SpringBoot JPA多对一持久化是报错object references an unsaved transient instance

@RequestMapping(value = "/updateRoleOper", method = RequestMethod.POST)@ApiOperation(value = "新增和更新角色操作权限")public ResponseEntity<ResultModel> updateRoleOper(@RequestParam String roleCode, @RequestParam String operId,@RequestParam Integer ifOper,@RequestParam String ctrlCode,@RequestParam String modeCode) {BRole role = roleRepository.findByRoleCode(roleCode);BRoleModeOper roleOper = roleOperRepository.findByRoleCodeAndOperId(roleCode, operId);if (null == roleOper) {roleOper = new BRoleModeOper();roleOper.setRoleCode(roleCode);roleOper.setIfOper(ifOper);roleOper.setOperId(operId);roleOper.setCtrlId(ctrlCode);roleOper.setModeCode(modeCode);} else {roleOper.setIfOper(ifOper);}//多对一保存是需要对一的一方实例化否则会报如下错误//object references an unsaved transient instance - save the transient instance before flushingroleOper.setRole(role);BRoleModeOper saveOper = roleOperRepository.save(roleOper);return new ResponseEntity<>(ResultModel.ok("保存成功"), HttpStatus.OK);}

@ManyToOne(fetch=FetchType.EAGER,optional=true) /*** name  指本表字段名称   referencedColumnName  指关联表字段名称*/@org.hibernate.annotations.ForeignKey(name="none")@JoinColumn(name="role_code", referencedColumnName="role_code",insertable=false,updatable=false)@JsonIgnorepublic BRole getRole() {return role;}
