Jhipster，Pom配置，延迟加载实体…正在加载所有内容

Question

我有这个模型：您可以将其粘贴到此处https://start.jhipster.tech/jdl-studio/

entity NmsDomain {
  name String required,
  logo ImageBlob,
  brandImg ImageBlob
}


entity NmsTenant {
  name String required,
  image ImageBlob
}


entity NmsZone {
  name String required,
  description String,
  active Boolean,
  lastModifiedDate ZonedDateTime,
  lastModifiedBy String 
}

entity NmsEmployee {
  extensionNumber String,
  photo ImageBlob
}


entity NmsEmployeeLog {
  begin ZonedDateTime,
  end ZonedDateTime,
  deviceType String,
  make String, 
  model String, 
  imei String, 
  serialNumber String, 
  ipAddress String, 
  macAddress String, 
  wifiNetwork String
}

relationship OneToOne {
  NmsEmployee{user(firstName)} to User
  }


  relationship ManyToMany {
  NmsEmployee{possibleZones(name)} to NmsZone{employeePossible}, 
  NmsEmployee{activeZones(name)} to NmsZone{employeeActive}, 
  NmsEmployee{possibleTenants(name)} to NmsTenant{employeePossible}, 
  NmsDomain{user(firstName)} to User{NmsDomain}
}


relationship ManyToOne {
  NmsEmployeeLog{employee} to NmsEmployee, 
  NmsEmployeeLog{zone(name)} to NmsZone, 
  NmsEmployee{domain(name)} to NmsDomain,
  NmsEmployee{tenant(name)} to NmsTenant, 
 NmsTenant{domain(name)} to NmsDomain, 
  NmsZone{tenant(name)} to NmsTenant
}

而且当我在EmployeeLog存储库中进行操作时：

@Query(value ="SELECT entity FROM NmsEmployeeLog entity WHERE entity.employee.id = :empId",
countQuery ="select count(entity) FROM NmsEmployeeLog entity WHERE entity.employee.id = :empId")

Page<NmsEmployeeLog> findByEmpId(@Param("empId") Long empId, Pageable pageable);

在EmployeeLog.java中，我有：

    @ManyToOne(fetch = FetchType.LAZY) 
    @JsonIgnoreProperties("nmsEmployeeLogs")
    private NmsEmployee employee;

    @ManyToOne
    @JsonIgnoreProperties("nmsEmployeeLogs")
    private NmsZone zone;

但是我仍然将所有员工，用户，域，租户信息与很多图像相关联。太慢了...对于员工日志中只有1行，我得到：

          "brandImgContentType": "image/jpeg",
        }
      }
    }
  },
  {
Next Row Log ...

不仅仅是这些字段：

public interface EmployeeLog {
     Long getId();
     ZonedDateTime getBegin();
     ZonedDateTime getEnd();
     String getDevice();
     String getType();
     String getMake();
     String getModel();
     String getImei();
     String getSerialNumber();
     String getIpAddress();
     String getMacAddress();
     String getWifiNetwork();
}

如果我创建一个界面并仅选择这些字段。有用：我什么也没有得到。

但是我需要对大多数实体执行此操作...

是否有一种方法可以指示实体中的延迟加载？

我将此添加到pom.xml并进行./mvn clean compile（我想我已经忘记了）
