JOOQ初学-简单的增删改查demo

初学JOOQ，写个blog为了mark一下，也方便大家交流。直接上代码了。在网上搜不到太详细的demo和文档，都是英文的。哎，忧桑、、、在这里写几个demo，大家看看，有不足望指教。

初步的数据库连接，在这里我用了bonecp连接池来管理

import java.sql.Connection;
import java.sql.SQLException;

import org.jooq.DSLContext;
import org.jooq.impl.DSL;

import com.jolbox.bonecp.BoneCP;
import com.jolbox.bonecp.BoneCPConfig;

public class BoneCpPool {

    private static BoneCP boneCp = null;
    private static BoneCPConfig boneCPConfig = null;
    // 静态代码块加载配置文件
    static {
        // 加载JDBC驱动
        try {
            Class.forName("com.mysql.jdbc.Driver");// 注册数据库
            boneCPConfig = new BoneCPConfig();// bonecp数据库连接池配置
            String jdbcUrl = "jdbc:mysql://127.0.0.1:3306/wish";// jdbc:mysql://10.10.0.215:3306/che001
            boneCPConfig.setJdbcUrl(jdbcUrl);
            boneCPConfig.setUser("root");
            boneCPConfig.setPassword("tiger");
            // 数据库连接池的最小连接数
            boneCPConfig.setMinConnectionsPerPartition(5);
            // 数据库连接池的最大连接数
            boneCPConfig.setMaxConnectionsPerPartition(10);
            boneCPConfig.setPartitionCount(1);
            // System.out.println("boneCPConfig"+boneCPConfig);
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
    }

    // 获取连接池
    public static BoneCP getBoneCP() {
        try {
            boneCp = new BoneCP(boneCPConfig);
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return boneCp;
    }

    // 获取连接
    public static Connection getConnection(BoneCP boneCpP) {
        if (boneCpP != null) {
            try {
                return boneCpP.getConnection();
            } catch (SQLException e) {
                return null;
            }
        } else {
            return null;
        }
    }

    // 关闭连接池
    public static void closeBoneCP(BoneCP bc) {
        bc.close();
    }

    // 关闭连接
    public static void closeConnection(Connection con) throws SQLException {
        con.close();
    }

    //
    public static DSLContext getContext(Connection conDsl) {
        return DSL.using(conDsl);
    }
}
