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:

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)
