这几天的研究ssm redis 终于进入主题了，今天参考了网上一些文章搭建了一下ssm+redis整合，特别记录下来以便以后可以查询使用，有什么不足请大牛们提点
项目架构
1、pom.xml

2、jdbc.properties
#JDBCdriver jdbc.driverClassName=oracle.jdbc.driver.OracleDriver #JDBC jdbc.url=你的连接服务器 jdbc.username=数据库账号 jdbc.password=数据库密码 jdbc.publickey=阿里秘钥 jdbc.dbcp.initialSize=10 jdbc.dbcp.maxActive=500 jdbc.dbcp.maxIdle=10 jdbc.dbcp.minIdle=1 jdbc.dbcp.maxWait=120000
3、log4j.properties 可以使用mybatis自带
4、redis.properties
redis.host = 192.168.76.76
redis.port = 6379
redis.pass = admin
redis.maxIdle = 200
redis.maxActive = 1024
redis.maxWait = 10000
redis.testOnBorrow = true

9、User.java
package com.tp.soft.entity; import java.io.Serializable; public class User implements Serializable{ /** * */ private static final long serialVersionUID = -1695973853274402680L; private int userid; private String login_name; private String login_pwd; public User() { } public User(int userid, String login_name, String login_pwd) { super(); this.userid = userid; this.login_name = login_name; this.login_pwd = login_pwd; } public int getUserid() { return userid; } public void setUserid(int userid) { this.userid = userid; } public String getLogin_name() { return login_name; } public void setLogin_name(String login_name) { this.login_name = login_name; } public String getLogin_pwd() { return login_pwd; } public void setLogin_pwd(String login_pwd) { this.login_pwd = login_pwd; } }
10、几个工具类
redisUtil.java 连接池类
package com.tp.soft.redis; import redis.clients.jedis.Jedis; import redis.clients.jedis.JedisPool; import redis.clients.jedis.JedisPoolConfig; public class JedisUtil { private static String ADDR = "192.168.76.76"; private static int PORT = 6379; private static String AUTH = "admin"; private static int MAX_ACTIVE = 1024; private static int MAX_IDLE = 200; private static int MAX_WAIT = 10000; private static int TIMEOUT = 10000; private static boolean TEST_ON_BORROW = true; private static JedisPool jedisPool = null; static { try{ JedisPoolConfig config = new JedisPoolConfig(); config.setMaxIdle(MAX_IDLE); config.setMaxWaitMillis(MAX_WAIT); config.setTestOnBorrow(TEST_ON_BORROW); jedisPool = new JedisPool(config,ADDR,PORT,TIMEOUT,AUTH); }catch (Exception e) { e.printStackTrace(); } } public synchronized static Jedis getJedis(){ try{ if(jedisPool != null){ Jedis jedis = jedisPool.getResource(); return jedis; }else{ return null; } }catch (Exception e) { e.printStackTrace(); return null; } } public static void returnResource(final Jedis jedis){ if(jedis != null){ jedisPool.returnResource(jedis); } } }
SerializeUtil.java 序列化类
package com.tp.soft.redis; import java.io.ByteArrayInputStream; import java.io.ByteArrayOutputStream; import java.io.ObjectInputStream; import java.io.ObjectOutputStream; public class SerializeUtil { public static byte[] serialize(Object object) { ObjectOutputStream oos = null; ByteArrayOutputStream baos = null; try { // 序列化 baos = new ByteArrayOutputStream(); oos = new ObjectOutputStream(baos); oos.writeObject(object); byte[] bytes = baos.toByteArray(); return bytes; } catch (Exception e) { e.printStackTrace(); } return null; } public static Object unserialize(byte[] bytes) { if (bytes == null) return null; ByteArrayInputStream bais = null; try { // 反序列化 bais = new ByteArrayInputStream(bytes); ObjectInputStream ois = new ObjectInputStream(bais); return ois.readObject(); } catch (Exception e) { e.printStackTrace(); } return null; } }
RedisCache.java 缓存类
package com.tp.soft.redis; import java.util.concurrent.locks.ReadWriteLock; import java.util.concurrent.locks.ReentrantReadWriteLock; import org.apache.ibatis.cache.Cache; /* * 使用第三方缓存服务器，处理二级缓存 */ public class RedisCache implements Cache { private final ReadWriteLock readWriteLock = new ReentrantReadWriteLock(); private String id; public RedisCache(final String id) { if (id == null) { throw new IllegalArgumentException("Cache instances require an ID"); } this.id = id; } public String getId() { return this.id; } public void putObject(Object key, Object value) { JedisUtil.getJedis().set(SerializeUtil.serialize(key.toString()), SerializeUtil.serialize(value)); } public Object getObject(Object key) { Object value = SerializeUtil.unserialize(JedisUtil.getJedis().get( SerializeUtil.serialize(key.toString()))); return value; } public Object removeObject(Object key) { return JedisUtil.getJedis().expire( SerializeUtil.serialize(key.toString()), 0); } public void clear() { JedisUtil.getJedis().flushDB(); } public int getSize() { return Integer.valueOf(JedisUtil.getJedis().dbSize().toString()); } public ReadWriteLock getReadWriteLock() { return readWriteLock; } }
