Java Spring引导Redis配置不工作
我正在开发一个带有Java Spring引导Redis配置不工作,java,spring-boot,redis,Java,Spring Boot,Redis,我正在开发一个带有servletializer的springboot[web]REST风格的应用程序(因为它需要部署到现有的Tomcat服务器上)。它有一个@RestController,其方法在调用时需要写入Redis发布子频道。我在本地主机上运行Redis服务器(默认端口,无密码)。POM文件的相关部分具有所需的启动程序依赖项: <dependency> <groupId>org.springframework.boot</groupId>

,其方法在调用时需要写入Redis发布子频道
。我在本地主机上运行Redis服务器(默认端口,无密码)。POM文件的相关部分具有所需的启动程序依赖项:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
我在Spring Boot应用程序类中添加了以下内容:
@Bean
JedisConnectionFactory jedisConnectionFactory() {
return new JedisConnectionFactory();
}
@Bean
public RedisTemplate<String, Object> redisTemplate() {
RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
template.setConnectionFactory(jedisConnectionFactory());
return template;
}
编辑(2017-05-09)
我的理解是,Spring Boot Redis starter假定默认值为Spring.Redis.host=localhost
和Spring.Redis.port=6379
,我仍然将这两个值添加到application.properties
,但这并没有填补空白

我添加了此线程的答案。您需要使用应用程序配置redis服务器信息。属性:
# REDIS (RedisProperties)
spring.redis.cluster.nodes= # Comma-separated list of "host:port"
spring.redis.database=0 # Database index
spring.redis.url= # Connection URL,
spring.redis.host=localhost # Redis server host.
spring.redis.password= # Login password of the redis server.
spring.redis.ssl=false # Enable SSL support.
spring.redis.port=6379 # Redis server port.
Spring数据文档:这是一个与代理相关的问题,甚至连对本地主机的访问都受到了某种程度的限制。一旦我禁用了代理设置,Redis health就启动了!所以问题就解决了。我不必向
应用程序.properties添加任何属性,也不必在Spring Boot应用程序类中显式配置任何内容,因为Spring Boot和Redis Starter会根据Redis默认值自动配置(在我的开发环境中适用)。我刚刚将以下内容添加到pom.xml
:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
要将简单消息发布到频道,这一行代码足以验证设置:
this.redisTemplate.convertAndSend(channelName, "hello world");
我感谢所有的评论,这些评论有助于支持我的支票 我用redis和spring boot做了一个简单的例子
首先,我在docker上安装了redis:
$docker run——说出一些redis-d redis服务器的名称——appendonly yes
然后我将此代码用于接收器:
import java.util.concurrent.CountDownLatch;
public class Receiver {
private static final Logger LOGGER = LoggerFactory.getLogger(Receiver.class);
private CountDownLatch latch;
@Autowired
public Receiver(CountDownLatch latch) {
this.latch = latch;
}
public void receiveMessage(String message) {
LOGGER.info("Received <" + message + ">");
latch.countDown();
}
}
import java.util.concurrent.CountDownLatch;
公共类接收器{
私有静态最终记录器Logger=LoggerFactory.getLogger(Receiver.class);
私人倒计时闩锁;
@自动连线
公用接收器(倒计时闩锁){
this.latch=闩锁;
}
公共无效接收消息(字符串消息){
LOGGER.info(“已收到”);
倒计时();
}
}
这是我的spring boot应用程序和我的侦听器:
@SpringBootApplication
// after add security library then it is need to use security configuration.
@ComponentScan("omid.spring.example.springexample.security")
public class RunSpring {
private static final Logger LOGGER = LoggerFactory.getLogger(RunSpring.class);
public static void main(String[] args) throws InterruptedException {
ConfigurableApplicationContext contex = SpringApplication.run(RunSpring.class, args);
}
@Autowired
private ApplicationContext context;
@RestController
public class SimpleController{
@RequestMapping("/test")
public String getHelloWorld(){
StringRedisTemplate template = context.getBean(StringRedisTemplate.class);
CountDownLatch latch = context.getBean(CountDownLatch.class);
LOGGER.info("Sending message...");
Thread t = new Thread(new Runnable() {
@Override
public void run() {
for (int i = 0 ; i < 100 ; i++) {
template.convertAndSend("chat", i + " => Hello from Redis!");
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
});
t.start();
try {
latch.await();
} catch (InterruptedException e) {
e.printStackTrace();
}
return "hello world 1";
}
}

重要的一点是redis IP。如果你像我一样安装在docker上那么
您应该在application.properties中设置ip地址,如下所示:
spring.redis.host=172.17.0.4
我将所有spring示例都放在github上
此外,我还使用redis stat来监视redis。这是简单的监控。
由于我在本地使用Redis(新安装,没有配置更改),我认为Spring Boot Redis starter采用了这些默认设置。我没有使用集群。唯一适用的Redis属性是spring.Redis.host
(localhost)和spring.Redis.port
(6379)。您的Redis服务正在运行吗。您是否能够通过redis cli连接该服务?您的代码看起来不错…您好@pranestramesh我的redis服务器正在运行。我运行的验证包括telnet localhost 6379
(能够将telnet连接到该端口)和编写基于测试GET的方法
