Cannot deserialize value of type `java.util.Date` from String

今天使用element-ui组件的el-date-picker，提交el-form 到后台，然后时间选项是这样的

后台接收是这样的：

 

但是提交后提示，我时间格式不对  Cannot deserialize value of type `java.util.Date` from String 。。。

百度后解决办法：

新增一个配置类，返回类型为MappingJackson2HttpMessageConverter的bean

 

import java.util.ArrayList;
import java.util.List;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.MediaType;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;

import com.fasterxml.jackson.databind.ObjectMapper;

@Configuration
public class WebConfig {
	
	@Bean
    public MappingJackson2HttpMessageConverter getMappingJackson2HttpMessageConverter() {
    	MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter();
    	//设置日期格式
    	ObjectMapper objectMapper = new ObjectMapper();
    	
    	mappingJackson2HttpMessageConverter.setObjectMapper(objectMapper);
    	//设置中文编码格式
    	List list = new ArrayList();
    	list.add(MediaType.APPLICATION_JSON_UTF8);
    	mappingJackson2HttpMessageConverter.setSupportedMediaTypes(list);
    	return mappingJackson2HttpMessageConverter;
    }

}

问题解决
