springboot @RequestBody使用JsonSerialize与 JsonDeserialize自定义转参数，处理Date日期格式

JsonDeserialize:

1、请求接收的是一个json，并且由对象接收

@RequestMapping(value = "/query", method = {RequestMethod.POST},consumes = "application/json")
public WebDataListResponse query(@RequestBody(required = true) DataLogQuryEntity dataLogQuryEntity){

2、对象属性的set方法编写注解　　

DataLogQuryEntity对象中需要接受Date类型的对象：

public class DataLogQuryEntity  {

@JsonDeserialize(using = DateJsonDeserializer.class)
public void setStartTime(Date startTime) {
this.startTime = startTime;
}

}

　　注lombok的注意一定要写在setter方法上

3、自定义实现

import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.DeserializationContext;
import com.fasterxml.jackson.databind.JsonDeserializer;
import org.apache.commons.lang3.StringUtils;

import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class DateJsonDeserializer  extends JsonDeserializer<Date> {
public static final SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
@Override
public Date deserialize(JsonParser jsonParser, DeserializationContext ctxt) throws IOException, JsonProcessingException {
try {
if (jsonParser != null && StringUtils.isNotEmpty(jsonParser.getText())) {
return format.parse(jsonParser.getText());
} else {
return null;
}
} catch (Exception e) {
System.out.println(e.getMessage());
throw new RuntimeException(e);
}

}
}

JsonSerialize用法：

1、对象的get方法应用注解

@JsonSerialize(using = CustomDateSerializer.class)
public LocalDateTime getUpdateTime() {
return updateTime;
}

2、自定义实现

import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializerProvider;

import java.io.IOException;
import java.time.LocalDateTime;

public class CustomDateSerializer extends JsonSerializer<LocalDateTime> {
@Override
public void serialize(LocalDateTime value, JsonGenerator gen, SerializerProvider serializers) throws IOException, JsonProcessingException {
gen.writeString(value.toString());
}
}
