springboot项目scanBasePackages和exclude 迁移到配置文件

在实际开发中想把@SpringBootApplication 扫描包 scanBasePackages 和 排除功能exclude 放到配置文件 @Configuration中，方便打jar包(不要@SpringBootApplication)……搜索查询了很久，没有找到方法 手动捂脸…… 最后……如下

如下springboot启动类

@SpringBootApplication(scanBasePackages = { "com.demo.workflow", "com.demo.xiaoxiao.swagger"}, ,exclude = {SecurityAutoConfiguration.class}) 迁移到config配置文件

• 将启动类配置信息(需要删除类的扫码包信息以及需要排除的类SecurityAutoConfiguration )

@SpringBootApplication(scanBasePackages = {
        "org.flowable.ui.modeler.repository",
        "org.flowable.ui.modeler.service",
        "org.flowable.ui.modeler.rest.app",
        "org.flowable.ui.modeler.rest.api",
        "org.flowable.ui.common.service",
        "org.flowable.ui.common.repository",
        "org.flowable.ui.common.tenant",
        "com.demo.workflow",
        "com.demo.xiaoxiao.swagger"}
        , exclude = {SecurityAutoConfiguration.class})
public class Application{
 public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

• 配置文件迁移 扫描的包的注解用@ComponentScan 排除的包用注解@EnableAutoConfiguration(exclude 进行排除

@Configuration
@ComponentScan(basePackages = {
        "org.flowable.ui.modeler.repository",
        "org.flowable.ui.modeler.service",
        "org.flowable.ui.modeler.rest.app",
        "org.flowable.ui.modeler.rest.api",
        "org.flowable.ui.common.service",
        "org.flowable.ui.common.repository",
        "org.flowable.ui.common.tenant",
        "com.demo.workflow",
        "com.demo.skull.swagger"}
        )
@EnableAutoConfiguration(exclude =  {SecurityAutoConfiguration.class})
public class MyAppConfiguration {
}

注意 如下方式迁移是无效的
@ComponentScan(basePackages = {"com.demo.workflow", "com.demo.skull","org.flowable.ui.modeler", "org.flowable.ui.common"}
, excludeFilters = @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = SecurityAutoConfiguration.class)
)

为什么这么迁移？ 其实 很简单，我们看下注解源码就知道了,截取一部分

scanBasePackages 对应的刚好是 @ComponentScan
exclude 对应的刚好是 @EnableAutoConfiguration(exclude

所以将启动类的配置更改到配置中心如上
