• durid 配置<公钥解密>:
  • class DruidDataSourceWrapper
  • class DruidDataSourceAutoConfigure

@Configuration
@ConfigurationProperties("spring.datasource.druid")

    @Autowired
    private DataSourceProperties basicProperties;

    @Value("${spring.datasource.druid.public_key}")

     */
    @Override

}

• mybatis-plus配置:

mybatis-plus:
  global-config:
    db-config:
      id-type: auto
  configuration:
    auto-mapping-unknown-column-behavior: warning
  mapper-locations: classpath*:mapper/*.xml
  type-aliases-package: com.<name>.finance.ccas.source.entity

其余完整配置

• dubbo 使用样例:

如需指定服务互调取: 加入属性 [url:"dubbo://ip:port"]

• dubbo 生产端

  • 在实现类上加入 @service注解 注意引入包为:com.alibaba.dubbo.config.annotation

• 结尾： 基础功能就差不多就这些了，如生产用可以加入负载，调用链等配置
