代码背景
小公司新项目加上本人也就两个开发，很多地方用到了字典，于是在网上参考一篇数据字典翻译类，自己记录一下，方便之后项目用到使用。
@Dict注解
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
/**
* @Author: Yin XX
* @Description:

*/
@Target(ElementType.FIELD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Dict {
/**
* 方法描述：数据dataSource
* @return 返回类型： String
*/
String dictDataSource();
/**
* 方法描述：这是返回后Put到josn中的文本key值
* @return 返回类型： String
*/
String dictText() default "";
}
