讲解开始前的准备如下:
一、先新建一个公共的Maven Project项目,项目名称为module-common,参考第一章节步骤创建。
二、右键module-common,在该项目下创建一个Maven Module项目,项目名称为module-common-api。
项目结构图如下:
1)module-common项目下pom.xml配置:
4.0.0
com.maven.xm
module-common
0.0.1-SNAPSHOT
pom
org.springframework.boot
spring-boot-starter-parent
1.5.2.RELEASE
UTF-8
UTF-8
1.8
Camden.SR7
2.7.0
org.springframework.cloud
spring-cloud-dependencies
${spring.cloud.dependencies.version}
pom
import
org.apache.maven.plugins
maven-surefire-plugin
${java.version}
UTF-8
true
central
Central Repository
https://repo.maven.apache.org/maven2
default
false
module-common-api
2)module-common-api项目下pom.xml文件配置:
4.0.0
com.maven.xm
module-common
0.0.1-SNAPSHOT
module-common-api
jar
org.springframework.boot
spring-boot-starter-data-redis
3)module-common-api项目下RedisConfiguration.java文件内容:
注意:该文件为redis操作的主要工具类
package com.maven.xm.redis;
import java.net.UnknownHostException;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
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.core.StringRedisTemplate;
/**
* redis 工具类
* @author ouyangjun
*
*/
@Configuration
public class RedisConfiguration {
@Bean
@ConditionalOnMissingBean(name="redisTemplate")
public RedisTemplate
4)module-common-api项目下RedisStringUtils.java文件内容:
注意:该文件为redis字符操作工具类,其它工具类就不一一展示了,有需要请下载源码观看
package com.maven.xm.redis;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.stereotype.Component;
/**
* redis string操作工具类
* @author ouyangjun
*
*/
@Component
public class RedisStringUtils {
@Autowired
private StringRedisTemplate template;
public void setKey(String key,String value){
ValueOperations ops = template.opsForValue();
ops.set(key,value);
}
public String getValue(String key){
ValueOperations ops = template.opsForValue();
return ops.get(key);
}
}
5)调整module-oauth-resources下pom.xml文件,新增以下内容:
com.maven.xm
module-common-api
0.0.1-SNAPSHOT
6)调整module-oauth-resources下applicaion.properties文件,新增以下内容:
#redis
spring.redis.database = 0
spring.redis.host = 127.0.0.1
spring.redis.port = 6379
spring.redis.password =
spring.redis.encode=UTF-8
spring.redis.timeout = 6000
spring.redis.pool.max-active = 100
spring.redis.pool.max-wait = -1
spring.redis.pool.max-idle = 10
spring.redis.pool.min-idle = 5
7)调整module-oauth-resources下DemoController类,调整之后的代码如下:
package com.maven.xm.oauth.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.maven.xm.redis.RedisStringUtils;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
@Api(tags = "module-oauth模块,用户Demo Controller")
@RestController
@RequestMapping(value = "/demo")
public class DemoController {
@Autowired
private RedisStringUtils redisString;
@ApiOperation(value="module模块,Test方法", notes="Test")
@RequestMapping(value = "/hello", method = RequestMethod.GET)
public String hello(){
// redis操作
redisString.setKey("hello", "Hello Redis!");
return "Hello Demo ouyangjun!";
}
}
8) 依次启动EurekaServerApplication、WebApplication、OAuthApplication模块
注意:启动前,一定要先启动redis-server.exe,否则会访问报错。
在浏览器中输入:http://localhost:8762/xm/demo/ribbon/hello
或
http://localhost:8762/xm/demo/fegin/hello
展示成功界面之后,想判断redis是否已经存在当前的key了,
请参考redis简单命令操作,地址:https://blog.csdn.net/p812438109/article/details/80961169
本章功能已实现完,待续!
