###### 直接上例子
```java
// 1. 实体 必须实现 DictEntity
public class UserMember  implements DictEntity {
    // 2. 固定map,用key，转换为value
    @KvConverter({
            @Kv(k="1",v="男"),
            @Kv(k="0",v="女"),
    })
    public int sex;
    
    // 3. 用枚举值，转换为枚举名称
    @EnumConverter(EnumSmall.class)
    public int tx;

    // 4. 邮箱脱敏
    @DesensitizedConverter(EmailDesensitizedAction.class)
    public String email = "2225w@qq.com";
    
    // 5. 手机号码脱敏
    @DesensitizedConverter(PhoneDesensitizedAction.class)
    public String phone = "1357759998";
   
    // 6. 支持1v1对象嵌套，支持map、colloct、array对象嵌套
    UserMember member;
}
```
###### 返回的json
```json
{
  "tx":0,"phone":"135****9998",
  "sex":0,"sexName":"女",
  "member":
  {
    "tx":0,
    "phone":"135****9998",
    "sex":0,
    "sexName":"女",
    "txName":"FF_23",
    "email":"2****@qq.com"
  },
  "txName":"FF_23",
  "email":"2****@qq.com"
}
```

###### 自定义注解,只需3步
```xml
<!--个人觉得，这不算一个步骤。因为，很基操-->
<!--solon添加maven依赖-->
<dependency>
    <groupId>top.rish.converter</groupId>
    <artifactId>dict-converter-solon</artifactId>
    <version>1.0</version>
</dependency>

<!--springboot添加maven依赖-->
<dependency>
    <groupId>top.rish.converter</groupId>
    <artifactId>dict-converter-spring-boot-starter</artifactId>
    <version>1.0</version>
</dependency>
```
```java 
// 1. 定义注解 EnumConverter
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.FIELD)
public @interface EnumConverter {
    // 例如，你想将规则定为：用枚举的value替换为枚举的名称
    Class<? extends Enum<?>> value();

}


// 2. 实现EnumConverter的handler.
public class EnumConverterHandler implements ConvertHandler<EnumConverter> {
    @Override
    public void convert(MetaMap metaMap /* 当前继承了DictEntity对应的一个map【中间产物】 */,
                        DictEntity entity /*当前对象的值*/,
                        Object value /*当前字段的值*/, 
                        FieldWrap fieldWrap /*当前字段的元信息*/,
                        EnumConverter convert /*你的注解,传入的值*/ ) {
        // 这里进行转换为你想要的内容，
        // 对metaMap.put()一下，
        // 该jsonObject就会有你新put的字段了
        Class<? extends Enum<?>> enumClass = convert.value();
        
        Enum<?> ev = RefKit.getEnumByValue(enumClass, value);
        if(ObjKit.isNotEmpty(ev)){
            metaMap.set(fieldWrap.getName()+"Name", Objects.toString(ev));
        }
    }
}

// 3. 注册bean到solon容器
@Configuration
public class Config {

    @Bean
    public KvConverterHandler kvConverterHandler(){
        return new KvConverterHandler();
    }

    @Bean
    public DesensitizedConverterHandler desensitizedConverterHandler(){
        return new DesensitizedConverterHandler();
    }

    @Bean
    public EnumConverterHandler enumConverterHandler(){
        return new EnumConverterHandler();
    }
}
```
