3 配置文件

Spring Boot的配置文件可以配置多个,比如开发环境需要的配置文件、准上线环境需要的配置文件、上线环境需要的配置文件,等等...只需要在主配置文件application.properties中配置spring.profiles.active这个配置项即可动态加载需要的配置文件。以下演示了一个加载开发环境的配置文件application-dev.properties的代码。

3.1 application.properties

spring.profiles.active=dev

3.2 application-dev.properties

#服务器配置
server.port=8080
server.servlet.context-path=/springboot

#日志配置
logging.level.root=info
logging.level.org=warn
logging.level.com.hys.springboot=debug
logging.path=E:/logs

#视图配置
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

#MySQL数据源配置
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/person?serverTimezone=UTC&useSSL=false&allowPublicKeyRetrieval=true&useUnicode=true&characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=root

#MyBatis配置
mybatis.type-aliases-package=com.hys.springboot.entity
mybatis.mapper-locations=classpath:mybatis/mapper/*.xml

#Redis配置
spring.redis.host=192.168.253.129
spring.redis.port=6379

spring.cache.type=none
spring.cache.redis.time-to-live=${random.int[300000,600000]}
spring.cache.redis.key-prefix=com.hys.cache.

#Spring Session配置

spring.rabbitmq.port=5672
spring.rabbitmq.username=root
spring.rabbitmq.password=root
spring.rabbitmq.virtual-host=/

4 Java代码

4.1 启动类

package com.hys.springboot;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration;
import org.springframework.cache.annotation.EnableCaching;

@SpringBootApplication
@MapperScan("com.hys.springboot.dao")
@EnableCaching
@EnableAutoConfiguration(exclude = {SecurityAutoConfiguration.class})
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

上面的自动配置中去掉了SecurityAutoConfiguration类,如果不去掉,则会有一个默认的Spring Security登录页面。

4.2 配置类

4.2.1 Redis配置类

package com.hys.springboot.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

/**
 * Redis配置类
 * @author Robert Hou
 * @date 2019年6月25日
 */
@Configuration
public class RedisConfig {

    /**
     * JSON序列化方式
    * @param redisConnectionFactory RedisConnectionFactory
    * @return RedisTemplate
     */
    @Bean
    public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        return template;
    }
}

默认的RedisTemplate的序列化方式会在Redis中生成的key和value前加上一段元数据的信息,然后拼接上相应的key和value值,对使用者来说并不友好。所以这里使用自定义的序列化方式:将RedisTemplate中的key改用了String的序列化方式,而值则采用了json的序列化方式。

4.2.2 RabbitMQ配置类

package com.hys.springboot.config;

import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.DirectExchange;
import org.springframework.amqp.core.FanoutExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.amqp.core.TopicExchange;
import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;

/**
 * RabbitMQ配置类
 * @author Robert Hou
 * @date 2019年7月1日
 */
@Configuration
public class RabbitMQConfig {

    /**
     * EXCHANGE名称
     */
    public static final String FANOUT_EXCHANGE   = "test.fanout";
    public static final String DIRECT_EXCHANGE   = "test.direct";
    public static final String TOPIC_EXCHANGE    = "test.topic";
    /**

    public static final String FANOUT_QUEUE      = "test.fanout.queue";
    public static final String DIRECT_QUEUE      = "test.direct.queue";
    public static final String TOPIC_QUEUE       = "test.topic.queue";
    /**
     * ROUTINGKEY名称
     */
    public static final String DIRECT_ROUTINGKEY = "direct";
    public static final String TOPIC_ROUTINGKEY  = "topic.#";

    @Bean
    public ConnectionFactory connectionFactory(Environment environment) {
        String addresses = environment.getProperty("spring.rabbitmq.addresses");
        int port = environment.getProperty("spring.rabbitmq.port", Integer.class);
        String username = environment.getProperty("spring.rabbitmq.username");
        String password = environment.getProperty("spring.rabbitmq.password");
        String virtualHost = environment.getProperty("spring.rabbitmq.virtual-host");
        CachingConnectionFactory connectionFactory = new CachingConnectionFactory(addresses, port);
        connectionFactory.setUsername(username);
        connectionFactory.setPassword(password);
        connectionFactory.setVirtualHost(virtualHost);
        connectionFactory.setPublisherConfirms(true);
        return connectionFactory;
    }

    @Bean
    public FanoutExchange fanoutExchange() {
        return new FanoutExchange(FANOUT_EXCHANGE, true, false);
    }

    @Bean
    public DirectExchange directExchange() {
        return new DirectExchange(DIRECT_EXCHANGE, true, false);
    }

    @Bean
    public TopicExchange topicExchange() {
        return new TopicExchange(TOPIC_EXCHANGE, true, false);
    }

    @Bean
    public Queue fanoutQueue() {
        return new Queue(FANOUT_QUEUE, true);
    }

    @Bean
    public Queue directQueue() {
        return new Queue(DIRECT_QUEUE, true);
    }

    @Bean
    public Queue topicQueue() {
        return new Queue(TOPIC_QUEUE, true);
    }

    @Bean
    public Binding fanoutBinding() {
        return BindingBuilder.bind(fanoutQueue()).to(fanoutExchange());
    }

