springboot 中使用fastjson 处理日期

1、导入依赖

<dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.62</version> </dependency>

2、在application.yml中配置时间格式化器(用于处理前台页面传入的日期格式yyyy-MM-dd HH:mm:ss)：

spring: mvc: date-format: yyyy-MM-dd HH:mm:ss

3、配置fastjson 转换器：

package org.hunan; import com.alibaba.fastjson.serializer.SerializerFeature; import com.alibaba.fastjson.support.config.FastJsonConfig; import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter; import org.springframework.context.annotation.Configuration; import org.springframework.format.FormatterRegistry; import org.springframework.http.converter.HttpMessageConverter; import org.springframework.validation.MessageCodesResolver; import org.springframework.validation.Validator; import org.springframework.web.method.support.HandlerMethodArgumentResolver; import org.springframework.web.method.support.HandlerMethodReturnValueHandler; import org.springframework.web.servlet.HandlerExceptionResolver; import org.springframework.web.servlet.config.annotation.*; import java.util.List; /** * Created by Administrator on 2020/10/22 0022. */ @Configuration public class WebMvcConfig implements WebMvcConfigurer { @Override public void configurePathMatch(PathMatchConfigurer pathMatchConfigurer) { } @Override public void configureContentNegotiation(ContentNegotiationConfigurer contentNegotiationConfigurer) { } @Override public void configureAsyncSupport(AsyncSupportConfigurer asyncSupportConfigurer) { } @Override public void configureDefaultServletHandling(DefaultServletHandlerConfigurer defaultServletHandlerConfigurer) { } @Override public void addFormatters(FormatterRegistry formatterRegistry) { } @Override public void addInterceptors(InterceptorRegistry interceptorRegistry) { } @Override public void addResourceHandlers(ResourceHandlerRegistry resourceHandlerRegistry) { } @Override public void addCorsMappings(CorsRegistry corsRegistry) { } @Override public void addViewControllers(ViewControllerRegistry viewControllerRegistry) { } @Override public void configureViewResolvers(ViewResolverRegistry viewResolverRegistry) { } @Override public void addArgumentResolvers(List<HandlerMethodArgumentResolver> list) { } @Override public void addReturnValueHandlers(List<HandlerMethodReturnValueHandler> list) { } @Override public void configureMessageConverters(List<HttpMessageConverter<?>> list) { FastJsonHttpMessageConverter fc = new FastJsonHttpMessageConverter(); FastJsonConfig fastJsonConfig = new FastJsonConfig(); fastJsonConfig.setSerializerFeatures(SerializerFeature.PrettyFormat); fc.setFastJsonConfig(fastJsonConfig); list.add(fc); } @Override public void extendMessageConverters(List<HttpMessageConverter<?>> list) { } @Override public void configureHandlerExceptionResolvers(List<HandlerExceptionResolver> list) { } @Override public void extendHandlerExceptionResolvers(List<HandlerExceptionResolver> list) { } @Override public Validator getValidator() { return null; } @Override public MessageCodesResolver getMessageCodesResolver() { return null; } }

4、实体类上添加注解：

@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss") @JSONField(format = "yyyy-MM-dd HH:mm:ss") private Date date;
