在類路徑資源中定義的名爲'entityManagerFactory'的bean創建時出錯：初始化方法調用失敗

當我編譯我的spring項目時，出現以下錯誤。在類路徑資源中定義的名爲'entityManagerFactory'的bean創建時出錯：初始化方法調用失敗

錯誤創建名稱爲豆 '的entityManagerFactory' 類路徑資源定義 [組織/ springframework的的/ boot /自動配置/ ORM/JPA/HibernateJpaAutoConfiguration.class]：init方法的調用失敗

我使用STS Eclipse和MySQL數據庫

在Application.Properties我的連接字符串是

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

詳細誤差如下

請澄清這一點：Application.Properti應該是application.properties，也表明你的pom.xml。 –

您好，先生，請再檢查我的崗位@ Georgesvanhoutte – thevikasdube

明確了「錯誤」你得竟是「所造成：com.atomikos.jdbc.AtomikosSQLException：連接池耗盡 - 嘗試增加‘maxPoolSize’和/或‘borrowConnectionTimeout’上。 DataSourceBean「。 –

我會從添加以下依賴項開始：

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

和

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

你達人！（這只是爲字符剩下的東西） – cgf

@ georges-van我遇到了同樣的錯誤，你提到的2個依賴已經存在於'spring-boot-starter-data-jpa'中我得到以下錯誤。 https://anotepad.com/notes/wpjr5g –

@ user2493028解決了你的錯誤？ –

我懷疑的hibernate-core和hibernate-entitymanager依賴的jar文件被損壞或沒有你的機器上正確安裝。

我建議你只是從你本地Maven倉庫刪除名爲hibernate-core和hibernate-entitymanager文件夾和Maven會重新安裝它們。

Maven的本地倉庫的默認位置是在Windows C:\Documents and Settings\[USERNAME]\.m2或/.m2在Linux中

我能夠從一個最大池大小值改變兩個

spring.datasource來解決這個問題。 hikari.maximum池大小= 2
