#json_scheam_vaild

json_scheam_vaild直接通过使用java bean上添加对应类型json scheam注解，自动生成json schema规范，通过验证用户输入的json字符串工具类

###使用说明:

修改com/sung/json/scheam/impl/JacksonSchema.java  反射包名修改为你自己的

###代码如下:[^code]
```java
Class<JSONValidator> clazz = (Class<JSONValidator>) Class.forName("com.sung.json.scheam.impl.validators."+ className);
```
###使用说明:[^code]
```java
public class Person {

    @JsonNumberSchema(optional = false,minimum = 1,maximum = 200,description = "")//optional = false 必选
    private Integer age;
    //@JsonStringSchema(optional = false,minLength = 1,maxLength = 13)
    @JsonStringSchema(optional = false,pattern = "^(?![0-9]+$)[0-9a-zA-Z-]{1,13}$",description = "^(?![0-9]+$)[0-9a-zA-Z-]{1,13}$&名字前缀，1-13位字符，名称包含只字母、数字和中划线，同时不能由纯数字组成")
    private String name;
