SpringMVC使用Redis
阿新 • • 發佈：2018-12-12
前置： 1.下載Redis，啟動Redis 2.使用idea內建Maven工具構建SpringMVC專案 參考連結：idea建立SpringMVC專案
本次目標：將物件序列化到Redis中，從Redis中取出。 先單元測試測試Service層，再啟動應用測試Controller層。
- idea建立maven專案。pom檔案如下:
<?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" -
專案結構如下，補充maven未建立的package 在idea中，設定Project structure：java包位置，測試包位置，資源包位置等。

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"

<bean id="jedisConnFactory"

p:host-name="${redis.host}"

<property name="maxTotal" value="${redis.maxActive}"></property>
</bean>
<!--<import resource="classpath:/redis.xml"></import>-->
</beans>
- 配置redis.properties
redis.host=127.0.0.1
#預設埠
redis.port=6379
redis.maxIdle=300
redis.maxActive=600
redis.maxWait=1000
redis.testOnBorrow=true
- 配置dispatcher.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"
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">
<context:component-scan base-package="com.neo.controller"></context:component-scan>
</beans>
- 建立User類
package com.neo.pojo;
import java.io.Serializable;
/**
* @author:neo
*/
public class User implements Serializable {
private String id;
private String username;
private String password;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Override
public String toString(){
return "id:"+id + " username:"+username + " password:"+password;
}
}
- 建立接IUserService介面和實現類
package com.neo.service;
import com.neo.pojo.User;
import java.util.List;
public interface IUserService {
User getUser(String id);
String addUser(User user);
}
package com.neo.service.impl;
import com.neo.pojo.User;
import com.neo.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class UserServiceImpl implements IUserService {
@Autowired
RedisTemplate<String,User> template;
@Override
public String addUser(User user){
ValueOperations<String,User> valueOps = template.opsForValue();
valueOps.set(user.getId(),user);
return "success";
}
@Override
public User getUser(String id){
ValueOperations<String,User> valueOps = template.opsForValue();
User user = valueOps.get(id);
return user;
}
}
- 不啟動tomcat進行Service層的測試。 使用到spring-test，單純只啟動管Service的Spring容器，進行注入。
package com.neo.service;
import com.neo.base.BaseJunit4Test;
import com.neo.pojo.User;
import org.junit.Ignore;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import redis.clients.jedis.Jedis;
import java.io.*;
@RunWith(SpringJUnit4ClassRunner.class) //使用junit4進行測試
@ContextConfiguration(locations={"classpath:applicationContext.xml"}) //載入配置檔案
public class UserServiceTest extends BaseJunit4Test {
@Autowired
private IUserService userService;
@Test
public void testAdd() {
User user = new User();
user.setId("1");
user.setUsername("neo");
user.setPassword("psw");
userService.addUser
