如何使用XML的CXF JAX-RS和Jackson 2配置服务器返回的日期格式？

Question

This took me a lot of effort to figure out so I'm going to answer the question below. This answer doesn't use annotations and does not require creating additional classes.

You put this in your spring xml context configuration:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:jaxrs="http://cxf.apache.org/jaxrs" xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:p="http://www.springframework.org/schema/p"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/jaxrs
http://cxf.apache.org/schemas/jaxrs.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

...

<bean id="jacksonMapper" class="com.fasterxml.jackson.databind.ObjectMapper">
    <property name="dateFormat">
        <bean class="java.text.SimpleDateFormat">
            <constructor-arg type="java.lang.String" value="yyyyMMdd'T'HHmmss.SSSZ"/>
        </bean>
    </property>
</bean>
<bean id="jsonProvider" class="com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider"
      p:mapper-ref="jacksonMapper"/>

...

     <jaxrs:providers>
        <ref bean="jsonProvider"></ref>
     </jaxrs:providers>
  </jaxrs:server>
