使用Spring静态注入实现读取配置工具类新方式

@Component
public class PropertiesUtils {
    private static PropertiesUtils tool;
    @Autowired
    private Environment environment;
    public static String getProperty(String property) {
        return tool.environment.getProperty(property);
    }
    @PostConstruct
    public void init() {
        tool = this;
        tool.environment = this.environment;
    }
}

public class AutoConfig {
    @Bean
    private PropertiesUtils propertiesUtils() {
        return new PropertiesUtils();
    }
}

org.springframework.boot.autoconfigure.EnableAutoConfiguration=com.example.AutoConfig

//可以换成@Configuration,与@Inject配合使用
@Componentpublic 
class XXUtils { 
        //可以换成@Inject/ @Autowired
       @Resource
  private XXXProperties xxxPropertiesAutowired;  
  private static XXXProperties xxxProperties;  
       @PostConstruct 
       public void init() {
              this.xxxPropertiesAutowired = xxxProperties;
       }
}

@Component
public class UrlUtil {
     private static RRJConfig rrjConfig;
    @Autowired
    public void setRRJConfig(RRJConfig rRJConfig) {
    UrlUtil.rrjConfig = rRJConfig;
    }
