无法解析名称 org.hibernate.dialect.SQLiteDialect

Question

上周我说“让我们试试 WildFly 10！” 在完成基本配置和 HelloWorld 内容之后，我想看看持久性是如何工作的。A 采用了我的旧 ABC EAR，它有一个 JPA 模块，其中 Hibernate 与 SQLite 一起使用。我设置了net.kemitix提供的方言。

\n\n

因此，我在 POM 文件中设置了它的依赖项：

\n\n

<dependency>\n    <groupId>net.kemitix</groupId>\n    <artifactId>sqlite-dialect</artifactId>\n    <version>0.1.0</version>\n</dependency>\n

\n\n

打包后的 EAR 如下所示：

\n\n

ABC_Ear-0.0.1-SNAPSHOT.ear\n    lib\n        ABC_Jpa-0.0.1-SNAPSHOT.jar\n        sqlite-dialect-0.1.0.jar\n        sqlite-jdbc-3.8.11.2.jar\n

\n\n

持久化.xml：

\n\n

<?xml version="1.0" encoding="UTF-8"?>\n<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">\n    <persistence-unit name="ABC_Jpa" transaction-type="JTA">\n        <class>abc.jpa.User</class>\n        <class>abc.jpa.Group</class>\n        <properties>\n            <property name="javax.persistence.jdbc.url" value="jdbc:sqlite:C:/sqlite/ABC.db"/>\n            <property name="javax.persistence.jdbc.driver" value="org.sqlite.JDBC"/>\n            <property name="jboss.entity.manager.factory.jndi.name" value="java:jboss/AbcEntityManagerFactory" />\n            <property name="jboss.entity.manager.jndi.name" value="java:/AbcEntityManager"/>\n            <property name="hibernate.dialect" value="org.hibernate.dialect.SQLiteDialect"/>\n            <property name="hibernate.show_sql" value="true"/>\n            <property name="hibernate.hbm2ddl.auto" value="create"/> \n        </properties>\n    </persistence-unit>\n</persistence>\n

\n\n

部署过程中出现如下异常：

\n\n

我还尝试将包含方言的 JAR 与驱动程序本身一起加载，但结果相同：

\n\n

C:\\wildfly-10.0.0.Final\\modules\\system\\layers\\base\\org\\xerial\\sqlite-jdbc\\main\\module.xml

\n\n

<module xmlns="urn:jboss:module:1.3" name="org.xerial.sqlite-jdbc">\n    <resources>\n        <resource-root path="sqlite-dialect-0.1.0.jar"/>\n        <resource-root path="sqlite-jdbc-3.8.11.2.jar"/>\n    </resources>\n    <dependencies>\n        <module name="javax.api"/>\n        <module name="javax.transaction.api"/>\n    </dependencies>\n</module>\n

\n\n

有人对这个问题有有效的解决方案吗？同时我将再次重读 WildFly 文档中的相关部分:-)

Answer 1

出错时

无法解析名称 [org.hibernate.dialect.SQLiteDialect]

我通过更改 int application.properties 解决了这个问题：

# for sqlite3
spring.datasource.url=jdbc:sqlite:test_db
spring.datasource.driver-class-name=org.sqlite.JDBC
# old wrond value
#spring.jpa.database-platform=org.hibernate.dialect.SQLiteDialect
# nedd value
spring.jpa.database-platform=org.sqlite.hibernate.dialect.SQLiteDialect

pom.xml 中的此块：

    <dependency>
        <groupId>com.github.gwenn</groupId>
        <artifactId>sqlite-dialect</artifactId>
        <version>0.1.1</version>
    </dependency>
    <dependency>
        <groupId>org.xerial</groupId>
        <artifactId>sqlite-jdbc</artifactId>
        <version>3.30.1</version>
    </dependency>
