springmvc+mybatis+redis實現查詢插入操作


最近在學習redis,雖然現在還不是很熟練。不過可以進行簡單的框架整合開發。

IDE:我使用的是IDEA。springmvc+spring+mybatis的整合這個我就不多說了,下面我們先進行這塊的整合,最后在加入redis。下邊這塊就直接上代碼。

源碼:https://gitee.com/smfx1314/springmvcredis.git

首先看一下我的工程結構:

 

第一步:在pox.xml中引入jar

        </configuration>
      </plugin>

    </plugins>
  </build>
</project>

 

第二步: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"
         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">

  <!-- 配置spring -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!-- 編碼過濾器 -->
  <filter>
    <filter-name>charsetEncodingFilter</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>charsetEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <!-- 配置springmvc -->
  <servlet>
    <servlet-name>springDispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springDispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern><!-- 攔截所有請求 -->
  </servlet-mapping>

</web-app>

 

第三步:配置springmvc.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"
       xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
        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-4.0.xsd">

    <!-- 配置自動掃描的包  -->
    <context:component-scan base-package="com.jiangfx.controller"/>

    <!-- 配置靜態資源文件 -->
    <mvc:default-servlet-handler/>

    <!-- 開啟注解模式 -->
    <mvc:annotation-driven/>
    <!-- 配置視圖解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp"></property><!-- 視圖路徑 -->
        <property name="suffix" value=".jsp"></property><!-- 視圖后綴名 -->
    </bean>
</beans>

 

第四步:配置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:tx="http://www.springframework.org/schema/tx"
       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-4.0.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">

    <!-- 配置掃描的包 -->
    <context:component-scan base-package="com.jiangfx.service"/>

    <!-- 配置數據庫 -->
    <!-- 加載配置文件 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.jdbc.Driver"></property>
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/springredis"></property>
        <property name="user" value="root"></property>
        <property name="password" value="1234"></property>
    </bean>
    <!-- 配置sqlSessionFactory, 並將數據源注入 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 引入數據源 -->
        <property name="dataSource" ref="dataSource"></property>
        <!--載入mybatis配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
        <!--載入配置mapper映射的xml-->
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
    </bean>
    <!-- 配置映射接口 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.jiangfx.mapper"/>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
    </bean>
    <!-- 配置聲明式事務 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    <tx:annotation-driven transaction-manager="transactionManager"/>
</beans>

實體類:entity。一定要實現序列化接口,不然redis沒法對其操作

package com.jiangfx.entity;

import java.io.Serializable;

/**
 * Created by jiangfeixiang on 2018/4/27
 */
public class User implements Serializable {
    private Integer id;
    private String username;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", username='" + username + '\'' +
                '}';
    }
}

 

第五步:Mapper層

編寫UserMapper接口

package com.jiangfx.mapper;

import com.jiangfx.entity.User;

import java.util.List;

/**
 * Created by jiangfeixiang on 2018/4/27
 */
public interface UserMapper {
    /**
     * 查詢
     * @return
     */
    List<User> getAll();

    /**
     * 插入
     * @param user
     */
    void insertUser(User user);
}

之后我們編寫對應的UserMapper.xml

<?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.jiangfx.mapper.UserMapper">

    <!-- 查詢 -->
    <select id="getAll" resultType="User">
        select * from user
    </select>

    <!--插入-->
    <insert id="insertUser" parameterType="User">
        insert into user(id,username) VALUES (#{id},#{username})
    </insert>
</mapper>

 

第六步:service層

首先是UserService接口

package com.jiangfx.service;

import com.jiangfx.entity.User;

import java.util.List;

/**
 * Created by jiangfeixiang on 2018/4/27
 */
public interface UserService {
    /**
     * 查詢
     * @return
     */
    List<User> getAll();

    /**
     * 插入
     */
    void insertUser(User user);
}

然后是對應的實現類

package com.jiangfx.service.Impl;

import com.jiangfx.entity.User;
import com.jiangfx.mapper.UserMapper;
import com.jiangfx.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.annotation.CachePut;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import java.util.List;

/**
 * Created by jiangfeixiang on 2018/4/27
 */
@Service
@Transactional
public class UserServiceImpl implements UserService {
    //注入userMapper
    @Autowired
    private UserMapper userMapper;

    /**
     * 查詢所有
     * 使用@Cacheable地很詭異緩存策略,
     * 當緩存中有值,則返回緩存數據,否則則訪問數據庫
     * value引用緩存管理器,key定義緩存的鍵
     * @return
     */
    @Override
    // @Cacheable(value = "redisCacheManager",key = "'getAll'")
    public List<User> getAll() {
        List<User> userMapperAll = userMapper.getAll();
        System.out.println("沒有走緩存就打印我...........");
        return userMapperAll;
    }

    /**
     * 添加用戶
     */
    @Override
    // @CachePut(value = "redisCacheManager",key = "'insertUser'")
    public void insertUser(User user){
        userMapper.insertUser(user);
    }
}

 

 

第七部:controller層

UserController

package com.jiangfx.controller;

import com.jiangfx.entity.User;
import com.jiangfx.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import java.util.List;

/**
 * Created by jiangfeixiang on 2018/4/27
 */
@Controller
public class UserController {
    //注入
    @Autowired
    private UserService userService;

