自定义springboot 起步依赖

定义start子项目

项目结构
配置自动注册扫描

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
  com.example.start_template.autoconfig.HelloAutoConfiguration

配置类转换：

@ConfigurationProperties(prefix = CustomProperties.CUSTOM_PROFILE_PREFIX)
public class CustomProperties {
    
    

    public static final String CUSTOM_PROFILE_PREFIX = "custom.profile";
    private Map<String, Object> info;

    public Map<String, Object> getInfo() {
    
    
        return info;
    }

    public void setInfo(Map<String, Object> info) {
    
    
        System.out.println("CustomProperties-setInfo" + info.toString());
        this.info = info;
    }
}

选择注入实现：

@Configuration
public class FormatAutoConfiguration {
    
    

    //没有指定的包则进行注入
    @ConditionalOnMissingClass("com.alibaba.fastjson.JSON")
    @Bean
    @Primary
    public FormatProcessor stringFormat(){
    
    
        return new StringFormatProcessor();
    }

    //存在指定的包则进行注入
    @ConditionalOnClass(name = "com.alibaba.fastjson.JSON")
    @Bean
    public FormatProcessor jsonFormat(){
    
    
        return new JsonFormatProcessor();
    }

}

待扫描类：

@Import(FormatAutoConfiguration.class)
@EnableConfigurationProperties(CustomProperties.class)
@Configuration
public class HelloAutoConfiguration {
    
    

    @Bean
    public HelloFormatTemplate helloFormatTemplate(CustomProperties customProperties, FormatProcessor formatProcessor) {
    
    
        return new HelloFormatTemplate(customProperties,formatProcessor);
    }

}

另一项目引入依赖，完成调用：

#自定义配置文件
custom.profile.info.key1=value1
custom.profile.info.key2=value1
custom.profile.info.key3=value1
custom.profile.info.key4=value1

@RestController
public class TestController {
    
    

    @Autowired
    private HelloFormatTemplate helloFormatTemplate;

    @RequestMapping("/get/info")
    public String getMessage(){
    
    
        return helloFormatTemplate.getCustomPropertiesString();
    }
}
