Spring boot 集成 nacos、redis、mysql

article 2024/11/17 2:16:24

1，准备好nacos环境，准备ncc.yml配置：

在配置添加

test: haha

2，添加依赖

在pom.xml 文件中添加Nacos 客户端的依赖，样例使用Spring Cloud Alibaba

版本使用2023.x 分支，详情可查看

版本发布说明-阿里云Spring Cloud Alibaba官网

  <dependencies>

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

    <dependency>
      <groupId>com.alibaba.cloud</groupId>
      <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
    </dependency>

  </dependencies>

 
<!--新增依赖集中管理-->
  <dependencyManagement>
    <dependencies>
      <!--spring-boot-->
      <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>3.2.4</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>
      <!--spring-cloud-->
      <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-dependencies</artifactId>
        <version>2023.0.1</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>
      <!--spring-alibaba-->
      <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-alibaba-dependencies</artifactId>
        <version>2023.0.1.3</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>
    </dependencies>
  </dependencyManagement>

3，配置application.yml

spring:
  cloud:
    nacos:
      serverAddr: 127.0.0.1:8848
      username: nacos
      password: nacos@2024
      namespace: ncc
      group: dev
      config:
        file-extension: yaml
  config:
    import:
      - nacos:ncc.yml?refreshEnabled=true

4，配置启动类 NccApplication

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class NccApplication {

	@Value("${test}")
	private String test;

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

	@GetMapping("/test")
	public String test() {
		return test;
	}

}

5，启动测试：

本地访问

http://localhost:8080/test

6，添加redis

pom.xml增加redis依赖

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

在ncc.yml配置添加redis

spring:
  data:
    redis:
      host: 47.108.195.11
      port: 6379
      password: redis@2024
      database: 0

增加test依赖

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

创建测试类测试RedisTest

import java.util.concurrent.TimeUnit;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.StringRedisTemplate;

@SpringBootTest(classes = NccApplication.class)
public class RedisTest {

    @Autowired
    private StringRedisTemplate stringRedisTemplate;

    String redisKey="demo";

    @Test
    void redisTest() {
        stringRedisTemplate.opsForValue().set(redisKey,"test1",10, TimeUnit.MINUTES);
        String val = stringRedisTemplate.opsForValue().get(redisKey);
        System.out.println("val = " + val);

    }

}

测试正常

7，添加Mysql依赖

    <dependency>
      <groupId>com.mysql</groupId>
      <artifactId>mysql-connector-j</artifactId>
      <version>8.0.33</version>
    </dependency>

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

添加配置：

spring:
  data:
    redis:
      host: 47.108.195.246
      port: 6379
      password: redis@2024
      database: 0
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://47.108.195.246:3306/nacos?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=UTC
    username: root
    password: mysql@2024

创建测试类MysqlTest

mport java.util.List;
import java.util.Map;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.jdbc.core.JdbcTemplate;

@SpringBootTest(classes = NccApplication.class)
public class MysqlTest {

	@Autowired
	private JdbcTemplate jdbcTemplate;

	@Test
	void redisTest() {
		List<Map<String, Object>> list = jdbcTemplate.queryForList("SELECT * FROM users");
		System.out.println("list = " + list);
	}

}

完成测试

8，以下是完整的pom.xml
