Question

我最近在youtube上完成了Hibernate + Spring Data JPA教程，但是作者没有在视频中显示persistence.xml文件中应该包含的内容。这是我的pom.xml：

<?xml version="1.0" encoding="UTF-8"?>

http://maven.apache.org/xsd/maven-4.0.0.xsd"> 4.0.0

<groupId>Hibernate_Spring</groupId>
<artifactId>Hibernate_Spring</artifactId>
<version>1.0-SNAPSHOT</version>
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
</build>


<dependencies><!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>6.0.6</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-core -->
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>

    </dependency>
    <!-- https://mvnrepository.com/artifact/org.springframework.data/spring-data-jpa -->
    <dependency>
        <groupId>org.springframework.data</groupId>

    </dependency>
    <!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-api -->

        <artifactId>slf4j-simple</artifactId>
        <version>1.6.1</version>
    </dependency>


</dependencies>

这是我的applicationContext.xml：

<bean id="dataSource"
      class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName">
        <value>com.mysql.cj.jdbc.Driver</value>
    </property>
    <property name="url">
        <value>jdbc:mysql://localhost:3306/test2?useUnicode=true&amp;useJDBCCompliantTimezoneShift=true&amp;useLegacyDatetimeCode=false&amp;serverTimezone=UTC&amp;useSSL=false</value>
    </property>
    <property name="username">
        <value>root</value>
    </property>
    <property name="password">
        <value>root</value>
    </property>
</bean>

<bean id="entityManagerFactory"
      class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="persistenceUnitName" value="jpaData" />
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
    </property>
    <property name="jpaProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.format_sql">false</prop>
            <prop key="hibernate.hbm2ddl.auto">create</prop>
        </props>
    </property>
</bean>

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

你能帮我解决这个问题吗？

Answer 1

你有persitence.xml文件吗？你能表现出来吗？

也许你应该在没有<property name="persistenceUnitName" value="jpaData" />

的情况下尝试

java.lang.IllegalArgumentException：没有名称为＆＃39; jpaData＆＃39;的持久性单元发现
