有了上面配置后,接下来就可以进行相应的CRUD操作了。
CRUD操作
实体对象
@TableName("users")
public class Users {
@TableId(type = IdType.ASSIGN_ID)
private Long id;
private String name;
@TableField("id_no")
private String idNo ;
private Integer age;
private String email;
private String pwd ;
}
Mapper类
public interface UsersMapper extends BaseMapper<Users> {
}
测试类
@SpringBootTest
public class UserMapperTest {
@Resource
private UsersMapper usersMapper ;
@Resource
private IUsersService us ;
@Resource
private List<DataSource> dataSources ;
@Test
public void testUserList() {
QueryWrapper<Users> queryWrapper = new QueryWrapper<>() ;
queryWrapper.eq("pwd", "999999") ;
System.out.println(this.usersMapper.selectList(queryWrapper)) ;
}
@Test
public void testSave() {
Users user = new Users() ;
user.setAge(99) ;
user.setEmail("99999@qq.com") ;
user.setIdNo("999999") ;
user.setName("久久") ;
user.setPwd("999999") ;
this.usersMapper.insert(user) ;
}
}
测试结果
数据源及查询辅助列
- 数据源配置
在config.yaml文件中我们配置了连接池信息,但是实际没有生效。如上配置的最小连接数是10,最大是200,但是实际打印都成了默认值都是10。最后修改连接池配置方式如下:
spring:
datasource:
driverClassName: org.apache.shardingsphere.driver.ShardingSphereDriver
url: jdbc:shardingsphere:classpath:config.yaml
name: EncryptHikariCP
hikari:
minimumIdle: 10
maximumPoolSize: 200
autoCommit: true
idleTimeout: 30000
poolName: BaseHikariCP
maxLifetime: 1800000
connectionTimeout: 30000
connectionTestQuery: SELECT 1
如上配置后连接池才正常。
- 辅助查询列
辅助查询列会根据你的配置是否使用辅助列,当没有配置辅助查询列时,执行SQL如下:
使用的是加密列进行查询了
当配置了辅助查询列后:
使用的是辅助列查询。