11、UserMapper.xml
如果设置useCache="false" 则不进入二级redis缓存
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" > <mapper namespace="com.tp.soft.dao.UserMapper"> <!-- 缓存类配置 --> <cache type="com.tp.soft.redis.RedisCache" /> <select id="getUserById" parameterType="int" resultType="user" useCache="true"> select * from AU_USER where userid = #{id} </select> </mapper>
12、UserMapper.java
package com.tp.soft.dao; import com.tp.soft.entity.User; public interface UserMapper { public User getUserById(int id); }
13、UserSvc.java
package com.tp.soft.service; import com.tp.soft.entity.User; public interface UserSvc { public User getUser(int id); }
14、UserSvcImpl.java
package com.tp.soft.service.impl; import javax.annotation.Resource; import org.springframework.dao.DataAccessException; import org.springframework.stereotype.Service; import com.tp.soft.dao.UserMapper; import com.tp.soft.entity.User; import com.tp.soft.service.UserSvc; @Service("userService") public class UserSvcImpl implements UserSvc{ @Resource private UserMapper userMapper; public User getUser(int id) { User user = null; try{ user = userMapper.getUserById(id); }catch (DataAccessException e) { System.out.println(e.getLocalizedMessage()); } return user; } }
15、配置springmvc
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:util="http://www.springframework.org/schema/util" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:task="http://www.springframework.org/schema/task" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.3.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd"> <!-- 设置注解扫描包 只扫描@Controller注解 --> <context:component-scan base-package="com.tp.soft" use-default-filters="false"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan> <mvc:annotation-driven /> <!-- 静态资源 --> <mvc:default-servlet-handler/> <!-- 默认视图解析器 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:order="3"> <property name="suffix" value=".jsp" /> <property name="prefix" value="/WEB-INF/pages/"></property> </bean> <!-- SpringMVC上传文件时,需配置MultipartResolver处理器 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" p:defaultEncoding="UTF-8"> <!-- 指定所上传文件的总大小不能超过104857600......注意maxUploadSize属性的限制不是针对单个文件,而是所有文件的容量之和 --> <property name="maxUploadSize" value="104857600" /> <property name="maxInMemorySize" value="4096"/> </bean> </beans>
16、配置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/javaee" xmlns:jsp="http://java.sun.com/xml/ns/javaee/jsp" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <display-name>ssm整合(maven)</display-name> <!-- spring配置文件整合配置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring-source.xml, classpath:spring/spring-mybatis.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- springmvc配置 --> <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- druid 监控 --> <servlet> <servlet-name>DruidStatView</servlet-name> <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>DruidStatView</servlet-name> <url-pattern>/druid/*</url-pattern> </servlet-mapping> <filter> <filter-name>druidWebStatFilter</filter-name> <filter-class>com.alibaba.druid.support.http.WebStatFilter</filter-class> <init-param> <param-name>exclusions</param-name> <param-value>/public/*,*.js,*.css,/druid*,*.jsp,*.swf</param-value> </init-param> <init-param> <param-name>principalSessionName</param-name> <param-value>sessionInfo</param-value> </init-param> <init-param> <param-name>profileEnable</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>druidWebStatFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
17、UserController.java
package com.tp.soft.controller; import java.util.HashMap; import java.util.Map; import javax.annotation.Resource; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import com.tp.soft.entity.User; import com.tp.soft.service.UserSvc; @Controller public class UserController { @Resource private UserSvc userSvc; @RequestMapping(value="/toQueryUser") public ModelAndView toQueryUser(){ User user = userSvc.getUser(21); Map<String, Object> map = new HashMap<String, Object>(); map.put("user", user); return new ModelAndView("/pc/userTest", map); } }
18、访问
http://localhost/taop-web-redis/toQueryUser 第一次
结果
访问第二次
结果
不再打印sql
当清空缓存数据
再请求链接
结果
到此 搭建结束，后期将强化项目架构。
