JPA Hibernate Persistence exception [PersistenceUnit: mặc định] Không thể xây dựng Hibernate SessionFactory

Question

Tôi đã cố gắng sắp xếp kết nối với DB của tôi với JPA Hibernate và mysql, nhưng vì một lý do nào đó, không có vấn đề gì tôi thử, khi khởi chạy tomcat máy chủ tôi nhận được cùng một ngoại lệ:

org.springframework.beans.factory.BeanCreationException: Error creating  bean with name 'localContainerEntityManagerFactoryBean' defined in class path resource [core/JPAConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean]: Factory method 'localContainerEntityManagerFactoryBean' threw exception; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory 

Đây là lớp JPA cấu hình của tôi:

@Configuration 
@EnableJpaRepositories("core.repository") 
@EnableTransactionManagement 
@EnableCaching 
public class JPAConfig { 

@Value("${db.jdbcURL}") 
private String jdbcURL; 

@Value("${db.user}") 
private String user; 

@Value("${db.password}") 
private String password; 

@Value("${db.generateDDL}") 
private Boolean generateDDL; 

@SuppressWarnings("Duplicates") 
@Bean 
public DataSource dataSource() { 
    BasicDataSource dataSource = new BasicDataSource(); 
    dataSource.setDriverClassName(Driver.class.getName()); 
    dataSource.setUrl("jdbc:mysql://localhost:3306/movierentaldb"); 
    dataSource.setUsername(System.getProperty("root")); 
    dataSource.setPassword(System.getProperty("mdie1767")); 
    dataSource.setInitialSize(2); 
    dataSource.setMaxActive(5); 
    return dataSource; 
} 

@Bean 
public LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean(){ 
    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter(); 
    vendorAdapter.setDatabase(Database.MYSQL); 
    vendorAdapter.setGenerateDdl(generateDDL); 
    vendorAdapter.setShowSql(true); 

    LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean(); 

    factory.setJpaVendorAdapter(vendorAdapter); 

    factory.setPackagesToScan("core.model"); 

    factory.setDataSource(dataSource()); 

    factory.afterPropertiesSet(); 
    return factory; 
} 

@Bean 
public EntityManagerFactory entityManagerFactory(){ 
    return localContainerEntityManagerFactoryBean().getObject(); 
} 



@Bean 
public EntityManager entityManager(){ 
    return entityManagerFactory().createEntityManager(); 
} 

@Bean 
PlatformTransactionManager transactionManager(){ 
    JpaTransactionManager manager = new JpaTransactionManager(); 
    manager.setEntityManagerFactory(entityManagerFactory()); 
    return manager; 
} 

@Bean 
public HibernateExceptionTranslator hibernateExceptionTranslator(){ 
    return new HibernateExceptionTranslator(); 
} 

@Bean 
public CacheManager cacheManager(){ 
    GuavaCacheManager guavaCacheManager = new GuavaCacheManager(); 
    guavaCacheManager.setCacheBuilder(CacheBuilder.newBuilder().expireAfterAccess(2, TimeUnit.HOURS)); 
    return guavaCacheManager; 
} 

}

Tại thời điểm này tôi không thể nghĩ ra một nything khác để try..any giúp đỡ được nhiều nghĩa vụ

Edit: Đây là toàn bộ stacktrace

Error:(7, 24) java: package org.gjt.mm.mysql does not exist 

Answer 1

Vấn đề là bạn không thể có được một kết nối đến cơ sở dữ liệu MYSQL và do đó nó được ném một lỗi nói rằng không thể xây dựng một nhà máy phiên.

Xin vui lòng xem các lỗi dưới đây:

Caused by: java.sql.SQLException: Access denied for user ''@'localhost' (using password: NO) 

mà điểm đến username không nhận populated.

Hãy kiểm tra lại hệ thống tính

dataSource.setUsername(System.getProperty("root")); 

một số gói có vẻ là thiếu cũng trỏ đến một vấn đề phụ thuộc:

package org.gjt.mm.mysql does not exist 

hãy chạy một lệnh mvn dependency:tree để kiểm tra phụ thuộc

Answer 2

Tôi đã tìm thấy một số vấn đề về loại lỗi đó

1. Tên người dùng hoặc mật khẩu cơ sở dữ liệu không khớp trong mysql hoặc cơ sở dữ liệu khác. Hãy thiết lập application.properties như

 

# =============================== 
# = DATA SOURCE 
# =============================== 

# Set here configurations for the database connection 

# Connection url for the database please let me know "mondolmislam@gmail.com" 
spring.datasource.url = jdbc:mysql://localhost:3306/bookstoreapiabc 

# Username and secret 
spring.datasource.username = root 
spring.datasource.password = 

# Keep the connection alive if idle for a long time (needed in production) 
spring.datasource.testWhileIdle = true 
spring.datasource.validationQuery = SELECT 1 

# =============================== 
# = JPA/HIBERNATE 
# =============================== 

# Use spring.jpa.properties.* for Hibernate native properties (the prefix is 
# stripped before adding them to the entity manager). 

# Show or not log for each sql query 
spring.jpa.show-sql = true 

# Hibernate ddl auto (create, create-drop, update): with "update" the database 
# schema will be automatically updated accordingly to java entities found in 
# the project 
spring.jpa.hibernate.ddl-auto = update 

# Allows Hibernate to generate SQL optimized for a particular DBMS 
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect 

Issue này không 2.

máy chủ địa phương của bạn có hai máy chủ cơ sở dữ liệu và những xung đột máy chủ cơ sở dữ liệu. xung đột này như thế này máy chủ mysql & xampp hoặc lampp hoặc wamp máy chủ. Xin vui lòng một trong những cơ sở dữ liệu như máy chủ mysql vì xampp hoặc máy chủ lampp tự động cài đặt mysql máy chủ trên máy tính này
