我最近將 Hibernate 從 4.3.7 更新到 5.4.1，并且SchemaExport自 5.1 以來 API 發生了變化。此代碼現在顯示編譯問題（在SchemaExport構造函數和execute方法上）。/** * Method to generate a SQL script which aim is to create SQL tables for the * entities indicated as parameters. */private void generateScript(Class<?>... classes) { Configuration configuration = new Configuration(); configuration.setProperty(Environment.DIALECT, entityManagerFactory.getProperties().get(DIALECT_PROPERTY).toString()); for (Class<?> entityClass : classes) { configuration.addAnnotatedClass(entityClass); } SchemaExport schemaExport = new SchemaExport(configuration); schemaExport.setDelimiter(SCRIPT_DELIMITER); schemaExport.setOutputFile(getScriptPath()); schemaExport.setFormat(true); boolean consolePrint = false; boolean exportInDatabase = false; schemaExport.execute(consolePrint, exportInDatabase, false, true);}我已經看到與此問題相關的其他問題，但沒有足夠具體的內容來幫助我重寫此函數。

這是我所做的并且有效：
private void genererScript(Class<?>... classes) {
StandardServiceRegistry standardRegistry = new StandardServiceRegistryBuilder()
.applySetting(Environment.DIALECT, entityManagerFactory.getProperties().get(DIALECT_PROPERTY).toString())
.build();
MetadataSources sources = new MetadataSources( standardRegistry );
for (Class<?> entityClass : classes) {
sources.addAnnotatedClass(entityClass);
}
MetadataImplementor metadata = (MetadataImplementor) sources
.getMetadataBuilder()
.build();
EnumSet<TargetType> targetTypes = EnumSet.of(TargetType.SCRIPT);
try {
Files.delete(Paths.get(getScriptPath()));
} catch (IOException e) {
/*
* The file did not exist...
* we do nothing.
*/
}
SchemaExport schemaExport = new SchemaExport();
schemaExport.setDelimiter(SCRIPT_DELIMITER);
schemaExport.setOutputFile(getScriptPath());
schemaExport.setFormat(true);
schemaExport.createOnly(targetTypes, metadata);
}
