springboot整合 rabbitmq

1  添加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

  2 添加配置文件

rabbitmq:
  password: admin
  port: 5672
  host: 139.199.33.78
 username: admin

3 创建配置类  实例化队列  交换机  且绑定

@Configuration
public class SenderConf3 {

    @Bean(name="Amessage")
    public Queue AMessage() {
 return new Queue("fanout.A");
 }


 @Bean(name="Bmessage")
 public Queue BMessage() {
 return new Queue("fanout.B");
 }

 @Bean(name="Cmessage")
 public Queue CMessage() {
 return new Queue("fanout.C");
 }

 @Bean
 FanoutExchange fanoutExchange() {
 return new FanoutExchange("fanoutExchange");//配置广播路由器
 }

 @Bean
 Binding bindingExchangeA(@Qualifier("Amessage") Queue AMessage, FanoutExchange fanoutExchange) {
 return BindingBuilder.bind(AMessage).to(fanoutExchange);
 }

 @Bean
 Binding bindingExchangeB(@Qualifier("Bmessage") Queue BMessage, FanoutExchange fanoutExchange) {
 return BindingBuilder.bind(BMessage).to(fanoutExchange);
 }

 @Bean
 Binding bindingExchangeC(@Qualifier("Cmessage") Queue CMessage, FanoutExchange fanoutExchange) {
 return BindingBuilder.bind(CMessage).to(fanoutExchange);
 }

}


4 创建sender类发送消息

@Component
public class HelloSender {
    @Autowired
    private AmqpTemplate template;

 public void send() {
 template.convertAndSend("queue","hello,rabbit~");
 }

 public void send2(){
 template.convertAndSend("exchange","topic.message","hello,rabbit1");
 }
 public void send3(){
 template.convertAndSend("fanoutExchange","topic.message","hello,rabbit2");
 }

}
5 适当的方法调用sender类 

@RequestMapping("/userLogin")
public String login(HttpSession session, String username, String password, HttpServletRequest request, HttpServletResponse response, Model model) throws Exception {
 List<Userinfo> list = service.findUserByUserName(username);
 if (list.size() > 0 && list != null) {
 Userinfo user = list.get(0);
 if (user.getPassword().equals(MD5Utils.md5(password))) {
 if (user.getUsertype() != Constant.ADMIN) {
 model.addAttribute("info", "权限不足");
 return "login";
 }
 user.setUserstatus(1);
 service.update(user);
 helloSender.send();
 helloSender.send2();
 helloSender.send3();
 session.setAttribute("loginUser", user);
 return "home";
 } else {
 model.addAttribute("info", "用户名或密码错误");
 return "login";
 }
 }
 model.addAttribute("info", "用户名或密码错误");
 return "login";
}
