springmvc实现自定义类型转换器示例

package com.hy.springmvc.entities;import org.springframework.core.convert.converter.Converter;import com.google.gson.Gson;public class DepartmentConvertor implements Converter<String, Department> { @Override public Department convert(String source) {  System.out.println("com.hy.springmvc.entities.DepartmentConvertor: "    + source);  Department department = new Gson().fromJson(source, Department.class);  return department; }}

<bean id="conversionService"  class="org.springframework.context.support.ConversionServiceFactoryBean">  <property name="converters">   <list>    <bean class="com.hy.springmvc.entities.DepartmentConvertor"></bean>   </list>  </property> </bean>

<mvc:annotation-driven conversion-service="conversionService"></mvc:annotation-driven>
