memcache 问题
今天自己封装memcache批量插入的时候遇到一个问题。当批量插入一个实体对象的时候，插入memcache的value为一个对象时。插入竟然有问题，插入不进去。后来多次查找，多方询问。终于找到了。原来是实体对象没有序列化。把实体对象序列化后插入成功，返回回来一个的value是一个object。
package com.payeco.memcache;
import java.io.Serializable;
import java.sql.Timestamp;
public class StudentDemo implements Serializable{
private static final long serialVersionUID = 8589285238381135252L;
private int id;
private String name;
private String sex;
private int age;
private Timestamp birthday;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public Timestamp getBirthday() {
return birthday;
}
public void setBirthday(Timestamp birthday) {
this.birthday = birthday;
}
@Override
public String toString() {
return String.format("id:%d,name:%s,sex:%s,age:%d,birthday:%s", id,
name, sex, age, birthday);
}
}
后来进行强转之后就没有问题了。
Map<String, Object> mapentity=client.getMulti(li);
for (Map.Entry<String, Object> string : mapentity.entrySet()) {
System.out.println("key-->"+string.getKey());
if (string.getValue() instanceof StudentDemo) {
StudentDemo student=(StudentDemo) string.getValue();
System.out.println(student.getId()+"<--value-->"+student);
}
}
