Spring Boot初次接触记录一下

一、SpringBoot启动入口添加注解

import org.springframework.transaction.annotation.EnableTransactionManagement;

@EnableTransactionManagement
public class App {
  ...
  ...
  ...
}

二、注解事务

/**
 * 中心角色：办理操作
 * @param askComment
 * @return
 */
@ApiOperation(value = "中心角色：办理操作")
@Transactional(rollbackFor=Exception.class) 
@RequestMapping(value = "/dealAsk", method = RequestMethod.PUT, produces = { "application/json" })
public ResponseEntity<?> dealAsk(
    @ApiParam(value = "表单实体数据", required = true) @RequestBody(required = true) GysAskComment askComment){
  ReturnEntity returnEntity = new ReturnEntity();
  int rows1 = -1;
  int rows2 = -1;
  try {
    // 1.修改咨询/投诉状态为“办理中”
    GysAskInfo ask = new GysAskInfo();
    ask.setId(askComment.getAsk_id());
    ask.setStatus(GysAskInfo.CENTER_STATUS_DEALING2);//'办理中'状态
    rows1 = gysAskDAO.updateGysAskStstus(ask);
    // 2.新增回复信息
    rows2 = gysAskDAO.addGysAskReplyInfo(askComment);
  } catch (Exception e) {
    TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();//手动回滚
    e.printStackTrace();
  }
  if (rows1 <= 0 || rows2 <= 0) {
    returnEntity.setCode(ResultCode.FAIL.val());
    returnEntity.setMessage("办理失败");
    return new ResponseEntity<ReturnEntity>(returnEntity, HttpStatus.OK);
  }
  returnEntity.setCode(ResultCode.SUCCESS.val());
  returnEntity.setMessage("办理成功");
  return new ResponseEntity<ReturnEntity>(returnEntity, HttpStatus.OK);
}
