springmvc整合redis架构搭建实例
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
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <packaging>war</packaging> <name>orm-bae</name> <groupId>com.orm</groupId> <artifactId>orm-bae</artifactId> <version>0.0.1-SNAPSHOT</version> <properties> <org.springframework.version>3.0.5.RELEASE</org.springframework.version> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <!-- config junit jar --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.8.2</version> <scope>test</scope> </dependency> <!-- config redis data and client jar--> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-redis</artifactId> <version>1.0.2.RELEASE</version> </dependency> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.1.0</version> </dependency> <!-- config need jar --> <dependency> <groupId>commons-lang</groupId> <artifactId>commons-lang</artifactId> <version>2.6</version> </dependency> <dependency> <groupId>org.apache.geronimo.specs</groupId> <artifactId>geronimo-servlet_3.0_spec</artifactId> <version>1.0</version> </dependency> <!-- cofig spring jar --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc-portlet</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${org.springframework.version}</version> <scope>test</scope> </dependency> </dependencies> <build> <resources> <resource> <directory>/src/main/resources</directory> <filtering>true</filtering> </resource> </resources> </build> </project>
第二步 : 配置文件整合
Web.xml文件配置
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/context/spring-context.xml</param-value> </context-param> <!-- Spring字符集过滤器 --> <filter> <filter-name>SpringEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>SpringEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet> <servlet-name>mvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/context/spring-mvc.xml</param-value> </init-param> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>mvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
spring-context.xml内容
<?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:p="http://www.springframework.org/schema/p" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd"> <!-- 激活@Controller模式 --> <mvc:annotation-driven /> <!-- 对包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 需要更改 --> <context:component-scan base-package="com.pudp.bae.*" /> <!-- 引入同文件夹下的redis属性配置文件 --> <import resource="redis-context.xml"/> </beans>
redis-context.xml内容
<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: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-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd "> <!-- scanner redis properties --> <context:property-placeholder location="/WEB-INF/property/redis.properties" /> <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig"> <property name="maxIdle" value="${redis.maxIdle}" /> <property name="maxActive" value="${redis.maxActive}" /> <property name="maxWait" value="${redis.maxWait}" /> <property name="testOnBorrow" value="${redis.testOnBorrow}" /> </bean> <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" p:host-name="${redis.host}" p:port="${redis.port}" p:password="${redis.pass}" p:pool-config-ref="poolConfig"/> <bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate"> <property name="connectionFactory" ref="connectionFactory" /> </bean> </beans>
Redis.properties文件内容
# Redis settings
#redis.host=192.168.20.101
#redis.port=6380
#redis.pass=foobared
redis.host=127.0.0.1
redis.port=6379
redis.pass=
redis.maxIdle=300
redis.maxActive=600
redis.maxWait=1000
redis.testOnBorrow=true
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; } }

Redis对象持久化操作
package com.pudp.bae.base; import java.io.Serializable; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.RedisSerializer; public abstract class RedisGeneratorDao<K extends Serializable, V extends Serializable> { @Autowired protected RedisTemplate<K,V> redisTemplate ; /** * 设置redisTemplate * @param redisTemplate the redisTemplate to set */ public void setRedisTemplate(RedisTemplate<K, V> redisTemplate) { this.redisTemplate = redisTemplate; } /** * 获取 RedisSerializer * <br>------------------------------<br> */ protected RedisSerializer<String> getRedisSerializer() { return redisTemplate.getStringSerializer(); } }
redis对象操作
