最后我建议大家使用
Spring StringRedisTemplate 配置,参阅:
这次,我们配置一个进阶版本的教程。
功能:1 带有密码
2 分库
先看配置文件以及目录:
spring 文件夹:
applicationContext.xml 总配置文件
spring-business.xml 数据库配置文件(redis也在这里!)
springmvc-servlet.xml spring配置文件
redis.properties 你懂得,redis属性配置
一 redis.properties
# Redis settings
redis.host=192.168.1.88
redis.port=6379
redis.timeOut=10000
# 密码留空很有必要
redis.pass=
redis.maxIdle=300
redis.maxTotal=1024
redis.maxWaitMillis=10000
redis.testOnBorrow=true
# 设置使用的数据库
redis.database=1
redis.pass 密码可以为空,但是必须要写。(这是由于启用分库database的功能,redis的构造函数就需要密码了)
database 选择的数据库(分库)
二 spring-business.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!-- 通常来说,只需要修改initialSize、minIdle、maxActive。 如果用Oracle,则把poolPreparedStatements配置为true,
mysql可以配置为false。分库分表较多的数据库,建议配置为false。 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<!-- 基本属性 url、user、password -->
<property name="url" value="${jdbc.jdbcUrl}"/>
<property name="username" value="${jdbc.user}"/>
<property name="password" value="${jdbc.password}"/>
</bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="configLocation">

</bean>
<bean id="transactionManager"

</bean>
<bean id="transactionTemplate"

</bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

<property name="basePackage" value="com.sanju.sanjuSCM.dao"/>
</bean>
<!-- 启用注解按需添加事务 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
<!--redis配置 -->
<bean name="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
<property name="maxIdle" value="${redis.maxIdle}"/>
<property name="maxTotal" value="${redis.maxTotal}"/>
<property name="maxWaitMillis" value="${redis.maxWaitMillis}"/>

</bean>
<bean name="jedisPool" class="redis.clients.jedis.JedisPool">
<constructor-arg name="poolConfig" ref="jedisPoolConfig"/>
<constructor-arg name="host" value="${redis.host}"/>
<constructor-arg name="port" value="${redis.port}"/>
<constructor-arg name="timeout" value="${redis.timeOut}"/>
<constructor-arg name="password" value="#{'${redis.pass}'!=''?'${redis.pass}':null}"/>
<constructor-arg name="database" value="${redis.database}"/>
</bean>
<bean name="redisHelper" class="com.sanju.sanjuSCM.utils.redisHelper.RedisHelper">
<constructor-arg index="0" ref="jedisPool"/>
</bean>
</beans>
1
这里需要注意的就是:由于我们密码为空,所以这么写
<constructor-arg name="password" value="#{'${redis.pass}'!=''?'${redis.pass}':null}"/>
密码不为空:
<constructor-arg name="password" value="${redis.pass}"/>
2
jedisPoolConfig 和 jedisPool 的配置没什么好说的了,
看一下 redisHelper,这个的class就是RedisHelper的全名+类名。
package com.sanju.sanjuSCM.utils.redisHelper;
import com.sanju.sanjuSCM.model.Token.apiToken;
import com.sanju.sanjuSCM.utils.MD5;
import com.sanju.sanjuSCM.utils.jsonUtil.JsonConvert;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import java.util.Date;
import java.util.Random;
/**
* Created by Tyler on 2017/7/4.
*/
public class RedisHelper {
private JedisPool jedisPool;
private Jedis jedis;
public RedisHelper(){
}
public RedisHelper(JedisPool jedisPool){
this.jedisPool=jedisPool;
this.jedis=this.jedisPool.getResource();
}
}
其中的方法我都删除了,大家可自行添加方法。
三 web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://Java.sun.com/xml/ns/j2ee " xmlns:web="http://xmlns.jcp.org/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee web-app_2_4.xsd"
version="2.4">
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext.xml</param-value>
</context-param>
<servlet>
<servlet-name>sanjuSCM</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/springmvc-servlet.xml</param-value>
</init-param>
<!-- 取消其自动注册的异常解析器 -->
<init-param>
<param-name>detectAllHandlerExceptionResolvers</param-name>
<param-value>false</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
</web-app>
最后看一下调用:
package com.sanju.sanjuSCM.app.controller;
import com.sanju.sanjuSCM.commons.ApiResult;
import com.sanju.sanjuSCM.commons.BaseResult;
import com.sanju.sanjuSCM.model.SysUser;
import com.sanju.sanjuSCM.utils.redisHelper.RedisHelper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@RestController
@RequestMapping("api/test")
public class TestAPIController extends BaseClassAPIController {
@Autowired
RedisHelper redisHelper;
@RequestMapping(value = "test", method = RequestMethod.POST)
public BaseResult test(HttpServletRequest request, HttpServletResponse response, @RequestBody SysUser user) throws Exception {
String p=redisHelper.GetToken("1");
ApiResult rm = new ApiResult();
return rm;
}
}
GetToken是我redisHelper的方法。

我想说,看了网上很多方案,都是拷贝来拷贝去。这一篇是值得一看的。赞一下
