spring4.0.6注入Date的属性编辑器无效

Question

spring

Answer 1

Spring 4.x是支持泛型注入的

Answer 2

属性上加上@DateTimeFormat(pattern="yyyy-MM-dd")

Answer 3

4.0.6的org.springframework.beans.factory.config.CustomEditorConfigurer类中customEditors为Map<Class<?>, Class<? extends PropertyEditor>>,属性值为Class类型，所以注入时会报错.
官方文档中有两种注入方法
1:
//属性编辑类
package example;public class ExoticTypeEditor extends PropertyEditorSupport {    public void setAsText(String text) {
        setValue(new ExoticType(text.toUpperCase()));
    }
}
//配置
<bean class="org.springframework.beans.factory.config.CustomEditorConfigurer">
    <property name="customEditors">
        <map>
            <entry key="example.ExoticType" value="example.ExoticTypeEditor"/>
        </map>
    </property>
</bean>2：
//编辑器注册类
package com.foo.editors.spring;public final class CustomPropertyEditorRegistrar implements PropertyEditorRegistrar {    public void registerCustomEditors(PropertyEditorRegistry registry) {        //注册编辑器实例
        registry.registerCustomEditor(ExoticType.class, new ExoticTypeEditor());    }
}
//配置
<bean class="org.springframework.beans.factory.config.CustomEditorConfigurer">
    <property name="propertyEditorRegistrars">
        <list>
            <ref bean="customPropertyEditorRegistrar"/>
        </list>
    </property>
</bean><bean id="customPropertyEditorRegistrar"
    class="com.foo.editors.spring.CustomPropertyEditorRegistrar"/>
