我尝试过使用这个类:

Hibernate/JPA:在更新DB Schema之前检查生成的sql(如.NET EF迁移)

我有以下代码:

package com.mypackage.jpa.util;

import java.io.File;
import java.net.URL;
import java.util.ArrayList;
import java.util.List;

import org.hibernate.cfg.Configuration;
import org.hibernate.tool.hbm2ddl.SchemaExport;

public class SchemaGenerator {

    private Configuration cfg;

    public static void main(String[] args) throws Exception {

        File f = new File(".");
        String directory = f.getAbsoluteFile() + "/src/main/resources/ddl/generated/";

        String packageName[] = { "com.mypackage.jpa", "com.mypackage.jpa.legacy", "com.mypackage.jpa.local",
                "com.mypackage.jpa.local.impl" };

        SchemaGenerator gen = new SchemaGenerator(packageName);
        gen.generate(Dialect.MYSQL, directory);

    }

    @SuppressWarnings("rawtypes")
    public SchemaGenerator(String[] packagesName) throws Exception {
        cfg = new Configuration();
        cfg.setProperty("hibernate.hbm2ddl.auto", "create");

        for (String packageName : packagesName) …
