在系統交互之間，采用Json的數據格式執行協議，來完成數據傳輸，算是前置校驗吧

省去schema文件的編寫，大致內容如下，網上copy的

{
... 
 "vegetables":  { 
   "type":  "array", 
   "items":  {  "$ref":  "#/definitions/veggie"  } 
 } 
   }, 
   "definitions":  { 
 "veggie":  { 
   "type":  "object", 
   "required":  [  "veggieName",  "veggieLike"  ], 
   "properties":  { 
     "veggieName":  { 
       "type":  "string", 
       "description":  "The name of the vegetable." 
     }, 
     "veggieLike":  { 
       "type":  "boolean", 
       "description":  "Do I like this vegetable?" 
     } 
...}

只使用代碼描述，不在進行過多贅述，我不太喜歡說話

抽象出大致要使用的頂級接口Complier，好了我似乎特別喜歡Complier，好多都是它。

public interface Complier {

    void complie(byte[] bytes);
}

實現頂級接口Complier

import com.github.fge.jsonschema.main.JsonSchemaFactory;

public class MyDataComplier implements Complier {

private JsonSchema schema;

private final ObjectMapper objectMapper = new ObjectMapper();

public MyDataComplier() {
    try {
        //讀入自定義的schemas文件
        JsonNode sh = objectMapper.readTree(this.getClass()
                .getClassLoader()
                .getResourceAsStream("schemas/yourJson.json"));
        final JsonSchemaFactory factory = JsonSchemaFactory.byDefault();
        schema = factory.getJsonSchema(sh);
    } catch (Exception e) {

    }
}

@Override
public void complie(byte[] bytes) {
    try {
        JsonNode jsonNode = objectMapper.readTree(bytes);
        //先校驗數據的格式 然后進行業務邏輯的處理
        ProcessingReport report = schema.validate(jsonNode);
        if (!report.isSuccess()) {
            throw new Exception(report.toString());
        }
        //doSomething()
    } catch (Exception e) {

    }
}
}
