添加生成元数据信息的依赖

           
      
       org.springframework.boot
            
      
       spring-boot-starter
            
      
       2.1.6.RELEASE
          
         
             
      
       org.springframework.boot
              
      
       spring-boot-configuration-processor
              
      
       2.1.6.RELEASE
            
      
       true
          
     

 

配置类

@ConfigurationProperties(prefix = "feilong.hello.format",ignoreUnknownFields = true)public class HelloFormatProperties {    private  int port;    public int getPort() {        return port;    }    public void setPort(int port) {        this.port = port;    }    public final static String HELLO_FORMAT_PROPERTITIES = "feilong.hello.format";    private Map
     
       info;    public Map
      
        getInfo() {        return info;    }    public void setInfo(Map
       
         info) {        this.info = info;    }    @Override    public String toString() {        return "HelloFormatProperties{" +                "info=" + info +                '}';    }}
       
      
     

 

作为自动化配置项, [启动@EnableConfigurationProperties]

 

@Import(feilong.stater.autoconfiguration.FormatAutoConfiguration.class)@EnableConfigurationProperties(feilong.stater.autoconfiguration.HelloFormatProperties.class)@Configurationpublic class HellowAutoConfiguration {    @Bean(name="feilonghelloFormatTemplate")    public feilong.stater.HelloFormatTemplate helloFormatTemplate(feilong.stater.autoconfiguration.HelloFormatProperties helloProperties, feilong.stater.format.IFormatProcessor formatProcessor){        return new feilong.stater.HelloFormatTemplate(helloProperties,formatProcessor);    }}

 

 

 在resources/META-INF/spring.factories下配置自动注入类

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\    feilong.stater.autoconfiguration.HellowAutoConfiguration

　　

最后一步打包成jar,放到私服上.供其他项目引用

注意,打包时会在spring.factories下生成元数据:spring-configuration-metadata.json

这样在其他springboot项目中,application.properties中便可配置.
