top.tangyh.basic.echo.core.EchoServiceImpl

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean, org.springframework.core.env.EnvironmentCapable, EchoService

public class EchoServiceImpl
extends Object
implements EchoService, org.springframework.core.env.EnvironmentCapable, org.springframework.beans.factory.InitializingBean

字典数据回显工具类 1. 通过反射将obj的字段上标记了@Echo注解的字段解析出来 2. 依次查询待回显的数据 3. 将查询出来结果回显到obj的 @Echo注解的字段中

回显数据的3个步骤：（出现回显失败时，认真debug该方法）

1. parse: 通过反射将obj的字段上标记了 @Echo 注解的字段解析出来, 封装到typeMap中 2. load: 依次查询待回显的数据 3. write: 将查询出来的结果 反射或put 到obj的 字段或echoMap 中

注意：若对象中需要回显的字段之间出现循环引用，很可能发生异常，所以请保证不要出现循环引用！！！

Specified by:

action in interface EchoService

Parameters:

obj - 需要回显的参数，支持 自定义对象(User)、集合(List、Set)、IPage

isUseCache - 是否使用内存缓存

ignoreFields - 忽略字段
