spring-boot之一：简单入门
1.在IDE中创建一个web项目
2.在pom.xml文件中增加maven依赖
<parent>
<groupId>org.springframework.bootgroupId>
<artifactId>spring-boot-starter-parentartifactId>
<version>1.5.9.RELEASEversion>
parent>
<dependencies>
<dependency>
<groupId>org.springframework.bootgroupId>
<artifactId>spring-boot-starter-webartifactId>
dependency>
dependencies>
3.创建程序入口类Application.java
package com.xuejia.ad;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* @author kehaojian
* @date 2017-12-28 8:33
* @since 1.0.0
*/
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
4.创建一个controller类
package com.xuejia.ad.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @author kehaojian
* @date 2017-12-28 8:35
* @since 1.0.0
*/
@RestController
public class StartDemoController {
@RequestMapping("/")
String home(){
return "hello";
}
}
5.配置application.yml
server:
port: 8888
tomcat:
uri-encoding: utf-8
spring:
redis:
host: localhost
port: 6379
pool:
max-active: 8
min-idle: 0
max-idle: 8
max-wait: -1
5.运行Application的main方法
6.在浏览器中输入http://localhost:8888/
7.在pom.xml增加spring-boot-starter-redis以及spring-boot-starter-test依赖包
<dependency>
<groupId>org.springframework.bootgroupId>
<artifactId>spring-boot-starter-testartifactId>
dependency>
<dependency>
<groupId>org.springframework.bootgroupId>
<artifactId>spring-boot-starter-redisartifactId>
dependency>
8.创建redis配置类RedisConfig
package com.xuejia.ad.config;
import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import redis.clients.jedis.JedisPoolConfig;
/**
* @author kehaojian
* @date 2017-12-28 9:08
* @since 1.0.0
*/
@Configuration
@ConfigurationProperties(prefix="spring.redis")
public class RedisConfig {
private static Logger logger = LoggerFactory.getLogger(RedisConfig.class);
/*@Bean
public RedisTemplate
StringRedisTemplate template = new StringRedisTemplate(redisConnectionFactory);
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
template.setValueSerializer(jackson2JsonRedisSerializer);
template.afterPropertiesSet();
return template;
}
*/
@Bean
public JedisPoolConfig getRedisConfig(){
JedisPoolConfig config = new JedisPoolConfig();
return config;
}
@Bean
public JedisConnectionFactory getConnectionFactory(){
JedisConnectionFactory factory = new JedisConnectionFactory();
JedisPoolConfig config = getRedisConfig();
factory.setPoolConfig(config);
logger.info("JedisConnectionFactory bean init success.");
return factory;
}
@Bean
public RedisTemplate getRedisTemplate(){
RedisTemplate template = new StringRedisTemplate(getConnectionFactory());
return template;
}
}
9.创建redis简单工具类
package com.xuejia.ad.common;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Repository;
import java.util.concurrent.TimeUnit;
/**
* @author kehaojian
* @date 2017-12-28 9:04
* @since 1.0.0
*/
@Repository
public class RedisUtil {
@Autowired
private RedisTemplate
public void add(String key, String value, Long time){
redisTemplate.opsForValue().set(key, value, time, TimeUnit.SECONDS);
}
public String get(String key) {
return redisTemplate.opsForValue().get(key);
}
public void delete(String key) {
redisTemplate.opsForValue().getOperations().delete(key);
}
}
10.在test目录下创建一个测试类RedisTest
import com.xuejia.ad.common.RedisUtil;
import com.xuejia.ad.config.RedisConfig;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4Cla***unner;
/**
* @author kehaojian
* @date 2017-12-28 9:17
* @since 1.0.0
*/
@RunWith(SpringJUnit4Cla***unner.class)
@ContextConfiguration(classes = {RedisConfig.class, RedisUtil.class})
public class RedisTest {
@Autowired
private RedisUtil redisUtil;
@Before
public void testbefore() {
redisUtil.add("kehaojian", "helloworld", 100L);
}
@Test
public void testRedis() throws InterruptedException {
int total = 20;
for (int i = 0; i < 20; i++){
System.out.println(redisUtil.get("kehaojian"));
Thread.sleep(5000);
}
}
}
11.运行测试类，结果如下
18:57:26.975 [main] DEBUG org.springframework.data.redis.core.RedisConnectionUtils - Opening RedisConnection
18:57:26.975 [main] DEBUG org.springframework.data.redis.core.RedisConnectionUtils - Closing Redis Connection
helloworld
18:57:31.976 [main] DEBUG org.springframework.data.redis.core.RedisConnectionUtils - Opening RedisConnection
18:57:31.976 [main] DEBUG org.springframework.data.redis.core.RedisConnectionUtils - Closing Redis Connection
helloworld
18:57:36.976 [main] DEBUG org.springframework.data.redis.core.RedisConnectionUtils - Opening RedisConnection
18:57:36.976 [main] DEBUG org.springframework.data.redis.core.RedisConnectionUtils - Closing Redis Connection
helloworld
18:57:41.976 [main] DEBUG org.springframework.data.redis.core.RedisConnectionUtils - Opening RedisConnection
18:57:41.976 [main] DEBUG org.springframework.data.redis.core.RedisConnectionUtils - Closing Redis Connection
12.打包，在pom.xml增加打包插件配置
<build>
<plugins>
<plugin>
<groupId>org.springframework.bootgroupId>
<artifactId>spring-boot-maven-pluginartifactId>
<executions>
<execution>
<goals>
<goal>repackagegoal>
goals>
execution>
executions>
plugin>
plugins>
build>
13.执行package操作