package com.pudp.bae.dao.redis; import java.util.ArrayList; import java.util.List; import org.springframework.dao.DataAccessException; import org.springframework.data.redis.connection.RedisConnection; import org.springframework.data.redis.core.RedisCallback; import org.springframework.data.redis.serializer.RedisSerializer; import org.springframework.stereotype.Repository; import org.springframework.util.Assert; import com.pudp.bae.base.RedisGeneratorDao; import com.pudp.bae.model.Member; /** * 参看博客 <br> * ------------------------------------------------------------------------------- * * ------------------------------------------------------------------------------- */ @Repository(value="memberDao") public class MemberDaoImpl extends RedisGeneratorDao<String,Member> implements MemberDao{ /** * 添加对象 */ @Override public boolean add(final Member member) { boolean result = redisTemplate.execute(new RedisCallback<Boolean>() { public Boolean doInRedis(RedisConnection connection) throws DataAccessException { RedisSerializer<String> serializer = getRedisSerializer(); byte[] key = serializer.serialize(member.getId()); byte[] name = serializer.serialize(member.getNickname()); return connection.setNX(key, name); } }); return result; } /** * 添加集合 */ @Override public boolean add(final List<Member> list) { Assert.notEmpty(list); boolean result = redisTemplate.execute(new RedisCallback<Boolean>() { public Boolean doInRedis(RedisConnection connection) throws DataAccessException { RedisSerializer<String> serializer = getRedisSerializer(); for (Member member : list) { byte[] key = serializer.serialize(member.getId()); byte[] name = serializer.serialize(member.getNickname()); connection.setNX(key, name); } return true; } }, false, true); return result; } /** * 删除对象 ,依赖key */ public void delete(String key) { List<String> list = new ArrayList<String>(); list.add(key); delete(list); } /** * 删除集合 ,依赖key集合 */ public void delete(List<String> keys) { redisTemplate.delete(keys); } /** * 修改对象 */ public boolean update(final Member member) { String key = member.getId(); if (get(key) == null) { throw new NullPointerException("数据行不存在, key = " + key); } boolean result = redisTemplate.execute(new RedisCallback<Boolean>() { public Boolean doInRedis(RedisConnection connection) throws DataAccessException { RedisSerializer<String> serializer = getRedisSerializer(); byte[] key = serializer.serialize(member.getId()); byte[] name = serializer.serialize(member.getNickname()); connection.set(key, name); return true; } }); return result; } /** * 根据key获取对象 */ public Member get(final String keyId) { Member result = redisTemplate.execute(new RedisCallback<Member>() { public Member doInRedis(RedisConnection connection) throws DataAccessException { RedisSerializer<String> serializer = getRedisSerializer(); byte[] key = serializer.serialize(keyId); byte[] value = connection.get(key); if (value == null) { return null; } String nickname = serializer.deserialize(value); return new Member(keyId, nickname); } }); return result; } }
Controller实现
package com.pudp.bae.controller; import java.util.HashMap; import java.util.Map; import javax.annotation.Resource; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.ModelAttribute; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.servlet.ModelAndView; import com.pudp.bae.base.BaseMultiController; import com.pudp.bae.model.Member; import com.pudp.bae.service.MemberService; @Controller @RequestMapping(value="/member") public class MemberController extends BaseMultiController{ @Resource(name="memberService") private MemberService memberService; public void setMemberService(MemberService memberService) { this.memberService = memberService; } @RequestMapping(value={"/add","/add.html"},method={RequestMethod.GET}) public ModelAndView add(HttpServletRequest request,HttpServletResponse response){ Map<String,Object> map = new HashMap<String, Object>(); return toView("member/add", map); } @RequestMapping(value={"/add","/add.html"},method={RequestMethod.POST}) public ModelAndView addMember(HttpServletRequest request,HttpServletResponse response, @ModelAttribute("member")Member member){ Map<String,Object> map = new HashMap<String, Object>(); System.out.println(member); map.put("message", "成功添加数据到库," + member); this.memberService.add(member); return toView("member/message", map); } @RequestMapping(value={"/{id:\\d+}/query","/{id:\\d+}/query.html"},method={RequestMethod.GET,RequestMethod.POST}) public ModelAndView queryMember(HttpServletRequest request,HttpServletResponse response, @PathVariable("id")String id){ Map<String,Object> map = new HashMap<String, Object>(); System.out.println(id); Member member = this.memberService.get(id); if(null!=member){ map.put("message", "查询Id=" + id + "的用户名为:" + member.getNickname()); }else{ map.put("message", "没有查询到与Id=" + id + "相关的数据"); } return toView("member/message", map); } @RequestMapping(value={"/{id:\\d+}/delete","/{id:\\d+}/delete.html"},method={RequestMethod.GET,RequestMethod.POST}) public ModelAndView deleteMember(HttpServletRequest request, HttpServletResponse response, @PathVariable("id")String id){ Map<String,Object> map = new HashMap<String, Object>(); try { this.memberService.delete(id); map.put("message", "删除Id为" + id +"的用户成功."); } catch (Exception e) { e.printStackTrace(); map.put("message", "删除Id为" + id +"的用户失败, "+e.getMessage()); } return toView("member/message", map); } }
