springmvc+rest整合redis
最近在做一个项目需要用到关系数据库mysql和缓存redis，以及非关系型数据库mongoDB。昨天下午到今天上午一直在搞springmvc整合redis，期间出现的错误一直让人抓狂，在网上搜索的结果也没有解决得了自己的问题，因此整理此文希望可以帮助到和我一样为整合redis而抓狂的人。
首先，在这里说明springmvc整合redis所需要的jar包，commons-pool-1.6.jar、commons-pool2-2.4.2.jar、jedis-2.9.0.jar、spring-data-commons-1.8.6.RELEASE.jar、spring-data-redis-1.8.6.RELEASE.jar。这里主要用到了这些jar包，期间遇到的jar包冲突问题也是醉醉的了，一直在倒腾jar包，最后终于使用以上几个jar包成功了。
以下用代码告诉大家我是怎么做的
1、redis.properties
redis.ip=127.0.0.1 redis.port=6379 redis.pool.maxActive=100 redis.pool.maxIdle=300 redis.pool.maxWait=1000 redis.pool.testOnBorrow=true
2、redis-config.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" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd" default-autowire="byName" default-lazy-init="true"> <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig"> <property name="maxIdle" value="${redis.pool.maxIdle}" /> <property name="maxTotal" value="${redis.pool.maxActive}" /> <property name="maxWaitMillis" value="${redis.pool.maxWait}" /> <property name="testOnBorrow" value="${redis.pool.testOnBorrow}" /> </bean> <!-- redis服务器中心 --> <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"> <property name="poolConfig" ref="poolConfig" /> <property name="port" value="${redis.port}" /> <property name="hostName" value="${redis.ip}" /> </bean> <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate"> <property name="connectionFactory" ref="connectionFactory" /> <property name="keySerializer"> <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" /> </property> <property name="valueSerializer"> <bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" /> </property> </bean> </beans>
3、applicationContext.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" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:util="http://www.springframework.org/schema/util" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd" default-autowire="byName"> <!-- 启动annotation支持 --> <context:annotation-config /> <context:component-scan base-package="com.fp.daoImpl,com.fp.serviceImpl,com.fp.rest"></context:component-scan> <mvc:annotation-driven/> <!-- <util:properties id="jdbcProps" location="classpath:jdbc.properties"></util:properties> --> <context:property-placeholder location="classpath:jdbc.properties,classpath:redis.properties" /> <!-- 导入redis的配置文件 --> <import resource="redis-config.xml"/> <!-- 配置mysql数据源 --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${jdbc.driverClassName}"/> <property name="url" value="${jdbc.url}"/> <property name="username" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/> </bean> <!-- 配置jdbctemplate，并为其注入dataSource数据源 --> <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"> <property name="dataSource" ref="dataSource"></property> </bean> </beans>
4、jdbc.properties
jdbc.driverClassName=com.mysql.jdbc.Driver jdbc.url = jdbc:mysql://localhost:3306/xxx?useUnicode=true&characterEncoding=utf8 jdbc.username = root jdbc.password =root
5、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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

<!-- 使用rest风格-->
<servlet>
<servlet-name>restService</servlet-name>

</servlet-mapping>
6、模块代码
Member.java
package com.fp.entity; import javax.xml.bind.annotation.XmlRootElement; import com.ems.base.BaseModel; @XmlRootElement 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; } }
MemberDao
package com.fp.dao; import com.fp.entity.Member; public interface MemberDao { Member get(String keyId); }
MemberDaoImpl
package com.fp.daoImpl; import java.io.Serializable; import javax.annotation.Resource; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.dao.DataAccessException; import org.springframework.data.redis.connection.RedisConnection; import org.springframework.data.redis.core.RedisCallback; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.RedisSerializer; import org.springframework.stereotype.Repository; import com.fp.dao.MemberDao; import com.fp.entity.Member; @Repository(value = "memberDao") public class MemberDaoImpl implements MemberDao { @Autowired private RedisTemplate<Serializable, Object> redisTemplate; @Resource public void setRedisTemplate(RedisTemplate<Serializable, Object> redisTemplate) { this.redisTemplate = redisTemplate; } /** * 读取缓存 * * @param key * @return */ public Member get(final String keyId) { Member result = redisTemplate.execute(new RedisCallback<Member>() { public Member doInRedis(RedisConnection connection) throws DataAccessException { RedisSerializer<String> serializer = redisTemplate.getStringSerializer(); byte[] key = serializer.serialize(keyId); byte[] value = connection.get(key); if (value == null) { return null; } String nickname = serializer.deserialize(value); System.out.println("nickname::"+nickname); return new Member(keyId, nickname); } }); return result; } }
MemberService
package com.fp.service; import com.fp.entity.Member; public interface MemberService { public Member get(String id); }
MemberServiceImpl
package com.fp.serviceImpl; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.fp.dao.MemberDao; import com.fp.entity.Member; import com.fp.service.MemberService; @Service("memberService") public class MemberServiceImpl implements MemberService { @Autowired private MemberDao memberDao; public Member get(String id) { return memberDao.get(id); } }
MemberResource(提供rest服务)
package com.fp.rest; import com.fp.entity.Member; import com.fp.service.MemberService; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.PathParam; import javax.ws.rs.Produces; import javax.ws.rs.core.MediaType; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RestController; @RestController @Path("/member") public class MemberResource { @Autowired private MemberService memberService; @Path("/{id}") @GET //表示此服务路径基于get请求模式 @Produces(MediaType.APPLICATION_JSON+";charset=utf-8") //表示响应的结果以文本方式返回 public Member get(@PathParam("id") String id){ return memberService.get(id); } }
7、运行结果
访问地址：http://localhost:8080/JerseyProject/member/id，运行结果如下：
到此springmvc+rest+redis就整合完毕了，重要的事情再强调一遍，一定要导入版本相符的jar包，commons-pool-1.6.jar、commons-pool2-2.4.2.jar、jedis-2.9.0.jar、spring-data-commons-1.8.6.RELEASE.jar、spring-data-redis-1.8.6.RELEASE.jar。相信你一定可以的，嘿嘿。。。
