chao-cloud-micro: springcloud feign+nacos+seata+sentinel+mybatis-plus+oauth2+security

996icu code style


以 spring-cloud 为基础,集成feign、nacos、seata、sentinel、mybatis-plus 整合单机版分布式事务,附加oauth2.0+security配置

chao-cloud-micro
    ├─api 		//feign接口
    ├─auth 		//微服务oauth2+security 8003(默认不开启,请在gateway打开过滤器 OAuth2GlobalFilter.class)
    ├─gateway 		//微服务网关 8000
    ├─provider 		//服务提供者 8001
    └─consumer		//服务消费者 8002

Step1-导入sql(mysql)

  • 新建数据源 test,导入 sql/test.sql
  • 新建数据源 seata,导入 sql/seata.sql
  • 新建数据源 nacos,导入 sql/nacos.sql
    • 注:nacos为微服务配置中心下一步详细介绍
  • 新建数据源 oauth2,导入 sql/oauth2.sql
    • 注:oauth2为微服务接口权限控制,默认不开启,非本章重点,可忽略。

Step2-配置nacos(nacos@安装手册

1.安装nacos
  • 下载nacos-1.1.3版本 ->nacos-server-1.1.3.zip
  • 解压、修改 conf/application.properties、新增以下5行配置
spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://127.0.0.1/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=root
db.password=123456
  • 启动nacos
    • Linux/Unix/Mac
      • sh startup.sh -m standalone
    • Windows
      • 双击startup.cmd运行文件。
  • 访问nacos http://127.0.0.1:8848/nacos
    • 账号:nacos
    • 密码: nacos
2.配置jvm增加启动参数
-Dspring.cloud.nacos.config.server-addr=127.0.0.1:8848   #你的nacos服务地址 
-Dspring.cloud.nacos.config.namespace=0cdb13f9-8694-49b8-8a37-08b5f1895c6b #你的nacos命名空间(这里是 chao-cloud命名空间 下的那个随机字符串)

Image text

3.修改nacos 配置管理->配置列表->点击chao-cloud
  • chao-cloud-provider.yaml
  • chao-cloud-consumer.yaml
  • chao-cloud-auth.yaml (同上,可忽略)

Image text Image text

Step3-配置seata

1.在 Seata Release 下载相应版本的 Seata Server 并解压
2.修改 conf/registry.conf 配置,将 type 改为 nacos
registry {
  type = "nacos"

  nacos {
    serverAddr = "127.0.0.1:8848"
    namespace = "public"
    cluster = "default"
  }
}

config {
  type = "nacos"

  nacos {
    serverAddr = "127.0.0.1:8848"
    namespace = "public"
    cluster = "default"
  }
}
3.修改 conf/nacos-config.txt配置(上述 nacos.sql 中已经导入、可略过此步骤)

修改 service.vgroup_mapping为自己应用对应的名称;如果有多个服务,添加相应的配置

service.vgroup_mapping.my_test_tx_group=default

#改为 

service.vgroup_mapping.chao-cloud-provider-fescar-service-group=default
service.vgroup_mapping.chao-cloud-consumer-fescar-service-group=default

也可以在 Nacos 配置页面添加,data-id 为 service.vgroup_mapping.${YOUR_SERVICE_NAME}-fescar-service-group, group 为 SEATA_GROUP, 如果不添加该配置,启动后会提示no available server to connect

注意配置文件末尾有空行,需要删除,否则会提示失败,尽管实际上是成功的

4.将 Seata 配置添加到 Nacos 中 (上述 nacos.sql 中已经导入、可略过此步骤)
cd conf
sh nacos-config.sh 127.0.0.1:8848  #127.0.0.1:8848 为你的nacos服务地址

成功后会提示

init nacos config finished, please start seata-server
5.在nacos服务 public 命名空间下添加一个配置(上述 nacos.sql 中已经导入、可略过此步骤)
  • Data Id: registry.type
  • Group: SEATA_GROUP
  • 内容为 nacos 格式选txet
6.启动 Seata Server (windows 请直接点击 bin/seata-server.cmd)
cd ..
sh ./bin/seata-server.sh -p 8091 -m file

启动后在 Nacos 的服务列表下面可以看到一个名为serverAddr的服务

Step4-测试

  1. 启动 gateway
  2. 启动 provider
  3. 启动 consumer
  4. http://localhost:8000/chao-cloud-consumer/test?userId=1
  5. 查看 seata 数据库的 order表 是否有数据,没有则正确

自定义 seata-nacos配置(此步骤可选)

  • 项目的nacos配置和 seata的nacos配置可分开 ->请查看seata/conf/registry.conf
@EnableTxSeata

//yaml 配置
chao:
  cloud:
    tx:
      seata:
        server-addr:  # seata->nacos地址
        namespace: # seata->nacos命名空间  默认  
        cluster:   # seata->集群标识  默认 default
  • 说明
    • 在启动类增加@EnableTxSeata
    • 目前只支持 nacos+feign+seata

注意

1.TxSeataConfig 配置 (原理)

这里是尤其需要注意的,Seata 是通过代理数据源实现事务分支,所以需要配置 io.seata.rm.datasource.DataSourceProxy 的 Bean,且是 @Primary默认的数据源,否则事务不会回滚,无法实现分布式事务

@Data
@ConfigurationProperties(EnableTxSeata.TX_SEATA_PREFIX)
public class TxSeataConfig {

	private String serverAddr;
	private String namespace;
	private String cluster;

	@Bean(initMethod = "init")
	@ConditionalOnMissingBean
	@ConfigurationProperties(prefix = "spring.datasource")
	public DruidDataSource druidDataSource() {
		StaticLog.info("初始化-Seata-DruidDataSource");
		return new DruidDataSource();
	}

	@Primary
	@Bean
	@ConditionalOnMissingBean
	public DataSourceProxy dataSource(DataSource dataSource) {
		return new DataSourceProxy(dataSource);
	}

	@Bean
	@ConditionalOnClass(Feign.class)
	public TxSeataFeignProxy TxSeataProxy() {
		return new TxSeataFeignProxy();
	}
}

2.OAuth 2.0 配置

<!-- oauth2 已经包含 security -->
<dependency>
	<groupId>org.springframework.cloud</groupId>
	<artifactId>spring-cloud-starter-oauth2</artifactId>
</dependency>
  • gateway-> OAuth2GlobalFilter 解开注释
  • gateway-> OAuth2Properties 配置过滤的路径
chao:
  cloud:
    oauth2:
      ant-matchers:
      - /health/**
      - /login/**
  • auth-> AuthorizationServerConfig oauth2认证中心
  • auth-> ResourceServerConfig 启用资源服务
  • auth-> SecurityConfig Security 权限管理(本项目)
  • auth-> MappingAuthProperties 配置路径-> 权限映射
chao:
  cloud:
    oauth2:
      mapping-auth: # 这里的@代表 / ,意为 路径:权限
        @chao-cloud-auth@oauth@user: ROLE_USER
