+
+## 配置数据源
+```properties
+redkale.datasource.platf.url = jdbc:mysql://127.0.0.1:3306/platf?serverTimezone=UTC&characterEncoding=utf8
+redkale.datasource.platf.user = root
+redkale.datasource.platf.password = pwd123
+```
+
+## 增删改
+```java
+@Data
+public class Account {
+    //男
+    public static final short GENDER_MALE = 1;
+
+    //女
+    public static final short GENDER_FEMALE = 2;
+    
+    @Id
+    @Column(name = "account_id")
+    private String accountid;
+
+    @Column(name = "account_name")
+    private String accountName;
+
+    private int age;
+    
+    private short gender;
+
+    private String remark;
+
+    @Column(name = "create_time", updatable = false)
+    private long createTime;
+}
+```
+
+  新增实体对象：
+```java
+    //新增单个
+    Account account = new Account();
+    account.setAccountid("account1");
+    account.setAccountName("Hello");
+    account.setCreateTime(System.currentTimeMillis());
+    source.insert(account);
+
+    //异步新增多个
+    Account a1 = new Account();
+    a1.setAccountid("account1");
+    a1.setAccountName("Hello1");
+    a1.setCreateTime(System.currentTimeMillis());
+    Account a2 = new Account();
+    a2.setAccountid("account2");
+    a2.setAccountName("Hello2");
+    a2.setCreateTime(System.currentTimeMillis());
+    source.insertAsync(a1, a2);
+```
+
+  修改实体对象：
+```java
+    //更新单个字段
+    source.updateColumn(Account.class, "account1", Account::getRemark, "新备注");
+
+    //更新多个字段
+    source.updateColumn(Account.class, "account1",
+        ColumnValue.set(Account::getAccountName, "新名称"),
+        ColumnValue.set(Account::getRemark, "新备注"),
+        ColumnValue.inc(Account::getAge, 2)); //年龄+2
+
+    //更新多个字段
+    Account account = new Account();
+    account.setAccountid("account1");
+    account.setAccountName("新名称");
+    account.setRemark("新备注");
+    source.updateColumn(account, "accountName", "remark");
+    //或者
+    source.updateColumn(account, Account::getAccountName, Account::getRemark);
+
+    //更新整个对象
+    Account one = new Account();
+    one.setAccountid("account1");
+    one.setAccountName("Hello1");
+    one.setCreateTime(System.currentTimeMillis());
+    source.update(one); //createTime不会被更新，因字段设置了@Column(updatable=false)
+
+    //过滤更新
+    source.updateColumn(Account.class, FilterNodes.lt(Account::getAge, 16),
+        ColumnValue.set(Account::getRemark, "不满16岁是青少年"));
+```
+
+  删除实体：
+```java
+    //根据主键值删除
+    Account account = new Account();
+    account.setAccountid("account1");
+    source.delete(account);
+
+    //过滤删除， 删除16以下男生
+    source.delete(Account.class, FilterNodes.lt(Account::getAge, 16).and("gender", GENDER_MALE));
+```
