本指南將引導(dǎo)您完成使用Leopard Jdbc操作MySQL。

你可以從頭開始并完成每一個(gè)步驟,或者您可以繞過你已經(jīng)熟悉的基本設(shè)置步驟。無論哪種方式,你最終都可以得到可工作的代碼。

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>

創(chuàng)建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;@Repositorypublic class UserDaoMyqlImpl {@Resourceprivate 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);}}

恭喜你！您已經(jīng)可以在舊項(xiàng)目配置使用Leopard Jdbc，雖然功能比較簡單，你可以在這個(gè)基礎(chǔ)上擴(kuò)展出你的業(yè)務(wù)系統(tǒng)，祝您好運(yùn)。
