Fastjson提供了兩種自定義序列化的方法:
示例代碼如下:
public class CustomSerializer implements ObjectSerializer {
public void write(JSONSerializer serializer, Object object, Object fieldName, Type fieldType, int features) throws IOException {
// 自定義序列化邏輯
}
}
public class CustomDeserializer implements ObjectDeserializer {
public <T> T deserialze(DefaultJSONParser parser, Type type, Object fieldName) {
// 自定義反序列化邏輯
}
}
// 注冊自定義序列化器和反序列化器
SerializeConfig.getGlobalInstance().put(MyType.class, new CustomSerializer());
ParserConfig.getGlobalInstance().putDeserializer(MyType.class, new CustomDeserializer());
@JSONField
來標記需要自定義序列化和反序列化的字段或方法。這種方法適用于只需對特定字段或方法進行自定義序列化和反序列化邏輯的情況。示例代碼如下:
public class MyType {
@JSONField(serializeUsing = CustomSerializer.class, deserializeUsing = CustomDeserializer.class)
private String field;
// getter and setter
}
public class CustomSerializer implements ContextObjectSerializer {
public void write(JSONSerializer serializer, Object object, BeanContext context) throws IOException {
// 自定義序列化邏輯
}
}
public class CustomDeserializer implements ContextObjectDeserializer {
public <T> T deserialze(DefaultJSONParser parser, Type type, Object fieldName, BeanContext context) {
// 自定義反序列化邏輯
}
}
以上是兩種自定義序列化的方法,根據需求選擇適合的方法進行自定義序列化。
