创建启动类，在learning-online-learning-api工程的com.swx.learning包下创建启动类LearningApplication，内容如下：

LearningApplication
@SpringBootApplication
@EnableTransactionManagement
@MapperScan(basePackages = "com.swx.learning.mapper")
@EnableFeignClients(basePackages = "com.swx.learning.client")
public class LearningApplication {
    public static void main(String[] args) {
        SpringApplication.run(LearningApplication.class, args);
    }
}

项目配置信息，在learning-online-learning-api工程的resources下创建bootstrap.yml

bootstrap.yml
spring:
  application:
    name: learning-api
  cloud:
    nacos:
      discovery:
        server-addr: 124.221.23.47:8848
        namespace: learning-online-dev
        group: learning-online-project
      config:
        server-addr: 124.221.23.47:8848
        namespace: learning-online-dev
        group: learning-online-project
        file-extension: yaml
        refresh-enabled: true
        extension-configs:
          - data-id: learning-service-${spring.profiles.active}.yaml
            group: learning-online-project
            refresh: true
        shared-configs:
          - data-id: logging-${spring.profiles.active}.yaml
            group: learning-online-common
            refresh: true
          - data-id: feign-${spring.profiles.active}.yaml
            group: learning-online-common
            refresh: true
  profiles:
    active: dev

日志配置，在learning-online-learning-api工程的resources下创建log4j2-dev.xml

log4j2-dev.xml

基础代码

实体类

使用代码生成工具生成lo_learning表的实体类，将其拷贝到learning-online-learning-model工程的com.swx.learning.model.po包下，暂时所需实体类如下：

  • XcChooseCourse.java
  • XcCourseTables.java
  • XcLearnRecord.java

Mapper层

将代码生成的所有Mapper.java文件拷贝到learning-online-learning-service工程下的com.swx.learning.mapper包下。

将代码生成的所有Mapper.xml文件拷贝到learning-online-learning-service工程下的resources/mapper目录下。

Service层

将代码生成的所有Service和ServiceImpl文件拷贝到learning-online-learning-service工程下的com.swx.learning.service包下。
