自定义一对一转换器Converter
自定义Converter
@Component("stringToPojoConverter")
public class StringToPojoConverter implements Converter<String, BeanParam> {
@Override
public BeanParam convert(String source) {
String[] split = source.split("-");
BeanParam bean = new BeanParam();
bean.setName(split[0]);
bean.setNote(split[1]);
return bean;
}
}
bean
public class BeanParam {
private String name;
private String note;
// serter、geter
}
配置转换器
<!-- 配置转换器 -->
<bean id="conversionService"
class="org.springframework.context.support.ConversionServiceFactoryBean">
<property name="converters">
<set>
<ref bean="stringToPojoConverter" />
</set>
</property>
</bean>
<mvc:annotation-driven conversion-service="conversionService" />
控制器测试
// http://localhost:8080/springmvc/convertOne2One?beanParam=abc-ef
@RequestMapping("/convertOne2One")
public ModelAndView convertOne2One(BeanParam beanParam) {
ModelAndView mv = new ModelAndView();
mv.setViewName("convert");
return mv;
}
