新换环境,又有新东西可以学习了,哈皮! 抽空学习之余看了一下redis,个人对Springmvc的爱是忠贞不渝,所以整理了一下Springmvc整合redis的环境搭建。分享学习。
第一步: 创建maven项目:
实例pom.xml内容如下

实例对象

public class Member extends BaseModel{
/**

*/
private static final long serialVersionUID = -1959528436584592183L;
private String id;
private String nickname;
public Member(){}
public Member(String id, String nickname){
this.setId(id);
this.setNickname(nickname);
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getNickname() {
return nickname;
}
public void setNickname(String nickname) {
this.nickname = nickname;
}
