使用Leopard Jdbc

使用Leopard Jdbc

學習如何使用Leopard Jdbc。

本指南將引導您完成使用Leopard Jdbc操做MySQL。

How to complete this guide

你能夠從頭開始並完成每個步驟,或者您能夠繞過你已經熟悉的基本設置步驟。不管哪一種方式,你最終均可以獲得可工做的代碼。

一、配置maven依賴

在dao模塊的pom.xml加入

<dependencies>
        [...]
        <dependency>
            <groupId>io.leopard</groupId>
            <artifactId>leopard-data</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
        [...]
    </dependencies>
    <repositories>
        <repository>
            <id>leopard-snapshots</id>
            <name>Leopard Snapshots</name>
            <url>http://leopard.io/nexus/content/repositories/snapshots/</url>
        </repository>
    </repositories>

二、配置spring

site-dao/src/main/resources/applicationContext-dao.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:leopard="http://www.leopard.io/schema/leopard"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
	http://www.leopard.io/schema/leopard http://www.leopard.io/schema/leopard.xsd">

	<leopard:component-scan base-package="io.leopard.site" />

	<leopard:jdbc id="jdbc" host="112.126.75.27" database="example" user="example" password="leopard" />
	<leopard:redis id="redis" server="112.126.75.27:6311" />

</beans>

三、使用Jdbc接口

建立site-dao/src/main/java/io/leopard/site/dao/mysql/UserDaoMyqlImpl.java

package io.leopard.site.dao.mysql;

import io.leopard.data4j.jdbc.Jdbc;
import io.leopard.data4j.jdbc.builder.InsertBuilder;
import io.leopard.site.model.User;

import javax.annotation.Resource;

import org.springframework.stereotype.Repository;

@Repository
public class UserDaoMyqlImpl {

	@Resource
	private Jdbc jdbc;

	public boolean add(User user) {
		InsertBuilder builder = new InsertBuilder("user");
		builder.setLong("uid", user.getUid());
		builder.setString("passport", user.getPassport());
		builder.setString("nickname", user.getNickname());
		builder.setDate("posttime", user.getPosttime());
		return this.jdbc.insertForBoolean(builder);
	}

	public User get(long uid) {
		String sql = "select * from user where uid=?";
		return this.jdbc.query(sql, User.class);
	}

	public boolean delete(long uid) {
		String sql = "delete from user where uid=?";
		return this.jdbc.updateForBoolean(sql, uid);
	}
}

總結

恭喜你！您已經能夠在舊項目配置使用Leopard Jdbc，雖然功能比較簡單，你能夠在這個基礎上擴展出你的業務系統，祝您好運。
