示例

导入依赖

<dependency>
    <groupId>com.github.yuyenews</groupId>
    <artifactId>Magician-JDBC</artifactId>
    <version>last version</version>
</dependency>

<!-- mysql driver package -->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.20</version>
</dependency>
<!-- druid connection pool -->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>1.2.5</version>
</dependency>

<!-- This is the log package, which supports any package that can be bridged with slf4j -->
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-jdk14</artifactId>
    <version>1.7.12</version>
</dependency>

创建数据源

// 这里用druid做示例，实际上可以支持任意实现了DataSource接口的连接池
DruidDataSource dataSource = new DruidDataSource();

Properties properties = new Properties();
properties.put("druid.name", "local");
properties.put("druid.url", "jdbc:mysql://127.0.0.1:3306/martian-test?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8&autoReconnect=true&rewriteBatchedStatements=true&useSSL=false");
properties.put("druid.username", "root");
properties.put("druid.password", "123456");
properties.put("druid.driverClassName", Driver.class.getName());

dataSource.setConnectProperties(properties);

将数据源添加到JDBC

// Create JDBC, it is recommended to execute it only once when the project starts
MagicianJDBC.createJDBC()
        .addDataSource("a", dataSource)// Add data source, this method can be called multiple times to add multiple data sources
        .defaultDataSourceName("a");// Set the name of the default data source

单表操作

按条件查询

List<Condition> conditionList = new ArrayList<>();
conditionList.add(Condition.get("id > ?", 10));
conditionList.add(Condition.get("and name = ?", 100));
conditionList.add(Condition.get("order by create_time", Condition.NOT_WHERE));

List<Map> result = JDBCTemplate.get().select("表名", conditionList, Map.class);

按条件删除

List<Condition> conditionList = new ArrayList<>();
conditionList.add(Condition.get("id > ?", 10));
conditionList.add(Condition.get("and name = ?", 100));
conditionList.add(Condition.get("order by create_time", Condition.NOT_WHERE));

JDBCTemplate.get().delete("表名", conditionList);

插入一条数据

DemoPO demoPO = new DemoPo();
demoPO.setName("bee");
demoPo.setAge(10);

JDBCTemplate.get().insert("表名", demoPO);

修改数据

DemoPO demoPO = new DemoPo();
demoPO.setName("bee");
demoPo.setAge(10);

List<Condition> conditionList = new ArrayList<>();
conditionList.add(Condition.get("id = ?", 10));
conditionList.add(Condition.get("and name = ?", 100));

JDBCTemplate.get().update("表名", demoPO, conditionList);

自己写sql

查询

DemoPO demoPO = new DemoPo();
demoPO.setName("bee");
demoPo.setAge(10);

List<Map> result = JDBCTemplate.get().selectList("select * from xxx where name={name} and age={age}", demoPO, Map.class);

增删改

DemoPO demoPO = new DemoPo();
demoPO.setName("bee");
demoPo.setAge(10);

JDBCTemplate.get().exec("update xxx set xxx = {xxx}, ccc = {ccc} where name={name} and age={age}", demoPO);

除此之外，还支持事务管理和分页查询，详情可以查看文档
