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 }
}
}
