我有一个使用 spring 在经典服务器客户端上工作的项目，但它不适用于休息服务。
在我的 Repo 模块中，我有初始化会话工厂的 Utils 类
package app.repos.db;
import org.hibernate.SessionFactory;
import org.hibernate.boot.MetadataSources;
import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
public class Utils {
protected static SessionFactory sessionFactory;
protected static void initialize() {
// A SessionFactory is set up once for an application!
final StandardServiceRegistry registry = new StandardServiceRegistryBuilder()
.configure() // configures settings from hibernate.cfg.xml
.build();
try {
System.out.println("BEGIN TRY !!");
sessionFactory = new MetadataSources( registry ).buildMetadata().buildSessionFactory();
System.out.println("END TRY !!");
}
catch (Exception e) {
System.err.println("Exception "+e);
e.printStackTrace();
StandardServiceRegistryBuilder.destroy( registry );
}
}
public static void close() {
if (sessionFactory != null) {
sessionFactory.close();
}
}
}
我的 hibernate.cfg.xml 是：
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="dialect">org.hibernate.dialect.SQLiteDialect</property>
<property name="connection.driver_class">org.sqlite.JDBC</property>
<property name="connection.url">jdbc:sqlite:db.sqlite</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<property name="format_sql">true</property>
<mapping resource="domain/jurat.hbm.xml"/>
<mapping resource="domain/participant.hbm.xml"/>
<mapping resource="domain/rezultat.hbm.xml"/>
</session-factory>
</hibernate-configuration>
来自 repos 模块的 gradle：
plugins {
id 'java'
}
group 'org.example'
version '1.0-SNAPSHOT'
sourceCompatibility = 1.8
repositories {
mavenCentral()
}
dependencies {
compile project (':Domain')
testCompile group: 'junit', name: 'junit', version: '4.12'
compile group: 'org.xerial', name: 'sqlite-jdbc', version: '3.20.1'
compile 'javax.xml.bind:jaxb-api:2.3.0'
compile 'javax.activation:activation:1.1'
compile 'org.glassfish.jaxb:jaxb-runtime:2.3.0'
implementation group: 'com.github.gwenn', name: 'sqlite-dialect', version: '0.1.0'
}
我的休息控制器是：
@RestController
@RequestMapping("/app/rezultate")
public class AppController {
@Autowired
private RezultateRepoDB rezultate;
@Autowired
private JuratiRepoDB jurati;
@Autowired
private ParticipantiRepoDB participanti;
@RequestMapping( method=RequestMethod.GET)
public Participant[] getAll(){
return participanti.findAll().toArray(new Participant[0]);
}
}
当我调用 getAll 方法时，我在 Utils 中的 initialize 方法中收到一个错误，我不知道出了什么问题 这是控制台日志

答案 0 :(得分：0)
提供的堆栈跟踪的根本原因：
Caused by: org.hibernate.boot.registry.selector.spi.StrategySelectionException: Unable to resolve name [app.repos.dialect.SQLiteDialect] as strategy [org.hibernate.dialect.Dialect]
请仔细检查您的 SQLiteDialect 类是否扩展了 org.hibernate.dialect.Dialect 并包含有关所有所需映射的数据
或者您可以尝试现有的 SQLiteDialect 而不是使用自定义的：https://mvnrepository.com/artifact/org.hibernate.dialect/sqlite-dialect/0.1.0
