我创建了没有Spring Data的示例Gem fire示例。
问题：我的示例工作正常并连接到Gem-fire服务器，并在java代码中返回响应，但是当我在gfsh中运行相同的查询时，则找不到数据
gfsh＆gt; query --query ='select * from / regionA'
结果：是的 startCount：0 endCount：20 行：0
NEXT_STEP_NAME：结束
然后我使用单独的类添加数据并使用单独的类使用获取数据，因此在java代码中返回null。
似乎没有将数据存储到Gem-fire中，任何日志中都没有错误
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
delay(5.0) {
self.sum1TimeLabel?.hidden = false
}
delay(30.0) {
self.sum2TimeLabel?.hidden = false
}
delay(60.0) {
self.sum3TimeLabel?.hidden = false
}
}
func delay(delay:Double, closure:()->()) {
dispatch_after(
dispatch_time(
DISPATCH_TIME_NOW,
Int64(delay * Double(NSEC_PER_SEC))
),
dispatch_get_main_queue(), closure)

从gfsh查询时，您可以尝试在查询中添加投影属性吗？像
这样的东西gfsh>query --query='select name from /regionA'

答案 2 :(得分：0)
我试过DTO的例子
package com.viquar.gem.fire.example;
import static java.lang.System.out;
import java.util.Calendar;
import com.gemstone.gemfire.cache.Region;
import com.gemstone.gemfire.cache.client.ClientCache;
import com.gemstone.gemfire.cache.client.ClientCacheFactory;
public class GemFireDTOExample {
public static void main(final String[] args) {
// final ClientCache cache = new ClientCacheFactory().create();
final ClientCache cache = new ClientCacheFactory().set("cache-xml-file", "gemfiredtoexample.xml").create();
System.out.println("cache-------------------->" + cache);
final Region<Employee, Address> sampleRegion = cache.getRegion("dtoTestRegion");
final Employee emp1 = getEmployee(1L, "shahbaz", 16, 1990);
final Address add1 = getAddress("B-12", "M.G.ROAD", "PUNE");
sampleRegion.put(emp1, add1);
//
final Address sampleValue = sampleRegion.get(emp1);
out.println("------------------------------------------------------" + sampleValue);
// sampleRegion.clear();
cache.close();
}
private static Address getAddress(final String blockName, final String street, final String city) {
final Address add = new Address();
add.setBlockName(blockName);
add.setCity(city);
add.setStreet(street);
return add;
}
private static Employee getEmployee(final Long empId, final String name, final int date, final int year) {
final Employee emp = new Employee();
emp.setEmpId(empId);
emp.setName(name);
final Calendar dateOfBirth = Calendar.getInstance();
dateOfBirth.set(year, Calendar.DECEMBER, date);
emp.setDateOfBirth(dateOfBirth.getTime());
return emp;
}
}
XML：
<!DOCTYPE client-cache PUBLIC
"-//GemStone Systems, Inc.//GemFire Declarative Caching 6.5//EN"
"http://www.gemstone.com/dtd/cache6_5.dtd">
<client-cache>
<pool name="cacheServerPool">

</pool>
<region name="dtoTestRegion" refid="PROXY">

<value-constraint>com.viquar.gem.fire.example.Address</value-constraint>
</region-attributes>
</region>
</client-cache>
然后用DTO创建Jar文件
Address.class Employee.class
现在将jar文件复制到以下路径中：
C:\devprogs\Pivotal_GemFire_800_b48398_Windows\bin\locator1\cluster_config\cluster
现在运行以下命令
gfsh>deploy --jar=C:\devprogs\Pivotal_GemFire_800_b48398_Windows\bin\locator1\cluster_config\cluster\employee_dto.jar
Could not process command due to GemFire error. 'C:\devprogs\Pivotal_GemFire_800_b48398_Windows\bin\locator1\cluster_config\cluster\employee_dto.jar' not found.
gfsh>deploy --jar=C:\devprogs\Pivotal_GemFire_800_b48398_Windows\bin\locator1\cluster_config\cluster\employee_dto.jar

------- | ---------------- | -----------------------------------------------------------------------------------
server1 | employee_dto.jar | C:\devprogs\Pivotal_GemFire_800_b48398_Windows\bin\server1\vf.gf#employee_dto.jar#2
server2 | employee_dto.jar | C:\devprogs\Pivotal_GemFire_800_b48398_Windows\bin\server2\vf.gf#employee_dto.jar#2
gfsh>create region --name=dtoTestRegion --type=REPLICATE --key-constraint=com.viquar.gem.fire.example.Employee --value-constraint=com.viquar.gem.fire.example.Address
Member | Status
------- | --------------------------------------------
server1 | Region "/dtoTestRegion" created on "server1"
server2 | Region "/dtoTestRegion" created on "server2"
现在在gfsh
中执行查询之后运行程序gfsh>query --query='select * from /dtoTestRegion'
Result : true
startCount : 0
endCount : 20
Rows : 1
blockName | city | street
--------- | ---- | --------
B-12 | PUNE | M.G.ROAD
NEXT_STEP_NAME : END
