休眠程式掛起，沒有任何日志

我正在嘗試使用 hibernate/jpa 從 java 連接到記憶體中的 h2 資料庫，但執行在一段時間后掛起并且不在 DB 中創建任何表或終止。這是我的 persistence.xml 檔案和執行日志

    <?xml version="1.0" encoding="UTF-8" ?>
    
    <persistence xmlns="http://java.sun.com/xml/ns/persistence"
                 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
                          http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
                 version="2.0">
        <persistence-unit name="myApp" transaction-type="RESOURCE_LOCAL">
            <provider> org.hibernate.ejb.HibernatePersistence </provider>
            <properties>
                <property name="javax.persistence.jdbc.url" value="jdbc:h2:tcp://127.0.0.1:8082/~/test"></property>
                <property name="javax.persistence.jdbc.driver" value="org.h2.Driver"></property>
                <property name="javax.persistence.jdbc.user" value="chaitu"></property>
                <property name="javax.persistence.jdbc.password" value=""></property>
                <property name="hibernate.show_sql" value="true"></property>
                <property name="hibernate.format_sql" value="true"></property>
                <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"></property>
                <property name="hibernate.hbm2ddl.auto" value="create-drop"></property>
            </properties>
        </persistence-unit>
    </persistence>

這些是執行日志

參考這個https://www.javatpoint.com/spring-boot-h2-database，你會找到解決方案。首先按照上面提供的鏈接中的說明進行操作并獲得所需的結果，它對我有用。

uj5u.com熱心網友回復：

將您的資料庫 URL 更改為jdbc:h2:mem:test(test是您的資料庫名稱)，因為您使用的是記憶體中的 h2 資料庫并mem代表記憶體中的資料庫。
