如何使用jooq而不是xml从表中创建JavaPOJO？

我想使用jooq程序从表中创建.java，而不是通过.xml

我已经尝试过xml，但它不是我想要的

首先，jooq可以做什么

第二，有人知道怎么做吗

import org.jooq.DSLContext;
import org.jooq.Record;
import org.jooq.Result;
import org.jooq.SQLDialect;
import org.jooq.impl.DSL;
import org.jooq.util.DefaultGenerator;
import org.jooq.util.JavaGenerator;
import org.jooq.util.mysql.MySQLDatabase;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class Main {
    public static void main(String[] args) {
        Connection conn = null;

        String userName = "root";
        String password = "root";
        String url = "jdbc:mysql://localhost:3306/library";

        try {
            Class.forName("com.mysql.jdbc.Driver").newInstance();
            conn = DriverManager.getConnection(url, userName, password);

            DSLContext create = DSL.using(conn, SQLDialect.MYSQL);
            Result<Record> result = create.select().from("AUTHOR").fetch();

            //------------ here I want to create AUTHOR.java from table AUTHOR by connecting to database  
            DefaultGenerator  g = new DefaultGenerator();
            MySQLDatabase database = new MySQLDatabase();
            database.getSchema(conn.getSchema());
            JavaGenerator javaGenerator = new JavaGenerator();
            javaGenerator.generate(database);

            //------------

            for (Record r : result) {
                Long id = r.getValue(AUTHOR.ID);
                String firstName = r.getValue(AUTHOR.FIRST_NAME);
                String lastName = r.getValue(AUTHOR.LAST_NAME);

                System.out.println("ID: " + id + " first name: " + firstName + " last name: " + lastName);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (conn != null) {
                try {
                    conn.close();
                } catch (SQLException ignore) {
                }
            }
        }
    }
}

是的，您可以通过编程方式配置jOOQ的代码生成器。当您查看的源代码时，您将看到您可以从控制台调用其重载的main方法，或者通过向其传递org.jooq.util.jaxb.Configuration对象来调用它。例如：

import org.jooq.util.jaxb.*;

// [...]

Configuration configuration = new Configuration()
    .withJdbc(new Jdbc()
        .withDriver("com.mysql.jdbc.Driver")
        .withUrl("jdbc:mysql://localhost:3306/library")
        .withUser("root")
        .withPassword("root"))
    .withGenerator(new Generator()
        .withName("org.jooq.util.DefaultGenerator")
        .withDatabase(new Database()
            .withName("org.jooq.util.mysql.MySQLDatabase")
            .withIncludes(".*")
            .withExcludes("")
            .withInputSchema("library"))
        .withTarget(new Target()
            .withPackageName("org.jooq.util.maven.example")
            .withDirectory("target/generated-sources/jooq")));

GenerationTool.main(configuration);

上面的配置POJO是由XJC生成的，因此您可以使用与XML配置完全相同的结构
