使用STS框架在jdbcTemplate中执行求和操作

Question

我必须使用jdbcTemplate找到sum（actual_effort）和sum（planned_effort），我正在进行下面的编码，但是我得到的是actual_effort和planned_effort的空值，剩下的值正确。请帮帮我......

List<TaskDTO> getAllProjectsTaskReport(){
log.info(" Service getAllProjectsTaskReport");

String sql="select id,sum(actual_effort),actual_end_date,actual_start_date,code,created_date,description,name,sum(planned_effort),planned_end_date,planned_start_date,status,work_completed_percent,assigned_to_id,created_by_id,parent_task_code_id,project_id from task group by project_id";

List<TaskDTO> list  = getJdbcTemplate().query(sql,new BeanPropertyRowMapper(TaskDTO.class));
return list;
}

Answer 1

使用select as

尝试sql

List<TaskDTO> getAllProjectsTaskReport(){
log.info(" Service getAllProjectsTaskReport");

String sql="select id,sum(actual_effort) as actual_effort,actual_end_date,actual_start_date,code,created_date,description,name,sum(planned_effort) as planned_effort,planned_end_date,planned_start_date,status,work_completed_percent,assigned_to_id,created_by_id,parent_task_code_id,project_id from task group by project_id";

List<TaskDTO> list  = getJdbcTemplate().query(sql,new BeanPropertyRowMapper(TaskDTO.class));
return list;
}
