Lỗi khi tạo bean có tên 'entityManagerFactory' được xác định trong tài nguyên đường dẫn lớp: Yêu cầu phương thức init không thành công

Question

Khi tôi biên dịch dự án mùa xuân của mình, có lỗi sau.

Lỗi tạo đậu với tên 'entityManagerFactory' được định nghĩa trong lớp tài nguyên đường [org/Spring Framework/boot/autoconfigure/orm/JPA/HibernateJpaAutoConfiguration.class]: Invocation của phương pháp init thất bại

tôi đang sử dụng STS Eclipse và Cơ sở dữ liệu MySql

chuỗi kết nối của tôi trong Application.Properties là

spring.datasource.url=jdbc:mysql://localhost:3306/stgdb 
spring.datasource.username=root 
spring.datasource.password=root 
spring.datasource.driver-class-name=com.mysql.jdbc.Driver 
spring.jpa.hibernate.ddl-auto=update 

Các lỗi chi tiết được đưa ra dưới đây

Answer 1

Tôi sẽ bắt đầu bằng cách thêm phụ thuộc sau:

<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-core</artifactId> 
    <version>4.1.4.Final</version> 
</dependency> 

và

<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-entitymanager</artifactId> 
    <version>5.2.3.Final</version> 
</dependency> 

Answer 2

<dependency> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-data-jpa</artifactId> 
</dependency> 
<dependency> 
    <groupId>com.h2database</groupId> 
    <artifactId>h2</artifactId> 
</dependency> 

Answer 3

tôi nghi ngờ rằng các tập tin jar của hibernate-core và hibernate-entitymanager phụ thuộc đang bị hỏng hoặc không được cài đặt đúng trên máy tính của bạn.

Tôi khuyên bạn chỉ cần xóa các thư mục có tên hibernate-core và hibernate-entitymanager từ kho lưu trữ cục bộ Maven và Maven sẽ cài đặt lại chúng.

Vị trí mặc định cho Maven kho địa phương là C:\Documents and Settings\[USERNAME]\.m2 trong cửa sổ hoặc /.m2 trong Linux

Answer 4

tôi đã có thể khắc phục vấn đề bằng cách thay đổi giá trị kích thước tối đa bơi từ một đến hai

spring.datasource. hikari.maximum-pool-size = 2
