spring boot 配置全局日期类型转换器

1. 首先自定义一个类型转换器

import org.springframework.core.convert.converter.Converter;import org.springframework.stereotype.Component;import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.Date;

@ComponentpublicclassMyDataConvertimplementsConverter {

　　//这里可以自己灵活变通

    privateString [] pattern = {"yyyy-MM-dd","yyyy年MM月dd日"};

    @Override

    public Date convert(String s) {

        System.out.println("convert");

        for(inti=0;i

            try {

                returnnew SimpleDateFormat(pattern[i]).parse(s);

            } catch (ParseException e) {

                continue;

            }

        }

        returnnull;

    }

}

2.在配置类中注册自定义类型转换器

import com.example.demo.convert.MyDataConvert;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Configuration;import org.springframework.core.convert.support.GenericConversionService;import org.springframework.web.bind.support.ConfigurableWebBindingInitializer;import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter;import javax.annotation.PostConstruct;

@ConfigurationpublicclassWebConfigurerextends WebMvcConfigurationSupport  {

    @Autowired

    private RequestMappingHandlerAdapter handlerAdapter;

    @PostConstruct

    publicvoid initEditableAvlidation() {

        ConfigurableWebBindingInitializer initializer = (ConfigurableWebBindingInitializer)handlerAdapter.getWebBindingInitializer();

        if(initializer.getConversionService()!=null) {

            GenericConversionService genericConversionService = (GenericConversionService)initializer.getConversionService();

            genericConversionService.addConverter(newMyDataConvert());//添加自定义的类型转换器        }

    }

}
