Can not deserialize value of type java.util.Date from String异常解决办法

问题描述：今天在用swagger2接口测试文档，调试接口时，传递日期值时报以下异常：

Can not deserialize value of type java.util.Date from String异常

Caused by: com.fasterxml.jackson.databind.exc.InvalidFormatException: Can not deserialize value of type java.util.Date from String "2018-06-14": not a valid representation (error: Failed to parse Date value '2018-06-14': Unparseable date: "2018-06-14")at [Source: java.io.PushbackInputStream@23800c4c; line: 3, column: 21] (through reference chain: com.bootdo.cheng.vo.UserRegisterVO["graduationYear"])at com.fasterxml.jackson.databind.exc.InvalidFormatException.from(InvalidFormatException.java:74)at com.fasterxml.jackson.databind.DeserializationContext.weirdStringException(DeserializationContext.java:1410)at com.fasterxml.jackson.databind.DeserializationContext.handleWeirdStringValue(DeserializationContext.java:926)at com.fasterxml.jackson.databind.deser.std.StdDeserializer._parseDate(StdDeserializer.java:819)at com.fasterxml.jackson.databind.deser.std.StdDeserializer._parseDate(StdDeserializer.java:788)at com.fasterxml.jackson.databind.deser.std.DateDeserializers$DateBasedDeserializer._parseDate(DateDeserializers.java:172)at com.fasterxml.jackson.databind.deser.std.DateDeserializers$DateDeserializer.deserialize(DateDeserializers.java:259)at com.fasterxml.jackson.databind.deser.std.DateDeserializers$DateDeserializer.deserialize(DateDeserializers.java:242)at com.fasterxml.jackson.databind.deser.SettableBeanProperty.deserialize(SettableBeanProperty.java:504)at com.fasterxml.jackson.databind.deser.impl.MethodProperty.deserializeAndSet(MethodProperty.java:104)at com.fasterxml.jackson.databind.deser.BeanDeserializer.deserializeFromObject(BeanDeserializer.java:357)at com.fasterxml.jackson.databind.deser.BeanDeserializer.deserialize(BeanDeserializer.java:148)at com.fasterxml.jackson.databind.ObjectMapper._readMapAndClose(ObjectMapper.java:3814)at com.fasterxml.jackson.databind.ObjectMapper.readValue(ObjectMapper.java:2938)at org.springframework.http.converter.json.AbstractJackson2HttpMessageConverter.readJavaType(AbstractJackson2HttpMessageConverter.java:235)... 78 common frames omitted

如图所示：

问题原因：由于前端传递过来的是日期字符串格式的值，而SpringMVC无法将日期字符串格式的值解析为日期格式

解决方法一：

新增一个类继承 org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter 父类覆写父类的configureMessageConverters方法，增加MappingJackson2HttpMessageConverter类型的对象值

代码如下：

package com.bootdo.common.config;import java.text.DateFormat;
import java.util.ArrayList;
import java.util.List;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.MediaType;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;import com.fasterxml.jackson.databind.ObjectMapper;@Component
class WebConfigurer extends WebMvcConfigurerAdapter {@Overridepublic void configureMessageConverters(List<HttpMessageConverter<?>> converters) {MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter = new MappingJackson2HttpMessageConverter();//设置日期格式ObjectMapper objectMapper = new ObjectMapper();/*SimpleDateFormat smt = new SimpleDateFormat("yyyy-MM-dd");objectMapper.setDateFormat(smt);*/mappingJackson2HttpMessageConverter.setObjectMapper(objectMapper);//设置中文编码格式List<MediaType> list = new ArrayList<MediaType>();list.add(MediaType.APPLICATION_JSON_UTF8);mappingJackson2HttpMessageConverter.setSupportedMediaTypes(list);converters.add(mappingJackson2HttpMessageConverter);super.configureMessageConverters(converters);}}

解决办法二：

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

代码如下：

package com.fhsn.weixin.config;import java.util.ArrayList;
import java.util.List;import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Scope;
import org.springframework.http.MediaType;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;import com.fasterxml.jackson.databind.ObjectMapper;
import com.fhsn.weixin.OAuth2;
import com.fhsn.weixin.Weixin;
import com.fhsn.weixin.cache.ITokenCache;@Configuration
public class WebWeixinConfig {@Beanpublic 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<MediaType> list = new ArrayList<MediaType>();list.add(MediaType.APPLICATION_JSON_UTF8);mappingJackson2HttpMessageConverter.setSupportedMediaTypes(list);return mappingJackson2HttpMessageConverter;}}
