有了上面配置后，接下來就可以進行相應的CRUD操作了。
CRUD操作
實體對象?
@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類?
public interface UsersMapper extends BaseMapper<Users> {
}測試類?
@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) ;
}
}
測試結果
數據源及查詢輔助列
在config.yaml文件中我們配置了連接池信息，但是實際沒有生效。如上配置的最小連接數是10，最大是200，但是實際打印都成了默認值都是10。最后修改連接池配置方式如下：?
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
如上配置后連接池才正常。
輔助查詢列會根據你的配置是否使用輔助列，當沒有配置輔助查詢列時，執(zhí)行SQL如下：
使用的是加密列進行查詢了
當配置了輔助查詢列后：
使用的是輔助列查詢。