    /**
     * 查詢所有用戶
     */
    @RequestMapping(value = "/getAll",method = RequestMethod.GET)
    public String getAll(){
        List<User> list = userService.getAll();
        return "list";
    }
    /**
     * 跳轉到添加頁面
     */
    @RequestMapping(value = "/insertUserPage",method = RequestMethod.GET)
    public String insertUserPage(){
        return "save";
    }
    /**
     * 插入
     */
    @RequestMapping(value = "/insertUser",method = RequestMethod.POST)
    public String insertUser(User user){
        userService.insertUser(user);
        return "redirect:/getAll";
    }
}

 

JSP頁面很簡單,主要是為了測試用,一個歡迎頁index.jsp,一個添加用戶頁save.jsp,一個操作成功跳轉對應頁面的list.jsp

 

index.jsp

 <a href="/getAll">查詢</a>
    <a href="/insertUserPage">添加</a>

save.jsp

<form action="/insertUser" method="post">
        姓名:<input type="text" name="username">
        <input type="submit" value="提交">
    </form>

list.jsp我就直接一句話,成功。你們看着寫。

之后啟動測試看看是否成功。當然,如果你安照我的寫,那么肯定不會錯的。

 

接下來我們開始配置redis。

首先加入jar包:

      <!-- jedis -->
      <dependency>
          <groupId>redis.clients</groupId>
          <artifactId>jedis</artifactId>
          <version>2.7.3</version>
      </dependency>
      <!-- spring-data-redis -->
      <dependency>
          <groupId>org.springframework.data</groupId>
          <artifactId>spring-data-redis</artifactId>
          <version>1.6.2.RELEASE</version>
      </dependency>

 

然后:創建一個spring-data-redis.xml專門放置redis的配置,在來一個redis.properties屬性文件,放置redis的屬性配置。如下:

redis.properties

# Redis Setting
# Redis默認有16個庫,序號是0-15,默認是選中的是0號數據庫
spring.redis.database=0  
# Redis服務器地址
spring.redis.host=(你的地址) 
# Redis服務器連接端口,默認是6379
spring.redis.port=6379  
# Redis服務器連接密碼(默認為空)
spring.redis.password=
# 連接池最大阻塞等待時間(使用負值表示沒有限制),根據實際情況修改
spring.redis.pool.maxWaitMillis=-1  
# 連接池中的最大空閑連接,根據實際情況修改
spring.redis.pool.maxIdle=8  
# 連接池中的最小空閑連接,根據實際情況修改
spring.redis.pool.minIdle=0  
# 連接超時時間(毫秒),根據實際情況修改
spring.redis.timeout=2000 

spring-data-redis.xml

 在applicationContext中引入redis的配置spring-data-redis.xml,當然你也可以配置在一起。

    <!-- 引入spring-data-redis.xml -->
    <import resource="spring-data-redis.xml"/>

上面已經定義好緩存管理器了,下面我們就可以在serviceImpl中使用注解進行操作。如下:

在getAll查詢方法上添加(serviceImpl中注釋掉的那點)

 @Cacheable(value = "redisCacheManager",key = "'getAll'")

在insertUser添加方法上加入(serviceImpl中注釋掉的那點)

@CachePut(value = "redisCacheManager",key = "'insertUser'")

注意:

value的值是你redis配置文件對應的緩存管理器的id值
key = "'insertUser'":是你要緩存到redis中的值,下次spring會直接通過key獲取結果。注意key的值中還有個單引號。
@Cacheable:適合查詢,有返回值的方法上。因為,每次請求在進入方法之前,spring會先從緩存服務器中查找對應的key,如果有,就直接返回。否則再去查詢數據庫,在將結果通過key保存到緩存中。
@CachePut:適合添加,修改,void方法上。因為spring不會事先去緩存服務器中查詢數據,而是直接執行方法,然后將結果通過key保存到緩存中。這樣是防止數據不一致。

以上都寫好后可以啟動服務器,然后運行。為了明顯,我在serviceImpl中查詢方法中有個輸出,你可以先注釋掉緩存注解運行,發現每次都會輸入。當你啟動注解時,沒有輸入。說明spring每次回自動到緩存中查找數據。如下:

 

(下面的測試你們可以不用理會,這個是我在搭建環境的時候測試是否搭建成功。我的邏輯可能不夠清晰,有問題可以聯系我)

測試

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.data.redis.core.RedisTemplate;

/**
 * Created by jiangfeixiang on 2018/4/26
 */
public class SpringmvcRedisTest {
    private static ApplicationContext applicationContext;

    static{
        applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
    }

    @Test
    public void testApplicationContext(){
        System.out.println("11111111111111111"+applicationContext);
    }
    @Test
    public void testRedisConnection(){
        RedisTemplate redisTemplate = (RedisTemplate)applicationContext.getBean("redisTemplate");
        redisTemplate.renameIfAbsent("k2", "k1");//如果key=k2存在,則將key修改為k1。前提是你的redis中得有k2。不然報錯。這不你也可以不寫。
        System.out.println(redisTemplate); //這里有輸出也可以。
    }
}

 以上測試這塊,你可以不用寫。

如何查看是否成功?我這里是通過可視化軟件:Redis Desktop Manager,你也可以直接在redis-cli客戶端查看

以上就是springmvc整合redis的過程,如果有什么問題都可以聯系我。