    @Bean
    public Binding directBinding() {
        return BindingBuilder.bind(directQueue()).to(directExchange()).with(DIRECT_ROUTINGKEY);
    }

    @Bean
    public Binding topicBinding() {
        return BindingBuilder.bind(topicQueue()).to(topicExchange()).with(TOPIC_ROUTINGKEY);
    }
}

        Person person1 = (Person) redisTemplate.opsForValue().get("key-0");
    }
}

4.4.3 RabbitMQ

RabbitMQ生产者的接口层和实现层代码如下所示:

package com.hys.springboot.service;

import java.util.Map;

import com.hys.springboot.entity.Order;

public interface IRabbitSenderService {

    void send(String exchange, String routingKey, Object message, Map properties);

    void sendOrder(String exchange, String routingKey, Order order);
}
package com.hys.springboot.service.impl;

import java.util.Map;
import java.util.UUID;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.amqp.rabbit.connection.CorrelationData;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.amqp.rabbit.core.RabbitTemplate.ConfirmCallback;
import org.springframework.amqp.rabbit.core.RabbitTemplate.ReturnCallback;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.messaging.Message;
import org.springframework.messaging.MessageHeaders;
import org.springframework.messaging.support.MessageBuilder;
import org.springframework.stereotype.Service;

import com.hys.springboot.entity.Order;
import com.hys.springboot.service.IRabbitSenderService;

@Service
public class RabbitSenderServiceImpl implements IRabbitSenderService {

    private static final Log      logger           = LogFactory.getLog(RabbitSenderServiceImpl.class);
    @Autowired
    private RabbitTemplate        rabbitTemplate;
    private final ConfirmCallback CONFIRM_CALLBACK = (correlationData, ack, cause) -> {
                                                       if (logger.isDebugEnabled()) {
                                                           logger.debug("correlationData:" + correlationData + " ack:" + ack);
                                                       }
                                                       if (!ack) {
                                                           if (logger.isErrorEnabled()) {
                                                               logger.error("需要异常处理");
                                                           }
                                                       }
                                                   };
    private final ReturnCallback  RETURN_CALLBACK  = (message, replyCode, replyText, exchange, routingKey) -> {
                                                       if (logger.isErrorEnabled()) {
                                                           logger.error("replyCode:" + replyCode + " replyText:" + replyText + " exchange:" + exchange + " routingKey:" + routingKey);
                                                       }
                                                   };

    @Override
    public void send(String exchange, String routingKey, Object message, Map properties) {
        MessageHeaders messageHeaders = new MessageHeaders(properties);
        Message msg = MessageBuilder.createMessage(message, messageHeaders);
        rabbitTemplate.setConfirmCallback(CONFIRM_CALLBACK);
        rabbitTemplate.setReturnCallback(RETURN_CALLBACK);
        CorrelationData correlationData = new CorrelationData();
        correlationData.setId(UUID.randomUUID().toString() + "-" + System.currentTimeMillis());
        rabbitTemplate.convertAndSend(exchange, routingKey, msg, correlationData);
    }

    @Override
    public void sendOrder(String exchange, String routingKey, Order order) {
        rabbitTemplate.setConfirmCallback(CONFIRM_CALLBACK);
        rabbitTemplate.setReturnCallback(RETURN_CALLBACK);
        CorrelationData correlationData = new CorrelationData();
        correlationData.setId(UUID.randomUUID().toString() + "-" + System.currentTimeMillis());
        rabbitTemplate.convertAndSend(exchange, routingKey, order, correlationData);
    }
}
 
  

send方法使用的是默认的Message来发送信息,而sendOrder方法则使用的是Java Bean的方式来发送信息。而相关的生产者测试代码如下所示:

package com.hys.springboot;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import com.hys.springboot.config.RabbitMQConfig;
import com.hys.springboot.entity.Order;
import com.hys.springboot.service.IRabbitSenderService;

@RunWith(SpringRunner.class)
@SpringBootTest
public class ApplicationTests {

    @Autowired
    private IRabbitSenderService rabbitSenderService;

    @Test
    public void testSender1() {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
        Map properties = new HashMap<>();
        properties.put("number", "12345");
        properties.put("send_time", sdf.format(new Date()));
        rabbitSenderService.send(RabbitMQConfig.TOPIC_EXCHANGE, "topic.user", "Hello World", properties);
    }

    @Test
    public void testSender2() {
        Order order = new Order();
        order.setId("001");
        order.setName("订单一");
        rabbitSenderService.sendOrder(RabbitMQConfig.DIRECT_EXCHANGE, RabbitMQConfig.DIRECT_ROUTINGKEY, order);
    }
}

6 运行结果

6.1 页面结果

Spring Boot框架搭建实例_第3张图片

6.2 Redis结果

打开Redis的redis-cli客户端,查看所有的key,结果如下:

Spring Boot框架搭建实例_第4张图片

由上可以看到,不仅存在“key”和“key-0”这样的在service层插入Redis的数据,session数据也一并存入到Redis中。如果在配置文件中将缓存打开并使用Redis的缓存,那么Redis中也会保存相关的缓存数据:

spring.cache.type=redis

6.3 RabbitMQ结果

运行之前的JUnit测试代码,同时保证之前启动的Spring Boot程序没有关闭,在控制台中便可以看到结果:
