Magician-JDBC ·

Magician-JDBC is the official JDBC component of Magician, supporting multiple data sources, no sql single table operations, complex operations can write sql, transaction management, etc.

Creating a data source

// Here is an example using druid, which can actually support any connection pool that implements the DataSource interface
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);

Adding a data source to 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

Single Table Operations

Search by condition

List<Condition> conditionList = ConditionBuilder.createCondition()
            .add("id > ?", 10)
            .add("and (name = ? or age > ?)", "bee", 10))
            .add("order by create_time", Condition.NOT_WHERE))
            .build();

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

Delete by condition

List<Condition> conditionList = ConditionBuilder.createCondition()
        .add("id = ?", 10)
        .build();

JDBCTemplate.get().delete("table name", conditionList);

Insert a piece of data

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

JDBCTemplate.get().insert("table name", demoPO);

Modify data

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

List<Condition> conditionList = ConditionBuilder.createCondition()
        .add("id > ?", 10)
        .add("and name = ?", "bee"))
        .build();

JDBCTemplate.get().update("table name", demoPO, conditionList);

Write your own sql

Select

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);

insert, delete, update

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);

In addition, transaction management and paging are also supported, see the documentation for details
