Java Spring JPA，@JointTable注释不起作用

问题所在：我正在尝试使用Spring安全性实现登录。我正在使用SpringSecurity的默认端点

登录

。我一直收到500，我相信这是由于不正确的接头，因为当我打印

public Set<Role> getRoles() {
    System.out.println("roles");
    System.out.println(roles);
    return roles;
}

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;

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);

堆栈跟踪：

hbm2ddl

自动生成表，以便数据库中的表及其映射准确映射到您的实体。还可以查看完整的映射。我做了此更改，但仍然存在空指针异常。您还有其他建议吗，@AbdullahKhan？您是否自动生成了表？？AFAIK唯一的问题是，如果您现在已经从一个omany更新到多个omany，那么现在的映射就是问题所在。我使用的是
