上面的, 可根据自己的 starter 的实际依赖来调整.

Java代码

properties 的配置

@ConfigurationProperties(prefix = AppConstant.PROPERTY_PREFIX)
public class WxProperties {
}

@ConfigurationProperties 使用指定的前缀作为你的 starter 服务的配置. 这样子就可以在 application.properties 中, 以 AppConstant.PROPERTY_PREFIX (自定义的一个字符串常量) 作为前缀来配置你的服务.

bean 的配置

/**
 * @author emacsist
 */
@Configuration
@EnableConfigurationProperties(WxProperties.class)
@ConditionalOnClass(WXService.class)
@ConditionalOnProperty(name = AppConstant.PROPERTY_PREFIX + ".enable", havingValue = "true", matchIfMissing = true)
public class WxNoticeAutoConfiguration {
    @Bean
    @ConditionalOnMissingBean(WXService.class)
    public WXService wxService() {
        WXService wxService = new WXService();
        log.info("init {} module ok", WXService.class.getName());
        return wxService;
    }
}

@ConditionalOnClass(WXService.class) 表示存在 WXService.class 时才加载这个配置.

@ConditionalOnProperty(name = AppConstant.PROPERTY_PREFIX + ".enable", havingValue = "true", matchIfMissing = true) 表示配置文件 前缀.enable 的值为 true 时加载, 如果没指定, 则默认为 true.

可以在 application.properties 中配置 AppConstant.PROPERTY_PREFIX.enable=false 来显式禁止自动配置.

配置 META-INF

在 src/main/resources 目录下, 添加一个 META-INF 目录. 然后在 META-INF 目录下创建 spring.factories 文件. 内容如下:

org.springframework.boot.autoconfigure.EnableAutoConfiguration=com.uniweibo.wxnotice.autoconfig.WxNoticeAutoConfiguration

修改为你的自动配置的class即可.

打包安装

time mvn -T 1C -U  clean package -Dmaven.test.skip=true install deploy

上面的 deploy 命令一般只在有内网 nexus Maven 仓库才会到. 即上面的 pom 里的 <distributionManagement> 元素的配置.
