【参考文章】http://blog.csdn.net/fengyong7723131/article/details/52995592

前言：

redis-cluster实现了缓存分布式和备份，搭建起来特别简单，没搭建的可以看一下redis-cluster集群搭建这篇博客，下面是一些主要的配置文件，如果复制跑不起来的朋友可以直接下载我搞好的完整项目,是一个maven项目，下载地址：http://download.csdn.net/detail/qq_34021712/9822630

Controller层和mapper层接口什么的都不在这里说明了,只是查询一下数据库，直接粘贴serviceImpl类 
package com.redis.service.impl;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.annotation.CacheEvict;
import org.springframework.cache.annotation.CachePut;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.stereotype.Service;


import com.redis.mapper.StudentMapper;
import com.redis.pojo.Student;
import com.redis.service.StudentService;


@Service
public class StudentServiceImpl implements StudentService {

@Autowired
private StudentMapper studentMapper;


@Override
public int insert(Student student) {
System.out.println("插入方法执行了########");
return studentMapper.insert(student);
}


@Override
@CacheEvict(value="defaultCache",key="'student_id_'+#id")
public int deleteByPrimaryKey(Long id) {
System.out.println("删除方法执行了########");
return studentMapper.deleteByPrimaryKey(id);
}


@Override
@CachePut(value="defaultCache",key="'student_id_'+#student.id")
public Student updateByPrimaryKey(Student student) {
System.out.println("修改方法执行了########");
studentMapper.updateByPrimaryKey(student);
return student;
}


@Override
@Cacheable(value="defaultCache",key="'student_id_'+#id")//#id
public Student selectByPrimaryKey(Long id) {
System.out.println("查询方法执行了########");
return studentMapper.selectByPrimaryKey(id);
}


}
