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 {@Resourceprivate UsersMapper usersMapper ;@Resourceprivate IUsersService us ;@Resourceprivate List<DataSource> dataSources ;@Testpublic void testUserList() {QueryWrapper<Users> queryWrapper = new QueryWrapper<>() ;queryWrapper.eq("pwd", "999999") ;System.out.println(this.usersMapper.selectList(queryWrapper)) ;}@Testpublic 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.yamlname: EncryptHikariCPhikari:minimumIdle: 10maximumPoolSize: 200autoCommit: trueidleTimeout: 30000poolName: BaseHikariCPmaxLifetime: 1800000connectionTimeout: 30000connectionTestQuery: SELECT 1

如上配置后连接池才正常。
