将对应的包放到任意的磁盘目录
然后进入到目录中:cmd
java -classpath jooq-3.9.5.jar;jooq-meta-3.9.5.jar;jooq-codegen-3.9.5.jar;mysql-connector-java-5.1.14.jar; org.jooq.util.GenerationTool library.xml
对应的测试类:
package com.caisebei.jooq.test;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import org.jooq.DSLContext;
import org.jooq.Record;
import org.jooq.Result;
import org.jooq.SQLDialect;
import org.jooq.impl.DSL;
import com.caisebei.jooq.one.tables.Author;
public class JooqMain {
public static void main(String[] args) {

for (Record r : result) {

String firstName = r.getValue(Author.AUTHOR.FIRST_NAME);
String lastName = r.getValue(Author.AUTHOR.LAST_NAME);
System.out.println("ID: " + id + " first name: " + firstName + " last name: " + lastName);
}
try {
if(conn != null && !conn.isClosed()){
conn.close();
}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static Connection getConnection() {

// 密码
String password = "123456";
// mysql连接url
String url = "jdbc:mysql://localhost:3306/library?useUnicode=true&characterEncoding=UTF-8";

// Connection is the only JDBC resource that we need
// PreparedStatement and ResultSet are handled by jOOQ, internally
try {

System.out.println(conn);
} catch (Exception e) {

}
return conn;

至此,第一次用jooq 写测试demo结束,此后学习会继续更新,相关文档请查看官方英文文档。
