Spring Boot JPA Hibernate： 'entityManagerFactory'という名前のBeanの作成エラー

私は、MySQLデータベースに格納されているユーザーを認証するためにSpringBoot Securityを使用するSpring Bootアプリケーションをセットアップしようとしています。私はこれを行う方法についていくつかのチュートリアルに従ってきましたが、mavenでアプリケーションを実行しようとすると、次のエラーが発生します：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

私が間違っていない場合、これはデータベースに接続できないことを意味しているため、bean entityManagerFactoryの作成に問題があります。

だから、これは私のpom.xmlファイルです

次に、次の2つのエンティティを定義しました。

ser.Java

package com.proba.Userboard.entity;

import Java.util.Set;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.Table;

@Entity
@Table(name="user")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name="user_id")
    private int id;
    @Column(name="username")
    private String username;
    @Column(name="pass")
    private String pass;
    @Column(name="name")
    private String name;
    private String passConfirm;
    private Set<Role> roles;

    public User() {

    }
    public User(String usr, String pas, String nam) {
        this.username = usr;
        this.pass = pas;
        this.name = nam;
    }
    @Override
    public String toString() {
        return String.format("{ id : %d, username : %s, pass : %s, name : %s }", this.id, this.username, this.pass, this.name);
    }
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPass() {
        return pass;
    }
    public void setPass(String pass) {
        this.pass = pass;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    @ManyToMany
    @JoinTable(name="user_role", joinColumns = @JoinColumn(name="user_id"), inverseJoinColumns = @JoinColumn(name="role_id"))
    public Set<Role> getRoles() {
        return roles;
    }
    public void setRoles(Set<Role> roles) {
        this.roles = roles;
    }
    public String getPassConfirm() {
        return passConfirm;
    }
    public void setPassConfirm(String passConfirm) {
        this.passConfirm = passConfirm;
    }
}

Role.Java

package com.proba.Userboard.entity;

import Java.util.Set;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.ManyToMany;
import javax.persistence.Table;

@Entity
@Table(name="role")
public class Role {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name="role")
    private int id;
    @Column(name="role_name")
    private String name;
    private Set<User> users;

    public Role() {

    }
    public Role(String n) {
        this.name = n;
    }
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    @ManyToMany(mappedBy = "roles")
    public Set<User> getUsers() {
        return users;
    }
    public void setUsers(Set<User> users) {
        this.users = users;
    }
    @Override
    public String toString() {
        return String.format("{ id : %s, name: %s }", this.id, this.name);
    }
}

次のDAOがあります。

RoleDAO.Java

package com.proba.Userboard.dao;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import com.proba.Userboard.entity.Role;

@Repository
@Transactional
public interface RoleDAO extends JpaRepository<Role, Integer> {

}

serDAO.Java

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import com.proba.Userboard.entity.User;

@Repository
@Transactional
public interface UserDAO extends JpaRepository<User, Integer> {
    public User findByUsername(String username);
}

私ユーザーサービス：

package com.proba.Userboard.service;

import Java.util.HashSet;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import com.proba.Userboard.dao.RoleDAO;
import com.proba.Userboard.dao.UserDAO;
import com.proba.Userboard.entity.User;

public class UserServiceImpl implements UserService {
    @Autowired
    private UserDAO userDAO;
    @Autowired
    private RoleDAO roleDAO;
    @Autowired
    private BCryptPasswordEncoder bcrypt;

    @Override
    public void save(User user) {

        user.setPass(bcrypt.encode(user.getPass()));
        user.setRoles(new HashSet<>(roleDAO.findAll()));
        userDAO.save(user);

    }
    @Override
    public User findByUsername(String username) {
        return userDAO.findByUsername(username);
    }
}

私SpringBootセキュリティ構成：

package com.proba.Userboard.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

@Configuration
@EnableWebSecurity
public class SecurityConf extends WebSecurityConfigurerAdapter {
    @Autowired
    private UserDetailsService userDetailsService;
    @Bean
    public BCryptPasswordEncoder bcyrpt() {
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/resource/**", "/registration").permitAll()
                .anyRequest().authenticated()
            .and()
                .formLogin()
                    .loginPage("/login")
                    .permitAll()
            .and()
                .logout()
                    .permitAll();
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(bcyrpt());
    }
}

したがって、mvn clean spring-boot：runを実行すると、前述のエラーが発生し、何が間違っているのか理解できません。以前、私は同様のアプリを作成しましたが、うまくいきましたが、なぜこれがうまくいかないのかわかりません。

いいえ、問題はデータベースの接続ではありません。 Hibernateは、ID（属性自体またはメソッド）の注釈の場所に基づいて構成注釈をチェックするポリシーを決定します。

Userクラスでは、属性レベルの注釈を期待するようにhibernateに指示しています。

public class User {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name="user_id")
private int id;

したがって、Hibernateの場合、マッピングのメソッドをチェックしないため、ロールなどの他の属性のマッピングはありません。そのため、メソッドからアノテーションを取得して属性に配置する必要があります。

@ManyToMany
@JoinTable(name="user_role", joinColumns = @JoinColumn(name="user_id"), inverseJoinColumns = @JoinColumn(name="role_id"))
private Set<Role> roles;

すべての注釈でこれを行う必要があります。

上記の例外と一緒にマッピング例外がある場合、問題はJdk 11とjavassistにある可能性があります。

これをpom.xmlに追加する必要があります

<dependency>
    <groupId>org.javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.23.1-GA</version>
</dependency>
