser"),
inverseJoinColumns = @JoinColumn(name = "roleid")
)
private Set<Role> roles;
