Error while initializing entityManagerFactory in Spring Boot 2 with Hibernate

问题

早上好，
我在启动Spring Boot应用程序时遇到了一个问题，原因是Spring Boot无法自动装配EntityManagerFactory bean。

我已经在这里和网络上查看了各种答案，但没有找到解决方案。

配置如下：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.3.2.RELEASE</version>
    <relativePath/>
</parent>

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

这应该还包含了entityManagerFactory bean的实现，通过查看父pom中的依赖项

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>${hibernate.version}</version>
</dependency>

也存在，所以不应该出现NullPointerException。

我在application.properties文件中配置了Hibernate和数据源，如下：

#与数据源相关的属性
spring.datasource.driver-class-name=org.postgresql.Driver
spring.jpa.database=postgresql
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.hibernate.ddl-auto=none
spring.datasource.url=jdbc:postgresql://localhost:5432/sr002
spring.datasource.username=username
spring.datasource.password=password

主要错误是：

java.lang.IllegalStateException: Failed to asynchronously initialize native EntityManagerFactory: java.lang.ExceptionInInitializerError

和

Caused by: java.lang.ExceptionInInitializerError: null

在代码中，EntityManager 是通过以下方式调用的：

@PersistenceContext
private EntityManager entityManager;

我真的无法理解为什么会出现问题，如果依赖项在父pom中已经写好了。

编辑

通过深入挖掘，我发现AbstractUserTypeHibernateIntegrator.class 中的一个名为jdbc42Apis的参数为空，因此它执行了以下代码行：

JavaVersion.getMajorVersion() >= 1 && JavaVersion.getMinorVersion() >= 8

其中抛出了ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1。有人知道这可能来自哪里吗？在互联网上我没有找到任何信息。

完整的堆栈跟踪如下：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.actuate.autoconfigure.metrics.orm.jpa.HibernateMetricsAutoConfiguration': Injection of autowired dependencies failed; nested exception is java.lang.IllegalStateException: Failed to asynchronously initialize native EntityManagerFactory: java.lang.ExceptionInInitializerError
...
Caused by: java.lang.IllegalStateException: Failed to asynchronously initialize native EntityManagerFactory: java.lang.ExceptionInInitializerError
...
Caused by: java.lang.ExceptionInInitializerError: null
...
Caused by: java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1
...

希望这能帮助您解决问题。

英文:

Good morning,
I am facing a problem in starting a Spring Boot app due to the fact that the EntityManagerFactory bean could not be autowired by Spring boot.

I already looked at various answers here on SO and over the net but didn't find any solution.

The configuration consists in

&lt;parent&gt;
	&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
	&lt;artifactId&gt;spring-boot-starter-parent&lt;/artifactId&gt;
	&lt;version&gt;2.3.2.RELEASE&lt;/version&gt;
	&lt;relativePath/&gt; &lt;!-- lookup parent from repository --&gt;
&lt;/parent&gt;

and

&lt;dependency&gt;
	&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
	&lt;artifactId&gt;spring-boot-starter-data-jpa&lt;/artifactId&gt;
&lt;/dependency&gt;

which should contain also the implementation of the entityManagerFactory bean, by looking in the parent pom the dependency

 &lt;dependency&gt;
    &lt;groupId&gt;org.hibernate&lt;/groupId&gt;
    &lt;artifactId&gt;hibernate-entitymanager&lt;/artifactId&gt;
    &lt;version&gt;${hibernate.version}&lt;/version&gt;
 &lt;/dependency&gt;

is present, so it should not be a NullPointerException.

I Configured Hibernate and the Datasource in the application.properties file with

#Datasource related properties
spring.datasource.driver-class-name=org.postgresql.Driver
spring.jpa.database=postgresql
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.hibernate.ddl-auto=none
spring.datasource.url=jdbc:postgresql://localhost:5432/sr002
spring.datasource.username=username
spring.datasource.password=password

principal errors are

java.lang.IllegalStateException: Failed to asynchronously initialize native EntityManagerFactory: java.lang.ExceptionInInitializerError

and

Caused by: java.lang.ExceptionInInitializerError: null

in the code the Entity Manager is called with:

@PersistenceContext
private EntityManager entityManager;

I can't really figure out why the problem is there if the dependency is written in the parent pom.

EDIT

By digging deeper I found out that a parameter named jdbc42Apis is null in the AbstractUserTypeHibernateIntegrator.class and so it goes to execute a line

JavaVersion.getMajorVersion() &gt;= 1 &amp;&amp; JavaVersion.getMinorVersion() &gt;= 8

where is thrown a ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1. Someone who knows where this could come from? On the internet I didn't manage to find anything.

Full stack trace is

org.springframework.beans.factory.BeanCreationException: Error creating bean with name &#39;org.springframework.boot.actuate.autoconfigure.metrics.orm.jpa.HibernateMetricsAutoConfiguration&#39;: Injection of autowired dependencies failed; nested exception is java.lang.IllegalStateException: Failed to asynchronously initialize native EntityManagerFactory: java.lang.ExceptionInInitializerError

我在使用Java 15的首个版本（docker镜像adoptopenjdk/openjdk15:jdk-15_36-alpine-slim）时遇到了同样的问题。

在 org.jadira.usertype.spi.utils.runtime.JavaVersion 中，Jadira 期望一个包含两个位置的数组：

MAJOR_VERSION = Integer.parseInt(versions[0]);
MINOR_VERSION = Integer.parseInt(versions[1]);

但在那个版本中，它返回的是一个只有一个元素的数组：[15]。

将Java版本升级到15.0.2解决了这个问题（docker镜像adoptopenjdk/openjdk15:jdk-15.0.2_7-alpine-slim）。

英文:

I had the same problem while using the first release of Java 15 (docker image adoptopenjdk/openjdk15:jdk-15_36-alpine-slim).

At org.jadira.usertype.spi.utils.runtime.JavaVersion Jadira is expecting an array with two positions:

MAJOR_VERSION = Integer.parseInt(versions[0]);
MINOR_VERSION = Integer.parseInt(versions[1]);

But in that release it returns an array with only one element: [15].

Upgrading the java version to 15.0.2 solved the problem (docker image adoptopenjdk/openjdk15:jdk-15.0.2_7-alpine-slim)

确保你的Java 17版本类似于 openjdk version "17.0.2"，而不是 jdk-17.jdk。

英文:

For Java 17 make sure your java version is something like openjdk version &quot;17.0.2&quot; and not jdk-17.jdk
