自定义转换器
自定义转换器,将 String 转换成 LocalDateTime:
1、实现Converter接口:StringToLocalDateTimeConverter
public class StringToLocalDateTimeConverter implements Converter<String, LocalDateTime> {@Overridepublic LocalDateTime convert(String s) {final DateTimeFormatter dateTimeFormatter =DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");return LocalDateTime.parse(s, dateTimeFormatter);}}
2、在 Spring 的配置文件中配置 conversionService 的 Bean:
<!-- 配置转换器的bean --><bean id="myConverter"class="top.songfang.StringToLocalDateTimeConverter"/><!-- 注册转换器 --><bean id="conversionService" class="org.springframework.context.support.ConversionServiceFactoryBean"><property name="converters"><set><ref bean="myConverter"/></set></property></bean>
3、测试:
定义实体:
// 实体定义public class User{private String name;private LocalDateTime birth;// Setter/Getter}
配置:
<bean id="user" class="top.songfang.User"><property name="birth" value="2020-12-20 12:21:36"/><property name="name" value="风生"/></bean>
测试:
@Testpublic void test() {final User user = context.getBean(User.class);System.out.println(user.getTime());}
