springmvc整合redis架构搭建实例

2021-07-10 05:57:16

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

第二步:配置文件整合

Web.xml文件配置

</beans>

redis-context.xml内容

Redis.properties文件内容

# Redis settings

第三步:Springmvc对Redis的支持与实例应用.

实例对象

package com.pudp.bae.model;

import com.pudp.bae.base.BaseModel;

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;
    }
    
}

import com.pudp.bae.base.BaseMultiController;
