本文介绍了如何在Spring Boot项目中集成Fastjson，并配置日期时间格式化，以正确处理前后台交互的日期字符串，包括引入依赖、配置yml文件、设置Fastjson转换器以及实体类注解的使用。

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;

/**

 */
@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;
