The content of this article is about how to configure the global date type converter (code) in spring boot. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

1. First customize a type converter

import org.springframework.core.convert.converter.Converter;
import org.springframework.stereotype.Component;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

@Component
public class MyDataConvert implements Converter<String, Date> {
　　//这里可以自己灵活变通
    private String [] pattern = {"yyyy-MM-dd","yyyy年MM月dd日"};
    @Override
    public Date convert(String s) {
        System.out.println("convert");
        for (int i=0;i<pattern.length;i++){
            try {
                return  new SimpleDateFormat(pattern[i]).parse(s);
            } catch (ParseException e) {
                continue;
            }
        }
        return null;
    }
}

2. Register the custom type converter in the configuration class

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;

@Configuration
public class WebConfigurer extends WebMvcConfigurationSupport  {

    @Autowired
    private RequestMappingHandlerAdapter handlerAdapter;

    @PostConstruct
    public void initEditableAvlidation() {

        ConfigurableWebBindingInitializer initializer = (ConfigurableWebBindingInitializer)handlerAdapter.getWebBindingInitializer();
        if(initializer.getConversionService()!=null) {
            GenericConversionService genericConversionService = (GenericConversionService)initializer.getConversionService();
            genericConversionService.addConverter(new MyDataConvert());//添加自定义的类型转换器
        }
    }


}
