spring boot 配置全局日期类型转换器

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

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

@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"};br/>@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.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;

@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
    }
}

}
