lambda调用方式无法正确映射字段

[zhoujiale]

使用版本
java 17
springboot 3.2.3

  <dependency>
      <groupId>com.github.pagehelper</groupId>
      <artifactId>pagehelper-spring-boot-starter</artifactId>
      <version>2.1.0</version>
  </dependency>
  <dependency>
      <groupId>org.mybatis.dynamic-sql</groupId>
      <artifactId>mybatis-dynamic-sql</artifactId>
      <version>1.5.0</version>
  </dependency>

执行下面两种方式的代码

//lambda
Page<SystemUserVO> page = PageHelper.startPage(systemUserQuery.getPageNum(), systemUserQuery.getPageSize())
                .doSelectPage(() -> systemUserDao.querySystemUserVOList(systemUserQuery));
//非lambda
Page<SystemUserVO> page = PageHelper.startPage(systemUserQuery.getPageNum(), systemUserQuery.getPageSize());
List<SystemUserVO> systemUserVOS = systemUserDao.querySystemUserVOList(systemUserQuery);

dao层方法已经确认将sql中查询的对象转换成java对象返回了，但是使用lambda方式，会将返回的对象转成map而且会使用下划线命名。但是使用非lambda方式就没有这个问题

需要提供更多有关 querySystemUserVOList 的示例代码。

需要提供更多有关 querySystemUserVOList 的示例代码。

private final BaseSelectMapper baseSelectMapper;

 public List<SystemUserVO> querySystemUserVOList(SystemUserQuery systemUserQuery) {
        SelectStatementProvider selectStatementProvider = SelectDSL.select(SYSTEM_USER_VO)
                .from(SystemUserDynamicSqlSupport.systemUser, "su")
                .leftJoin(SystemRoleDynamicSqlSupport.systemRole, "sr")
                .on(SystemUserDynamicSqlSupport.roleId, equalTo(SystemRoleDynamicSqlSupport.id))
                .leftJoin(DepartmentDynamicSqlSupport.department, "d")
                .on(SystemUserDynamicSqlSupport.departmentId, equalTo(DepartmentDynamicSqlSupport.id))
                .where()
                .and(SystemUserDynamicSqlSupport.username, SqlBuilder.isLikeWhenPresent(
                        SQLUtil.like(systemUserQuery.getUsername(), SQLUtil.LikeType.FULL)))
                .and(SystemUserDynamicSqlSupport.realName, SqlBuilder.isLikeWhenPresent(
                        SQLUtil.like(systemUserQuery.getRealName(), SQLUtil.LikeType.FULL)))
                .and(SystemUserDynamicSqlSupport.userStatus, SqlBuilder.isEqualToWhenPresent(systemUserQuery.getUserStatus()))
                .and(SystemUserDynamicSqlSupport.roleId, SqlBuilder.isEqualToWhenPresent(systemUserQuery.getRoleId()))
                .and(SystemUserDynamicSqlSupport.departmentId, SqlBuilder.isEqualToWhenPresent(systemUserQuery.getDepartmentId()))
                .and(SystemUserDynamicSqlSupport.createDate, SqlBuilder.isGreaterThanOrEqualToWhenPresent(systemUserQuery.getStartDate()))
                .and(SystemUserDynamicSqlSupport.createDate, SqlBuilder.isLessThanOrEqualToWhenPresent(systemUserQuery.getEndDate()))
                .and(SystemUserDynamicSqlSupport.isDeleted, SqlBuilder.isEqualTo(false))
                .build().render(RenderingStrategies.MYBATIS3);
        return baseSelectMapper.selectMany(selectStatementProvider,this::mappingSystemUserVO);
    }

import org.mybatis.dynamic.sql.util.mybatis3.CommonSelectMapper;

@Mapper
public interface BaseSelectMapper extends CommonSelectMapper {
}

昨天我自己又debug了下,我看分页插件这里好像会根据resultSetType来映射到java对象，而我这里使用的BaseSelectMapper 继承于CommonSelectMapper ，这个CommonSelectMapper 的resultSetType是java Map。之前写的非lambda方式是因为我自己在dao的方法里面做了对象的映射mappingSystemUserVO方法，所以能成功。不知道推测的对不对
